<p>An absorption refrigeration and heat pump system in which a higher temperature subsystem and a lowertempera- ture subsystem are combined with the desorber means (50) of the lower temperature subsystem in heat exchange relationship with the condenser means (33) of the higher temperature subsystem, and in which the evaporators (54, 36 or 36') 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 (59, 38) and condenser (51 or 51') 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 (65) between the higher temperature condenser (33) and the higher temperature desorber (30). Alternate means (89,90) are provided to improve lower temperature heat pumping by restricting the refrigerant flow through one of the expansion valves (34), and diverting it to the solution pump (44).</p> |
