摘要

All multi-stage absorption machines include at least one high pressure generator in which refrigerant is expelled from the sorbent at the highest temperature level encountered in the engine, and at least one medium pressure generator in which refrigerant is also expelled from the sorbent, the medium pressure generator being driven by the heat of condensation of the expelled in the high pressure generator Refrigerant vapor is heated. Here, two principal circuit variants A and B are presented, both based on the fact that additional drive heat is coupled together with the heat of condensation from the refrigerant vapor in the medium pressure generator without changes on the side of the heat exchanger must be made on the solution side, or that the heat exchange surface of the medium pressure generator the drive side must be divided in a fixed ratio. DOLLAR A Variant A couples heat at a lower temperature level via one or more steam generators into the medium pressure generator. In this case, the heating steam additionally generated via external heat sources is combined with the refrigerant vapor coming from the high-pressure compressor and condensed on the condenser side of the medium-pressure generator. DOLLAR A Variant B couples all heat in the medium pressure generator by means of a common heat carrier intermediate circuit, including the refrigerant vapor from the high-pressure generator in an additional high-pressure condenser ...
