【発明の名称】潜熱回収方式の給湯装置における制御装置
Document Type and Number:
Japanese Patent JP2734100
Kind Code:
B2
Abstract:
PURPOSE:To feed necessary for water at all times by making the judgement of a hot water feed interval when both of the temperature and amount of hot water in a hot water storage tank do not meet predetermined conditions while making the judgement of a hot water feed stopping interval when they meet such predetermined conditions, and forming a hot water feed route in the former case while releasing the hot water feed route in the latter case to allow it to be shifted to a heat dissipation interval. CONSTITUTION:When hot water (49 deg.C) is initially supplied from a hot water heat exchanger 11 to a hot water storage tank 25, a level switch 27 produces no level detection signal because the hot water storage tank 25 is in an empty state, and accordingly, a third solenoid valve 29 is opened and a fourth solenoid valve 32 is closed. When an amount of hot water in the storage tank 25 reaches a second level HH in due course, the level switch 27 produces the level detection signal to excite each of coils 29a, 32a. This results in closing the third solenoid valve 29 and opening the fourth solenoid valve 32 to stop water feed from a water feed pipe 12 to the hot water heat exchanger 11. In this instance, a hot water pump 30 receives the level detection signal in addition to a temperature detection signal, and its operation is thereby stopped. As a result, although the opening of the fourth solenoid valve is disregarded, a first solenoid valve 17 is closed and a second solenoid valve 18 is opened by the signal of stopping the pumping operation.
