Dual-purpose furnace working system

Abstract

The invention relates to a dual-purpose furnace working system which comprises a combustion heat-exchanging device, a fuel gas pipeline, a heating pipeline, a domestic water pipeline, a heat exchangerand an expansion water tank. The expansion water tank is provided with a first cavity, a second cavity and a third cavity. The first cavity communicates with the heating pipeline, the second cavity communicates with the domestic water pipeline, and the third cavity communicates with a balance air source. The dual-purpose furnace system can provide hot water sources for domestic water and heatingwater simultaneously, in the heating process, the domestic water is supplied as a priority, and energy is effectively utilized; two cavities of the expansion water tank are simultaneously connected toa heating waterway and a domestic waterway of a dual-purpose furnace in series, the expansion and shrinking quantity of circulating water in a heating loop and the expansion and shrinking quantity ofwater in the domestic waterway can be contained and supplemented, and pressure fluctuation of the heating loop and the domestic water can further be relieved; and stability of the water flow rate iskept, and the use comfort of the bathroom domestic water is improved while the heating function is ensured.

Description

technical field [0001] The invention relates to a dual-purpose furnace working system, in particular to a dual-purpose furnace working system capable of simultaneously providing heating water and domestic hot water. Background technique [0002] For winter heating systems in small and medium-sized supermarkets, hotels, homes, schools, etc., current heating devices generally have disadvantages such as large footprint, limited geographical area, large investment, serious waste of power resources, and slow heat production. The use of ordinary floor heating, because the return water is mostly lost through the sewer or returned to the well, resulting in a serious waste of groundwater resources, the installation of outdoor main pipelines requires labor and material investment, and the investment in deep-water wells is huge. Now the country has put an end to deep-water wells. If the electric geothermal film is used, the power consumption is too large; the power consumption of ordin...

AI Technical Summary

Problems solved by technology

Although the above-mentioned system can provide heating and hot water for domestic use, when the pipeline is filled with water and kept heating, the hot water will exert pressure on the pipeline. Part of the water in the road is released to reduce the pressure in the pipeline. When water is needed, there will be problems of water pressure fluctuations and unstable water flow; if a water pressure stabilization device is installed in the pipeline, it will increase the heating system. occupying an area, and cannot take into account both heating and domestic hot water
