FIELD: refrigeration.
SUBSTANCE: invention relates to refrigeration, namely to absorption refrigerators. Absorption refrigeration machine with built-in heat pump unit contains a generator with a first condenser and an absorber unit with a first evaporator. The generator is connected to the absorber by lines of strong and weak solutions passing through the cooling and heating cavities of the first regenerative heat exchanger, respectively. The absorption chiller is equipped with a heat pump unit, a solar heater and a cooling tower, as well as a common storage tank. The heat pump installation includes a second condenser, a compressor, a second evaporator and a second regenerative heat exchanger. The generator of the absorption refrigeration machine and the second condenser of the heat pump unit are made to form a combined heat exchanger.
EFFECT: increasing reliability and efficiency, as well as reducing the metal consumption of an absorption-type installation powered by solar collectors and a heat pump.
