Get Evaporative Coolers – Increase the Comfort of Your Home
If you have been thinking about getting an air conditioning, you should try evaporative coolers. An evaporative cooler (also called a desert cooler, and a humid air cooler) is a device that cools the air by evaporating water. Evaporative cooling is different from typical air conditioning systems that use refrigeration cycles by vapor compression or absorption. The principle of operation of evaporative cooling is based on using the large enthalpy of vaporization of the water. The temperature of the dry air can be significantly reduced by the phase transition from liquid water to water vapor, which requires much lower power consumption than the energy consumption of the units operating by cooling. If you want to keep your body at a normal temperature, then you should install evaporative coolers at your home. You need to know that it is completely a natural process, so it will not affect throat, eyes and skin like traditional refrigerated cooling.
Why Should You Use Evaporative Coolers?
Air washers and wet cooling towers use the same operating principles as evaporative coolers but are optimized for purposes other than cooling air inside a building. For example, an evaporative cooler can be designed to cool coils and pipes of a large air conditioning system in order to increase its efficiency. Evaporative cooling is especially suitable for climates in which the air is hot and humidity is low. The air conditioning by evaporation is popular and appropriate in the southern area of Australia. In dry and arid climates, the costs of installing and operating an evaporative cooler can be much lower than the costs of an air conditioner by refrigeration cycles, often in the order of 80% less.
However, air conditioning systems are sometimes used in combination with evaporative cooling and steam compression systems for optimal results. Some evaporative coolers can also be used as humidifiers in the cold season. In extremely dry climates, it also has the additional benefit of conditioning the air by adding moisture for the comfort of the occupants of the house. Unlike refrigeration, devices that work based on evaporation require a water source and consume water continuously for its operation.
For example, in industrial plants, commercial kitchens, laundry, dry cleaning, greenhouses, refrigeration of specific sites (loading areas, warehouses, factories, construction sites, athletic events, workshops, garages) and agricultural practices in closed environments (poultry, pig and dairy cows), systems based on evaporative cooling are often used.
Benefits of Evaporative Coolers
Tried and tested method: Evaporative cooling is one of the oldest and proven cooling methods. It is a natural effect created by the evaporation of water.
Environment friendly: The necessary energy is extracted from the environment in the form of heat, making the operating environment friendly. Everyone knows about practical effects and applications such as the butter cooler, earthenware jars that are kept moist and allow evaporation through the open-pored surface.
Excellent cooling effect: Since the entire energy content does not change in the evaporative cooling, the change of state thus always runs on the enthalpy lines from top left to bottom right. At relative humidity of 100%, the saturation line is reached. In Central Europe, this can generally provide a cooling water temperature of around 27 ° C at an outside temperature of 32 ° C, that is, a temperature well below the ambient temperature.
Self-running: Evaporative coolers use a high-to-low temperature heat transfer process enhanced by phase transition, and thus a self-running, “clockwise” cycle. Therefore, no mechanical, electrical or thermal energy is needed except for the transport of air and water.
It can be concluded that if you want to make your home more comfortable, you should opt for evaporative cooling.
