Cold room evaporator cooling methords

The working theory of the refrigeration fan 1 The working theory of cold room evaporator (also known as evaporative air cooler) is mainly based on evaporative cooling technology, which absorbs heat through the evaporation of water, so as to achieve the effect of cooling. Here look at how it works: Evaporative cooling process When the fan is running, it creates a negative pressure in the cavity that forces air outside the machine to flow through the porous and moist pad surface. The moisture on the wet curtain absorbs the heat in the air during the evaporation process, so that the dry-bulb temperature of the curtain air drops to the wet-bulb temperature close to the wet-bulb temperature of the air outside the machine, so as to achieve the cooling effect. Cooling effect The dry-bulb temperature at the outlet of the cooler is usually 5-12°C cooler than the outdoor dry-bulb temperature, and can even reach 15°C in hot and dry areas. The hotter and drier the air, the greater the temperature difference, and the better the cooling effect. Air circulation and humidification The air cooler always brings in air from the outside to maintain the freshness of the indoor air. At the same time, the evaporative cooling process also has a humidification function, and the relative humidity can reach about 75%, which is especially suitable for textile, knitting and other workshops, which can not only improve the working environment, but also improve product quality. Energy saving and environmental protection Compared to traditional air conditioning systems, air coolers do not require refrigerants or power-intensive compressors, making them more energy efficient, less expensive to operate, and less environmentally friendly. Application Scenarios Evaporator are widely used in industrial, commercial and household fields, especially in high-temperature environments, such as factory floors, food processing, textiles and printing industries, which can effectively reduce ambient temperature, improve air quality.
