Abstract: PURPOSE: To prevent freezing of water dewed over the surface of an evaporator, by fixing a receptacle for receiving water dewed over the surface of an evaporator to a lower portion of the evaporator, and providing in said receptacle a thermo-sensor for detecting the dew point from the water temperature.  
     CONSTITUTION: A receptacle 20 for receiving water dewed over the surface of an evaporator 3 is attached to a lower portion of the evaporator 3, and a thermo- sensor 26 for detecting the dew point from the water temperature is provided in a water reserving section 21 formed at the bottom of the receptacle 20. Here, by utilizing the fact that, when freezing of water is caused, the temperature of water is lowered continuously to about 5°C, and after the temperature drop is once stopped at about 5°C, the temperature is again lowered continuously to about 0°C, a signal is produced from the thermosensor 26 for stopping operation of the apparatus when the temperature of water in the water reserving section 21 is about 5W0°C. With such an arrangement, detection of temperature by the thermo-sensor 26 can be rendered reliable, and operation of the apparatus can be stopped before the evaporator 3 and a drain pan cause a large amount of freezing.
