Document Type and Number:
Japanese Patent JP2019148370
Kind Code:
A
Abstract:
To provide a heat pump type heating dryer capable of supplying a use side with air having passed through a condenser and subsequently heated and dried, even when a defrosting operation is being carried out.SOLUTION: A heat pump type heating dryer 100 comprises: a coolant circuit 1 that comprises a heat-source side heat exchanger 3, a compressor 4, a use side heat exchanger 5 and an expansion mechanism 6 and can perform a defrosting operation for circulating a coolant R while repeating compression and evaporation and allowing the use side heat exchanger 5 to function as an evaporator; an air duct 11 connected to the use side heat exchanger 5, wherethrough outside air exchanging heat with the use side heat exchanger 5 flows; and an adsorption heat exchanger disposed downstream of the use side heat exchanger 5 to generate heat by adsorbing moisture and to release moisture by absorbing heat, in the air duct 11.SELECTED DRAWING: Figure 1
