R134a/CO2 cascade heat pump system, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established the mathematical model of the system and each parameter, and studied at different low temperature condensation temperature, evaporation temperature, high temperature condensation temperature, intermediate heat exchange temperature difference and The performance changes of the heat pump system under the high and low temperature mass flow ratios. The results show that the coefficient of performance (COP) of the cascade heat pump system increases with the increase of the low temperature evaporating temperature and the decrease of the high temperature condensation temperature. The temperature difference of the intermediate heat exchange increases and decreases; while the change trend of the mass flow ratio of the high and low temperature stages is opposite to that, and there is an optimal intermediate temperature that maximizes the COP of the system.
