Abstract

PURPOSE:To perform an optimum defrosting apparatus regardless of a surrounding temperature of the outdoor apparatus by providing a logic circuit to input a temperature signal of the 1st and the 2nd temperature detectors and control the temperature signal of the 1st temperature detector in accordance with the temperature signal from the 2nd temperature detector. CONSTITUTION:The 1st temperature detector 8 to detect a piping temperature of the outdoor apparatus for a heat pump, the 2nd temperature detector 9 to detect a temperature around the outdoor apparatus and a logic circuit 11 to input a temperature signal S7 of the 1st temperature detector 8 and a temperature signal S8 of the 2nd temperature detector 9 are provided. When the temperature signal S8 of the 2nd temperature detector 9 indicates more than the defrosting prohibition temperature K3 deg.C, the logic circuit 11 controls the whole not to output the temperature signal S7 of the 1st temperature detector 8. Therefore, when the temperature around the outdoor apparatus is over the defrosting prohibition temperature K3 deg.C, the piping temperature of the outdoor apparatus is not detected. The useless defrosting operation by an erroneous detection in a high outdoor temperature can be eliminated.
