Abstract ：
Building integrated photovoltaic-thermal (BIPVT) technology is an efficient form of solar energy utilization, which realizes self-energy supply and holds good development prospects. In this paper, a novel BIPVT module based on micro heat pipe array and BIPVT near-zero energy building are proposed. A matching multi-energy complementary energy supply system is also proposed for this building. The building and energy supply sys-tem models were built using TRNSYS. The load characteristics of BIPVT buildings were studied by analyzing the heat transfer process of BIPVT components. The energy-saving rate of the building was also calculated using the method of near-zero energy building evaluation index. The accumulated cooling load and heating load of the buildings throughout the year show that those of the BIPVT buildings are 8.6% higher than those of the benchmark building. Comparison of the energy consumption results shows that the annual cumulative energy consumption of the BIPVT building is 32.3% lower compared to the benchmark building's. In addition, 61.2% of the energy required for year-round refrigeration, heating, and electricity can be supplied by this system. The energy consumption index of the BIPVT building is 70.26 kWh / (m2 center dot a). Compared with the benchmark building, the BIPVT building energy saving rate is 76.6% and the building energy efficiency improvement rate is 32.3%.

Abstract ：
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.

Abstract ：
We analyzed three forms of heating system which is under the similar meteorological condition by testing the temperature distribution of the radiant surface, the distribution of the indoor air temperature in the horizontal and vertical directions, the interior surface temperature of the non-heated surface of the room, and the indoor and outdoor temperature and humidity. The PMV and PPD indexes were used to evaluate the thermal comfort of laboratory in winter. The results show that with other condition unchanged, the human body stands and relaxes and dressed in winter indoor clothes (clothing thermal resistance for 1.2–1.5 clo), the new floor heating room comfortable air temperature would be 17–21 °C, and the optimal water supply temperature is recommended to be 40–43 °C. © 2020, Springer Nature Singapore Pte Ltd.

Abstract ：
This paper presents a solar photovoltaic–thermal cogeneration component based on parallel flow tube with tiny porous channels and micro-heat tube array (MHPA-PV/T). The core heat transfer component effectively combines micro-heat tube array and parallel flow tube with tiny porous channels and applies to solar photovoltaic/thermal system. The heat collection efficiency and power generation efficiency of the two systems under instantaneous and all-day operation conditions are studied and analyzed, respectively. The results show that the instantaneous heat collecting efficiency of the tiny channel flow tube with the MHPA-PV/T components’ maximum value is 36.8% and increases by 14.6% and the photovoltaic increases by 5.5%. The daily average photovoltaic conversion efficiency improves by 9.8% in the all-day efficiency test system, and the daily average photo-thermal conversion efficiency enhances up to 11.1%, compared to the component of airfoil tube in the testing system. The MHPA-PV/T components based on parallel flow tube with tiny porous channels provide a theoretical basis for the practical application and popularization of the solar cogeneration technology in the future. © 2020, Springer Nature Singapore Pte Ltd.

Abstract ：
In the present study, an optimization model of double-layered microchannel heat sink (DL-MCHS) is developed based on a derivative-free method, BOBYQA algorithm, which solves optimization problems without using derivatives of the objective function. Overall, thermal resistance R-T and pumping power are adopted as multi-objective functions to search for optimal design variables. The effect of weight factors on results of optimization is discussed. With the increase of increases. Moreover, the effect of design variables of the bottom layers on flow and heat transfer performance is more obvious than that of the upper layers. Finally, the Pareto fronts of counter-flow and cross-flow DL-MCHS are calculated. Results indicate that counter-flow heat sink shows better thermal performance compared to cross-flow heat sink under the same pumping power consumption.

Abstract ：
The thermal control and heat management of lithium-ion (Li-ion) batteries in high-power applications remains a challenge to be addressed before widespread commercialization. To solve the problem, micro heat pipe array (MHPA) is used to design Li-ion battery packs cooling system. Experiments were conducted utilizing Li-ion battery packs under open conditions with constant current of 18 A(1 C) and 36 A(2 C). The temperatures were measured with and without micro heat pipe arrays during the charge-discharge cycle. At the rates of 1 C and 2 C, the temperature results of the Li-ion battery packs validate the effectiveness of the functional heat conducting material-MHPA in lowering the temperature of the battery packs, as well as the temperature difference inside the packs, the temperature and temperature difference could be controlled within 40 and 5 respectively. Thus, they preliminarily solve the influence of temperature on battery life and capacity. Based on the experimental data, the heat in one of the 2 C working conditions was calculated, and the convection heat dissipation by MHPA reached 40% of the heat generation in the pack. © All right reserved.

Abstract ：
A new system based on solar photovoltaic/thermal-ground source heat pump (PV/T-GSHP) was proposed to solve the problems of energy shortage and high energy-consuming buildings in China. The operation performance of the PV/T-GSHP system in a demonstration project in Dalian of China was studied and energy saving performance was analyzed.

Abstract ：
The charge-discharge performance of lithium-ion battery as a vehicle power battery is affected by low-temperature. Heating lithium-ion battery at low-temperature conditions toincrease the temperature can improve the charge-discharge peformace and available capacity ratio. To study the effect of the charge-discharge performance of lithium-ion battery with new heating method using heat pipes, the performance tests were conducted under the different low-temperatures. The results showed that the charge-discharge performance dropped significantly in low-temperatures, and the charge-discharge performance could be visibly improved by heating with heat pipes. Heating method with heat pipes could significantly reduce the heating time. Under the condition of-30, the heating power of 30W could increase the battery rise temperature by 30 within 20 minutes, the discharge capacity and charge capacity increased 39.95% and 86.44%, respectively. This study provided a new technical method and data for using lithium-ion batteries efficiently in low-temperature. © 2017, Chemical Industry Press. All right reserved.
