  • Patent number: 6305182
    Abstract: A refrigerant control apparatus for use in an absorption heating and cooling system of the type which uses a refrigerant and an absorbent, and which includes a generator, a condenser, an absorber and an evaporator having an evaporator sump. The control apparatus includes a reservoir, disposed in condensate collecting relationship to the condenser, and in refrigerant draining relationship to the evaporator. The reservoir has a storage capacity sufficient to store, during operation in the cooling mode, a quantity of refrigerant large enough to reduce the steady state concentration of the operating solution from a first, relatively high concentration used in the cooling mode to a second, relatively low concentration used the heating mode, and includes an overflow structure that allows refrigerant to overflow into the evaporator when the reservoir is filled.
