荷兰格拉索公司(Grasso-Stacon BV)推荐一种新设计的旋转容积式压缩机,该公司根据法国人Bernard Zimmern提出的方案,设计成一种具有许多优点的装置。这种单螺杆装置是为工业作为通常的单级压缩机或者制冷、空调和热泵装置中的低压升压级用而研制的,用氨或F_(22)工作,据称还可以采用其他冷剂,现在的试验只限于氨和F_(22)。该机是通过挠性联轴节用一台三相、二极、
Grasso-Stacon BV of Holland recommended a newly designed rotary displacement compressor designed according to the proposal of the Frenchman Bernard Zimmern as a device with many advantages. This single-screw unit was developed for industrial use as a low-pressure boost stage in conventional single-stage compressors or refrigeration, air conditioning and heat pump units operating with ammonia or F 22 and purportedly that other refrigerants , The current test is limited to ammonia and F_ (22). This machine is through a flexible coupling with a three-phase, two poles,
