ABSTRACT:
A cooling system including a compression refrigeration unit and an absorption refrigeration unit, with the compression refrigeration unit including a compressor having a capacity control mechanism; a condenser for cooling and condensing a compressed refrigerant gas through a heat exchange between the refrigerant gas and a cooling medium circulated through the condenser; and an evaporator into which the condensed refrigerant is introduced through an expansion means so as to be evaporated and cool a medium by the latent heat derived from evaporation. The absorption refrigeration unit includes a generator having a capacity control mechanism for heating a solution to generate a vapor of a refrigerant and a strong solution; a condenser in which the vapor of refrigerant generated in the generator is cooled and condensed an evaporator in which the refrigerant in the condenser is evaporated and cools a medium to be cooled by latent heat from the evaporation; an absorber in which the vapor of refrigerant is absorbed by the strong solution generated and forms a weak solution; and a pump for feeding the weak solution to the generator. The compression refrigeration unit and the absorption refrigeration unit are connected so that at least the medium to be cooled and the cooling medium first flows into the compression refrigeration unit and then into the absorption refrigeration unit.
