What Is Central Air Conditioning System?

Central air conditioning system is a system which operates by cooling air at a central place and distributes the cooled air to and from rooms with the help of one or more fans and ductwork. What makes the whole idea of air conditioning feasible is the operations of the air conditioner compressor. When it cooling gas is compressed, it allows it to absorb heat from the house and blows it outside into the outside air and that’s exactly how the cool air is being generated.

Central air conditioning are of two main types which includes a split system as well as a packaged unit.

Generally, in the split system AC unit, both the condenser and compressor are included in the outdoor metal cabinet, whereas the indoor cabinet includes the evaporator. Typically, in several split system air conditioning units, the indoor cabinet will also include an air handler or a furnace. What’s more? The evaporator coil of the AC unit is fitted in the cabinet or the furnace or heat pump’s primary supply duct. This type of central air condition is usually the most economical AC unit to fit if you already have a furnace in your home.

However, in a packaged central air conditioning system, the components including condenser, compressor and evaporator are all included in one cabinet. Supply of air as well as the return ducts are connected through the home’s exterior wall or roof to the package central air conditioning system - mostly placed outdoors. This type of central air conditioners also features electric heating oil or a natural gas furnace. With this perfect blend of central heater with air conditioner, there’s simply no need to a separate furnace indoors.

Several individuals think that the the way their air conditioning system works is simply by pumping hot air out of their homes or offices, blowing a cool air in return. This is absolutely wrong! The hot air is, in fact, cycled back in as cold air and this process continues until the thermostats gets dropped down to the required or set temperature. The air conditioning system manages this in a similar way to how the refrigerator manages to stay cold and of course, excluding the insulated box.

The short and simple answer to the question of what gas an air conditioning use is Freon. This is a non inflammable gas which is subjected to the evaporation process over and over again in most refrigerators to keep the temperature at a low level. This same process is repeated in air conditioning systems. Now let’s take a look at how the Freon gas is incorporated in AC systems.

The cold Freon gas is firstly compressed by a compressor in the air conditioner. The gas is then combined with a little quantity of oil in order to lubricate the compressor. When Freon gas is compressed, the pressure is increased which makes it incredibly hot. It then moves through a couple of coils which works to lowering the heat and turning it to liquid. This Freon liquid will then be transmitted via an expansion valve which causes it to cool down until evaporation takes place. The outcome of this is a low pressure cold Freon gas which is then transmitted via another set of coils allowing the gas to collect the heat and lower the air within the room.

The air conditioner now filters the air and clears out the dust, smoke, pollen and other kinds of air pollutants. The system also absorbs excess liquid from the air too which it uses to cool down the system and pump it through a hose.

As the heat start to come up especially during the summer months, the swelter will mercifully be kept in check by air conditioning. The technology has made a significant impact on modern life and it can now be considered a norm for all new and modern homes. So if you’re also planning to fit new HVAC air conditioning systems in your home or property, you may also be interested in knowing exactly how it works. In this article, we aim to provide you with an in depth insight into how air conditioning operates. Now let’s take a closer look at the process!

✓ A grille at the bottom of the machine absorbs warm air from the room

✓ The warm air is transmitted over some chiller pipes through which a coolant fluid is circulating. Working in a similar fashion as the chiller cabinet in a refrigerator, this part cools down the transmitted warm air and any excess moisture is duly removed by a dehumidifier.

✓ The air is then transmitted over a heating element which is quite similar to the one present in a fan heater. On a cold day, this part of the unit can be turned up in order to allow the HVAC works as heater.

✓ A fan which is positioned at the top blows the air back through another grilled into the room.

✓ Coolant flows through the the chiller pipes. In the process, it carries heat from the air blowing past the pipes and then it evaporates - converting the cool liquid into a hotter gas. This heat is then transported to the outside of the building from inside the room.

✓ With time, the heat inside the building slowly blows away into the outside air.

NO - as air conditioning systems use fluorinated gases as refrigerants, all work on them must be done by professionals holding valid F-Gas certification. There is a range of different qualifications and certifications that apply for this, so it's always best to ask someone who is qualified to do this.
