Embodiment Construction

[0008] Such as figure 1 As shown, this system includes collectors (1), water tanks (including (7), (2), (3)), pumping stations (including (6), (8), (11), (5), (4), (10), (12)), controller, sensor, auxiliary heating device (9), preheating system (13) and pipeline (14).

[0009] The flat plate used in the flat plate collector is all-aluminum cladding, and the whole plate core design and processing technology with 12 runners perforated and 360° full cladding heat transfer. It is superior to the original ordinary flat design structure and technology (7-8 runner linear welding, strip assembly).

[0010] Solar heat collection: The hot water tank (including heat collection, heat storage, and constant temperature) is designed as a pressure-bearing coiled tube. The flat plate collector and its built-in copper coil are filled with a heat-conducting working fluid (energy conversion antifreeze). Solar heat circulation runs indirect heat exchange to heat the water in the water tank and store ...

Abstract

The invention discloses a flat-plate-type solar hot-water concentrated-supply system which is composed of heat collectors, a water tank set, pump stations, a controller, a sensor, auxiliary heating devices, a preheating system and a pipe. The system is characterized in that the novel efficient flat-plate heat collectors are adopted as the heat collectors and are arranged in an array mode; the water tank set comprises a heat storage water tank, a preheating water tank and a constant temperature water tank, and all the water tanks are designed in a pressure-bearing mode; a flow-guide-type positive displacement heat exchanger is adopted as a heat exchanger, gas water heaters are adopted as the auxiliary heating devices, and a ground source heat pump is adopted as the preheating system. Through the design, the whole system has the advantages of being high in heat absorption and heat transfer efficiency, constant in temperature and pressure, free of water leakage and capable of supplying hot water safely and reliably all day long.

Description

Technical field [0001] The invention relates to a solar centralized hot water supply system, in particular to a flat-plate solar centralized hot water supply system. Background technique [0002] In recent years, China’s solar thermal utilization technology has developed rapidly, and domestic solar water heaters have been commercialized and widely used in urban and rural areas. With the advancement of urbanization, the integration of solar energy and building technology has improved, in addition to civilian residences, high-end hotels More and more public buildings, such as hotels, schools, hospitals, swimming pools, etc., are beginning to adopt solar centralized water heating systems. However, due to the diversity of product structures and materials on the market, different structural designs or component selections will have different use effects For example, heat collectors mainly include all-glass evacuated tube collectors, flat plate collectors, and heat pipe collectors; hea...
