3. Resolution: ±0.1 °C;
4. Refrigeration system and compressor: In order to ensure the cooling rate and minimum temperature of the test box, the test box adopts a binary cascade air-cooled refrigeration system consisting of imported German semi-closed compressors. The cascade refrigeration system comprises a high temperature refrigeration cycle and a low temperature refrigeration cycle. The connecting container is an evaporative condenser. The evaporating condenser is also used for energy transfer. The heat energy in the working chamber is transmitted through the two-stage refrigeration system to achieve the enthalpy temperature. the goal of. The design of the refrigeration system uses energy regulation technology, and an effective treatment method can ensure the energy consumption and cooling capacity of the refrigeration system can be effectively adjusted under the normal operation of the refrigeration unit, so that the operation cost of the refrigeration system And the failure rate drops to a more economical state;
5, air conditioning mode: forced ventilation internal balance temperature adjustment method (BTC). The method means that when the refrigeration system is continuously operated, the control system controls the output of the heater according to the result of the PID automatic calculation output according to the set temperature point, and finally achieves a dynamic balance.
