<p>PROBLEM TO BE SOLVED: To solve the problem of a conventional float switch detecting dehumidification water mechanically that deposit or dust may adhere to the float switch which is thereby locked and dehumidification water can not be detected. SOLUTION: Since abnormality in the water level of dehumidification water can be detected surely without being influenced by deposit or dust when presence of dehumidification water is detected by sensing the temperature thereof through a temperature sensor, operation of an air conditioner can be stopped before the dehumidification water flows over a drain pan and an abnormality can be indicated.</p> |
