    Language:English  

    This paper presents theoretical and experimental investigation of an adsorption cooling system to predict the cycle performance of one bed adsorber based on the equilibrium condition. For this particular study, activated carbon-ethanol pair was chosen as the adsorbent-refrigerant pair because of a high adsorption capacity of activated carbons against ethanol. The experiment was conducted on five different pre-cooling and pre-heating settings. The experiments carried out were divided to two sections. First, the preliminary experiments were carried out on two extreme conditions. For the first extreme condition, the adsorption and desorption process were carried out without pre-cooling and pre-heating. Whilst for the second extreme condition, the adsorbent was pre-cooled and pre-heated until the adsorbent reach adsorption and desorption temperature. Then the experiments were carried out with three different time of pre-cooling/pre-heating time which was selected based on the preliminary experiments. The heat balance were analyzed critically and the optimum cycle time, namely the pre-cooling and pre-heating time for each adsorption and desorption process is discussed by identifying the suitable adsorbent pressure and temperature of the system.

    R1132(E) (trans-1,2-difluoroethylene, C2H2F2) is a potential next generation refrigerant to be utilized in air conditioning applications. This hydrofluoroolefin (HFO) refrigerant possesses an extremely low-GWP value below 1 and it is an excellent candidate for replacing R32 in blends such as R410A, which are subjected to local and international greenhouse gas regulations for limiting global warming. Two isochoric apparatus were used to measure the saturation pressures of R1132(E) from 240 K to its critical temperature. At the critical temperature, the critical pressure of R1132(E) was also directly measured. Twenty-four saturation pressures including the critical point were used for optimizing a Wagner-type equation representing the saturation pressure curve. The absolute average deviation of the saturation pressures of R1132(E) predicted by the model using the fitted parameters and the experimental data is 0.02%. The optimized Wagner-type equation of saturation pressures is used for determining the acentric factor of R1132(E) as 0.2433, which is further utilized for the prediction of the saturation pressures using the Peng-Robinson cubic equation of state within an absolute average deviation of 0.31%.

    Multi-effect distillation (MED) systems are considered to be the most energy-efficient thermal desalination methods. This paper introduces the development of a novel thermal desalination system for performance superior to MED systems for the same operating temperature limits. Such an unprecedented achievement was attained by upgrading the heat source using the chemical potential of adsorption phenomena. The proposed Adsorption Heat Transformer (AHT) cycle hybridized with Multi-effect distillation system (AHT-MED) exhibits higher performance ratio and water production rate than a conventional MED system for the same heating source and sink. The heat generated by the heat of adsorption with the temperature higher than the heat source is supplied to the first effect of the MED system, thus, extending the temperature difference between the Top Brine Temperature (TBT) and Bottom Brine Temperature (BBT). The higher temperature difference offers more number of effects, with the equivalent temperature difference between the effects (ΔTe) as the design parameter. Using the low-temperature heat source (as low as 58 °C), the system can employ an increased number of effects (as high as 11) due to the supply of heat at an increased temperature of around 80 °C. The proposed system achieves a higher performance ratio (approximately 5.4) and water production rate (2 kg/s) compared to the standalone MED system (PR: 4.2, WPR: 1 kg/s) with the number of effects of the hybrid system as 10 at constant interstage temperature difference between the standalone and hybrid systems. This novel AHT-MED system opens up new possibilities for low-temperature heat source-driven thermal desalination with significantly improved performance.

     More details

    Language:Others  

    Fresh fruits and vegetables are perishable and possess short life under ambient conditions. Post-harvest losses are one of the major concerns in the storage of fruits and vegetables. In this regard, proper control of temperature and humidity is required to reduce post-harvest losses and enhance the shelf life of fruit and vegetables with the finest quality, quantity, and nutritive attributes. Several options such as vapor compression-based air-conditioning systems have been studied and implemented worldwide for possible storage of fruits and vegetables but consume a huge amount of energy and degrading the environment. Therefore, in this study, the energy-efficient standalone desiccant air conditioning (DAC) and Maisotsenko cycle-based desiccant air conditioning (M-DAC) systems were explored from the viewpoint of potential storage of fruits and vegetables. The systems analysis to check the feasibility was carried out in the climatic conditions of Multan, Pakistan. The proposed systems were thermodynamically explored from the viewpoint of ideal temperature and humidity control storage zones, cooling capacity, and coefficient of performance (COP). The results appreciably showed that the M-DAC system performed relatively better than the proposed standalone DAC system. It was found that the cooling capacity and COP of the M-DAC system were found 32.5 kJ/kg and 1.07, respectively, as compared with standalone DAC.

