Enjoy the refreshing power of Klarstein’s Air Coolers
When during summer days and the sultry sleepless nights you are looking for refreshment, an excellent contribution can be obtained from air coolers, air cooler fans, room coolers or water cooler fans. These kinds of devices represent a valid, energy efficient alternative to a traditional air conditioning unit, especially when you need to cool a room that is not too big. An air cooler is different from a fan in that it can lower the temperature just like an air conditioner.
By choosing an air cooler, you can benefit from numerous advantages. First, there is a considerable saving in both purchase and electricity consumption. In addition, the air cooler or air cooler fan only introduces healthy cooled air, which protects people from possible illnesses and health problems such as colds, coughs, joint pains and more. Finally, as room coolers and evaporative coolers are portable devices, you can easily move them from one room to another.
How does an Air Cooler or Air Cooler Fan work?
An air cooler works using the principle of evaporative cooling. Air coolers move the air, introducing air with a lower temperature into the environment through the evaporation of water and ice. Air cooler fans are equipped with a filtering system ensuring that the fan's movement triggers the evaporation process, atomising the water and ice. The hot air passes through a dust filter and then through an evaporative panel that triggers the evaporation process generating a fresh airflow in the room.
Air coolers do not need refrigerant gases or chemical components, which pollute the environment and add to the overall cost. All they needed is water or ice that is placed in an internal tank which can hold several litres so that topping up is not necessary. In this way, the air cooler or air cooler fan can operate for several hours or even a whole day. On top, the air cooler or air cooler fan can improve the indoor climate even during the winter season. In the cold, humidity regularly drops to its lowest point. As a result, skin and mucous membranes dry out faster. The air cooler can humidify the room air when needed and thus contribute to pleasant indoor climate even in winter.
How to choose the best Air Cooler for your needs?
The following overview is giving advice on the basic parameters to be considered when buying an air cooler, air cooler fan or room cooler:
- Airflow rate and power
When choosing an air cooler or air cooler fan, the power of the cooler and the airflow rate is important. In general, the greater the power of the product, the greater is the airflow rate. It is expressed in cubic metres, whilst the power is expressed in watts. Given that, the airflow rate and the power provide essential information on the capacity or the quantity of air that the cooler can regenerate in one hour. On average, an air cooler with a power of 100 watts has an airflow of about 1000 cubic metres per hour. To calculate the required airflow rate, the room's surface area must be evaluated and multiplied by the height, thus obtaining the room volume.
- Tank capacity and autonomy
Tank capacity influences the autonomy of the air cooler and air cooler fan. The larger the tank, the greater the autonomy of the device. When purchasing this product, one must also consider that the data depends on one's habits and the operating modes selected. On the display on the top of the air cooler, the user can select the mode of use and the speed setting of the fans. Increasing the fan speed will result in faster consumption of the water or ice present in the tank, therefore the autonomy will decrease. The capacity of the power tank usually ranges from a minimum of 5 litres to a maximum of 8 litres in the larger models. The advice is always to choose an air cooler that offers a better tank capacity.
The air cooler or room cooler usually has a series of controls that allow you to manage all the functions and programmes. The first type of an air cooler is the normal mode, in which the user can manually select the fan speed to adjust the air jet. In this way, the rate can be increased or decreased as required. In addition, you can use the so-called natural mode in which the air cooler works automatically, simulating some sea breeze. If you like some thermal comfort during the night, you must opt for the night mode in which there will be a reduced speed from the fan and even less noise. You can also use the air cooler during spring by using it as a classic fan. When the fan function is selected, the cold water in the tank is not used, and therefore only the fan will operate.
In almost all models, a timer function allows you to programme both the start and the shutdown of an air cooler or air cooler fan. In some cases, there is a separate auto switch-off function that is activated automatically when the appliance realises that the water in the tray is running out. Additionally, some of the more advanced air coolers use smart functions that can be controlled by remote devices such as smartphones or tablets. Most times, these air coolers are also compatible with voice assistants such as Amazon Echo and Google Home.
To maintain the efficiency of the air cooler or room cooler over time, it must be maintained and cleaned frequently. It is necessary to clean some of its internal components, particularly the valve, the tank and the filters. The cleaning of the air cooler is quite straightforward as you only need to use a damp cloth or brush with running water. All those parts destined for the evaporation process should also be checked periodically. As an extra tip you can use water with a low level of limescale to prevent any sediment from causing encrustations over time. Some of Klarstein’s air coolers rely on rechargeable batteries or can be filled directly with ice packs to provide cool air more efficiently and at a lower price. Because water evaporates during the cooling process, the warm air in the room can be humidified at the same time.
Differences between an Air Cooler vs. Air Conditioner
An air cooler with water cooling is a cheaper option and environmentally friendly to climatise a room. It does not require environmentally harmful refrigerants and works very efficient in direct comparison with an air conditioner. Especially when the air is dry like in the office, it is worthwhile to use an air cooler. The device cools with water and humidifies the air at the same time - counteracting the dry ambient air and creates a healthier indoor climate. However, this also means that the devices may not be able to achieve the desired results at high humidity. If the humidity is too high, the air should ideally be additionally dehumidified, for instance with an air conditioner. Let's summarise the main advantages of an air cooler over an air conditioner:
|Wall mounted air conditioning unit
|It can only be used to cool the air
|It can cool the air and also heat it, using the inverter technology
|It has two main parts: a fan and a water pump
|It has four main parts: compressor, condenser, expansion valve and evaporator and works on the refrigeration cycle
|It is portable and easy to move from one place to another
|It is quite bulky and heavy and should be installed on the wall or near a window
|It is envirnomentally friendly, as it uses only water to cool the air
|It works using a chemical refrigerant to cool the air
|It produces a flow of wet air
|It emits dry air
|Low energy consumption, as it's not very powerful
|As a device with a compressor, it uses more energy to function properly
|It's only suitable for use in areas with a relatively low humidity rate
|Works in both humid and dry areas
|It's ready to use: just needs to be plugged anf dilled with water
|It requires installation
