The present invention provides an air conditioner which stops operation at the occasion when the water supply is stopped in operation or no water is supplied in compressor starting for preventing freezing. Refrigerant tubes (10,11) for the air conditioner are connected with an outdoor unit (1) and an indoor unit (23). The outdoor unit (1) is provided with a plate type heat exchanger (4), a compressor (2) and an outdoor expansion valve (5). The plate type heat exchanger (4) is provided with a plate for flowing of water and a plate for flowing of refrigerant. The indoor unit (23) is provided with an indoor heat exchanger (25), wherein: a temperature sensor (9) for measuring the temperatures of the plate for flowing and water and the plate for flowing of refrigerant is provided on a side surface of the plate type heat exchanger. At the occasion that the value of the temperature sensor is below a preset value, the operation of the compressor is stopped.
