Document Type and Number:
Japanese Patent JP2021076339
Kind Code:
A
Abstract:
To prevent a refrigerant from being released to a ceiling space from a refrigerant circuit of an air conditioning device in which refrigerant leakage occurs, to prevent the refrigerant from entering a housing of the other air conditioning device through the ceiling space.SOLUTION: An air conditioning system 10 includes first to third air conditioning devices, and a management unit 90 for managing them. The first to third air conditioning devices respectively have a refrigerant circuit, and one housing 40. The refrigerant circuit has a compressor, a radiator, an expansion valve, and an evaporator. A flammable refrigerant is circulated in the refrigerant circuit. The housing to accommodate the refrigerant circuit is disposed in a ceiling space CS1. The ceiling space in which the housings of the first to third air conditioning devices are disposed, is a continued one space. The management unit keeps all of the first to third air conditioning devices in an operation stop state or an operation inhibition state when refrigerant leakage is detected in any of the air conditioning devices.SELECTED DRAWING: Figure 1
