摘　　要：对于建造类似于冷库的空调试验间,在冷间冷却设备负荷计算中,要求规定时间将库温降到一定值,因此围护结构之地面热负荷不能按照稳态传热计算,文中建立了实验室地面的传热数学模型,利用ANSYS Workbench有限元热分析软件对实验室地面进行非稳态传热模拟研究,求出地面内部的温度场及上表面的热流量,通过和传统冷库维护结构的设计计算进行比对分析,为后续实验室空调试验间制冷机组的选型提供了一个重要依据。For building air-conditioning test rooms similar to cold storage, In the load calculation of the cold-room cooling equipment,Required to reduce the library temperature to a certain value at the specified time, Therefore, the ground heat load of the enclosure structure cannot be calculated according to the steady-state heat transfer, The authors developed a mathematical model of heat transfer on the laboratory ground, Nonstable heat transfer simulation studies on the laboratory ground using ANSYS Workbench finite element thermal analysis software,Find out the temperature field inside the surface and the heat flow of the upper surface, By comparing with the design and calculation of the traditional cold storage maintenance structure, It provides an important basis for the selection of laboratory air conditioning test room.
