Problems solved by technology
[0004] Among the above two switching methods, manual valve switching is inconvenient to use. For example, when taking a bath, the hot water is insufficient, and other personnel are needed to help; the electric three-way valve automatically switches, which can achieve continuous hot water supply, but cannot realize instant opening Instant heat, unable to meet the stability of uninterrupted hot water supply, unable to meet the user's requirements for comfort

The invention discloses a household air source heat pump hot water system assisted by a fuel gas wall-hanging furnace and a control method thereof. The hot water system comprises an air source heat pump water heater, a fuel gas wall-hanging furnace, a linkage controller, a water flow sensor, a manual three-way valve, a three-way electric valve, a first manual valve, a second manual valve, a waterreturn circulating pump, a first temperature sensor and a second temperature sensor; and the first temperature sensor is installed on a second water return pipeline, and the second temperature sensoris arranged on a water tank outlet part of the air source heat pump water heater. The control method comprises control steps for the three-way electric valve and the control steps for the water returncirculating pump. The household air source heat pump hot water system assisted by the fuel gas wall-hanging furnace and the control method thereof have the function of instant heating, and have the functions of being stable in hot water supply, energy-saving, intelligent, long in service lives of devices, and high in hot water supply reliability.
Description
technical field [0001] The invention relates to a domestic air source heat pump hot water system, in particular to a domestic air source heat pump hot water system with auxiliary water supply from a gas wall-hung boiler and a control method thereof. Background technique [0002] As the air source heat pump water heating system is included in the building renewable energy water heating system, more and more residential buildings choose to use the household air source heat pump water heating system when configuring the renewable energy water heating system; especially in the south of the Yangtze River In the area, the air source heat pump hot water system has a good energy-saving effect. At the same time, floor hot water heating is gradually promoted in cold winter and hot summer areas, and the heating method mainly uses gas wall-hung boilers. In order to better ensure the domestic hot water supply, the gas wall-hung boiler is used as a supplementary heat source for the air so...
