Modulation absorption refrigerator in plate design

Abstract

An intermittent ammonia-water absorption refrigerator, designed as a stack of vertical plates, having bypass, temperature control, and heat recovery, consisting of two generators, three absorbers, one evaporator, one condenser, two solution-steam pumps controlled by two control valves wherein, for the structuring of the plate stack, in addition to the thin, two-dimensional moulding plates for generators, absorbers, condenser, and evaporator, thick moulding plates having three-dimensional elements for containers, pumps, and distribution channels are used, and the plate stack consists of three face-bonded partial stacks, of which the outer-most contain containers, pumps, and distribution channels, the center stack having the generators, absorbers, condenser, and evaporator is narrower, such that there is a recessed vertical longitudinal channel on the side of the entire plate stack in which the control elements of the machine are installed.
