Title:
EXHAUST HEAT UTILIZATION SYSTEM
Document Type and Number:
Japanese Patent JP2023091222
Kind Code:
A
Abstract:
To enable a reheating device and an air conditioner to use their exhaust heat mutually and thus further save energy while simplifying a configuration and reducing cost.SOLUTION: An exhaust heat utilization system includes: a reheating device 3 having a hot water circulation heating circuit 31 for circulating and heating hot water in a bathtub 2; a heat pump type air conditioner 4 having a refrigerant circuit 43 for circulating a refrigerant; a heat exchange section 5 enabling heat exchange between the hot water in the hot water circulation heating circuit 31 and the refrigerant in the refrigerant circuit 43; and an operation control section 72. When the air conditioner 4 is in a cooling mode, the operation control section 72 can execute a hot water heating operation for circulating hot water in the hot water circulation heating circuit 31 to supply hot water to the heat exchange section 5 and heating hot water by using heat of the refrigerant in the refrigerant circuit 43. When the air conditioner is in a heating mode, the operation control section 72 can execute a refrigerant heating operation for circulating hot water in the hot water circulation heating circuit 31 to supply hot water to the heat exchange section 5 and heating the refrigerant in the refrigerant circuit 43 by using heat of the hot water.SELECTED DRAWING: Figure 1
