- Model : -15℃ Low Temperature Screw Chiller Single-Unit 2
- Brand :
- Product ID :
- Product Type : Industrial products series
- Product Content :
Low temperature screw chiller takes a semi-enclosed twin-screw compressor as the core, refrigerant as the carrier, air or water as cold source when refrigerating , and releases heat at the load side to cold source through refrigerating cycle in order to heat the main side of the central air-conditioning unit of the load.
Detailed
-15℃ Low Temperature Screw Chiller Single-Unit 2
低温螺杆冷水机是以半封闭双螺杆压缩机为核心，以制冷剂为载体，制冷时以空气或水为冷源，将负载侧的热量通过制冷循环释放到冷源，从而对负载侧进行制冷降温；风冷型机组制热时以空气为热源，通过制冷循环将热源侧的热量提取后到负载侧进行释放，从而对负载的中央空调设备主机侧进行加热升温。
上海田枫的低温螺杆冷水机制冷效率高，产生同样的制冷量所消耗的电能要更少，运行时噪音也相对更小。
