Patent ID: 7886556

Claim:
An air conditioning system configured to treat a latent heat load and a sensible heat load in a room by performing a vapor compression refrigeration cycle operation, comprising: a plurality of first utilization side refrigerant circuits each having an adsorbent heat exchanger provided with an adsorbent on a surface thereof, configured for alternating between an adsorption process in which moisture in air is adsorbed onto the adsorbent by causing the adsorbent heat exchanger to function as an evaporator that evaporates refrigerant and a regeneration process in which moisture is desorbed from the adsorbent by causing the adsorbent heat exchanger to function as a condenser that condenses the refrigerant, and connected in parallel with one another; and a plurality of second utilization side refrigerant circuits each having an air heat exchanger, configured for exchanging heat between refrigerant and air, and connected in parallel with one another, the first utilization side refrigerant circuits being configured to supply a room with air that passed through the adsorbent heat exchanger, and the second utilization side refrigerant circuits being configured to supply a room with air that passed through the air heat exchangers a heat source side refrigerant circuit including a compression mechanism and a heat source side heat exchanger, with the compression mechanism and the heat source side heat exchanger of the heat source side refrigerant circuit being arranged in the air conditioning system such that only the compression mechanism of the compression mechanism and the heat source side heat exchanger is used in common with the first and second utilization side refrigerant circuits, the heat source side heat exchanger operates as a condenser of the refrigerant discharged from the compression mechanism when the air heat exchangers operate as evaporators of the refrigerant, and the heat source side heat exchanger operates as an evaporator of the refrigerant condensed in the air heat exchanger when the air heat exchangers operate as condensers of the refrigerant discharged from the compression mechanism, the first utilization side refrigerant circuits being connected to a discharge gas connection pipe connected to a discharge side of the compression mechanism, and being connected to an inlet gas connection pipe connected to an inlet side of the compression mechanism.
