A quartz crystal microbalance (QCM) technique was used to measure amounts of adsorbed and desorbed water vapor in a moist air to a thin layer of adsorbent consolidated with silica-gel micro particles on the quartz crystal coated with thin gold electrodes. First, measured relative isothermal equilibrium adsorption was confirmed to reproduce the catalogue data of the silica gel. Then, the adsorption and desorption rates to the layer were measured under a condition of a step change of the surrounding relative humidity. Overall mass transfer resistance which related to both the mass diffusion in the particle and the mass transfer in the boundary layer was revealed by the obtained time constants of these reactions. The resistance decreased with the increase of the velocity, and it became a negligible quantity in the boundary layer when the flow rate was above 0.1 m s⁻¹. Finally, correlations were proposed to predict these resistances.

The objective of this paper is to present experimental results on distribution characteristics of solar irradiation absorbed by the narrow channel wall of desiccant rotor. Experiments are performed with the channel made by the silica gel and the poly propylene (PP). Energy absorption rate is measured in conditions of different channel lengths, incident irradiation angles, air temperatures, and humidity. The result of the present measurement for silica gel is equal to that of the previous study [J. Li, Y. Hamamoto, and H. Mori, Transactions of the Japan Society of Refrigerating and Air Conditioning Engineers 32(2), 149-154 (2015)], which is conducted using laser light as a source. It is confirmed the previous prediction model of laser light is suitable for this solar light system. Moreover, the previous model is improved, because the rate of laser for PP is larger than that of solar. These models are applicable to predict desorption rate of the water vapor in a desiccant rotor heated directly by the concentrated solar irradiation. The results show that the absorption rates of solar irradiation and red laser are equal to each other in the silica gel channel. The absorption rates of the laser irradiation are larger than that of the solar irradiation for PP materials. It is clear that the solar irradiation absorption rate cannot be influenced by the ambient humidity and temperature. The prediction model of the absorption efficiency based on the laser for silica gel channel can reproduce well the absorption efficiency of experiment based on solar irradiation. In the case of PP, the difference between the prediction and the measurement is observed.

A novel high-performance heat exchanger using multiport extruded tubes which have parallel refrigerant mini-channels has recently been developed for air conditioning systems. In a multiport tube for evaporators, due to unequal heat transfer rates among parallel channels, vapor–liquid two-phase refrigerant flow tends to be distributed unevenly. This flow maldistribution makes it difficult to predict heat exchange performance accurately. Hence, it is important to clarify the characteristics of flow boiling heat transfer and flow maldistribution in unequally heated parallel mini-channels. In the present study, experiments were performed on flow boiling of HFC32 and HFC134a in unequally heated two parallel circular mini-channels connected with T-junction headers. When heat flux was unequal between two channels, mass flow and inlet quality maldistributions were recognized. These maldistributions were more intense with widening inequality in channel heat fluxes. In addition, the effects of the averaged flow rate of the two channels, the quality before branching, and refrigerant properties on flow maldistribution were examined. Based on the obtained characteristics, correlation equations were developed to reproduce the mass flow rates and inlet qualities in the respective channels. In boiling heat transfer, dryout tended to occur in a relatively wide portion of the higher-heated channel because of flow rate reduction. Then, heat transfer became degraded especially near the outlet, even at the same averaged heat flux of two channels as the value at which dryout did not occur under equally heated condition.

Observation of Liquid Film on Fiber Flocked Cross-fin Type Heat Exchanger Fins and Evaporative Heat Transfer Characteristics

Language：English   Publishing type：Research paper (scientific journal)  

A novel high performance refrigerant-air heat exchanger employing multiport extruded tubes which have parallel refrigerant mini-channels has recently been developed for heat pump systems. In evaporators, the inequality in heat loads among parallel refrigerant channels causes also inequalities in flow rates of refrigerant. This flow maldistribution induced by unequal heating not only makes it difficult to predict heat exchange performance accurately but also often leads to the deterioration of the refrigerant heat transfer. In the present study, an experiment was conducted on flow boiling heat transfer of a refrigerant R410A flowing in parallel two mini-channels individually heated by hot water flows. When the parallel channels were heated unequally, the heat transfer rate from the hot water to the refrigerant in the channel with higher degree of wall superheat did not change so much, while that with lower degree of wall superheat remarkably decreased from the equally-heated condition. Consequently, the two-channels-mean heat transfer rate dropped off with expanding the inequality in degree of wall superheat between the channels. The deterioration of the mean heat transfer coefficient under the unequally-heated condition was significant at a high mean flow rate condition which required a large heat transfer rate for evaporation.

