<P>PROBLEM TO BE SOLVED: To provide a heat storage defrosting device which does not require excessive power for defrosting and permits effective defrosting in a short time without impairing the original function of a heat pump cycle. <P>SOLUTION: In the heat storage defrosting device, an endothermic heat radiation heat exchanger 125 is arranged on the downstream side so as to stand in a line in the flow direction of the air for heat exchange with respect to a heat sink heat exchanger 113, coolant is set to flow through a bypass flow path 114 by means of a flow path switching means 15, thereby, heat generated from at least one side of a travelling motor and equipment 112 is stored onto the coolant, and when performing defrosting at the time of heating operation, the coolant to which the heat is stored is set to pass through the heat sink heat exchanger 113 by means of the flow path switching means 15, thereby, a heat supply means 125a is actuated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
