Embodiment Construction

[0011] Such as figure 1 As shown, the system includes a heat collector (1), a hot water storage tank (7), a constant temperature water tank (12), a pumping station (including (2), (6), (9), (10), (11) , (13)), controller, heat exchanger (5), auxiliary heating device (14) and pipeline (8).

[0012] The system consists of three circulation subsystems. The first subsystem is the circulation between the solar energy and the plate heat exchanger, that is, when the temperature of the collector - the outlet temperature of the plate exchange medium T1-T2≥8c° (adjustable), the heat collection is started Circulation pump P1, when T1-T2≤3c° (adjustable), the collector circulation pump P1 stops; Subsystem 2 is the circulation between the plate replacement and the hot water storage tank, that is, when the plate is replaced, the water temperature - the hot water storage tank When the internal temperature T3-T4≥8c° (adjustable), start the heat collecting circulating pump P2, and when T3-T4≤...

Abstract

The invention discloses a heat tube type solar central hot water supply system. The heat tube type solar central hot water supply system consists of a heat collector, a hot water storage tank, a constant-temperature water tank, a pump station, a controller, a heat exchanger, a gas-fired boiler and a pipeline and is characterized in that the heat collector is a heat tube type heat collector in-line-arranged array, the hot water storage tank and the constant-temperature water tank are pressure-bearing water tanks, and the heat exchanger is a plate heat exchanger. By means of the design and model selection, the heat tube type solar central hot water supply system has the advantages of being high in heat transfer efficiency, constant in temperature and pressure and free of tube explosion and water leakage, saves energy and is efficient and safe.

Description

technical field [0001] The invention relates to a solar centralized hot water supply system, in particular to a heat pipe type solar centralized hot water supply system. Background technique [0002] In recent years, my country's solar thermal utilization technology has developed rapidly, and domestic solar water heaters have been commercialized and popularized in urban and rural areas; More and more public buildings such as hotels, schools, hospitals, and swimming pools have begun to use solar centralized water heating systems. However, due to the variety of product structures and material selections on the market, different structural designs or component selections will have different use effects. For example, there are three main types of collectors: all-glass vacuum tube collectors, flat plate collectors and heat pipe collectors; heat exchangers include tube heat exchangers, air heat exchangers, plate heat There are many kinds of heaters and so on; the hot water storage t...
