Document Type and Number:
Japanese Patent JP2021025760
Kind Code:
A
Abstract:
To provide an air-conditioning system which can prevent the intrusion of high-humidity hot air from outside air accompanied by loading and unloading while maintaining a temperature environment of an F-class cargo handling room.SOLUTION: An air-conditioning system 1 has: a first CO2 circulation path 11 in which a first CO2 refrigerant for cooling an F-class cooling room circulates; a second CO2 circulation path 21 in which a second CO2 refrigerant for cooling a C-class cooling room circulates; a desiccant air conditioner 30 having a desiccant rotor 34 for adsorbing the water vapor of treated air which is obtained by treating outside air; an outside air pre-cooling heat exchanger 31B for cooling and dehumidifying the treated air by a second brine which exchanges heat with the second CO2 refrigerant circulating in the second CO2 circulation path; an air cooling coil 90 for cooling the treated air to which the water vapor is absorbed by the desiccant rotor, by a first brine which exchanges heat with the first CO2 refrigerant circulating in the first CO2 circulation path; and a first blowout part 100 for supplying the treated air which is cooled by the air cooling coil into an F-class cargo handling room R1 corresponding to the F-class cooling room.SELECTED DRAWING: Figure 1
