Heating and cooling mechanisms have become a necessity of life, especially in the last few years when global temperature has risen thanks to global warming and other factors. This is the reason cooling systems are even more in demand than ever before since they do a great job of normalizing indoor atmosphere during extremely hot weather or thereabouts.

4 Most Common Cooling Methods for Home & Offices

Contrary to what most people might imagine, cooling systems are far more complicated than heating systems since they are trying to use energy to take energy away from air, whereas it is straightforward in heating systems where energy/electricity is used to heat-up/energize the air or water. This makes making or even understanding the mechanism of a cooling device a little bit more challenging.

Having said that, let’s try and discuss the basics of some of the most common cost effective cooling methods utilized in homes and offices.

Room Air Conditioner

As evident from the name, a room air conditioner is meant to be cooling just one room effectively. Sometimes a bigger and more powerful room air conditioner can be useful for a big room too but generally, it can only do one room at most without the cooling dissipating into nothing. Usually, a typical room air conditioner would be mounted in a window or a hole in the wall with the compressor located at the other side of the wall, this allows for a sealed room with apt atmospheric control.

Central Air Conditioning System

Central air conditioners are big and are meant to supple cool air for the whole house or sometimes the whole building. Sometimes you can lump the heat pumps into the same category which also heat, or in the winter, cool the entire building by pumping the air through ducts and opening throughout the building. There are refrigerants filled coils in the compressor – usually located outside – which perform the task of cooling the air being supplied to the house.

Fun fact, the ducts and fans used here are usually the same that are used for furnace heating systems.

Evaporative Coolers

Evaporative cooling is very different from traditional air conditioning in principle, cost, efficiency, use and even in appearance. Evaporative coolers are also known as swamp coolers, they make use of fresh air by pulling it from the outside, and passing it through cool moistened pads where a transfer of heat occurs and a cool air comes of the cooler as a result. It is simple, energy efficient, and doesn’t need the space to be airtight to effectively work, in fact it is better if you keep a window open to maintain the supply of fresh air.

Split Air Conditioners

These mini-split air conditioners don’t require any ducts to circulate cold air or even big spaces in the wall or windows to be mounted. Usually, there is an indoor air handling unit which is mounted on a wall without a need to need a make a big hole in it, and secondly, a compressor nit which is located outside. Electrical conduits are used to connect the refrigerant and power lines between the two separate parts of a split air conditioner.
