摘要：
Kobe Steel has developed a new inverter driven semi-hermetic ammonia screw refrigerator. By adopting a new control method for linking the compressor speed to the compressor suction pressure, a 40% greater cooling capacity can be generated at an evaporating temperature of -40°C, and 35% energy saving can be achieved at a 50% partial load compared to that of our conventional refrigerator. In addition, the semi-hermetic structure prevents ammonia from leaking from the mechanical seal of the compressor. This machine can be used for a wide range of evaporating temperatures from -30°C to -60°C and for applications such as freezing food, process cooling, etc.
