摘要 ：
In this study, a compact ice thermal storage device that combines multichannel flat tube and closed rectangular fins is designed to improve solidification performance. To analyze the heat transfer characteristics and visualize the ice formation process, a numerical model was formulated and solved using enthalpyporosity method. The temperature distribution, liquid fraction, and ice front evolution were studied during solidification process. The effect of heat transfer fluid on the performance of storage device at different inlet temperatures and flow rates was numerically investigated. Results show that when the inlet temperature was reduced from -3 degrees C to -6 degrees C, the ice packing factor increased by 32.2% and the storage power forms a linear relationship with the inlet temperature. When the flow rate was increased from 0.1 m(3)/h to 0.2 m(3)/h, the ice packing factor increased by 8.7% but the effect of flow rate was less obvious than the inlet temperature. Furthermore, the heat transfer characteristics of closed rectangular fins were compared with traditional longitudinal fins. We found that the former can achieve more uniform temperature distribution and a higher ice formation rate. The average solidification enhancement ratios of the both are 2.28 and 2.08, respectively, the former being 9.6% higher than the latter. (C) 2021 Elsevier Ltd. All rights reserved.

摘要 ：
As the main source of heat loss of flat-plate solar air collectors (FPSACs), single glazing cover reduces the thermal performance of FPSAC. This situation becomes serious when the ambient temperature is low or the inlet temperature is high. A double glass cover with good thermal insulation is a good solution. This work aims to investigate the thermal performance of double glazing FPSAC at low ambient temperature and high inlet temperature. The thermal performance of four FPSACs with single glazing (Model 1), double glazing filled with air (Model 2), double glazing filled with argon (Model 3), and vacuum glazing (Model 4) as the glass cover at different ambient temperatures, different heat transfer air (HTA) inlet temperatures, and different HTA volume flow rates are studied and compared. Result demonstrates that Models 2, 3, and 4 have better thermal performance at low ambient temperature and high inlet tem-perature compared with Model 1. When the inlet temperature is 65 degrees C and ambient temperature is -10 degrees C, the thermal efficiencies of Models 2, 3, and 4 are 1.65, 1.72, and 2.29 times higher than that of Model 1, respectively. The efficiency factor and total heat loss coefficient of Model 4 are 0.62707 and 2.21745, respectively. (C) 2021 Elsevier Ltd. All rights reserved.

摘要 ：
A novel thermal storage solar air heater (TSSAH) is proposed in this study. This TSSAH is composed of a vacuum glass tube, flat micro-heat pipe arrays (FMHPA), and a thermal storage material (i.e., paraffin) with a phase change temperature of 58 °C. The FMHPA acts as the core heat transfer component. Considering the low heat conductivity coefficient of paraffin, louver fins are utilized to enhance heat transfer. Thermal performance is analyzed and discussed. During thermal collection, natural convection evidently contributes to enhancing heat transfer. Increasing solar radiation intensity can improve collection efficiency. Thermal collection efficiency increases from 70.22% to 77.28% when solar radiation is increased from 675 W/m2 to 835 W/m2 under an ambient temperature range of 20.8 °C–23.3 °C. A high ambient temperature results in high collection efficiency that can reach 80.59%. During thermal discharge, enhancing the air volumetric flow rate can evidently increase the amount of useful energy and shorten discharge time. From 80 m3/h to 170 m3/h, the amount of useful energy is increased from 335 W to 550 W, and discharge time is shortened from 309 min to 195 min under inlet temperatures ranging from 24.1 °C to 24.2 °C. A high inlet temperature generates a high outlet temperature but decreases the amount of useful energy. From 19.7 °C to 32.0 °C, outlet temperature is increased from 30.4 °C to 36.6 °C, and the amount of useful energy is reduced from 692 W to 287 W at an air volumetric flow rate of 200 m3/h. During thermal discharge, the average amount of useful energy can reach 692 W at an inlet temperature of 19.7 °C and an air volumetric flow rate of 200 m3/h, indicating that the proposed TSSAH can release heat quickly. In the experiment scale, the discharged heat is 6150–6450 kJ at a phase change material temperature scale of 85 °C–35 °C. © 2021 Elsevier Ltd

摘要 ：
A new type of photovoltaic (PV)/thermal (PV/T) air evaporator based on micro heat pipe arrays (MHPAs) and a PV/T air dual heat source direct-expansion heat pump system that can achieve heating, refrigeration, and PV power generation were developed. System performance was experimentally investigated. Results showed that the MHPAs exerted a significant cooling effect on the PV modules, which were cooled by 31.6 degrees C under the experimental conditions, with a low longitudinal temperature difference of 2.1 degrees C. The increase in PV efficiency was 5.3%. The evaporator can receive heat from solar energy and air energy under appropriate ambient temperature, and the average heat collection efficiency was 106.1%. The average heating coefficients of performance (COP) of the heat pump in solar (5), combined solar and air (SA), and air (A) modes were 2.8, 2.1, and 2, respectively, under typical heating conditions during winter. Average PV efficiency values in 5 and SA modes were 13.3% and 6.8%, respectively. The average cooling COP was 2.2 and the average PV efficiency was 11.2% under typical cooling conditions during summer. The performance difference and control strategy in various modes and seasons were summarized. This research provides data to support the practical application of heat pump systems.

摘要 ：
提出了1种基于微热管阵列的地板辐射供暖系统,建立了供暖单元传热模型,利用实验数据验证了模型的可靠性。并对该辐射供暖传热过程及关键影响因素进行了模拟与分析,得到了供水温度和循环流速对供暖性能的影响。当流速为0.2 m/s,不同供水温度下,地板表面温度的实验数据与模拟数据最大差值为1.6℃。地板表面温度均随着供水温度的增大增幅明显;在相同供水温度下,地板表面温度受循环流速影响较小。在供水温度为40℃,流速为0.2 m/s时,模拟地面温度在23.9～29.9℃之间,热媒输送通道细小通道扁管上方地板表面温度较高。提出地暖结构的优化方法,以减少地板温度不均匀性。

摘要 ：
Air-phase change thermal storage devices are in great demand in the fields of crop drying, flue gas waste heat recovery and building heating. However, the current research on air-phase change thermal storage devices is few and the structure is mostly flat. Based on previous experimental studies, this study used numerical simulation methods to study the thermal performance of four structures of multichannel channel flat tube phase change thermal storage devices to ease the problems of irrational heat transfer structure and low compact factor. The compact factor of the device is improved by changing the height of the flat tube ribs. The effectiveness and specific power are used as evaluation indicators. The results show that when the length of the multichannel flat tube is perpendicular to the direction of gravity and the air is injected from the side, the performance of the device is greatly exerted. Compared with the original research, the phase change completion time is improved by 20.59%. The results show that 0.03 m is a reasonable flat tube rib height. In this case, the compact factor is 61.5%. © 2021, Science Press. All right reserved.
