摘要 ：
Currently, the alternative refrigerant in air conditioning systems has become a global problem, and air as a natural working fluid has several advantages of zero ODP, low GWP and satisfactory thermodynamic properties, thus it is a long-term development. However, the poor performance of reverse Brayton air cycle limits their application, and how to improve the performance is the main problem we must face at present. Thus, enhancing the components' efficiency and improving the system comprehensive performance have become the most effective way. The output power produced by the expander can be used for coaxial compressors, such as tur-boexpander compressor (TEC), turbocharger, and rotary vane compressor-expander (ROVCE). What's more, amounts of new technological approaches have been used to improve the performance of the systems such as regeneration, multi-stage compression, mixed working fluid, water removal and integrated system. In addition, thermodynamic optimization methods have become one of the most important approaches to reduce the irre-versible losses and enhance the system performance. At present, reverse Brayton air cycle machines have been applied in various fields such as food freezing, transportation, heat pump, refrigerator, and dryer, etc. With the increasingly stringent environmental laws and regulations, the air cycle system will have a wide perspective application in the future.

摘要 ：
The leaking safety of air conditioner using R290 has been a research hotspot in recent years, one method to lower the risk of explosion after leakage is utilizing ventilation. For fresh air conditioner, it's common to use thermal anemometry and differential pressure flowmeters to measure ventilation flow rate. However, there is non-negligible error especially under low air volume flow rate conditions. In this paper, a novel integral-type air conditioner with heat recovery using R290 is proposed. And the relevant influencing parameters are analyzed and experimentally studied. The results show that tracer gas method is an effective way to measure ventilation flow rate, and the novel integral-type air conditioner can meet the needs of the ventilation standards. The air volume flow rates of indoor unit fan and outdoor unit fan are dominant factors affecting ventilation flow rate. The outlet area of exhaust air duct is more sensitive than the inlet area of fresh air duct in exerting influence on ventilation flow rate, while the indoor temperature has a mild impact on ventilation flow rate.

摘要 ：
In recent years, the energy consumption problem in China has become increasingly prominent and district heating systems have received more and more attention compared to distributed heating systems. The traditional district heating system has disadvantages such as high heat loss, high energy consumption and few available heat sources. For this reason, fifth-generation district heating systems, also known as ultra-low temperature district heating systems, have been developed and designed to reduce the supply temperature of hot water, reduce the heat loss of the system, increase the available low-grade heat sources and improve the performance of the system. This paper reviews the literature on the Research and development and practical application of fifth-generation district heating systems in recent decades and elaborates on the research progress of fifth-generation district heating systems, to help relevant researchers to understand better and study fifth-generation district heating systems and to guide and promote their energyefficient application in district heating.

摘要 ：
As a clean and sustainable electrified heating technology, air source heat pump (ASHP) has been widely used in household in China. However, some problems occurred with the commonly used water loop system, such as low efficiency, complicated structure, more likely to be frozen and burst as well as high electric energy consumption, etc. In this paper, a new air source heat pump with multigroup heat pipe radiators (ASHPMP) was presented. In ASHPMP system, the condenser and heat pipe were coupled together to form a new type of heat radiation terminal, which was named as heat pipe radiators, multiple terminals driven by the compressor provided heat for several rooms. An experimental apparatus of the ASHPMP system was developed and the experiment was carried out in residential buildings also, and R410A was used in the heat pump and R134a was used in heat pipes. The influence of temperature, pressure of heat pump and heat pipe on the heating performance of ASHPMP under frosting/defrosting condition was analysed. The results showed that the new system can operate stably under outdoor temperatures of -12.7 & DEG;C to 6.5 & DEG;C. As the indoor temperature was set at 20 & DEG;C, the heating coefficient of performance (heating COP) could reach up to 3.15 with outdoor temperature -12.7 & DEG;C, and it was 6.73 with outdoor temperature 6.5 & DEG;C.
