摘要： Heat exchange is performed between a discharge side refrigerant and a suction side refrigerant also at the time of a heating operation. By this, a liquid phase refrigerant containing lubricating oil in the suction side refrigerant is heated by the discharge side refrigerant, and the liquid phase refrigerant is vaporized also at the time of the heating operation, so that the amount of the liquid phase refrigerant sucked into a compressor is decreased. Accordingly, the increase of compression work of the compressor is prevented, and an opening area of an oil return hole can be expanded to such a degree that an optimum amount of lubricating oil is attained at the time of the heating operation.

摘要： 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. A valve controllably establishes a fluidic path between the reservoir and the evaporator sump when the system is switched from operation in its cooling mode to operation in its heating mode.
