♦ High Reliability
O Screw compressors have few parts, no wearing parts, stable and reliable operation, long life.
O The screw compressor uses a new generation of high-efficiency 5:6 patented asymmetric tooth shape design to improve work efficiency.
O Screw type compressor with volumetric design .small clearance volume, small friction losses, and high operating efficiency.
♦ Compressor
O The refrigerant circuit and control circuit are completely independent ,can be used alternately according to loading condition, which can effectively extend the service life of the unit. 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 tube. 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
O 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
O 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.
Control System
◊ Start-Stop protection, control compressor starting frequency
O Equivalent setting of compressor start-stop times and running time
O Touch Screen Controller
O Can add remote monitoring, Provide RS485 communication interface.
O Power-off memory, historical fault query function
O Overload protection, phase sequence protection, anti-frozen protection, high and low pressure protection, exhaust temperature protection and other protections.
O Inlet and outlet water temperature control
O Monitoring of in and out water flow
O Reserved joint control contact of chilled water pump, cooling water pump, cooling tower.
