Design of a Cooling Rate for a Dual Compressor Low-temperature Constant Temperature Bath
In order to meet the requirements of temperature field in metrology verification or calibration,aiming at the problems of long cooling time and low working efficiency of existing standard thermostatic tank,a double com-pressor cryostatic tank with fast cooling rate and temperature control range(-80～0)℃ was designed.At the same time,according to the requirements of JJF 1030-2023"Technical Performance Test Specification for thermostatic bath for Temperature Calibration",the time required for the thermostatic bath to reach the preset temperature value during operation and the temperature uniformity and fluctuation after the preset temperature were verified.
