An absorption refrigeration and heat pump system in which a higher temperature subsystem and a lower temperature subsystem are combined with the desorber means of the higher temperature subsystem in heat exchange relationship with the condenser means of the lower temperature subsystem, and in which the evaporators of each subsystems are in heat exchange relationship with either the load in one mode of operation or the heat sink in another mode of operation, and the absorbers and condenser of the lower temperature subsystem are in heat exchange relationship with the heat sink in the first mode of operation and with the load in the other mode of operation. Means are provided to balance the system including a condensate pump between the higher temperature condenser and the higher temperature desorber. Alternate means are provided to improve lower temperature heat pumping by restricting the refrigerant flow through one of the expansion valves and diverting it to the solution pump.

An absorption refrigeration and heating system in connection with a cooling or heating load and a heat sink or source to selectively provide heat to or remove heat from the load, comprising: (a) at least one first subsystem for operation at higher temperature and at least one second subsystem for operation at lower temperature relative to the first subsystem; (b) each subsystem having components of absorber means, desorber means, condenser means, and evaporator means operatively connected together; (c) with the condenser means of the higher temperature subsystem in heat exchange relationship with the desorber means of the lower temperature subsystem; and (d) means to selectively arrange heat exchange relationships between the load and at least two of the component means including the higher temperature absorber, higher temperature evaporator, lower temperature condenser, lower temperature evaporator, and lower temperature absorber, while arranging heat exchange relationships between at least one of the other component means and the heat sink or source.
