PURPOSE:To simplify construction work of an air conditioner system, by so constituting that a circulation device and a heat source of a heat source unit is stopped and a switching valve is turned off when pressure in a room and a circulation duct of a heat source side heat exchanger is more than a fixed value. CONSTITUTION:Switching valves 7 and 13 are provided on an indoor side heat exchanger 11 and a heat exchanger 3 of a heat source unit 1 respectively. A pressure sensor 8 is provided downstream the switching valve 7 of the heat exchanger 3. When a temperature more than the fixed value is detected by a remote controller 15 of a radiator 10 and a temperature sensor 14, the switching valve 13 of the radiator 10 is turned off and a fan 12 is suspended. With this, when pressure of a thermal medium being increased becomes more than the fixed one, a circulation pump 2 of the heat source unit 1 is suspended, a switching valve 4a of a gas burner 4 and the switching valve 7 are turned off and the heat source unit 1 is suspended by applying a sensor signal by the pressure sensor 8. With this constitution, it becomes unnecessary to connect between the radiator and the heat source unit by a lead wire and a remote system and construction work can be simplified. |
