将CO2、R170和R41应用于跨临界空气源热泵热水器系统的性能对比研究
Comparison of air-source heat pump water heater performance with transcritical cycle using CO2, R170 and R41 as refrigerant
摘要
Abstract
On the basis of an air-source heat pump water heater (ASHPWH) system, a thermodynamic model used to calculate system performance is developed. Then, the performances and exergy efficiencies of a transcritical cycle with CO2, R170 and R41 are investigated and compared. The results indicate that the COPheat and exergy efficiencies of R41 (R170) system are about 31.77％(4.9％) and 23.34％(3.6％) higher than that of CO2 system under the same condition. R41 and R170 also have obvious advantages in increasing the heating capacity. Moreover, the optimum high pressure of system with R41 (R170) is more than 35％(43％) lower compared to that with CO2. So, besides CO2, R41 and R170 are also promising refrigerants for an ASHPWH system.关键词
