Abstract

The invention belongs to the field of test devices of cold water units, and specifically relates to a test device of a cold water unit suitable for a low temperature refrigerating medium. The device comprises a cooling water system connected with a condenser in the tested cold water unit and further comprises a refrigerant water system connected with an evaporator in the tested cold water unit. A heat exchanging system for heat exchange is arranged between the cooling water system and the refrigerant water system. The test device uses heat generated by the condenser side of the cold water unit adequately and balances heat generated by the condenser side of the cold water unit and refrigeration capacity generated by the evaporator side through the heat exchanging system so as to improve the economical efficiency of operation of the test device of the cold water unit and reduce the test cost greatly. The test device can fulfill the test requirements of different refrigerating mediums for the water cooling cold and hot water unit only by injecting low temperature refrigerating mediums such as a salt liquor and the like into a refrigerant box, and is simple and convenient to operate, and the low temperature refrigerating medium is available at room temperature without having to be cooled particularly.

Description

technical field [0001] The invention belongs to the field of chiller test devices, and in particular relates to a chiller test device suitable for low-temperature secondary refrigerants. Background technique [0002] In the traditional chiller test device, the evaporator side of the chiller is equipped with a refrigerant water tank for balancing the cooling capacity generated on the evaporator side, and an electric heater is installed in the refrigerant water tank. In order to meet the test requirements, the electric heater of the refrigerant water tank The heating capacity is relatively large, so it consumes a lot of energy during work, resulting in high operating costs for the chiller test device. Contents of the invention [0003] The purpose of the present invention is to provide a chiller test device suitable for low-temperature brine. This device balances the heat generated by the condenser side of the chiller and the cold generated by the evaporator side, thereby gr...
