Pre-water cycle heat exchange solar water heating engineering system

Abstract

The invention provides a front water circulation heat exchange solar water heating engineering system which comprises a water consumption pond, a coarse filter screen, a circulating pump, a heat absorbing plate, a water distributor, a water collecting tank and a fine filter. The water consumption pond is connected with the coarse filter screen by a first pipeline, and the coarse filter screen is further connected with the circulating pump by a second pipeline; the circulating pump is connected with the water distributor by a third pipeline, and the water distributor is positioned above a high-end water inlet of the heat absorbing plate; the heat absorbing plate is positioned at a high location with sufficient illumination; the water collecting tank is positioned below a low-end water outlet of the heat absorbing plate and is further connected with the fine filter by a fourth pipeline, and the fine filter is further connected with the water consumption pond by a fifth pipeline. The front water circulation heat exchange solar water heating engineering system has the advantages that the integral system is simple in structure and high in heat efficiency; water is low in circulating resistance, high in circulating strength and low in required water pump lift and motor power; the front water circulation heat exchange solar water heating engineering system is low in engineering manufacturing cost and system running cost and can be easily accepted.

Description

technical field [0001] The invention relates to a pre-water cycle heat exchange solar hot water engineering system. Background technique [0002] Swimming pools, aquatic products overwintering and other places consume a lot of water. When heating, solar water heating projects with a large lighting area need to be used, but there is another very important feature, that is, the requirements for water temperature are relatively low. Just below 36°C. Many existing engineering designs have neglected the utilization of this feature, resulting in a great waste of technology and high project cost. There is another kind of plastic heating pipe solar water heating project. Although it takes advantage of this feature, omits the insulation covering, simplifies the structure, and reduces the cost, it has long hot water pipelines, a large number of connections, and large circulation resistance. , It needs to be matched with a high circulating water pump head and motor power, which great...
