A thermal chemical adsorption heat storage system for building heating

Abstract

The invention relates to a thermo-chemical adsorption heat storage system for building heating. The thermo-chemical adsorption heat storage system comprises an air flow channel, a cold air fan (1) andan adsorption bed (4) internally provided with adsorbents with water absorption and heat storage capacity, wherein the cold air fan (1) and the adsorption bed (4) are arranged in the air flow channelin sequence along the flow direction of cold air; a humidifier (2) and a heater (3) are further arranged between the cold air fan (1) and the adsorption bed (4); and a fresh air inlet which is provided with a fresh air fan (5) is further formed in the position, at the rear end of the adsorption bed (4), of the air flow channel. Compared with the prior art, the heating system is clean, environmentally friendly and high in working efficiency; an energy storage function is achieved so that off-peak electric power, or low-grade waste heat or solar energy can be stored and released when a user hasa heating requirement, and energy consumption of building heating can be effectively reduced; the humidifying and heating functions are achieved, and thus indoor heat comfort can be effectively improved; and in addition, the system is convenient to operate, safe, reliable and low in machining and operation cost.

Description

technical field [0001] The invention relates to the technical field of building heating, in particular to a thermochemical adsorption heat storage system for building heating. Background technique [0002] The efficient and clean utilization of energy directly affects the sustainable development of society and the environment. With the development of the economy and the increase of population, residents have higher and higher requirements for the comfort of buildings, and energy consumption has also increased. Statistics show that my country's building energy consumption accounts for about 30% of the total energy consumption of the society, of which energy consumption for cooling, heating and domestic hot water accounts for 20% to 30%. The heating energy consumption in the northern region accounts for about 40% of the total energy consumption of buildings. The current building heating methods used in my country mainly use fuel combustion or electric energy to provide heat: ...

AI Technical Summary

Problems solved by technology

Fuels such as boilers are still dominated by non-renewable energy - coal, and its combustion will emit greenhouse gases such as nitrogen dioxide and sulfur dioxide and PM2.5 particles, causing great harm to the environment and people's health

Air source heat pump is a high-efficiency heating system that has received a lot of attention in recent years, but when the outdoor environment is lower than 5°C, frost will occur, resulting in a sharp drop in heating performance

However, electric wire heaters and electric oil heaters are only suitable for local heating, with low efficiency and poor thermal comfort

Generally speaking, the current winter heating methods still have problems such as high energy consumption, environmental pollution and low efficiency, and there is still a lot of room for improvement in building heating technology
