Cooling through evaporation is a natural process. Sweat and perspiration are the most common examples. Evaporative cooling is based on the fact that water must have heat applied to it to change from a liquid to a vapour. When evaporation occurs, the heat is taken from the water that remains in the liquid state which results in a cooler liquid.
The process of evaporative cooling system, we also need to understand heat and evaporation. Water can hold a lot of heat without changing temperature. The heat stored in water is called latent heat. It becomes cooler when water absorbs the surface heat. When water absorbs heat, it evaporates or changes from a liquid to a gas. The gas leaves the surface, taking the extra heat with it. This results in a decreased amount of heat and thus, the temperature on the surface. This is how evaporative cooling works. Think of how boiling noodles on the stove works. The stove transfers heat to the water in the pot. The water absorbs the heat, and then leaves the pot as steam, taking the heat with it.
Evaporative cooling is a very important and is used in both biological and mechanical processes. Our bodies are designed to sweat and to release heat keeping our body at its natural temperature when it gets too hot. Our skin releases sweat, which contains water. The water absorbs the heat from our skin and it eventually evaporates, taking the extra heat in our skin with it. This decreases our body temperature and keeps us from overheating in the summer.
There is no need to suffer through the summer heat when cheap, energy-efficient air conditioners are widely available. Many brands now have highly energy saving star-rated air conditioners that are also exceptionally designed for local climatic patterns and consumer requirements. Nowadays, the air conditioners are not just cooling devices but also have new features such as humidity control, air purification, non-toxic refrigerants, etc.
Important tips to follow on selecting the best air conditioners for your home:
Capacity:
One should always consider the capacity of the evaporative cooler depending on the floor size of the room for which the air conditioner is required. Proper guidance is needed with proper measurements to choose the right air conditioner.
Type of Air Conditioner (Split or Window):
Another important factor is whether you want a window air conditioner or split model. Window units are cheaper and easy to install and maintain. On the other hand, split air conditioners are quieter and provide a pleasuring effect with better air distribution.
Product Pricing:
As you consider buying an air conditioner with more features and higher star ratings account for a slightly higher price tag. For every star rating increase, there is an increase in the price. An inverter air conditioner is mostly priced higher than a 5-started split air conditioner.
A quality of air:
A good air conditioner with a good filter keeps the air clean and also enhances the overall performance by keeping a check on dust and pollution.
Installation:
Window air conditioner is a more compact unit designed to be attached to the windows. A split air conditioner has a compressor unit outside the house and one indoor unit inside the room, specially designed for the better flow of air.
Maintenance and cleaning:
Air conditioners need regular servicing to remain in the best condition and maintain the performance.
Cooling speed:
Air conditioner should have the feature to control the temperature settings for different climatic conditions.
Keeping in mind all the above points one needs to have enough knowledge about various available models and brands in the market.
