AIR CONDITIONING DEVICE
Document Type and Number:
Japanese Patent JP2021162205
Kind Code:
A
Abstract:
To recover power.SOLUTION: An air conditioning device 1a includes a heat source-side unit 2, multiple use-side units 3a, 3b, 3c, 3d, intermediate units 4a, 4b, 4c, 4d and three or more pieces of communication piping 5, 6, 7. The communication piping 5, 6, 7 connects the heat source-side unit 2 to the intermediate units 4a, 4b, 4c, 4d. The intermediate units 4a, 4b, 4c, 4d include: ejectors 41a, 41b, 41c, 41d and gas-liquid separators 42a, 42b, 42c, 42d. The ejectors 41a, 41b, 41c, 41d increase the pressure of refrigerant. The refrigerant flowing out from the ejectors 41a, 41b, 41c, 41d flows into the gas-liquid separators 42a, 42b, 42c, 42d. The ejectors 41a, 41b, 41c, 41d are prevented from increasing the pressure of the refrigerant that has radiated heat at the use-side units 3a, 3b, 3c, 3d under heating operation.SELECTED DRAWING: Figure 1
