Abstract
The internal heat exchangeris provided which exchanges heat between the refrigerant of low pressure and the refrigerant of high pressure, and the pre-load adjusting mechanism of the expansion valveis abolished. Due to the above structure, the refrigerant flowing into the expansion valveis cooled in the internal heat exchanger, and enthalpy of the refrigerant flowing into the evaporatoris reduced. On the contrary, the refrigerant sucked into the compressoris heated. Accordingly, a difference in enthalpy between the refrigerant at the inlet and the refrigerant at the outlet of the evaporatorcan be made large, and the heat absorbing capacity of the evaporatorcan be enhanced, and further it becomes possible to give the degree of superheat to the refrigerant sucked into the compressor. Therefore, even if the pre-load adjusting mechanism is abolished, the vapor-compression-type refrigerating machine can be stably operated.
