Air Conditioners

What is air conditioning?

Air conditioners are often refereed as AC or air con, it is the process of removing heat and moisture from the interior of an occupied space and also release the cool air into an interior area. In fact, air conditioners and refrigerator work the same way. The way of air conditioner works is to use chemicals that can easily convert gas to liquid, and repeat the process again and again. The chemicals inside the air conditioners can transfer heat from the air inside of an interior space to the outside air.


The history of air conditioner

The air conditioner was invented by an American engineer named Willis Carrier. He invented the first modern air conditioner. However, the idea of using evaporated water or liquids to cool a high temperature space was far before Carrier’s 1902 invention. The first known systems that used water to cool down an interior space were created by the ancient Egyptians. The Egyptians would hang wet mats over their doorways to lower the temperature in their homes. The evaporated water from the wet mats can reduce indoor air temperature and also add refreshing moisture to the dry desert air. Technically, the way that the Egyptians cool their homes was the earliest development of air conditioning system.


The structure of an air conditioner

An air conditioner comprised of three main parts, compressor, condenser, and an evaporator. The compressor and condenser are usually located on the outside air portion of the air conditioner. And the evaporator is located inside the house.


How does an air conditioner work?

An air conditioner is a central heating and cooling system provides cool air through ductwork inside our houses, by providing a process that removes the hot air inside.


What are split air conditioners? 

A split air conditioner consists of an outdoor unit and an indoor unit. The outdoor unit is installed on or near the exterior wall of the room that you want your air conditioner to be installed. The outdoor unit includes compressor, condenser coil and the expansion coil or capillary tubing. The indoor unit contains the cooling coil, a long blower, and an air filter. The type of air conditioners are much quiet than the traditional ones because the compressor and fan for the condenser are located outside the room. By this means, the major sources of noise are removed.


What are the benefits of split air conditioners?

The most appealing benefit of installing a split air conditioner is it can decrease the energy expenditures. Using centralized air conditioning units tends to lose a great amount of energy because of the heat exchange in the duct system. However, a split air conditioner does not use such ductwork. Therefore, it can save some money for a household. Another benefit of a split air conditioner is that it is easy to be installed. Next, it provides great flexibility. Individual rooms can be supplied with their own cooling units, and the feature is cost effective and useful for rooms that are rarely used. With a split air conditioner, each room can maintain in the temperature that is suitable for individuals.  


What is an air cooler? Is it different from an air conditioner?  

Many of us have heard of air coolers, but are they the same as air conditioners?
Actually, the way they work is different. The most distinctive difference is that air coolers cool the air by water, whereas air conditioners can both cooling and heating the air by using chemicals. Both of them have their pros and cons.


Differences between air coolers and air conditioners

Air conditioners provide both cooling and heating, and the way they work take    less time to cool or heat a space. However, they can only being used indoors and require a lot of electricity. For air coolers, they only provide cooling function. They are more energy efficient, but also take more time to cool a space. They can used both indoor and outdoor and outdoor, and are more eco-friendly than air conditioners. The choice depends on each customer’s preference.
