Building energy-saving solar heat storage water supply system

Abstract

The invention discloses a building energy-saving solar heat storage water supply system which comprises a water storage tank, evacuated collector tubes, a reflecting plate, a heat preservation water tank and a supporting frame. The reflecting plate is located on the sides, obliquely facing downwards, of the multiple sets of evacuated collector tubes; one end of the heat preservation water tank communicates with the interior of the water storage tank through a connecting pipe; each evacuated collector tube comprises a glass outer tube and a glass inner tube; a vacuum cavity is formed by each glass outer tube and the corresponding glass inner tube, and arc-shaped reflecting plates and air suction films are arranged in the vacuum cavities; an air suction film is attached to the inner wall of each glass outer tube; lenses are annularly arranged on the inner walls of the glass outer tubes; and the two groups of arc-shaped reflecting plates are symmetrically arranged in each vacuum cavity and attached to the inner wall of the corresponding glass outer tube, and the outer arc directions of the arc-shaped reflecting plates correspond to the outer wall of the corresponding glass inner tube. According to the building energy-saving solar heat storage water supply system provided by the invention, the heat efficiency of a solar water heater is improved, and the heat preservation performance is improved.

Description

technical field [0001] The invention belongs to the field of energy saving, and in particular relates to a building energy-saving solar heat storage water supply system. Background technique [0002] With the continuous improvement of energy-saving design awareness, solar buildings play an important role in building a resource-saving society, and it has gradually become an important way for building energy-saving design. my country's building energy consumption has accounted for more than one-third of the country's total energy consumption, which has seriously restricted the development of the national economy. Building energy conservation is of great significance, of which cooking and hot water account for a considerable proportion. Facing the energy crisis and environmental problems, the country attaches great importance to the utilization of renewable energy. In the Renewable Energy Law, the state encourages units and individuals to install and use solar water heating sy...

Problems solved by technology

Most of the existing solar structures are integrated solar structures, where multiple vacuum heat collecting tubes are directly inserted into the heat preservation water tank. The effect is low; for example, the patent with application number CN201910907605.1 discloses a solar heat storage device, which directly inserts a plurality of vacuum heat collecting tubes into the heat preservation water tank, and sets the heat storage rods to be rod-shaped and hollow inside , one end is the heat dissipation section, and the other end is the heat storage section. The heat storage material is sealed inside the heat storage section to realize the heat storage of the solar system. However, the device has too many slots, the heat preservation water tank is too long, and the heat dissipation area ratio is large. question
