The micro-element simulation method of heat exchanger commonly used in refrigeration and air-conditioning industry was proposed. On the basis of the above, the thermodynamic model of heat exchanger micro-element and its heat exchanger under heating, cooling and cooling dehumidification conditions And fluid mechanics model. The method of dynamic simulation and solution using the above model is introduced. Compared with the traditional calculation methods and measured results, the rationality of the model is demonstrated.
