Unpowered self-heat-exchange structure and method

Abstract

The invention discloses an unpowered self-heat-exchange structure and method.The unpowered self-heat-exchange structure is breathable, diathermanous and anti-seepage buried holes, the breathable, diathermanous and anti-seepage buried holes are formed in the bottom of an underground reservoir, breathable and anti-seepage sand is laid in the breathable, diathermanous and anti-seepage buried holes, the upper surface of the breathable and anti-seepage sand makes contact with a water body in the reservoir, and the lower surface of the breathable and anti-seepage sand makes contact with the water body in the reservoir. The lower surface is in contact with the soil under the reservoir, and the water body and the soil exchange heat through the breathable anti-seepage sand. According to the unpowered self-heat-exchange method, heat exchange is carried out between a water body in the underground reservoir and soil below the reservoir through breathable anti-seepage sand arranged in breathable, diathermic and anti-seepage buried holes below the reservoir. Aiming at the limitation of natural energy utilization in building heat supply in cold and water-deficient areas such as the north, the invention provides a multipurpose rainwater energy pool, the energy pool combines sponge city construction and natural energy development, collects, purifies and stores rainwater sewage, stores water and performs energy exchange with stratum soil, indirectly utilizes soil heat energy, and saves energy. And heat energy is stored in the water tank.

Description

technical field [0001] The invention relates to the technical field of energy saving, and more specifically relates to a non-powered self-heat exchange structure and method. Background technique [0002] Building energy consumption is an important part of the world's energy consumption. According to the "Research Report on China's Building Energy Consumption (2017)", the energy consumed by Chinese housing buildings in the entire life cycle accounts for 40% to 50% of the country's total energy consumption. In 2017, my country's total building energy consumption was 899 million tons of standard coal, accounting for 21.11% of the country's total energy consumption, and the energy consumption of public buildings accounted for 38.33% of the total building energy consumption. The energy consumption index is high and the total amount is large. Compared with traditional energy sources such as coal and petroleum, heat pump technology is a renewable energy utilization technology, whic...

Problems solved by technology

Among them, water source is the simplest and cheapest heat source. However, similar to Beijing and other northern regions of China, the development and utilization of groundwater resources is strictly prohibited, and water source heat pump technology is difficult to adopt, which restricts the application of water source heat pump technology in northern regions.
