Background
With the development of science and technology and the advancement of humanity, air coolers are widely applied to the fields of life of people and industrial factory buildings. A household air cooler, also called as a water-cooled air conditioner, is an evaporative cooling and ventilating unit which integrates cooling, ventilating, dust prevention and odor removal. The principle is that the temperature of the air is reduced according to the principle that water absorbs heat energy and absorbs sensible heat of the air in the evaporation process. The specific process is as follows: when fresh air passes through the wet curtain, circulating water on the wet curtain is in direct contact with the fresh air to generate heat exchange and filter dust in the air, so that the air is cooled by changing along an isenthalpic line, and the temperature of the air is finally reduced to be close to the wet bulb temperature of the air. Particularly in summer, the difference between the humidity of the dry/wet bulb of the air is large, so that the refrigerating effect is relatively high. Outdoor fresh air is filtered and cooled by the evaporative air cooler and then is continuously sent into a room, and turbid air with smell, dust and high temperature in the room is discharged out of the room, so that the indoor temperature is reduced, and the oxygen content and the quality of the air are relatively stable. Therefore, the evaporative air cooler can achieve the double effects of temperature reduction and ventilation.
However, there are some drawbacks to the evaporative air coolers on the market for domestic use: the limit temperature that the air-cooler was handled is the wet bulb temperature of air-cooler air intake air, and is lower in the great occasion refrigeration efficiency of air humidity, is blockked up the wet curtain by the sand blown by the wind easily and cause the air-cooler to admit air obstructed in the more weather of sand blown by the wind in northwest area, and traditional air-cooler receives a great deal of restriction of condition such as weather and region, has the regional humidity of air conditioner greatly, the cooling is limited, can not satisfy the use scheduling problem of higher occasion.
