Abstract

A refrigeration arrangement comprising a compressor, a pair of heat exchangers, an expansion valve, accumulator means, and means for driving refrigerant from the discharge side of the compressor to the suction side thereof through one of said exchangers of heat, making it function as a condenser, of said expansion valve, of the other heat exchanger, making it function as an evaporator, and of said accumulator means, characterized by a refrigerant charge in said arrangement, which is so much greater than that necessary to meet the requirements of said heat exchangers, that there is always a quantity of refrigerant liquid within said accumulator means; a heat exchange coil connected in front of said expansion valve and arranged in heat transfer relation with respect to said accumulator means in such a way that it causes the cooling liquid therein to evaporate with heat from the high coolant liquid. pressure circulating through said coil, and valve control means for adjusting said expansion valve to continuously supercharge said other heat exchanger, for all the loads imposed on it during the normal operation of said system, with liquid refrigerant at flow to which the liquid is evaporated within said other heat exchanger and within said accumulator means, thereby causing non-evaporated liquid to circulate continuously from said other heat exchanger to said accumulator means, at substantially the flow rate to which it is evaporated the liquid inside said accumulator means.
