Temperature measurement point

5 power supply

Three-phase five-wire system AC 380V±10%, 50Hz±1 grounding wire, protective grounding resistance is less than 4Ω

The customer at the installation site configures an air or power switch with corresponding capacity for the equipment, and this switch must independently control the use of the equipment


Energy-saving advantage: Different from the cold and heat balance and constant temperature method, it adopts the international advanced hot gas bypass adjustment technology, which can realize the stepless adjustment of the refrigeration output, and the low temperature and constant temperature do not need to turn on the heating system. It can significantly improve the efficiency of the refrigeration system, save energy and reduce consumption.

It mainly has the following advantages:

Prevent short circuit circulation of compressor

Prevent the compressor from working at very low suction pressure

Prevent the evaporator from freezing at low load, minimize system components, and have excellent oil return performance
