Think you know your AC system? Below are five vital components that make your heating and cooling unit operate smoothly.

The Compressor

The compressor is the most important element in an air conditioner. An AC compressor converts gas into liquid while assisting in the AC unit’s cooling process. The compressor is responsible for channeling the refrigerant in a continuous cycle so that the entire system is cool. The compressor also transforms low-pressure gas into a high-pressure state. In essence, the compressor performs four vital functions:

●      Heat Transfer

●      Turns warm liquid into a cool refrigerant

●      Absorbs heat to continue to transfer cycle

The Condenser

The condenser converts an element from gas to a liquid form. It is designed to aid in transferring heat while releasing the heat in the gas. This removes the heat from the core of the unit. The condenser is a makeup of several coils that are covered in a radiator-like screen. The hot air travels through the coil and then escapes. Condensers can easily be custom-made to suit any type of AC design. Condensers are used in a wide variety of application but essentially perform the same function.

The Evaporator

The evaporator coil is located inside the AC unit near the blower fan. Coils are engineered from copper, aluminum, or steel. These metals conduct heat in an efficient manner. The evaporator is made of panels that are referred to as fins. The fins cool the air as it passes through. The evaporator is the final stop in the cooling process. Once the condenser cools the liquid it turns into gas form due to low pressure coming from the evaporator.

Expansion Valve

The expansion valve regulates the amount of liquid refrigerant that comes into the evaporator. It does this by utilizing a temperature-sensing bulb. The expansion valve is the most important component in a heat pump because it generates the system’s ability to condition the air.

Muffler

Air conditioners are like engines. They are extremely loud when turned on. This is due to the noise made by the compressor and other components such as the fan motor. A muffler is installed to reduce the sound. It reduces the noise by allowing the gas to inflate inside the muffler’s cavity. The muffler’s dampers smooth out the sound frequencies in the both high and low range.
