Abstract

The invention discloses a solar energy concrete heat storage device for heat energy compensation of heat pumps, which comprises concrete, the concrete is provided with a steel frame, and the steel frame is wound with a heat transfer tube. The steel skeleton of the pipe is placed in the concrete formwork, the concrete is poured, and the pipe joint is reserved in a suitable position outside the concrete. Compared with the traditional hot water heat accumulator, the heat storage capacity of the present invention is greatly increased under the same volume. Concrete, as the heat storage matrix, is made by mixing cement, sand and gravel. These materials are readily available and relatively inexpensive.

Description

technical field [0001] The invention relates to a heat storage device, in particular to a solar concrete heat storage device used for heat energy compensation of a heat pump. Background technique [0002] my country is one of the countries with the most abundant solar energy resources in the world, with the total annual solar radiation exceeding 4200MJ / ㎡ accounting for 76% of the country's land area. Solar energy is a low-grade energy source with low calorific value. According to the principle of graded energy use, it can meet the needs of building and living energy. Therefore, vigorously promoting the application of solar energy in buildings is the most economical and reasonable choice to solve building energy consumption. [0003] Solar energy is a clean, cheap and inexhaustible source of energy, but the biggest obstacle to its utilization is its instability due to the influence of day and night, cloudy, rainy and snowy days. combined use of heat sources. When the solar...
