Experimental Investigation on the Two-stage Compression Heat Pump Water Heater System with Refrigerant Injection
Nowadays heat pump water heater becomes a very hot topic in hot water industry. However it still has many problems such as higher condensing temperature, large-scale operation conditions and lower COP in cold regions. Based on these problems, the paper presents a prototype assembled with a two-stage rotary compressor which can be used in cold regions. The working principle and the basic feature...
متن کاملExperimental Investigation on the Performance of Ground-source Heat Pump with the Refrigerant R410A
Nowadays, in some small and medium-sized heat pumps, refrigerant R410A has been used widely because of the good thermodynamic performance and environmental protection. Firstly the principles of the system and the characteristics of refrigerant has been demonstrates. The paper has set up a heat pump system with the refrigerant R410A and the performance parameters under different working conditio...
متن کاملControl Method Of Circulating Refrigerant Amount For Heat Pump System
A heat pump system requires proper refrigerant charge amount. Once refrigerant is charged into a heat pump system, its charge amount is fixed. For this reason, prediction of optimal refrigerant charge amount is very important in order to yield best performance. Too low charge amount degrades capacity of heat pump. On the other hand, excessive charge amount decreases coefficient of performance (...

متن کاملExperimental Investigation on the Influence of Refrigerant Charge on the Performance of Trans-critical CO2 Water-Water Heat Pump
For the environmentally aware, natural refrigerant such as CO2 is recommended and pursued by researchers for refrigerators. In this paper, a transcritical CO2 heat pump system was set up to investigate the influence of refrigerant charge on the performance of a small-sized heat pump water heater. The transcritical CO2 heat pump system was composed of a rotary compressor, a tube-in-tube evaporat...
