Abstract：The small computer room of the civil air defense project is selected as the research object to analyze the feasibility of the ground source heat pump system with buried pipes in the envelope structure for treating part of the waste heat of the civil air defense project.Based on the Trnsys software,the heat load characteristics of the computer room are calculated.Considering the economy,it is proposed to adopt the composite ground source heat pump system of embedded pipes+air conditioning reservoir to jointly handle the load in the project,and the equipment such as the ground source side water pump,the load side water pump and the heat pump unit are selected based on the dynamic load calculation results.By using iterative calculation,the operation mode of the composite system is determined,and the variation characteristics of the inlet and outlet water temperatures of the buried pipe and the user side,COP,heat exchange capacity,flow rate and energy consumption during the operation of the system are analyzed.The results show that all the indicators during the operation of the system are within the acceptable range,confirming the feasibility of the ground source heat pump system with buried pipes in the envelope structure for treating part of the waste heat of the civil air defense project.
