Comparison of Performance between R290 and R417A in Heat Pump Air Conditioning Water Heater Combination

Abstract:

The natural refrigerant R29O and mixed refrigerant R417A is currently approved ideal substitutes of R22, The performance of R290 and R410A in the same heat pump air conditioning water heater combination was studied experimentally, heating capacity, cooling capacity, power input, COP ,discharge pressure, suction pressure,discharge temperature were measured, the performance of heat pump air conditioning water heater combination at standard air condition and varied inlet-water temperature was analyzed .The results show that the most appropriate charge mass of R290 is only 52% of R417A in the same systems ,so using r290 more environmentally friendly.The coefficient of performance (COP) is higher than R417A in the same capacity, so using r290 have lower energy consumption, more energy-saving. Compressor discharge pressure and temperatures of R290 is lower than R417A in the same inlet-water temperature, so using r290 favors the system security operation. But the performance of R290 influenced by the inlet water temperature more obvious than R417A, it's not very suitable for the occasion of high inlet-water temperature.
