Control method and control device of heating system, storage medium and heating system

Abstract

The invention provides a control method of a heating system, a control device of the heating system, a computer readable storage medium and the heating system. The control method comprises the following steps: detecting the indoor environment temperature of the heating system in real time; calculating the heating energy requirement according to the indoor environment temperature and determining the heating energy requirement grade according to the heating energy requirement; searching for a working mode corresponding to the heating energy requirement grade according to a pre-stored corresponding relationship between the heating energy requirement grade and the working mode; and adjusting the working parameters of the heating system according to the working mode and the indoor environment temperature, wherein the working mode comprises a heat pump unit and gas stove unit co-opening mode, a gas stove unit single opening mode and a heat pump unit single opening mode. By controlling the working mode and the working parameters of the heating system according to the indoor heating requirements, the problem that the heating output of the gas stove is insufficient when the low-temperatureheating requirement is great, and the gas stove efficiency is not high when the high-temperature heating requirement is small is solved, so that the using comfort of a user is improved and the energysources are saved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a control method for a heating system, a control device for the heating system, a computer-readable storage medium, and a heating system. Background technique [0002] In the related technology, the frequency conversion heat pump + gas furnace control mode is that the heat pump controls the output of the gas furnace, and the energy demand is adjusted by controlling the windshield (air volume) of the gas furnace and the gas intake volume. When the environment is low temperature, the heating capacity cannot quickly meet the energy demand. At this time, a large amount of heating output is achieved by increasing the gas intake volume. At this time, the output of the gas furnace is the largest, and it often cannot meet the requirements of rapid heating, and there are problems of insufficient gas combustion and mismatching heat exchange efficiency. When the ambient tem...

Problems solved by technology

[0002] In the related technology, the frequency conversion heat pump + gas furnace control mode is that the heat pump controls the output of the gas furnace, and the energy demand is adjusted by controlling the windshield (air volume) of the gas furnace and the gas intake volume. When the environment is low temperature, the heating capacity cannot quickly meet the energy demand. At this time, a large amount of heating output is performed by increasing the gas intake volume. At this time, the output of the gas furnace is the largest, and it often cannot meet the requirements of rapid heating, and there are problems of insufficient gas combustion and mismatching heat transfer efficiency.

When the ambient temperature rises, the energy demand decreases, and at this time the gas furnace turns to the low air intake mode, and the efficiency is often not as high as that of the heat pump.