    Indoor air humidity plays a vital role in determining occupants’ health and industrial product quality. Removing excess humidity by adsorption dehumidification is still facing a challenge in finding a suitable material with high adsorption capacity and low regeneration temperature. In this study, the theoretical dehumidification capacity of prepared acorn nutshell-based activated carbons was calculated and compared with silica gel type RD and RD-2060. The calculation was based on the outdoor air condition in two Asian capital cities: Jakarta and Tokyo. The theoretical study found that prepared activated carbon has better dehumidification performance under Jakarta conditions using regeneration temperatures of less than 60°C. Under Tokyo conditions, activated carbon shows auspicious performance during the summer season. Compared with silica gels, acorn nutshell-based activated carbon has a better dehumidification capacity to process high humidity ambient air with a lower regeneration temperature.

    In this study, we evaluated the performance of low Global Warming Potential (GWP) refrigerant R1234yf on the activated carbon (MSC‐30) for adsorption heating applications. The ad-sorption isotherms of MSC‐30/R1234yf were measured using a constant‐volume–variable‐pressure (CVVP) method from very low relative pressure to the practical operating ranges. The data were fitted with several isotherm models using non‐linear curve fitting. An improved equilibrium model was employed to investigate the influence of dead thermal masses, i.e., the heat exchanger assembly and the non‐adsorbing part of the adsorbent. The model employed the model for the isosteric heat of adsorption where the adsorbed phase volume was accounted for. The performance of the heat pump was compared with MSC‐30/R134a pair using the data from the literature. The analysis cov-ered the desorption temperature ranging from 60 °C to 90 °C, with the evaporation temperature at 5 °C and the adsorption temperature and condensation temperature set to 30 °C. It was observed that the adsorption isotherms of R1234yf on MSC‐30 were relatively lower than those of R134a by approximately 12&#37;. The coefficient of performance (COP) of the selected pair was found to vary from 0.03 to 0.35 depending on the heat source temperature. We demonstrated that due to lower latent heat, MSC‐30/R1234yf pair exhibits slightly lower cycle performance compared to the MSC‐ 30/R134a pair. However, the widespread adaptation of environmentally friendly R1234yf in auto-mobile heat pump systems may call for the implementation of adsorption systems such as the direct hybridization using a single refrigerant. The isotherm and performance data presented in this work will be essential for such applications.

    Poultry are one of the most vulnerable species of its kind once the temperature‐humidity nexus is explored. This is so because the broilers lack sweat glands as compared to humans and undergo panting process to mitigate their latent heat (moisture produced in the body) in the air. As a result, moisture production inside poultry house needs to be maintained to avoid any serious health and welfare complications. Several strategies such as compressor‐based air‐conditioning systems have been implemented worldwide to attenuate the heat stress in poultry, but these are not economical. Therefore, this study focuses on the development of low‐cost and environmentally friendly improved evaporative cooling systems (DEC, IEC, MEC) from the viewpoint of heat stress in poultry houses. Thermodynamic analysis of these systems was carried out for the climatic conditions of Multan, Pakistan. The results appreciably controlled the environmental conditions which showed that for the months of April, May, and June, the decrease in temperature by direct evapo-rative cooling (DEC), indirect evaporative cooling (IEC), and Maisotsenko‐Cycle evaporative cooling (MEC) systems is 7–10 °C, 5–6.5 °C, and 9.5–12 °C, respectively. In case of July, August, and September, the decrease in temperature by DEC, IEC, and MEC systems is 5.5–7 °C, 3.5–4.5 °C, and 7–7.5 °C, respectively. In addition, drop in temperature‐humidity index (THI) values by DEC, IEC, and MEC is 3.5–9 °C, 3–7 °C, and 5.5–10 °C, respectively for all months. Optimum temperature and relative humidity conditions are determined for poultry birds and thereby, systems’ performance is thermodynamically evaluated for poultry farms from the viewpoint of THI, temperature‐humid-ity‐velocity index (THVI), and thermal exposure time (ET). From the analysis, it is concluded that MEC system performed relatively better than others due to its ability of dew‐point cooling and achieved THI threshold limit with reasonable temperature and humidity indexes.

