Contrary to what most people expect, air con technology is not as simple as it seems. Instead of harnessing energy to produce heat, they instead, take heat away from the atmosphere. This principle draws out heat from the inside of the room and transfers it outside; they do this by using a compressor cycle.
Air conditioners basically turn the inside of the house or a room into a big refrigerator. A compressor is placed outside which houses a special fluid called a refrigerant which changes back and forth to become liquid and vapor. Throughout the process, heat is carried from one place to another like a normal refrigerator. This may sound simple, but there’s more to it than simple exchange of heat. The process involves several controls and valves that will have you scratching your head in confusion. Air conditioners are complex yet very useful appliances, with that, here are the different kinds of air conditioning units available in markets in Singapore as well as across the globe:
Window Air Conditioner
This is a simple type of air conditioner wherein all the components- compressor, expansion coil, evaporator coil, cooling coil and condenser all compactly enclosed in a small box. This type of air conditioner is usually used in small or single rooms wherein only a small amount of cold air is needed to optimize the room temperature. They are placed on walls where a slot similar to the shape and size of the unit is oriented.
Split Air Conditioner
The split type air conditioner is a more complicated type of air conditioner as it is composed of an outdoor unit and an indoor unit. The outer unit is comprised of a compressor, condenser and expansion vave, while the indoor unit houses the evaporator or cooling oil and a cooling fan. This is suitable for individuals who wouldn’t want to bore a large hole inside their rooms and achieve instead a more minimalistic aesthetic appeal. This type of unit only needs a small hole for the draining hose. It is capable of cooling one to two rooms at the same time.
Central Air Conditioning System
This type of air conditioner is more suitable for cooling large buildings, offices, classrooms, gyms, factories, movie theaters, etc. This is a better option to consider than putting up individual units for every room as HVAC technicians would say is a very expensive option. If an entire building is to be air conditioned, the best option would be to have a centralized aircon system. In that way, the instution could save more money as it is less power hungry which then translates to lower electricity consumption. This type of unit is composed of a large compressor that is capable of producing a ton of air conditioning power enough to cool several rooms.
Other kinds of air conditioning units are available in the markets of Singapore and across the globe. However, the three mentioned are the most common and are the most popular among the different categories. Take note of the mentioned specifications, and you will be able to determine the right type of air conditioner that suits your needs.
