description The invention relates to a water breaking protector which uses water as heat exchange medium, used in air conditioner, while present technique uses a controller to check water switch and control compressor, with inaccurate water station detection. And in invention, two middle relays via a wire terminal form a control circuit, to connect an external controller and a water switch, and link with an open contactor of an alternative-current contactor of a water pump, therefore, the invention checks the water states before starts water pump and after powers the machine and the water states after starts the water pump to convert the water state into inactive signal to be transmitted to the controller of the air conditioner, to control the air conditioner. The invention can avoid running air conditioner when water is not fed.