    The urge to replace hydrofluorocarbons which possess high global warming potentials has taken center stage in the air conditioning industry due to both international and local policies such as the Kigali Amendment and Japan’s revised Fluorinated Gas law. This has prompted the exploration of novel refrigerants as well as their mixtures to create high performance environmentally friendly alternatives. These refrigerants can be integrated into existing systems as ‘drop in’ refrigerants, which provide a simpler and low cost substitution process to replace environmentally harmful refrigerants such as R410a. R410a is currently a widely used refrigerant in air conditioning systems, but is to be phased out of use under the Kigali Amendment by the late 2040s. Thus to compare the suitability of replacing this refrigerant with environmentally friendly ‘drop in’ alternatives, a preliminary baseline investigation on a mechanical vapor compression chiller with R410a is conducted via performance and exergy indicators. The testing procedure utilized Air Conditioning, Heating and Refrigeration Standard 551/591 which revealed an optimum charge amount of 0.70 kg with a peak performance near 88&#37; of full capacity. The heat exchanger overall heat transfer coefficients showed varying trends, whilst the exergy destruction was as expected highest for the compressor.

    The performance of an adsorption system using Maxsorb III + ethanol pair is investigated for practical heat pump applications. An adsorption system using a single bed with a single evaporator/condenser is employed and the performance of the system is assessed for various regeneration temperatures (80 °C, 70 °C and 60 °C). The impact of the adsorption time on the performance of the selected pair is further evaluated. The potential application of the present adsorbent + adsorbate pair is the automobile air-conditioning system where the exhaust waste heat will be recovered to operate the adsorption system. Thus, antifreeze fluid is employed as the heat transfer medium for the adsorber and the evaporator/condenser heat exchanger. A mathematical model is developed to estimate the uptake amount from the experimental data. The sensible heat change (thermal mass), the superheating of the refrigerant in the adsorber, the adsorber heat leak and the heat rejection to the heat transfer medium are accounted for. The uptake amount is further verified using the classical p–T–q diagram. For operation using 30 °C adsorber coolant inlet and 15 °C chilled water inlet, the cooling capacity of the present system ranges from 15 to 35 W for the adsorption times of 600 s and 300 s, respectively. It is observed that the regeneration temperature significantly influences the net uptake of the system. The maximum net uptake is recorded to be about 0.995 kg/kg for the regeneration temperature of 80 °C. The system is further assessed using the ratio of the cooling capacity to the adsorption heat.

    After publishing our articles on the studies of the vapor–liquid phase distribution in a header type evaporator consisting of upward [refer to Wijayanta et al., 2016] and downward [refer to Wijayanta et al., 2017] minichannel-branching conduits, we were motivated to extend the work to the heating load acting on the branches because till date, it is believed to cause maldistribution. Refrigerant R134a experiments with heating loads from 50 to 300 W on the branches were performed. The vapor quality in the test section inlet was maintained between approximately 0.1 and 0.4. Although a larger phase separation occurred in the header at the maximum heating load of 300 W at a vapor quality in the test section inlet of 0.41, it was notable that the geometry configuration had a stronger effect on the phase distribution.

