Living in one of the hottest countries in the world, it’s crucial to find ways to beat the heat during the summer months. Aside from air conditioners, portable ACs and fans, another option is evaporative cooling. So, what is evaporative cooling and how does it work? Read this evaporative cooler guide from Canstar Blue to find out more.
What is an evaporative cooler?
An evaporative cooler is a cooling appliance that uses evaporation to cool a space. They are a cheaper option of cooling appliance in comparison to other air conditioning appliances, and are generally portable, making them a great choice if you want to move them from room to room.
How do evaporative coolers work?
An evaporative cooler cools the air by evaporating water. Each model contains a fan which draws warm, stale outside air into the appliance and then passes it over water-soaked pads inside the unit in order to cool the air. Since the cool air is continually circulating and creating a breeze, your ambient temperature can feel a few degrees lower than the actual temperature in the room.
Evaporative Cooling vs Air Conditioning
Split-system air conditioners are divided into two units – indoor and out – and while evaporative coolers also have two components, the process is different. Split-system ACs replace the hot air inside with cooler air from the outside, plus use refrigerant gas to reach the desired temperature inside the home quickly. It works in any climate, especially humid areas, unlike evaporative coolers, which may have to work harder to produce a refreshing breeze and climate.
Benefits of an evaporative cooler
Evaporative coolers offer a number of benefits that could help you lean towards buying one, including:
- Ideal for dry heat climates, and can help mitigate materials such as wood cracking and warping in drier climates
- Cheaper to purchase, install and run than an air conditioning unit
- Improves indoor air quality
- Can be more energy efficient than other cooling appliances
