Screw Industrial Cooling-Water Machine(-15℃Low Temperature Double-Unit Screw Chiller)
1.Introduction Of Screw Industrial Chiller
Screw industrial chiller is named because its key parts are adopted with screw compressors. The refrigeration capacity of screw industrial chiller is larger than vortex chiller. The machine is widely applied in central air condition system or other large industrial refrigeration. Twin-screw refrigeration compressor is a energy-adjustable fuel injection compressor. Its inspiration, compression and exhaust process, three continuous processes, relies on cyclic volume change when rotating produced by a mutually engaged rotor of yin and yang in the body. In general, the yang rotor is the active rotor, and the yin is the driven rotor.
螺杆式工业冷水机因其关键部件采用螺杆式压缩机而得名，螺杆式冷水机的功率与相比涡旋式的相对较大，主要应用于中央空调系统或大型工业制冷方面。双螺杆制冷压缩机是一种能量可调式喷油压缩机。它的吸气、压缩、排气三个连续过程是靠机体内的一对相互啮合的阴阳转子旋转时产生周期性的容积变化来实现。一般阳转子为主动转子，阴转子为从动转子。