    Experimental validation of simulated adsorber/desorber beds for sorption cooling applications is essential to obtain reliable results. We have conducted rigorous simulation of the adsorption process occurring in a finned tube adsorber utilizing 2D-axisymmetric geometry. The adsorber uses activated carbon–ethanol as adsorbent–refrigerant pair. It is cooled with water at nearly 30 °C and experiencing a sharp pressure increase of ethanol from 0.95 kPa initially to 6 kPa. The simulated temperatures at adsorbent thicknesses of 0, 1, 5 and 10 mm from tube outer diameter showed an increase in adsorbent temperature up to 20 °C from its initial temperature. They were slightly higher at start of adsorption and were consistent with experimental data at higher flow time. The validated CFD model will serve as a base for evaluating and optimizing activated carbon–ethanol adsorption cooling cycle. It can be extended also to different adsorber designs and other adsorbent–adsorbate pairs.

    Innovative Design and Performance of Three-Bed Two-Stage Adsorption Cycle under Optimized Cycle Time
    This paper presents an innovative design of a three-bed two-stage silica gel-water based adsorption cycle aiming to minimize the overall size of four-bed two-stage cycle. One heat exchanger bed was removed from former four-bed two-stage system and operational strategy was taken to increase the adsorption time compare to desorption time in the proposed design. A simulation model for the proposed cycle was developed in order to analyze the influence of cycle time on the performance of the system in terms of specific cooling power (SCP) and coefficient of performance (COP). The cycle time was optimized to obtain the maximum SCP for different heat source temperatures using the particle swarm optimization (PSO) method. Sensitivity analysis of the cycle time was conducted using contour plot of SCP and chilled water outlet temperature for driving heat source temperature at 55°C. Optimize results were compared with the results of four-bed two-stage cycle. It was found that the SCP was increased for the proposed cycle over the whole range of regeneration temperature. The proposed cycle seems advantageous from the economic viewpoint due to its improved performance and reduced volume.

    Thermodynamic analysis of adsorption cooling cycle using consolidated composite adsorbents - ethanol pairs
    ©2006-2016 Asian Research Publishing Network (ARPN). This study deals with the thermodynamic analysis of adsorption cooling cycle using consolidated composite adsorbents-ethanol pairs. The studied composites are named as composite A (50&#37; Maxsorb III, 40&#37; expanded graphite (EG), 10&#37; binder) and composite C (70&#37; Maxsorb III, 20&#37; expanded graphite (EG), 10&#37; binder). The Dubinin-Radushkevich (D-R) and Dubinin Astakhov (D-A) equation are used to draw pressure-temperature-concentration (P-T-W) diagrams of the assorted pairs. The specific cooling effect (SCE) and coefficient of performance (COP) of both pairs have been simulated for desorption temperatures ranging from 40 to 90 °C at different evaporator temperatures along with a heat sink at 30 °C by considering a time independent thermodynamic model. The maximum COPs of composite A-ethanol and composite C-ethanol based cooling systems are found to be 0.69 and 0.765, respectively.

    Desiccant air-conditioning system for storage of fruits and vegetables: Pakistan preview
    © 2015, Novel Carbon Resource Sciences. All rights reserved. In the present study the desiccant air-conditioning system has been investigated for the on-farm storage of fruits and vegetables in Pakistan. In this regard, ideal storage zone for the studied agricultural products is established in order to ascertain the system applicability. The dehumidification performance of the silica-gel based desiccant wheel has been analysed with low regeneration temperature (50°C. by using the model of Beccali et. al. Three environmental conditions (A: highly humid, B: moderately humid &amp; C: less humid. are considered for the analysis of desiccant air-conditioning system. The latent and sensible loads of air-conditioning are achieved by the silica-gel desiccant wheel dehumidification and Maisotsenko cycle evaporative cooling respectively. The results of the study envisaged that desiccant wheel performs higher dehumidification in climatic condition ‘A’ due to higher ambient air relative humidity as compared to the other climatic conditions. However, higher heat energy is required for its regeneration in the climatic condition ‘A’. This study concluded that the desiccant air-conditioning system can be efficiently used for on-farm storage of fruits and vegetables in Pakistan. Also, the renewable energy sources of the country like solar energy and bio-gas can be potentially harvested for the regeneration of desiccant wheel. The study further proposes the use of hybrid desiccant air-conditioning system where standalone DAC system cannot achieve the sensible load.

