Abstract：The cascade heat pump system has been widely concerned in the field of industrial energy saving because of its high temperature raising ability.As the core component of the system,evaporative condenser has obvious influence on both high and low temperature cycles,and the complex and diverse heat transfer processes bring challenges to the establishment of numerical models.According to different heat transfer forms,the numerical model of plate evaporative condenser is established by using the method of zone modeling and lumped parameter method.The results show that under experimental conditions,when the plate spacing increases from 2.0 mm to 2.9 mm,the change of heat transfer coefficient and heat transfer area in the evaporation-condensing heat transfer zone is greater than that in other zones,which indicates that evaporation-condensing heat transfer is the dominant factor in the heat transfer process of plate evaporative condenser.
