How Do Evaporative Coolers Work? Answer For You

While it has been urgent for both houses and commercial places to find an efficient, energy-saving way to cool the environment or other places in an environmentally friendly way, among various coolers, evaporative coolers enjoy more and more market share for their good performance with low energy consumption. Therefore, the following questions come up: how do evaporative coolers work? Why is it an important alternative to the advanced technology of air conditioning?

As one of the leading evaporative cooler manufacturers in China, Wanjiada will explain the operating principle of the evaporative coolers, which would help you understand how this energy-saving cooling equipment works.

Evaporative Coolers Working Principle

The principles of the evaporative coolers are simple and yet very effective, their process has something to do with the “natural wind” in our everyday life. Once the weather is felt hot, evaporation of moisture in the air would make it cooler. Evaporative coolers take this natural occurrence intelligently to develop an appliance that could cool things down in a very short time. More specifically, the work process of evaporative coolers may be divided into the following.

Inhaling External Hot Air

The first step of an evaporative cooler is to inhale external hot air into the machine through a built-in fan. This hot air usually comes from the outside environment, which may be hot air outside or warmer air indoors. After the air is inhaled, it will be guided through the cooler’s internal cooling system – the cooling pad.

Water Evaporation Absorbs Heat and Cools Down

The pad is the core in the evaporative cooler. It is usually made of some special materials such as highly absorbent fiber materials which are able to absorb water rapidly and keep it moist. When hot air blows through these moist cooling pads, evaporation of water absorbs the heat in air. It operates on the physical principle of evaporation, where water changes its state from liquid to gas by absorbing heat from the air, hence having the effect of cooling down the air temperature.

For this principle to take place, there is considerable heat exchange in which the air temperature drops while the moisture gradually changes to water vapor. Since this process does not require any refrigerant, it is also environmentally friendly and another natural way of cooling down.

Cool Air Flows Into the Room

During the process, the hot air turns cool after passing through the wet cooling pad and cools down effectively. The fan at this point pushes out this cooled air and it flows into the room or area that needs cooling via the outlet. As a result, the indoor temperature decreases bit by bit, and the air will be more humid to produce a comfortable cool feeling.

Water Circulation Keeps it Moist

The water pump will keep pumping during the whole process of evaporation so that the cooling pad is always wet. It pumps water from the water tank and sprays it onto the cooling pad to recover the lost water through evaporation. That way, the humidity of the cooling pad can always be maintained to sustain consistent evaporative cooling.

Continuous Circulation Maintains Cooling Effect

Evaporative coolers always work in a continuous cycle so that the cooling effect can be maintained for a long time. The fan continuously inhales the external hot air, and the water pump continuously replenishes water to the cooling pad, repeating the above cooling process. This working mode is energy-saving and effective at maintaining a long-lasting cool environment over a large area.

Summary

The working principle of the evaporative cooler is to use the phenomenon of evaporative cooling in nature. It uses such a physical property that when water evaporates, it absorbs heat, and through the cooperation of the water pump and the fan, it takes away the heat in the air, thereby achieving its cooling effect.

By contrast, evaporative coolers do not rely on traditional refrigerants or complex compressor systems like most air conditioners. They have a simpler design, higher energy efficiency, and lower operating costs. Especially in dry and hot climates, they can provide a more comfortable and healthy cooling experience.

Why Choose Evaporative Air Coolers?

Compared to traditional air conditioners, evaporative coolers possess many advantages owing to special characteristics, particularly in dry hot areas, and are especially suitable for large space-open areas. Following are a few advantages of evaporative coolers.

Highly Efficient and Energy-Saving

Evaporative coolers use much less energy than conventional air conditioners. Because they use only evaporation of water for cooling, they do not need high-energy compressors or refrigerants. This not only saves them electricity but also greatly reduces operating costs.

Environmentally Friendly and Healthy

It does not use any chemical refrigerants and will never result in pollution to the environment. Due to the natural evaporation process it performs, it will also be much friendlier to human health. It is also effective in increasing air humidity and is very suitable for dry environments, rather than causing drying of air like traditional air-conditioners.

Suitable for Large Spaces

Evaporative air coolers are highly suitable for large spaces or open areas like garages, warehouses, factories, shopping malls, etc. An evaporative cooler is more flexible and can efficiently cool the entire area compared to traditional air conditioners, which require multiple indoor units and complex pipe installation.

Low Maintenance Cost

The evaporative cooler structure is simple, and the machinery requires relatively low maintenance. Usually, maintenance just involves changing the cooling pad regularly and cleaning the water tank from time to time; thus, it costs very little.

Suitable for Dry Areas

The working efficiency for the evaporative air coolers is quite great in dry climates. When the relative humidity of air is low, water will evaporate much quicker and consequently provide a more sensible cooling effect. Therefore, the use of evaporative coolers will be highly suitable for desert areas or places where summers are warm and dry.
