Solar wall-hung boiler hot water heating system

Abstract

The invention discloses a solar wall-hung boiler hot water heating system and relates to the technical field of the solar energy. A hot water outlet is connected with the upper part of a double-coil-pipe water storage tank through a watering valve; a cold water outlet is connected with the bottom of the double-coil-pipe water storage tank; a liquid-level sensor of the double-coil-pipe water storage tank is connected with a solar central controller; an upper heat exchanging coil pipe in the double-coil-pipe water storage tank and a heating radiating system form a loop; a lower heat exchanging coil pipe and a solar thermal collector, an outflow plate and an inflow plate form a loop; an expansion water tank is further arranged between the lower heat exchanging coil pipe and the inflow plate;the solar thermal collector is connected with the solar central controller through an external hot water sensor; and the double-coil-pipe water storage tank is connected with the solar central controller through an internal hot water sensor. According to the solar wall-hung boiler hot water heating system, system circulating heat exchanging is controlled between the double-coil-pipe water storagetank and the solar thermal collector through the inflow plate and the outflow plate; the utilization ratio of the solar energy is high; and heat exchanging is fast.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a hot water heating system for a solar wall-hung boiler. Background technique [0002] Solar energy is a renewable energy source, and solar water heaters are devices that convert solar energy into thermal energy. They have been rapidly developed and promoted in my country, but their working conditions are restricted by natural conditions. Although there are also solar water heaters with auxiliary electric heating function, they consume more power, and the electric heating device is placed in water for a long time, which may easily cause safety hazards such as electric leakage. The wall-mounted boiler water heater uses electricity (gas) as energy source, so it can work without restriction and can supply hot water continuously, but electricity (gas) is a non-renewable resource and the cost is high. At present, the heating devices for solar wall-hung boilers on the market have...

Problems solved by technology

Although there are solar water heaters with auxiliary electric heating function, they consume more power, and the electric heating device is placed in water for a long time, which may easily cause safety hazards such as electric leakage

The wall-mounted boiler water heater uses electricity (gas) as the energy source, the work is not limited, and hot water can be continuously supplied, but electricity (gas) is a non-renewable resource and the cost is high

At present, the heating devices of solar wall-hung boilers in the market have unsatisfactory combined effects, and there are still problems such as low efficiency and waste of resources.
