Abstract

The method involves holding the temperature of the coolant liquid upstream of the injection valve (A) constant in order to achieve stable conditions in the regulation and refrigeration circuit and hence highly efficient evaporation. Stable conditions in the regulation and refrigeration circuit are achieved by holding the suction steam temperature upstream of the compressor (B) constant.
