Regarding the air cooler, there are wet curtain air coolers in front, etc. Below, we will come to familiarize with another type, which is an evaporative air cooler, which can also be called an environmental air conditioner, an air conditioner air cooler and an evaporative air cooler. Its main role is that ordinary air coolers are cooled for ventilation. Moreover, it also has functions such as dustproof and deodorizing. Therefore, it can be considered as an evaporative cooling and ventilation unit.

   1. The use conditions and environmental requirements of the evaporative cooling fan

   For the evaporative cooling fan, the conditions of use are as follows:
   Temperature: 18 ° C - 45 ° C

   Relative humidity: 85% or less.

   Atmospheric pressure: 86kpa—106kpa

   Water supply: The water should be softened, and the water supply temperature should not exceed 45 °C, and the water supply pressure is 0.15-0.6 MPa.

   Power supply: The deviation of the power supply voltage should not exceed 5% of the rated voltage.

   For the environmental requirements of evaporative cooling fans, the main requirement is that there are no corrosive gases or substances in the environment, and there should be no open flame or fire source to avoid danger.

   2. Precautions for evaporative cooling fan

   (1) When connecting the inlet pipe and the drain pipe, the connection should be correct and good, and there should be no leakage or leakage, so as to avoid damage to the air cooler or serious consequences.

   (2) On the evaporative cooling fan, no items can be placed to avoid affecting the heat dissipation of the device or its damage.

   (3) For the maintenance work of the chiller, it should be carried out under the power-off state, and it should not be carried out during its operation, because it is very dangerous and it is easy to get an electric shock.

   (4) In the course of use, if there is any abnormality, it should be stopped immediately and handled by professional maintenance personnel. It is strictly forbidden to handle it without authorization or privately.

   (5) For the power cord, it should be connected correctly and firmly, and also have a good grounding treatment to ensure its safe use and operation. In addition, if there is dust, dust, or particulate matter in the air, a filter can be added to protect it.
