<p><P>PROBLEM TO BE SOLVED: To provide a heat pump device which has a simple constitution and can execute reliable defrosting. <P>SOLUTION: The heat pump device includes a determination means S100, S101 for determining the presence or absence of the necessity of defrosting in a heat exchanger 114, and a frost formation detection temperature sensor 133 for detecting a temperature to detect the frosting condition of a surface of the heat exchanger 114. When it is determined that the defrosting is necessary from a determination result by the determination means S100, S101, a control means 140 operates a defrosting means 120 to begin a defrosting operation, and executes the defrosting operation corresponding to a frosting condition based on the temperature obtained by the frost formation detection temperature sensor 133. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
