A - or multi-stage absorption-type refrigeration machine (akm) or absorption heat pump (awp) as well as a method for controlling the evaporation output in such a akp / awp

摘要

Multi-stage sorption systems, there are three basic types a, b, c, they are, however, always comprises at least two generators, which in the case of different vapor pressure of the refrigerant and / or different temperature of the sorbent work. In type a are downstream generators in the case of a lower steam pressure by heat of condensation of the previously driven at a higher vapor pressure refrigerant is expelled. In type b, the driving generators which is arranged in each case by the waste heat of an absorber. For this purpose, the sorbent of the absorber to be different to the sorption agent of the waste heat generator driven with the absorber. In type c there is a superposition of type a and b before. By means of the control of the condensate flows between the capacitors, generators and absorbers results in a simple control of the evaporator output.
