AIR-CONDITIONING SYSTEM

Abstract: the air-conditioning system sends, to a living room, air-conditioning room air in an air-conditioning room independent of the living room. in the air-conditioning room, an air conditioner is installed. a refrigerant concentration sensor detects a concentration of a refrigerant contained in the air-conditioning room air. a state changer switches between a first state where the air-conditioning room air is sent to the living room and a second state where air coming in and out of the air-conditioning room is less than the air-conditioning room air in the first state. a leakage determination unit determines whether or not the refrigerant is leaking by acquiring the refrigerant concentration detected by the refrigerant concentration sensor in the second state.
