Adopting new PWM cold control technology, it can reduce energy consumption by 40% under low temperature conditions. 9. The refrigeration system adopts a set of 2 × 6HP imported French Taikang fully enclosed Compressor composed of a binary cascade Water-Cooled refrigeration system. 10. The air conditioning adopts the forced ventilated equilibrating temperature control method (BTC), and the heater output is controlled by PID automatic operation to achieve dynamic equilibrating. 11. The box is made of SUS304 stainless steel liner and polyurethane foam insulation material, and the observation window is equipped with multi-layer hollow insulation Glass and lighting. 12, with perfect Safety protection measures, including studio overtemperature, refrigerator overpressure/overload/oil pressure, heater short circuit/overload, blast motor overload and system leakage protection.
The Thermal Shock Test Chamber achieves temperature impact through a high-temperature heat storage area, a low-temperature cold storage area, and a product test area. Its refrigeration system uses a binary cascade refrigeration cycle, including a high-temperature refrigeration cycle and a low-temperature refrigeration cycle. Energy is transferred through the evaporative condenser, and the heat energy in the studio is transferred through the two-stage refrigeration system to achieve cooling. The refrigeration Working Principle is based on the reverse carrot cycle. After the refrigerant is adiabatically compressed by the Compressor, it is isothermally exhaled by the condenser, and then adiabatic expansion and cooling by the expansion valve. Finally, it is isothermally absorbed by the evaporator to reduce the temperature of the object to be chilled down, and the cycle repeats to achieve the The temperature control adopts the forced ventilated equilibrating method (BTC). In the case of continuous operation of the refrigeration system, the Control system controls the output of the heater through PID automatic calculation according to the set temperature point, and finally achieves dynamic equilibrating.
