Abstract (en)
[origin: EP1717522A1] An air conditioner 100 comprising an outdoor unit 1 having a compressor 11, a direct expansion type indoor unit including indoor heat exchangers 30a, 30b for directly heat-exchanging refrigerant discharged from the compressor 11 with indoor air through liquid pipes 5a, 5b and a gas pipe 5c, a chiller unit 2 for heat-exchanging the refrigerant with water to generate cold water or hot water, and fan coil units 4a, 4b having water heat exchangers 40a, 40b for circulating the cold water or hot water generated in the chiller unit 2 by driving a circulating pump 6 and heat-exchanging the cold water or hot water with indoor air. When the air conditioner falls into an out-of-gas state, the circulating pump 6 is driven, and a motor-driven expansion valve 21 is opened to avoid the out-of-gas state and also prevent freezing of the cold/hot water.
