Like the instruments in an orchestra, the numerous components of an air conditioner play off one another to produce the desired effect and cool or heat the space. The many parts that make up your air conditioner’s flawless operation are hidden inside the inconspicuous box unless anything goes wrong. A closer inspection reveals a complex web of air conditioning accessories connecting the various parts of an AC system.
Components of a cooling system.
The evaporator coil for a mini-split system is housed in the interior unit, whereas in a central system, it is positioned in the air handler. The evaporator coils are where the system’s refrigerant, which is constantly circulating, is cooled to a shallow temperature. When your HVAC system pulls hot air from your home and blows it over the evaporator coils, the heat is pulled out of the air, and the air is cooled. The cooled air is blown back into the house by fans behind the evaporator coil.
These coils can also be fabricated from steel or aluminium and the more common Copper. Copper is the material of choice because of its high heat conductivity, low cost, and ease of maintenance.
However, dirt and dust can accumulate on coils, reducing their performance. This dust can also accumulate in the condensation drain, leading to a blocked drain and leaking refrigerant. Even while the air filter helps to maintain the evaporator coils in good shape, it still has to be cleaned once a year to ensure optimal performance.
The compressor is the heart of every air conditioner and arguably the most crucial part. The compressor for central and split systems is found in the outside condensing unit. The air conditioner’s compressor is the primary energy consumer and typically the system’s priciest component.
As its name implies, a compressor’s job is to squeeze the heated vapour of the refrigerant so that it condenses into a hot liquid. It is then chilled and expanded again to remove heat from the inside air while the air conditioning continues. There will be more on this later in the piece.
The polar opposite of the evaporator’s condenser coil removes heat from the refrigerant and releases it into the surrounding air. Your air conditioner’s exterior condenser is where you’ll find it.
As opposed to the condenser, which is responsible for dissipating heat, the evaporator coil is responsible for absorbing it. A heated breeze will flow from the external unit of your air conditioner if you stand outside it. The condenser releases heat when turning the refrigerant from a vapour to a liquid.
The Pressure Relief Valve
The expansion valve is a small device between the condenser and the evaporator. Due to its new state as a liquid, the refrigerant will not perform its cooling function. The refrigerant is rapidly cooled when it expands into a gas in the expansion valve, which also causes a reduction in pressure. The cooled gaseous refrigerant is recirculated via the evaporator coils.
Discuss the interplay between the various parts of an air conditioner
With the help of the compressor, the refrigerant is transformed into a heated, high-pressure liquid. This liquid is directed into the condenser coils using air conditioning accessories, where a giant fan cools it. The next part of a refrigeration system is an expansion valve, which quickly expands the refrigerant to turn it into a low-pressure, chilly gas. The cooled gas lowers the temperature in the room. The evaporator coils are where this process takes place. When the coils grow cold, the interior unit’s fan pushes the warm air over them, lowering the temperature. Whoa, that was easy.
