Evaporative coolers are a more environmentally friendly alternative to typical air conditioners. They may help you save money on cooling, but they aren’t suitable for every house. So, how exactly does an evaporative cooler function? Could it help you save money on energy? Discover more by reading on.
Please bear with us while we explain the science behind this.
A considerable amount of heat is retained by liquids. When they evaporate, the heat acts as an energy source, converting the molecule from a liquid to a gas. When a molecule escapes as a gas from a surface or region, it carries heat with it.
You’ve most likely seen this occurrence in hot weather. When we sweat, the liquid perspiration on our skin evaporates, carrying heat with it and leaving us feeling colder. Evaporating water molecules help chill the air in the case of an evaporative cooler.
What Exactly Is An Air Cooler?
Evaporating water into the air is an efficient form of cooling, and evaporative coolers use this concept to drop air temperature by 15 to 40 degrees. Evaporative air coolers suck in fresh air from outside and pass it over wet pads, causing water to evaporate into the air.
The primary difference between an evaporative cooler and a conventional air conditioner is that an evaporative cooler constantly pulls fresh outside air into your house rather than circulating and cooling the interior air. There is no need for a refrigerant or coolant since water evaporates. Evaporative air coolers, unlike air conditioners, need an open window to enable air to enter the system and warm interior air to escape your house.
Evaporative air coolers are also substantially less expensive to install than regular air conditioners, often costing roughly 50% less. They are also less expensive to operate since they utilize just 25% of the energy that an air conditioning system does.
However, evaporative air conditioners have several drawbacks. For starters, they are unsuited for humid places since the air is already damp. This limits the cooling capacity of the device. They’re also more time-consuming to maintain than standard air conditioners, requiring draining and cleaning at least once every season and up to many times per month during hot weather.
What exactly is a Swamp Cooler?
A swamp cooler is a different name for an evaporative air cooler. Despite their unusual name, swamp coolers are not suitable for swampy, humid climates. In reality, they are only appropriate for places with low relative humidity.
Is an Evaporative Air Cooler Effective in Cooling a Room?
Evaporative air coolers frequently receive a poor name for their capacity to properly chill air, yet they may be a useful choice for certain households. If you reside in a low-humidity environment, an evaporative air cooler may perform just as well as a standard air conditioning system.
However, you won’t get the full advantages of an evaporative cooler unless you purchase a unit big enough to chill the area you wish to cool. Check the manufacturer’s recommendations carefully to confirm that the unit you’re thinking about is appropriate for your indoor climate and room size. If the room you wish to chill is a high-traffic area with several inhabitants, receives a lot of sunshine, or has equipment that creates heat while in use, you might consider getting a more powerful unit.
