Refrigeration system belongs to the core parts of the environmental testing equipment. In this article, the composition and the principle for the refrigeration system of HLT/SR2000 environmental testing equipment were outlined, and the calculation method of the load for refrigeration system and thermodynamics parameter for state point were given, the optimization type - selection of compressors was illustrated in brief. Through practical operation of this system, it shows that the various indicators of refrigeration system can fully satisfy requirements of design. In addition, the available indicators of temperature can be superior to the user requirements through a third party testing.
