Description

Solar air water taking device with complementary circulating adsorption refrigeration

Technical Field

The utility model relates to an air water intake device especially relates to a complementary solar energy air water intake device of circulation adsorption refrigeration.

Background

Water resources are the basis for human survival and all production activities, however, the availability of fresh water resources to humans is very limited. The per-capita fresh water resource in China is less than 1/3 in the per-capita level in the world, and the fresh water resource is very uneven in space and time distribution. In the mountains, gobi, deserts, islands, grasslands and other areas, the fresh water resources are more deficient due to the serious shortage of rainfall and underground water supply. Therefore, it is an emerging research direction in recent years to try to extract water from the air by developing new technologies to obtain fresh water resources.

At present, the international air water taking technology shows the production trend, and large-scale air water taking equipment used in areas with high air humidity is developed in the countries of the United states, Germany, Israel and the like. For example, the company Eole Water in france improves a wind power generation turbine to realize both wind power generation and air Water taking. However, such devices have the disadvantages of being clumsy, bulky, and not portable. The existing air water taking technology mainly comprises a mechanical compression method, an adsorption and desorption method, a semiconductor refrigeration method and the like. The mechanical compression method is that the dew point temperature of the compressed wet air is increased by an air compressor, and the water vapor in the compressed air is condensed into liquid water. However, this method is too high in energy consumption and cannot be popularized and used.

The adsorption and desorption method is to utilize solid or liquid adsorbent to adsorb moisture in air, desorb the moisture by heating the adsorbent, realize that water vapor is enriched into high-humidity air, and condense the air into liquid water after cooling. The water taking efficiency of the method depends on the water absorption performance and the air humidity condition of the adsorbent, and some adsorbents are easy to pollute the environment. CN201210397948.6 provides a portable travelling bag capable of supplying water, which utilizes lithium chloride composite adsorbent with high adsorption performance to improve the water intake rate of solar adsorption type air water intake and ensure that desert travelers can obtain the water amount of normal water in desert. CN01113489.5, CN200410053390.5 and CNZL02261055.3 are main bodies of a solar heat collector made of an adsorption bed, an adsorbent placed in the solar heat collector is heated by sunlight, and a water vapor working medium is liquefied into liquid water in a condenser after being desorbed from the adsorbent and flows into a water storage tank. At night, the adsorbent in the heat collector is naturally cooled along with the atmospheric environment and begins to adsorb water vapor in the air. The technical scheme combining the solar heating and the adsorption and desorption method has the advantages of simple structure, low manufacturing cost and the like, but the water taking efficiency is very low.

The semiconductor refrigeration method mainly utilizes the Peltier effect of semiconductors, and realizes cold end refrigeration effect under the condition of electrification by connecting a P-type semiconductor element and an N-type semiconductor element to form a thermocouple. The semiconductor refrigeration technology has the advantages of light weight, environmental protection and portability, and has the defects of large energy consumption of the heating end and low water taking efficiency. CN2567274Y provides a solar energy semiconductor refrigeration dewfall method air water intaking ware, adopt the thermoelectricity to condense the air, when the air temperature drops to below its corresponding dew point temperature, the vapor in the air condenses into liquid water droplet to carry out abundant heat transfer with the air that gets into the water intaking ware with the lower air of temperature that goes out from the condensation chamber, thereby make the air obtain the precooling before getting into the cold drawing, also retrieved cold volume simultaneously, but the heat that thermoelectric chip hot junction produced is effectively not in time discharged, leads to the not high refrigeration efficiency of thermoelectric chip, the water intaking rate of water intaking ware unit energy is low.

The prior art has the defects that the large-scale air water collector has large volume and is difficult to carry, and cannot be popularized in regions with deficient fresh water resources, such as mountains, deserts, islands and the like; the small-sized air water taking device has one or more defects of high energy consumption, difficult popularization, low water taking efficiency, environmental pollution and the like.
