摘要
通过能量方程分析R134a和R1234yf太阳能辐照度、蒸发器温度和环境温度等因素对系统性能的影响。研究结果表明:R134a的COP略高于R1234yf,而R1234yf的排气温度低于R134a,因此在太阳能热泵中R1234yf可代替R134a。
The energy equations were used to analyze the effects of R134a and R1234yf solar irradiance,evaporator temperature and ambient temperature on system performance.The results show that the COP of R134a is slightly higher than that of R1234yf,while the exhaust temperature of R1234yf is lower than that of R134a.Therefore,R1234yf can replace R134a in solar heat pump.
