Abstract:
In an absorption system of the type having high and low temperature generators, a condenser associated with the low temperature generator, an absorber, and an evaporator with the sump, all connected to form a closed fluidic system, an improved refrigerant storage system comprising:a refrigerant storage tank located vertically above the condenser and having a storage capacity sufficient to store, during operation in a cooling mode, a quantity of liquid refrigerant which, when released for heating mode operation, is sufficient to reduce the concentration of an absorbent to operate the system efficiently in the heating mode of operation; fluidic connection means between the high-temperature generator, the low-temperature generator, and said refrigerant storage tank during cooling mode operation so as to allow refrigerant vapor to pass from the high temperature generator to said low temperature generator, where it is condensed, and for the resultant liquid refrigerant to pass on to said refrigerant storage tank.
