How the evaporative coolers work

evaporative coolers are considered to be a suitable choice for providing cooling in areas with a dry climate where the maximum relative humidity is 35%. evaporative coolers, in addition to providing cooling, also contribute to the softness of the air inside the houses. Therefore, it is not recommended to use evaporative coolers in the northern and southern regions of the country.
The average power consumption of a water cooler is around 300 watts, while the average power consumption of a gas cooler is 1500 watts. Electricity consumption in evaporative coolers is about 0.25 times that of gas coolers compared to gas coolers. Using evaporative coolers to create cooling in buildings is a common method from the past because they are relatively cheaper and consume less energy than other models of air conditioners (air conditioners, etc.). Of course, considering the growing problems and crisis of water shortage in the country, each water cooler consumes about 300 to 400 liters of water per day, so it is necessary to pay attention to the country's water crisis when choosing.

In fact, the water cooler is a metal or plastic box with open sides for air suction. The centrifugal fan that is installed inside the water cooler is rotated by an electric motor and it causes the air to flow into the water cooler. On the other hand, the water pump installed in the water cooler compartment continuously moistens the cooler's covers in order to continue the cooling process. The air is passed by the fan through the openings in the air cooler valves and through the wet cloths, and this cool air is transferred to the room through the channels through a vent in the ceiling or wall. In fact, evaporative coolers cool the ambient air through water evaporation.

On the other hand, the low maintenance cost of the water cooler is possible due to the presence of only two mechanical parts in the device (motor fan and water pump). Over time, if repairs are needed, these parts can be easily replaced and repaired by the owner at a low cost.
In case of using evaporative coolers with covers, it is necessary to change the cover of your water cooler at the beginning of the summer season (June) and once again at the end of July or the beginning of August, in addition to changing the cover of your water cooler every year, so that at the same time, For health and coolness, use your water cooler with confidence.
