[Feature]

High Reliability

Scroll compressor has 60% fewer internal parts than reciprocating compressor. The scroll compressor is constructed to prevent liquid refrigerant and impurities from entering the compressor.

Equipped with a microcomputer control device to protect the compressor from failure. The torque change of the scroll compressor is 1/3 of the reciprocating compressor.

High Efficiency

The scroll compressor is rotary volume design, with small clearance volume, small friction loss and high operating efficiency. The unit adopts a combination of multiple compressors, which has high efficiency in part load operation.

Compressor

The refrigerant circuit and control circuit are completely independent ,can be used alternately according to loading condition, which can effectively extend the service life. It has the advantages of high efficiency, low energy consumption, low noise, low vibration, wear resistance and high reliability.

Condenser

Shell and tube condenser, the heat exchange tubes are outer finned copper tube, the cover plates at both ends are removable, can be removed to clean the copper tub. The condenser shell is equipped with a fusible plug, effectively ensure the safe operation of the system. The condenser has passed the national pressure vessel inspection.

Evaporator

Shell and tube type evaporator adopts inner fin copper tube, and is equipped with refrigerant shunting device, which can evenly distribute the refrigerant to each heat exchange tube, which improves the heat exchange efficiency. For multi-compressor chiller, each compressor is equipped with an evaporator and a condenser, the three constitute an independent refrigeration system. Due to structural reasons, the water paths of the two evaporators are often connected, but the refrigeration circuits are independent.  The exterior of the evaporator is affixed with thermal insulation material to avoid the loss of cooling capacity.

Thermal expansion valve

The world-renowned brand Emerson thermal expansion valve is used for higher control accuracy, wider adjustment range and faster response.  Under any working conditions, the heat exchange area of the evaporator can be fully utilized, the heat exchange is more sufficient, and the efficiency is higher, which can ensure the reliability of the refrigeration system.
