Cold fans are divided into refrigeration industrial refrigerators and home refrigerators. Industrial refrigerator is generally used in cold storage and cold chain logistics refrigeration environments. Households are also called water -cooled air conditioners. It is a kind of cooling, ventilation, dustproof, and flavor. One body evaporate cooling air replacement unit.

In addition to bringing fresh air and reducing temperature in corporate workshops, public places, and commercial entertainment occasions, there is also an important feature-energy saving and environmental protection! It is a new environmental protection product with a new compressor, no refrigerant, and copper-free pipe. Air conditioning consumes 1/8, which can save more power in various industries.

Cold fans (evaporating air -conditioning) The cooling principle of cooling is: When the fan runs into the cavity, it will generate negative pressure, so that the surface of the dry ball with too many pores and humid curtains on the airflow of the outside machine is forced The temperature of the wet ball, that is, the temperature of the dry ball exported by the cold fan is 5-12 ° C (can reach 15 ° C in the dry hot area), the dry the air, the larger the temperature difference, and the better the cooling effect. Because the air is always introduced from the outdoor, (at this time it is called a positive pressure system), it can keep the indoor air fresh; at the same time, because the machine uses the principle of evaporation to cool down, it has the dual function of cooling and moisturizing (the relative humidity can reach 75%. Left and right), use in textiles, knitting and other workshops, can not only improve cooling and hygroscopic conditions, but also purify the air, reduce the cutting rate of needle in the process of needle textile, and improve the quality of needle textile products. Cold fans (evaporating air -conditioners) are equipped with honeycomb wet curtains using special materials with special materials, which have a large surface area and continuously humidify the wet curtain through the water circulation system; When the fan is running, the negative pressure of the wet curtain refrigerator makes the air flowing through the porous wet wet curtain outside the aircraft into the machine. Due to the evaporation of the water on the wet curtain, it is forced to cool down the air of the wet curtain. At the same time, due to the evaporation of the water flowing through the wet curtain on the wet curtain, the humidity of the air is increased, so the wet curtain cold fan has the dual function of cooling down and humidifying.
