Shanghai TianFeng industrial Co., LTD
Screw Air-Cool Chiller(Room Temperature Double-Unit Screw Chiller 2)
The aluminum sheet spacing of screw air-cool chiller is designed accurately, so it can reduce frosting probability maximally. The machine can make comprehensive analysis and judgments fully combining with time, temperature and pressure, and really defrost according to the need. The machine defrosts thoroughly every time and can extend defrost interval.
Screw air-cool chiller 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.
螺杆式风冷冷水机精确设计铝片片距,最大减少结霜几率。充分结合时间、温度和压力进行综合分析判断,真正实现按需除霜,且每次除霜彻底,延长除霜间隔。
螺杆式风冷冷水机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。
