Summer is coming and you don’t know how to prevent the harms of heat yet? There are three alternatives: the fan, the air freshener and the air conditioner. But how do you choose? We will attempt to answer this question by way of a description of these three devices and a comparison of their respective pros and cons.
Any time if you are looking for a model go on our page that lists the best refresher fans.
What is an air cooler?
The air cooler is a device that lowers the ambient temperature of a room from 4 to 5 degrees Celsius. Its operation is based on the phenomenon of “adiabatic cooling” allowing water to release cold air when it evaporates.
Its mechanism consists of an internal fan whose airflow passes through a filter that is permanently moist. The water trapped in this filter will evaporate under the effect of the air current, thus releasing the cold and allowing the temperature to cool down.
- Easy to use, its settings are easy to set up and the device requires little maintenance.
- Its simple operating principle guarantees a solid and durable mechanics.
- The installation does not require any work to be done, as it does not involve water drainage.
- The maintenance of the appliance has few constraints, Just make sure to clean and fill the water tank.
- A reasonable water consumption ranging from 10 to 15 litres of water per day.
- The device consumes little energy, about 100 Watts for optimal use
- The temperature reduction is limited to a maximum of 10 degrees (if the device has an electric compressor).
- The device loses efficiency if the air is too humid.
- The range of the device is limited by the capacity of its water tank, which needs to be maintained.
- Precise temperature adjustment is not possible.
What is a Tower fan?
A fan is a device that creates a flow of air through a propeller that sucks air from the back of the device to propel it forward.
The fan cools us in two different ways:
- It acts like the wind by replacing the thin layer of air (heated and humidified by body heat) that envelops our body with a slightly less warm and drier air flow. This phenomenon is called convection cooling.
- The airflow provided by the ventilator facilitates the evaporation of our sweat, thus improving our perspiration, which is our natural way to cope with the overheating of our body. You should know that it is not the emission of sweat on the skin that cools us, but its evaporation.
Indeed, when sweat changes from liquid to gaseous, it undergoes a phase change that consumes a lot of energy to our skin, it is called “latent heat phenomenon of evaporation”. Thus, the ventilator facilitates and accelerates the evaporation of sweat, chasing around our body the air moistened by our skin to replace it with drier air.
- The fan is generally a low-cost cooling depending on the quality and options it provides.
- Its energy consumption remains quite low compared to other types of ventilation such as air conditioning.
- The fan does not ensure the renewal of the air, it only stirs it, which can cause problems of scattering dust and microbes in the room that you want to refresh.
- Subjected to too much exposure to airflow, the device can cause problems with drying out and dehydration of the occupants.
What is an air conditioner?
An air conditioner works differently because it does not vacuum through the air to cool it. Indeed here the device creates a transfer of heat between 2 bodies, air and refrigerant.
The unit must maintain this refrigerant at high pressure to keep it cold. This is what requires a lot of energy in an air conditioner. This is why the device releases a lot of heat, to remedy this an evacuation is often installed outdoors to return the excess heat.
- Optimal Cooling
- Cools surfaces of more than 100 m2
- Fresh, dry air
- Silent indoors
- Noisy outdoor evacuation
- Excessive price
- Not eco-friendly
- Unsy pleasant air see nausea
To put it simply:
After a presentation of these three types of cooling a question remains unanswered, which one to choose? Well it will depend above all on your budget and the humidity of your room.
In conclusion, your choice should take into account the different uses you will make of your device as well as where you want to install it.
