R134a/R134a复叠式空气源热泵系统性能分析
Performance Analysis of R134a/R134a Cascade Air-source Heat Pump System
摘要
Abstract
A cascade air-source heat pump system is introduc ed which used R134a and R134a to instead of coal-fired boiler in north China. The thermodynamic cycle process is analyzed. According to the thermodynamic theoretical analysis, the COP change with evaporation condensation temperature is calculated in different evaporation temperature, condensation temperature and heat-transfer temperature difference of condenser-evaporator. An optimum condensation temperature of low temperature cycle and an optimum mass flow ratio is calculated. According to the conclusion of theoretical analysis, we optimize the cascade air-source heat pump system.关键词
