Installation and Components of Air Conditioning

There are many types of air conditioning systems that can be used in the home, including window units, portable air conditioners, ductless air conditioners and central air conditioning systems. Despite their differences, however, the physics of how they work is the same, and they all use the following components and direct expansion refrigeration. In principle, it works very much the same way as your food refrigerator. The three basic parts of an air conditioner are the evaporator, the compressor, and the condenser. The evaporator can be found on the part of the air conditioner inside the house, while the compressor and condenser are located in the outside unit.

Regardless of the type of installation, all air conditioning unitsconsist of four major components that are:

Evaporator
An evaporator is basically a heat exchanger coil that’s responsible for collecting heat from inside a room through a refrigerant gas. This component is known as the evaporator, and is where the liquid refrigerant absorbs heat and evaporates to become gas.

Compressor
As the name clearly signifies, this is where compression of the gaseous refrigerant occurs. It’s located in the outside unit, such as the part that’s installed outside the house.

Condenser
The condenser receives the vaporized refrigerant from the compressor, converts it back to liquid and expels the heat outside. Needless to say, it’s also located on the outside unit of the split Las Vegas air conditioning.

Expansion valve
Also referred to as the throttling device, the expansion valve is located between the two sets of coils which the chilled coils of the evaporator and the hot coils of the condenser. It keeps tabs on the amount of refrigerant moving towards the evaporator. Note that in the case of window air conditioning units, the three aforementioned components are all located inside a small metal box that is installed in a window opening.

Air conditioning units are found in any place that requires cooling and this includes homes, cars, hotels and even ships. To simplify things we’re going to limit the scope of this discussion to central air conditioning systems, most of which are split or central systems which those air conditioning systems commonly found in homes and offices in which some of the parts that make up the air conditioning system are found inside of the home or office building and other parts are located outside of the home or office building.

Modern life wouldn't be as comfortable as it is without air conditioning technology. It’s important to know and understand that air conditioning systems are closed pressurized systems. Flowing through the system is a coolant that facilitates heat transfer. This “fluid” is called the refrigerant. The refrigerant is a chemical compound with the physical and chemical characteristics necessary to facilitate the proper operation of the system. This means that it needs to have the correct boiling point, freezing point, etc. to allow for the system to work correctly. If the chemical doesn’t meet the exact criteria required by the system then it cannot be used.


Your Las Vegas air conditioning system needs to be maintained just like any other aspect of your home's HVAC system.

How Air Conditioning System Works


Air conditioning system essentially has four parts: an evaporator, a compressor, a condenser and an expansion device.

The part inside the home where the refrigerant evaporates is the evaporator, naturally. Fans in the home blow air across the evaporator's coils. The cooling fluid reaches the compressor as a low-pressure gas. The compressor squeezes this gas/fluid, and the molecules in the liquid are packed closer together. The closer the compressor forces these molecules together, the higher the temperature and energy rise. This working fluid exits the compressor as a high-pressure, hot gas, and it moves to the condenser. The outside unit of an air conditioning system has metal fins all around the housing. These fins work like the radiator on a vehicle, and they help dissipate heat more quickly.

As air from the house moves across the evaporator, refrigerant within the coil picks up the temperature of the air. The refrigerant is absorbing heat from the air and turns from a liquid to a vapor. It went from being a cold liquid to a hotter vapor, and at the same time, the air had heat removed from it, so the air went from being warmer to colder.

Indoor Air Conditioning Unit
The indoor unit is typically located in a closet or basement, and is near where your furnace filter is located. The unit consists of a coil box that contains what is called an evaporator.  The evaporator allows for the refrigerant a cooling fluid inside the coil piping or to evaporate and absorb heat. Once the heat is absorbed from inside your home, it leaves nothing but cool air to be sent back into your home.

Just as water absorbs heat from your stove in order to boil (or evaporate) refrigerant absorbs heat from your house. This means that both water and refrigerant turn from liquid to vapor as they absorb heat.

Outdoor Air Conditioning Unit

The outdoor unit is usually located in the rear or side of your house and it is where the heat from inside your home is dispersed. It contains the compressor, condenser coil and a fan. The heat absorbed from your home’s air is transferred to the refrigerant and then pumped to the outdoor unit. As this heat is absorbed and moved by the refrigerant to the outdoor coil, it passes through the compressor.

The compressor in your Las Vegas air conditioning system has the primary job of moving the refrigerant throughout the system. This is important as we can then keep reusing the refrigerant to cool our house. The refrigerant is compressed to a higher pressure, and moved through the outdoor coil known as the condenser. As the refrigerant passes through the condenser, a fan delivers ambient air across the condenser coil causing it to cool.

As the process completes, the heat from inside your house is dispersed to the air outside your house. The refrigerant is then pumped back indoors and the whole process repeats.

The entire process of making the air in your property a comfortable temperature is based on a very simple scientific principle, and the rest is achieved by mechanical means.
