The Application of EASY5 Software to Simulate the Operating Characteristics of Parallel-Flow Condensing Unit

摘要

MicroChannel heat exchanger has become a hot issue at present, while it is rarely used in the field of industrial cooling and air conditioning. This paper took the dynamic simulation of parallel-flow condensing unit as an example, mainly focused on the introduction to the basic principles, characteristics and main modeling method of multiphase flow library of EASY5 software, the simulation results were presented. The results showed that the dynamic response of system state parameters was corresponding to practical situation, indicating the dynamic response was reasonable. This can provide references for the research and matching technique of microchannel heat exchanger.
