Shanghai TianFeng industrial Co., LTD
Screw Water-Cool Chiller Room Temperature Double-Unit 1
Screw water-cool chiller produced by Shanghai Tianfeng is widely used in central air conditioning, industrial cooling and other various fields. When it is used in industrial cooling, low temperature water produced by chillers can be directly sent into the equipment and containers that need cooling. But in order to control accurate and stable water temperature, the output water from chillers is sent into the equipment and containers that need cooling after sending to buffer pool.
Screw water-cool chiller units produced by Shanghai Tianfeng has high cooling efficiency. Producing the same amount of refrigeration consumes less electricity. Run-time noise is also relatively small.
上海田枫螺杆式水冷式冷水机组广泛应用于中央空调、工业冷却等各个领域。作为工业冷却使用时,冷水机组产生的低温水可以直接送到需要冷却的设备、容器内,但往往为了控制精确稳定的水温,冷水机组出水是送到缓冲水池后再进入需要冷却的设备或容器内。
上海田枫螺杆式水冷式冷水机组制冷效率高,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。
