Design practice and analysis of heat-source-tower heat pump air conditioning in hospital buildings

Taking the construction of a hospital in the hot summer and cold winter zone as an example, the HDY-SMAD software is used to calculate the heating and cooling loads, as well as the annual dynamic loads. Through comparison of the schemes, it is determined to use a heat recovery type heat-source-tower heat pump unit as the cold and heat source for the air conditioning system. The design, selection, control, and operation maintenance of the heat-source-tower heat pump air conditioning system are presented. Based on the actual measurement data, the practical operating efficiency of the heat-source-tower heat pump unit is analysed, and the key design points of the heat-source-tower heat pump air conditioning system are summarized.