In industrial fields, heat source over 130°C are widely needed, and for this development of industrial high-temperature heat pump systems has been promoted. For the heat release process in such the heat pump systems, it is considered to use of a plate heat exchanger (PHE) in which a high pressure working refrigerant flows. In this study, to examine the effect of chevron angle on heat transfer of refrigerants flowing in chevron PHEs at supercritical pressure and high subcritical pressure, experiments were conducted using a chevron PHE with a chevron angle 75°. The measured heat transfer coefficient was compared with the data of three chevron PHEs with respective chevron angles 30°, 47.5° and 65° obtained previously. The effect of chevron angle on heat transfer at 65° and more was smaller than that at less than 65°, and the heat transfer coefficient in 75° PHE was almost the same with that in 65° PHE, considering difference in hydraulic diameter between the PHEs. Furthermore, the value of heat transfer coefficient achieved in 65° or 75° PHE was estimated to be almost maximum between 0° to 90°. On the other hand, the friction factor of 75° PHE was markedly larger than that of 65° PHE.

A novel heat exchanger using parallel small refrigerant channels has recently been developed for air conditioning systems. To do this, it is necessary to clarify the characteristics of boiling heat transfer in non-uniformly heated parallel mini-channels. In this study, experiments on flow boiling in non-uniformly heated two parallel mini-channels were carried out and the characteristics of flow distribution and flow boiling heat transfer were investigated. When the difference of heat flux between the two channels was large, the maldistribution of different flow rates and inlet qualities of the channels occurred. In the higher heated channel, flow rate was lower than the average flow rate of the two channels and heat transfer coefficient decreased especially near the outlet.

Herein, a measuring device was constructed to obtain condensation heat transfer characteristics at mass flow rates below 100 kg/(m²·s) for a 1 × 1 mm² flow path constituting a flat multiport heat transfer tube. The condensation heat transfer characteristics of HFC134a were experimentally determined under flow rate conditions including low mass rate of 40 kg/(m²·s). The condensation heat transfer coefficient in a single tube was partly different from that observed in a flat multiport tube. Also, we found that the smaller the flow rate (or the smaller the heat flow rate), the higher the heat transfer coefficient becomes. In the low quality range, as the vapor quality decreased, the smaller the flow rate, the higher the maximum value with high quality. This feature was remarkable when the heat flux was small. Regarding the tendency of the single tube to reach the local maximum value of the heat transfer coefficient in the low quality range, the region where the slug flow occurs corresponds well to the quality region where the condensation heat transfer shows a local maximum, with reference to what has been observed in previous studies.

In industrial fields, heat source over 130°C are widely needed, and for this the development of industrial high-temperature heat pump systems has been promoted. For the heat release process in such the heat pump systems, the authors have studied on cooling heat transfer at supercritical pressures and condensation heat transfer at high subcritical pressures of refrigerants flowing in chevron-type plate heat exchangers (PHEs). In this study, to examine the effect of chevron angle on condensation heat transfer of HFC134a at high subcritical pressures, experiments were conducted using chevron PHEs with the chevron angles 30°, 47.5° and 65°. In the experiments, condensation heat transfer coefficients were obtained in the wide range of bulk fluid enthalpy comprising whole the saturated region, at the pressures of reduced pressures 0.65 and 0.80, and the mass flow rates of 7 and 11 kg/min. The condensation heat transfer coefficient increased with chevron angle, similarly with those at low subcritical pressures. The increment ratio of the condensation heat transfer coefficient against chevron angle was compared with that of condensation heat transfer coefficient from a conventional correlation developed based on low subcritical pressures data and that of cooling heat transfer coefficient at a supercritical pressure from experiments.

Abstract: This paper presents the basic properties and adsorption characteristics of metallic surface media which is the porous anodic aluminum oxide film on the aluminum plate. Measurements are performed to clarify the equilibrium adsorption and adsorption rate of the material. It is examined that the equilibrium adsorption of the material is approximately one tenth of that of silica gel type A. From a view of the static characteristics, it is found that the material doesn’t work effectively in the adsorption cycle as same as the silica gel does. However, from a view of the dynamic characteristics, it is shown that the cooling capacity of the cycle using the material becomes 10 % higher than that of silica gel. Because the adsorption rate of the material is much higher than that of the silica gel.

Summary: Demand of the humidity control has increased rapidly to have a comfortable space and a safety for a food processing plant. The paper presents a brief review of the systems for dehumidifying and humidifying, and the significance to control humidity and temperature independently for energy saving. It is suitable to apply the absorption and adsorption process to the humidity control. Moisture transportation mechanism in the sorption process was explained. Some studies of the desiccant elements and hybrid systems those are composed of adsorption chiller and desiccant dehumidifier are introduced. The hybrid system can be driven by the thermal energy at temperature of 55 deg.C and the energy efficiency improved 30% compared with the cooling dehumidifier system.

Summary: Precise information such as local temperature, humidity and amount of adsorbed water in a desiccant rotor is significant to improve the rotor and system performance. The paper presents a theoretical dynamic analysis model of heat and mass transfer in a rotor to clarify the design aspects and performance of high efficient systems. The influences of rotor speed, adsorption/desorption time ratio, airflow path patterns and air conditions on rotor performance are discussed. There is an optimum angle of each process zone and an optimum desorption side air flow rate becoming a maximum amount of adsorption. Hybrid system composed of a vapor compression cooling system and desiccant dehumidifier has the potential to improve COP value up to 24% compared with non-hybrid system.
