Wall-mounted gas boiler, hot water supply system and control method

Abstract

The invention relates to a wall-mounted gas boiler comprising a heat exchanger, a first water inlet pipe, a first water outlet pipe, a second water inlet pipe and a second water outlet pipe. The heat exchanger comprises a first passage and a second passage which are used for carrying out heat exchange with smoke generated by gas combustion, and both the first passage and the second passage can allow a fluid to pass through and do not intercommunicate; the first water inlet pipe and the first water outlet pipe respectively communicate with two ends of the first passage to form a first heat supply unit; the second water inlet pipe and the second water outlet pipe respectively communicate with two ends of the second passage to form a second heat supply unit; and the first heat supply unit and the second heat supply unit can independently or simultaneously output a heat source. By using the wall-mounted gas boiler, hot water for heating and daily use can be simultaneously supplied, and the problems of insufficient heat exchange amount in a heating space and temperature reduction caused by overhigh water consumption of hot water for daily use are avoided.

Description

technical field [0001] The invention relates to the technical field of wall-hung boilers, in particular to a gas-fired wall-hung boiler, a hot water supply system and a control method. Background technique [0002] Conventional gas wall-hung boilers use gas as the main energy source, and usually have the dual function of providing hot water for heating and domestic hot water. Usually, gas wall-hung boilers can switch working modes according to seasonal changes. For example, in summer mode, the heating function of the gas wall-hung boiler is turned off, and it is only used to provide domestic hot water for users; Domestic water needs. [0003] However, in the winter mode, the currently commonly used gas wall-hung boilers are all set to give priority to domestic hot water, that is, when users need domestic water, the gas wall-hung boilers are used to provide heat for domestic hot water first, and stop heating water for heating. When the user turns on the domestic water func...

AI Technical Summary

Problems solved by technology

When the user turns on the domestic water function for too long or too frequently, the gas wall-hung boiler cannot take care of both heating and domestic water needs, which will easily lead to insufficient indoor heating heat and a drop in room temperature, bringing users an uncomfortable experience
