In order to further improve the performance of groundwater source heat pump units according to different operating conditions, the mathematical model of system optimization is established based on the analysis of operating characteristics of units and the annual cost total cost as the objective function according to the technical and economic optimization criteria, and the calculation program . On the premise of ensuring the unit safety and reliability to meet the cooling and heating load requirements of the building, the key operating parameters and components of the system are optimized and calculated according to the different groundwater temperature and depth. The method takes into account the reliability and economy of the heating and cooling operation, and can achieve the optimal matching of various components in the system. Compared with the traditional design method, this method can greatly improve the performance of the unit
