An air conditioning system plays an important role in the quality of the air that circulates inside your home. When the hot or humid season arrives, an AC unit will help lower the temperature inside your dwelling, says a seasoned provider of air conditioning in Sutherland Shire (http://easternairconditioning.com.au/) . 

There are different types of air conditioning units that are available in the market. Some people prefer a window type or a split type air conditioning unit, while others use a central air conditioning system to keep their entire house cool, comfortable, and pleasant to live in.

What is a Central Air Conditioning System?

According to Lennox’s website, a central air conditioning system is a piece of cooling equipment that collects and processes the air inside your house at a central location and then distributes it back using the installed fans and ductwork. 

Central AC systems function by collecting the warm air inside your home through the use of an air handling unit. The warm air will be sucked into the installed ductwork and processed in a central location where the compressor will pump the refrigerant into the evaporator coil so that it can absorb the heat from the collected air.

After the heat is absorbed, the cool air will be circulated back to your property passing through the ducts and vents that are installed to lower the temperature inside your house. This cycle is repeated continuously to ensure that the temperature is always kept cool and comfortable.

Two Types of Central Air Conditioning System

Based on the information provided by the Department of Energy, there are two types of central air conditioning systems, the split-system unit, and the packaged unit.

Split-System Central Air Conditioning System

A split-system unit is the most common and more affordable type of central air conditioning system that is used in the United States. This AC system is made up of two pieces of equipment, an outdoor unit that contains the compressor and the condenser, and an indoor unit that houses the evaporator.

Packaged Central Air Conditioning System

A packaged unit is a type of central air conditioning system that combines all the AC components into a single housing unit (evaporator, condenser, and compressor). The equipment is usually placed on the roof of the property or along its exterior walls.

This type of central air conditioning system is commonly used in business establishments and commercial buildings.

Four Major Components of a Central Air Conditioning System

A central air conditioning system is made up of four major components which include the evaporator unit, the condenser unit, ductwork, and thermostat.

Evaporator Unit

The evaporator unit is usually located inside your property. Its function is to draw the air across the evaporator coil so that the refrigerants that it contains can absorb the heat from the air. 

After the heat is absorbed, the air is blown back inside your property by the air handling unit so that it can lower the temperature inside your house.

Condenser Unit

The condenser unit of a central air conditioning system is normally housed inside a metal cabinet that is located on the roof or in a concrete pad along the exterior walls of your property. Its function is to exude the heat that the refrigerant has released after it is sent by the evaporator unit.

After the refrigerants have released the heat, it will be pumped back inside the property to continue with its cooling functions.

Ductwork

The ductwork is a system of tubes (commonly referred to as ducts) that are used to transfer air from your AC unit (or heating equipment) throughout the entire property. This system of ducts spreads out into every corner of your property and each branch ends with an air register that features adjustable grilles that you can use to control the flow of air inside a particular room.

Thermostat

The thermostat serves as the control center of your entire central air conditioning system. Its function is to monitor the ambient temperature inside your property so that it can prompt the AC unit to run whenever the predetermined conditions of your selected settings are triggered.  

Advantages of Using a Central Air Conditioning System

Using a central air conditioning system for your home provides you with the following advantages:

  • The filters that are used by a central air conditioning system dramatically improves the air quality inside your house
  • In comparison with other types of AC systems, a central air conditioning unit generates less noise
  • Using a central air conditioning system will save you valuable space because you will only need one unit to cover your entire house
  • It is easier to use because the temperature of every room inside your house can be controlled using a single control panel
  • It is more energy-efficient because it effectively circulates the cool air throughout your entire house 

Final Words

Choosing the right central air conditioning unit for your home is a great way to make the environment inside your house cool, clean, and comfortable. Knowing how it works and what the function of each of the components are will help you in your task of selecting the best central AC unit that you and your family will enjoy.
