How Does an Air Conditioner Work?


Air conditioning is a term used to describe heat removal from the air; this can also mean the purification of air as it passes through the device.

Many individuals don’t really know how an air conditioner functions or how to manage it, including those who have air-conditioned. This article will detail everything you need to know about the air conditioning system’s components and provide you with some tips on how to keep it optimal.

The standard air conditioning consists of the following components:

  • The compressor.
  • The evaporator coil often referred to as the inner coil.
  • A capacitor coil sometimes referred to as the outer coil.

Like a car radiator, the coils execute functions. The coils serve as conductors for the temperature of the outside air.

Air conditioners are an essential device for homes, industrial companies, jet engines, the refinery industry, the manufacturing industry, and the automobile industry. Air compressors have been used in industry for over a century. It is a portable system used to supply a particular space with compressed air and power. It is used for all purposes that need more power or a small amount of air.

They are available in various kinds that are manufactured to meet different needs. Air conditioners are differed in terms of the cooling mode, degree of compression, power supply, and lubrication.

Three Major Types Of Air Compressors Exist:

Reciprocating Compressor (Piston): With this type, to store compressed air and reservoirs, a piston is used. This form can be one or two passes, depending on the number of compression passes. In compressed air, one piston is used in one stage, while two pistons are used for air compression in two stages.

Rotary Air Compressor: This is the Same as the positive reciprocal compressor setting. Two rotating spiral screws instead of pistons are used in this form. Air is compressed and forced into the tank as the screws rotate towards one another.

Centrifugal Compressor: Also referred to as a dynamic compressor, it is ideal when compressed air is greatly needed. The high-speed impeller increases the airspeed with this form, which is intended for a diffuser that converts the air velocity into electricity. To run, this compressor takes more energy than two compressors.

Two key components make up the unit: a compression mechanism and a power supply. A rotary piston, blade, or wheel may be the compression unit, while the power comes from an electric motor or other power sources. The compression mechanism helps to compress energy from the energy source into the ambient air.

How Does An Air Conditioner Work

The compression of ambient air that is used as required is the basic principle of the operation of an air compressor. Atmospheric air enters through the intake valve during travel; more air is automatically drawn into the enclosure by the piston, spatula or wheel. The pressure immediately increases as the volume of extracted ambient air is applied to the tank. Stated, after a reduction in volume and an increase in power during the same time, ambient or free air is compressed. There are handles for power adjustment that can be used according to the operator’s needs.

The button interrupts the air inlet on the compressor by configuring the maximum power of the tank or receiver. The pressure level drops when compressed air is used. The power button will glow when energy drops to the low pressure in an environment, allowing air to reach the atmosphere. The series in the air compressor, therefore, continues.

How it works

As a customer, the core elements of the air conditioner system must be recognized and, first of all, the five main functional components of air conditioning must be identified and how they operate together:

Compressor – Conversion Key To Refrigerant

This is also called the “heart” or “driver” of your air conditioner, functioning as a pump within your machine. Outside the device, which is called a condenser, the compressor is mounted. The compressor starts to suck low-temperature, low-pressure gaseous refrigerant from the system after the thermostat activates the system. Until being discharged into the condenser coil, the gas is then compressed to a higher pressure and temperature.

Condenser – Capacitor Coil

Often found in the outdoor unit or device is the capacitor coil. It is made up of a series of tubes containing thousands of small fins. After the compressor has stopped, refrigerants pass through this coil. Using the fins for full heat dissipation, the fan pulls air through the coil to remove heat from the coolant. Until entering the expansion valve, this process causes the refrigerant to become liquid under high pressure.

Expansion Valve – The Refrigerant Regulator Mechanical Part

This vital part of the system has to monitor the conversion and the amount of refrigerant that passes through the evaporator. Usually, it is found in the system. Liquid refrigerant seeps through a tiny opening in the valve under high pressure, causing a pressure drop as it passes. The refrigerant spreads to a liquid/vapor mixture at this stage that can join the evaporator coil.

Evaporator – Indoor Coil

The evaporator is a series of tubes that produce another coil through which the liquid/vapor refrigerant passes through and absorbs heat from the air that passes through it. This decreases the air temperature that is then transmitted into your home through your ducts, reducing the room temperature. As the refrigerant returns to the compressor, the cycle continues so that the air on your thermostat in your home is set to the desired temperature.  Be sure to always seek great services like Sun City Air Conditioning for help with anything complex.

Blower – Internal Fan

A blower is a fan which draws heat air into the return line through an air filter. It moves air through the evaporator’s coil to disperse it across the house through ducts.

Air conditioning also helps regulate the moisture in your home by humidifying and dehumidifying, in addition to cooling your home. Some systems have a boiler for moisture collection that extracts moisture from the air, while the refrigerant absorbs heat.

There are several models, and sizes of air conditioners, but they all operate the same way. Air conditioners expel heat from the building instead of letting fresh air into the house. They use chemicals, called refrigerants, that can be converted from liquid to gas rapidly and efficiently.


The liquid refrigerant that has been cooled is then returned to the evaporator jacket. The phase is starting all over again. This cycle is repeated until the air temperature in the house reaches the target temperature, which is typically set by the owner of the house when the thermostat connected to the air conditioner selects a particular temperature.
