    • PURPOSE: A heat compressor of multi-stage type is provided to have semi-permanent lifespan and to improve compressing efficiency by directly heating and compressing refrigerant by using electric energy not to require lubrication. CONSTITUTION: A refrigerant is flowed into a suction aperture(12) of a heat pump(10) through an evaporator and electricity(22) is fed to a heater(21) to heat the refrigerant. The refrigerant in a compressor(11) is expanded for increasing the pressure of the compressor. A nonreturn valve(32) in the second compressor is opened for closing the nonreturn valve of the first compressor to short a switch(23) connected to electricity. Thus, the refrigerant discharged through a vent port(13) of the compressor flows to the compressor of a second heat pump. Then, the switch of the electricity is grounded to the heater installed in the compressor and supply heat source to the compressor. The compressed refrigerant in the second compressor flows to the third compressor for compressing the refrigerant at a desired pressure at the last outlet.
    • 目的:提供多级式热压缩机具有半永久寿命,并通过使用不需要润滑的电能直接加热和压缩制冷剂来提高压缩效率。 构成:制冷剂通过蒸发器流入热泵(10)的吸入孔(12),并且电(22)被供给到加热器(21)以加热制冷剂。 压缩机(11)中的制冷剂被膨胀以增加压缩机的压力。 打开第二压缩机中的止回阀(32),用于关闭第一压缩机的止回阀以缩短与电连接的开关(23)。 因此,通过压缩机的通气口(13)排出的制冷剂流到第二热泵的压缩机。 然后,将电力的开关接地到安装在压缩机中的加热器,并将热源供给压缩机。 第二压缩机中的压缩制冷剂流到第三压缩机,以在最后一个出口处以期望的压力压缩制冷剂。
