Description
Technical Field
The invention relates to the technical field of solar building heat collection, in particular to an all-weather solar heat supply system and method based on open adsorption heat storage.
Background
Most of the energy sources used in the current buildings come from fossil fuels, so that the energy safety of China is greatly influenced, and the environment is negatively influenced. In order to reduce excessive consumption of non-renewable energy sources in buildings, researchers have conducted various researches, and combining solar energy technology with buildings will be an important solution way for developing renewable energy sources on a large scale and reducing the consumption proportion of traditional fossil energy sources in the buildings.
Terlambertian walls are an efficient way to harness solar energy in construction. However, the terlambertian wall has some defects, which limit the popularization and the use thereof. During night or long cloudy days, a large amount of heat is transferred from the interior of the room to the outside through the terlambertian wall, resulting in heat loss of the room and increased energy consumption, which is particularly significant in areas with cold climates.
In cold winter, the temperature of the enclosure structure is obviously lower than the indoor temperature, and the enclosure structure is distributed in a gradient manner from indoor to outdoor. Especially glass is close to outdoor temperature due to poor heat insulation performance. However, one typically ignores the non-uniform distribution of the indoor thermal environment in winter, focusing only on using a heat source above the indoor desired temperature to maintain the indoor desired temperature. In practice, the building can be insulated by water lower than room temperature, and indoor heat dissipation can be effectively reduced. If the soil heat source and the natural water source in the natural environment are fully utilized, the heat transferred from the indoor to the outside can be completely reduced, so that the requirement of high-grade heat supply is reduced, and the heat supply energy consumption is further reduced.
The invention patent with the publication number of CN112178962A discloses a system and a method comprising a photovoltaic photo-thermal phase-change water tank, a super-lambertian wall and plants, wherein the system comprises the photovoltaic photo-thermal phase-change water tank, the super-lambertian wall, the plants and an electricity storage system; the system can realize multiple functions of power generation, hot water production, passive refrigeration, passive heating, air purification and the like. In a non-heating season, the photovoltaic photo-thermal phase-change water tank and plants respectively reduce the temperature of a building wall by heat storage and transpiration, and a solar chimney is formed by the photovoltaic photo-thermal phase-change water tank and a terlander wall while hot water is obtained, so that a passive refrigerating function of the building is achieved; in a heating season, the photovoltaic photo-thermal phase-change water tank is combined with the super lambertian wall, so that the heat is stored while the passive heating of the building is realized, and plants absorb CO2 to release O2 through photosynthesis and are coupled with the passive heating process to adjust the indoor air quality. Besides seasonal realization of water heating, passive refrigeration, passive heating and indoor air quality adjustment, the system can realize annual power supply.
In the invention, water and phase change materials are used as heat storage media to store solar energy which is surplus in daytime, the heat storage energy density is low, and the volume of a water tank is large; the water pump is required to drive to complete the effective heat storage and release process, and the power consumption of the system operation is high.
The invention patent with publication number of CN112082274A discloses a composite type super-lambertian wall body capable of effectively reducing heat loss, and the super-lambertian wall body is combined with a water wall. The invention can utilize low grade energy sources such as soil heat source, natural water source and the like at night, and can circulate low-temperature water in the water wall so as to reduce heat loss of the building. The invention has simple structure and low cost, can effectively reduce the heat dissipation in the room and ensures the heat comfort in the room.
The invention adopts water as a heat storage medium to store solar energy which is surplus in daytime, the heat storage energy density is low, and all-weather building heat supply can not be satisfied under the heat storage volume meeting the design requirement; the water pump is required to drive to complete the effective heat storage and release process, and the power consumption of the system operation is high.
