RESEARCH ON DYNAMIC CHARACTERISTICS OF THE AIR-CONDITIONING SYSTEMS WITH CONTINUOUS CAPACITY CONTROLLING DEVICE

摘要

On the basis of analyzing the capacity control method by shifting the composition of non-azeotropic refrigerant mixtures can realize a continuous adjustment of a device output to match the building load as the variable outside temperature in theory. Then, the couple relationship among the parameters of every unit of the air-conditioning system with a distillation device for shifting composition using the mixtures has been deeply discussed. Based on the conservation equations of real fluid and combined with the feature of the system units, their mathematical models are established respectively, and then the discrete formula are obtained.
