option for waste heat

Will draw the waste heat from the evaporator 3 to simplify things - diagram 1 (2).

 Liquefied gases collected with the liquid working substance coming out of the evaporator 3 and the heat exchange with the compressed refrigerant gas in the heat exchanger 25. One such option unit will be less effective than when part of the  waste heat returns to the evaporator as a chart 1.

 On the one hand the system for redistributing heat (cooler) must overcome a large temperature difference in this option. We also need to increase the circulation of liquid working substance in the cycle, which is another loss of useful power.
