Balcony wall-mounted solar water heater

Abstract

The invention relates to a balcony wall-mounted solar water heater which comprises a water tank and a heat collector, wherein the water tank and the heat collector are communicated to form a heat exchange circulation loop through a low-temperature circulating pipe and a high-temperature circulating pipe; a water feeding branch pipe, a water use branch pipe, a shielding pump, a pressure switch anda temperature difference electromagnetic valve are arranged on the low-temperature circulating pipe; and water tank temperature sensors are arranged in the heat collector and the water tank. In the balcony wall-mounted solar water heater provided by the invention, the shielding pump and the pressure switch are matched to realize the automatic pressurization of the water in the water use branch pipe; the solar water heater does not need to adopt the pressure bearing water tank and can guarantee that users can normally use the water; the manufacturing difficulty and cost are greatly reduced; and the potential safety hazards of the pressure bearing water tank are avoided. In the balcony wall-mounted solar water heater provided by the invention, an automatic control box controls the opening and closing of the shielding pump through the temperature difference of the heat collector and the water tank; and the forced circulation is realized and the heat exchange of the heat collector and thewater tank is realized by combining the natural circulation of the temperature difference and the forced circulation of the shielding pump, thereby greatly enhancing the flow velocity of the water, improving the heat exchange effect and realizing the remote installation of a solar heat collector and a heat-insulation water tank.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a balcony wall-mounted solar water heater. Background technique [0002] With the advent of split solar water heaters, more and more people choose them as household water heaters. It changes the integrated type of traditional solar water heater into a split type, that is, the water storage tank and the heat collector are separated from each other, so that the water storage tank can be placed indoors, and the heat collector can be flexibly installed on the balcony wall or under the window of the outer wall, which solves the problem of urban The shortcomings of ordinary solar water heaters are inconvenient to install on high floors, so they are also called balcony wall-mounted solar water heaters. [0003] The current balcony wall-mounted solar water heater has a big problem, that is, because it cannot use the height difference to discharge water, it must use a pressure-bearing water tank,...

AI Technical Summary

Problems solved by technology

The disadvantages of natural circulation heat exchange are: slow heat circulation speed, poor heating effect, and it is not easy to realize long-distance installation of water tank and heat collector
