When the fan is running, negative pressure is generated in the air conditioning cavity, so that the outdoor air flows into the porous wet curtain surface and enters the cavity, and the moisture on the wet curtain evaporates, taking away a lot of sensible heat, so that the dry-bulb temperature of air passing through the wet curtain is reduced to be close to that of the outdoor air, that is, the dry-bulb temperature at the outlet of the air conditioner is 5- 12℃ lower than the outdoor dry-bulb temperature (up to15 in dry-hot areas)
Principle introduction of evaporative air cooler
It adopts efficient "direct evaporative refrigeration" technology, and its principle is that water absorbs heat energy during evaporation, that is, it absorbs sensible heat of air under the condition of constant enthalpy, so that the temperature of air (dry bulb temperature) is reduced. This phenomenon widely exists in our daily life, for example, when we stand by the sea, we feel particularly cool, when there is water on the skin surface, there will be wind blowing, and so on. This is the result of water absorbing the heat in the air during evaporation, which makes the air temperature drop.
Ventilation principle of evaporative air cooler
In the hot environment in summer, the temperature difference between dry and wet bulb of air is large, and the refrigeration effect is relatively good at this time. After being filtered and cooled by evaporative air conditioner, outdoor fresh air is continuously sent into the room, and the indoor turbid air with peculiar smell, dust and high temperature is discharged out of the room, so that the indoor temperature is lowered, the air oxygen content is increased and the air quality is improved. Therefore, evaporative air conditioning can achieve the dual effects of refrigeration and ventilation, and create a fresh and comfortable living and working environment for you.
Advantages of ventilation and cooling air coolers
When the air cooler is working, the air is always introduced into the room from the outside, so the indoor air can be kept fresh; At the same time, due to the evaporative cooling principle, the machine has dual functions of cooling and humidification. When used in textile and knitting workshops, it can not only improve the cooling and humidification conditions, but also purify the air, reduce the needle consumption and yarn breakage rate in the process of needle-punched spinning, and improve the quality of needle-punched textile products.
When fresh air passes through its wet curtain, the water on the wet curtain directly contacts with the fresh air and evaporates, and the temperature of the air finally drops to near its wet bulb temperature. Therefore, the air cooler has good water absorption, ventilation and filtration functions, and the contact area between water and air is close to 100 times the surface area. Strong texture, water immersion resistance, corrosion resistance and no deformation, and the normal service life can exceed 6 years.
