The cooling fan (evaporative air conditioner) cooling principle is: when the fan is running, it enters the cavity to generate negative pressure, so that the air outside the machine is excessive.

The wet curtain surface of the air cooler hole forcibly cools the dry bulb temperature of the curtain air to a temperature close to the wet bulb temperature of the outside air, that is, the dry bulb temperature of the outlet of the air cooler is 5-12 ° C lower than the outdoor dry bulb temperature (dry heat area) Up to 15 ° C), the hotter the air, the greater the temperature difference, the better the cooling effect.

  

Since the air is always introduced into the room from outside (this 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 and cooling, it has the dual functions of cooling and humidifying (relative temperature can reach 75%). Left and right), used in textile, knitting and other workshops, not only can improve the temperature and temperature increase conditions, but also purify the air, reduce the needle breakage rate in the needle spinning process, and improve the quality of the needle textile products.

  

The air cooler (evaporative air conditioner) is equipped with a honeycomb wet curtain using special materials, which has a large surface area and continuously humidifies the wet curtain through the water circulation system; the high-efficiency low-noise energy-saving fan is installed in the wet curtain air cooler. When the fan is running, the negative pressure of the wet curtain air cooler causes the air outside the machine to flow through the porous wet curtain into the machine, and the heat of the water on the wet curtain absorbs heat, forcing the air passing through the wet curtain to cool down. At the same time, since the water on the wet curtain evaporates toward the air flowing through the wet curtain, the humidity of the air is increased, so the wet curtain air cooler has the dual functions of cooling and humidifying.

1. When the temperature is high and the workshop needs to cool down, turn on the air switch and press the “cooling” button directly. It will start for one minute (the pump will feed the wet curtain), which is normal. After one minute, the unit will enter normal operation. When the temperature is low (winter), you can directly press the “send air” button to send fresh air into the room for ventilation.

                                                                                     

2, industrial cooling fan shutdown: press the "stop" button, the machine immediately stops (if not used for a long time, turn off the air switching power supply).

  

3. The external double-layer filter of the industrial chiller machine should be cleaned once a month to two months depending on the external environment, so as to avoid the blockage of the incoming air and affect the life of the motor.

  

4, industrial cooling fan "clean" button is used to clean the chassis and replace fresh water. When the new machine is used, it may have a glue smell and a fishy smell. It should be cleaned once a day from the previous week to half a month. Wash once every 2-3 days under normal conditions. Press the “Cleaning” button during operation, the main unit enters the cleaning state (automatic drainage and water inlet), and after three minutes, the drainage will automatically shut down and enter the standby state.

5. The water source of the industrial cooling fan should be in the open state for a long time, and it is required to have a water pressure greater than 1.5Kg/cm2. If there is no cooling effect when the unit is running, first check if there is water shortage (the indicator light is on), then check if there is water in the inlet pipe, whether the faucet is closed or not, and the water pressure is insufficient.

  

6. The industrial chiller unit is operated for more than one year. The evaporator needs to be cleaned once. The water pressure during cleaning should not be too high, so as not to damage the evaporator and reduce the service life of the air conditioner.

  

   According to the steps, the normal use of industrial cooling fans can delay the service life of industrial cooling fans, and can also increase the ventilation cooling effect of industrial cooling fans.

Cooling fans are divided into industrial cooling fans and domestic cooling fans.

The domestic air cooler is a summer cooling device, which can be used to cool down like air conditioners and electric fans. When it comes to household air coolers, you must first mention the air conditioning fan, which is a cooling device between the air conditioner and the fan. The cooling effect is not as significant as the air conditioner, but it is much cooler than the fan. Yuyao air cooler, Cixi air cooler

The air cooler is an upgraded version of the air conditioner fan.

Since most of the air conditioning fans on the market are not particularly effective in cooling, and ice crystals need to be added during cooling, it is very troublesome.

The cooling fan is an improved version of the air conditioning fan, which not only has a more obvious cooling effect, but also does not need to add ice crystals, which is very convenient. In addition, some brands of air coolers, as well as the purification effect of purifying air and water, that is, "double net function", can use purified water to purify indoor air to ensure that the air really cools and health.