    Performance investigation of a finned tube adsorber employing activated carbon-ethanol pair
    This study presents 2D-axisymmetric heat and mass transfer simulations of a finned tube adsorber employing activated carbon-ethanol as the adsorbent-refrigerant pair. The simulation is carried out with Ansys-Fluent v16.2 and the mathematical model consists of mass, momentum and energy conservation equations as well as confirmed adsorption isotherms and adsorption kinetics from measured experimental data. The simulated temperatures at different adsorbent thicknesses agreed fairly with those measured in an adsorption chiller setup in our laboratory. Moreover performance investigation is performed for heating, cooling and evaporation temperature of 80, 30 and 15 °C, respectively. The cooling capacity reached 245.9 W/kgAC whereas COP is found to be 0.42. The CFD simulation will allow design and performance optimization of the finned tube adsorber for adsorption chiller applications. It can be extended also to different absorber-heat exchanger designs and different adsorbent-refrigerant pairs.

    Overview of adsorption cooling system based on activated carbon - alcohol pair
    © 2015, Novel Carbon Resource Sciences. All rights reserved. The depletion of ozone layers and climate problems have been calling for rapid developments in chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HFCs) free air conditioning and heat pump technologies. Using environmental benign refrigerants such as alcohol in adsorption air-conditioning systems will reduced the production of unwanted ozone depleting substances, whilst activated carbon as adsorbent can achieve higher adsorption capacity and rapid adsorption uptake rates. Additionally, it’s also environmental friendly and harmless. From this viewpoint, utilization of activated carbon adsorption system using natural alcohol as refrigerants has been in demand. The researchers put efforts to enhance the performance of adsorption systems by modification in adsorbent properties, optimizing the adsorbers’ heat exchanger design, and so on towards making this technology competitive with the available cooling system in the market. The objective of this paper is to review on the past efforts of various kinds of researches and methods used to validate the efficiency and suitability of activated carbon as the adsorbent material, with ethanol/methanol for cooling and refrigerant applications.

    We have devised a method that employs surface- and self-capacitive sensing principles for touch detection with a single-layered capacitive touch panel. In this method, a single electrode layer consisting of a stripe-shaped one-dimensional electrode array was used to enable multi-touch detection, and a capacitive sensing circuit that uses a trans-impedance amplifier was selected to simplify the circuit structure of the touch panel. The results indicate that the number of the panel fabrication processes and the amount of the touch electrode material required can be reduced by half by using the proposed method.

    Dynamic simulation on a mechanical/thermal compression hybrid air-conditioning cycle
    In the study, we propose a hybrid air-conditioning cycle of mechanical vapour compression and thermal vapour compression. In the bottoming cycle, the refrigerant is compressed by a mechanical compressor from the evaporator to the medium pressure condenser. In the topping cycle, the other refrigerant is compressed by adsorption phenomena, where low temperature heat is used as a driving force, from the medium pressure condenser to the higher pressure condenser. R 1234ze is the refrigerant of the mechanical compression cycle, while CO2 is the refrigerant of the thermally compression cycle, where the activated carbon is the adorbent of CO2. Based on the measured adsorption kinetics of CO2 on the activated carbon, the system is modelled using MATLAB/SIMULINK. The dynamic characteristics of the system is investigated by simulation, and the reduction in mechanical power for the mechanical compressor is revealed.

    The cycle time optimization of a novel dual evaporator type three-bed adsorption chiller
    Copyright © 2010 by the Japan Society of Refrigeration and Air Conditioning Engineering (JSRAE). The novel, dual evaporator type three-bed adsorption chiller was proposed for the enhancement of the performance of adsorption chillers. The chiller is equipped with two evaporators, three adsorbent beds, and a condenser. The evaporators work at different pressure levels, which enhances the working range of the adsorbate concentration. It was predicted that the specific cooling capacity and the coefficient of performance of the dual evaporator type three-bed adsorption chiller enhanced by 50&#37; and by 70&#37;, respectively, compared with the conventional, two-bed single-stage adsorption chiller at the same operating conditions. The aim of the study was to further increase the specific cooling capacity of the dual evaporator type three-bed adsorption chiller by the optimization of the operating conditions. It is known that the cooling capacity of adsorption chillers can be maximized by the optimal cycle time. In the study, the particle swarm optimization was applied to the simulation of the dual evaporator type three-bed adsorption chiller and the optimal cycle time of the chiller was found. The results showed that the performance improvement by the optimization was significant in the case of driving heat source temperature under 75°C.

