Abstract A refrigerating machine which is a combination of a compression type refrigerating apparatus and an absorption type refrigerating apparatus. The compression type refrigerating apparatus comprises a compressor, a condenser, a throttle valve and an evaporator connected in series so as to form a first closed loop. The absorption type refrigerating apparatus comprises a generator, a condenser, an evaporator and an absorber connected in series so as to form a second closed loop. The generator of the absorption apparatus is arranged as a heat exchanger for continuous transfer of heat from the cooling agent of the first loop, on the pressure side of the compressor, to the mixture of cooling agent and absorbent in the generator of the second loop. The evaporator of the absorption apparatus is connected as a heat exchanger for continuous cooling of the cooling agent of the first loop after the condenser of the compression apparatus on the input side of the throttle valve. By combining the generator and the compressor into a unit a decrease in temperature can be obtained in the outlet valve of the compressor.
