Document Type and Number:
Japanese Patent JP6694582
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To execute a desired tapping temperature constant control according to a water temperature and a water level in a water supply tank in a heat pump-type feedwater heating system.SOLUTION: A heat pump 4 circulates a refrigerant to a compressor 12, a condenser 13, an expansion valve 14 and an evaporator 15 successively annularly connected, and pumps up heat from a heat source water passing through the evaporator 15, to heat the water passing through the condenser 13. Water can be supplied to a water supply tank 3 from a water supply passage 8 through the condenser 13, and also water can be supplied thereto from a makeup water passage 9 without passing through the condenser 13. A feedwater flow rate is adjusted to keep an outlet-side water temperature of the condenser 13 at a target temperature during the water supply to the water supply tank 3 through the water supply passage 8. The target temperature can be changed on the basis of water temperature and/or water level in the water supply tank 3.SELECTED DRAWING: Figure 1