    Application of ammonia-water absorption cycle to transfer cooling and heating at ambient temperature
    Copyright © 2010 by the Japan Society of Refrigeration and Air Conditioning Engineering (JSRAE). Utilizing wasted heat is an important issue to reduce primary fuel consumption. Because wasted heat sources are not always located near heat demand, it is required to transport thermal energy efficiently. The authors proposed an application of absorption cycle to heat transportation. In contrast with conventional chilled water transportation, the proposed absorption system has the generator-condenser pair at the heat source side while the evaporator-absorber pair at the demand side, and transfers absorption solutions between them. The solution transportation can transfer thermal energy which is converted into the difference of solution concentration. In this study, the proposed system named STA is expanded to supply heating from the absorber as well, which enhances the COP and reduces primary fuel consumption. STA combined with refuse incineration power generation was investigated to utilize steam from the incineration to provide power, cooling and heating simultaneously. The primary fuel substitution is estimated to be 1.7 times as much as that of power generation only system.

    Improvement of adsorption heat exchangers by the enhancement of contact points between adsorbent and surface
    Copyright © 2010 by the Japan Society of Refrigeration and Air Conditioning Engineering (JSRAE). In this study, we are aiming at the improvement of heat exchangers for the adsorption heat pump. To achieve it, it is important to reduce thermal contact resistance between adsorbent and heat transfer surface. The thermal contact resistance can be reduced by increasing the contact points between adsorbents and heat transfer surface. To increase the contact points, four patterns of heat transfer surface geometry were examined. They are flat surface, V-shaped surface, oblong surface, and arc shaped surface, which have one, two, three and maximum contact points, respectively. The flat surface is the one used by the conventional heat exchanger, and the arc shaped surface is the ideal one. The heat conduction in the adsorbent (silica gel) bed was predicted by mathematical simulation. The structure of adsorbent bed was the hexagonal closest packing. For the fundamental analysis, a two dimensional model was developed, and steady-state simulation was performed. The results showed that V-shaped surface could increase heat flux by 10 &#37;. In addition, the reduction of the thermal contact resistance was more effective on the thinner adsorbent layer than that on the thicker one.

    Multi-bed adsorption heat pump cycles and their optimal operation
    © 2010 by Nova Science Publishers, Inc. All rights reserved. The chapter consists of two parts. The first part describes advanced adsorption heat pump cycles. The second part presents cycle simulations with optimization to maximize cooling effect. Multi-stage adsorption heat pump cycles are expected to utilize low temperature heat of 50-70 degC. Two-stage cycle and three-stage cycle have been investigated experimentally to clarify appropriate range of heat source temperature. Furthermore, new single stage cycles are proposed based on an idea of reheat scheme, where single stage cycle operates as quasi-two stage cycle. It can expand the temperature range for lower side. The other interesting idea is single stage cycle with three beds in contrast with two beds of conventional single stage cycle. The third bed runs twice as quickly as the other beds to adsorb more vapor from the evaporator. The process of mass recovery from desorption side to adsorption side has an important role in the cycles. Configuration, operation and performance of the cycles are described in the first part. In the second part, adsorption cycles have some control variables for the operation such as cycle time allocation for adsorption, desorption, precooling, preheating processes. It means that cycle has freedom to maximize the performance under given external conditions. It was, however, difficult to attain the optimum due to large freedom of the system. The authors succeeded to employ a nonlinear optimization technique named Particle Swarm Optimization to find optimal time allocation. The method, optimal settings of the parameters and optimal performance are discussed.
