Veranda wall backrest direct inserted type unpowered solar energy water-heating system

Abstract

The invention discloses a balcony wall backrest straight-inserted unpowered solar water heating system which comprises a heat collecting device, a water tank, a water pipe, a thermostatic mixing valve and a nozzle, wherein the heat collecting device and the water tank are arranged back to back in the balcony wall, one end far away from the water tank of a heat pipe is higher than the other end inserted into the water tank, the heat pipe is arranged in the heat collecting device according to the level inclination no more than 5 degrees, the end inserted into the water tank of the heat pipe is backwards bent into an angle of 90 degrees and inserted into one end of the water tank, the lower end of the water tank is provided with a tap water inlet pipe, and the upper end of the water tank is provided with a water heating outlet pipe. The water tank and the heat collecting device are arranged back to back, which results in that the occupancy space is saved, and the water can be circulated by the pressure of the tap water, which saves the electricity; the invention has the advantages of the small volume, the convenient use, the simple installation, the low cost, the small heat loss, furthest utilizing the solar energy, the high water heating efficiency, the simple operation and the maintenance-free character; property managers and developers avoid maintenance troubles. The invention is suitable for any residential building, particularly for high-rise residential buildings.

Description

1. Technical field [0001] The invention belongs to a solar water heating system. 2. Background technology [0002] Solar water heating systems currently on the market include household in-line, central heating and balcony wall systems. The traditional direct plug-in water heaters for households are usually a few glass tubes, which are placed on the roof of the building with a large round water tank. The installation is fixed, and its installation also seriously affects the appearance of the building. It cannot be applied to high-rise buildings. Under the background of requiring the integration of solar energy and buildings, this product cannot escape the fate of being eliminated. The collectors of the central heating system are placed on the roof of the building, which solves the appearance problem to a certain extent, but the roof area of ​​high-rise residential buildings is often not enough for the use of solar water heaters for the entire building. Moreover, this system ...

Problems solved by technology

The traditional direct plug-in water heaters for households are usually a few glass tubes, which are placed on the roof of the building with a large round water tank. The installation is fixed, and its installation also seriously affects the appearance of the building. It cannot be applied to high-rise buildings. Under the background of requiring the integration of solar energy and buildings, this product cannot escape the fate of being eliminated.

The collectors of the central heating system are placed on the roof of the building, which solves the appearance problem to a certain extent, but the roof area of ​​high-rise residential buildings is often not enough for the use of solar water heaters for the entire building. Moreover, this system Larger, the subsequent heat loss of pipelines and equipment is also greater, and a large amount of electric energy is required to maintain water temperature and water circulation. At the same time, daily maintenance by the property department is required. The price of hot water produced in this way is relatively high, which is not easy for ordinary people to accept

Traditional balcony-type solar water heaters are often installed separately from the heat collector and water tank, and a circulating water pump is needed in the middle, and the water tank needs to occupy space between the bathroom or balcony. The heat collector is often hung on the outer wall of the balcony, which affects the effect of the outer wall
