Title:
STORAGE TYPE HOT WATER SUPPLYING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/145238
Kind Code:
A1
Abstract:
This storage type hot water supplying system 1 comprises: a heat exchanger 38 that exchanges heat between a heating medium and water; a hot water storage tank 8; a first pump 11 that circulates the heating medium in a first circuit connecting the heat exchanger 38 to a heat pump device 3; a second pump 12 that circulates the water in a second circuit connecting the heat exchanger 38 to the hot water storage tank 8; and a control device 50 that controls the first pump and the second pump. During heat storing operation in which hot water accumulates in the hot water storage tank 8, the first pump 11 is controlled so that the temperature of the heating medium heated by the heat pump device 3 is equal to a target temperature, and the second pump 12 is controlled so that the water temperature difference that is the difference between the temperature of the hot water heated by the heat exchanger 38 and the temperature of the water before being heated by the heat exchanger 38 is equal to the heating medium temperature difference that is the difference between the temperature of the heating medium heated by the heat pump device 3 and the temperature of the heating medium before being heated by the heat pump device 3.
