Description

Device and method for integrating solar energy adsorption, heating, cooling, supply and water purification

technical field

The invention belongs to the technical field of solar heat utilization and air-conditioning refrigeration, and in particular relates to a device and method for integrating solar energy adsorption, heat supply, cooling supply, cooling water and water purification.

Background technique

With the reduction of traditional energy sources, renewable energy sources such as solar energy, wind energy, biomass energy, and tidal energy are ushering in a period of development. Solar energy has developed rapidly due to its unique advantages. Solar energy is an inexhaustible and Inexhaustible renewable clean energy is recognized as the safest, most ideal and greenest energy for human beings in the future. Solar energy has the advantages of large total amount and low cost. Solar refrigeration is an important aspect of solar energy application. Fluorocarbon as a traditional The refrigerant in the refrigeration system releases a large amount of chlorofluorocarbon gas into the atmosphere. Solar-powered refrigeration systems generally use non-fluorocarbon substances as refrigerants, which will not damage the ozone layer and will not pollute the environment. In our country, the temperature in most areas in summer is too high, and people will use a lot of refrigeration equipment such as air conditioners and refrigerators, which will lead to insufficient electricity during peak electricity consumption in summer. Solar refrigeration technology can partially or completely replace traditional vapor compression refrigerators or indoor air conditioners, thereby reducing the load on the grid during peak periods. However, the current solar refrigeration system has the disadvantages of low refrigeration performance coefficient and energy utilization rate, and high initial investment costs.

At present, the total amount of water resources on the earth is 1.5×10 ¹⁸ m ³ , 97.3% of which are in the ocean, and only 2.7% of the fresh water resources, and a large part of the 2.7% of the fresh water are icebergs, which are distributed at the two poles of the earth Only 0.7% of fresh water is distributed in rivers, rivers, and lakes in China's ice and snow areas, which are used for human drinking and crop irrigation, which is far from meeting the needs. Internationally, there is a saying that "the struggle for coal in the 19th century, the struggle for oil in the 20th century, and the struggle for water in the 21st century". In order to solve the problem of lack of fresh water resources, scientists from all over the world have turned their attention to the field of seawater desalination. However, the traditional seawater desalination technology has high investment and excessive energy consumption, which restricts the rapid development of solar seawater desalination technology. Solar seawater desalination mainly There are two methods: use the thermal energy generated by the sun to drive the seawater to undergo phase change and separate, and condense the separated water vapor to produce fresh water; use the direct current electric field generated by solar energy to make the ions in the seawater migrate directionally, and achieve this through the ion exchange membrane. Separation of solute and solvent to achieve seawater desalination. Both adsorption refrigeration and seawater desalination require solar energy to provide energy. The adsorption refrigeration system achieves refrigeration through the adsorption and desorption of refrigerants (water, methanol, etc.) by adsorbents (silica gel, activated carbon, etc.), so consider solar adsorption refrigeration and seawater Combining desalination, using silica gel or activated carbon as the adsorbent and seawater as the refrigerant, it can not only achieve refrigeration, but also desalinize seawater to solve the problem of shortage of fresh water resources.

After a patent search, it was found that the existing solar heat pump air-conditioning system is mainly used for cooling and heating, and there is no device for cooling, heating, water purification using the solar adsorption refrigeration system. Patent CN204555309A, titled as a composite adsorbent solar heat pump water heater, provides a patent that not only utilizes the heat energy of solar energy itself, but also uses the desorption and adsorption heat of the composite adsorbent to heat hot water, which improves the efficiency of hot water production and reduces the electric energy. consumption, but the system can only be used to provide hot water, the function is single, and the investment is not directly proportional to the output. Patent CN104501453A, titled multi-energy heating, cooling and hot water supply integrated system device, the device provides a method of heating, cooling and hot water supply integration combined with solar energy and biomass boilers, but the device provides heating in winter Sometimes the solar adsorption refrigeration system cannot be used, resulting in a waste of resources; using solar energy to heat cold water (0°C) in winter requires a lot of heat, and it is difficult to use solar energy to heat cold water to 50°C in areas where solar energy is insufficient.

To sum up, the existing solar adsorption refrigeration system has the problems of single function, low refrigeration efficiency, high investment cost of seawater desalination technology, and excessive energy consumption.
