How Air Conditioning Works
Air conditioning systems make it more comfortable to live in your home by removing heat and reducing the risk for heat stroke, dehydration or other health conditions.
An air conditioner uses phase conversion to change the refrigerant from a liquid to a gas. It then pumps this heat-absorbing, refrigerant outside using an evaporator coil.
Compressor
Your compressor is the core of your cooling system. It moves refrigerant back and forth between your evaporator, condenser, and evaporator coils.
Compressors come with gasoline, diesel and electric motors. The gasoline-driven models are usually best for small projects around the house or in the workshop. Diesel engines tend to power larger outdoor compressors.
A piston within a compressed moves up and downwards in its cylinder. This piston draws in warm gases of refrigerant, while its downstroke decreases volume.
Some compressors employ a single stage compression cycle. Others use two stages. They can generate higher pressures, and cool the air entering their first cylinders.
No matter which compressor you have, it's important to keep it in good shape. A dirty air compressor can cause mechanical failure, reducing efficiency. To avoid this happening, inspect coils and ductwork periodically for dirtiness.
Condenser
Condensers are an essential part of any air conditioning system. They convert high pressure refrigerant into liquid, then return it to your system so that you can keep your home cool.
The coils of the condenser are typically made out of copper. These coils come with metal fins and fans to dissipate heat as they pass through, discharging it while doing its job.
Once the refrigerant is in the compressor, it's compressed even more to try and get it back to liquid state. Desuperheating occurs when multiple passes through a compressor are made to cool the refrigerant down to its saturation temperature.
If you suspect that your condenser has been damaged or is malfunctioning, it's vital to have a professional inspect and assess the unit immediately. Early intervention could save money by preventing the unit's shutdown.
Evaporator
Modern air conditioning systems heavily rely on their evaporator component. These two parts work together to remove heat, carry it through the system, and release outside.
The evaporator cylinders in your air conditioner are made of copper tubing which conducts the heat efficiently. The coils are located close to your blower fan so that they can function efficiently.
As warm atmosphere passes over an evaporator's coil, its refrigerant absorbs that heat and changes from liquid to vapor, dissipating heat into the surrounding air and cooling it.
If your refrigerant absorbs too little heat, it will not turn into vapor. This will cause your air conditioner to not function as intended. Pinhole leaks may also occur, and your air conditioner's evaporator should be kept free of dust for optimal performance.
Ductwork
The ductwork of air conditioning systems is essential. Without it, the temperature in your home could be lower than you would like and the conditioned HVAC system air could escape.
There are several types of HVAC ductwork, each with its own advantages and drawbacks.
Flexible ductwork has a tendency to be less expensive and simpler to install compared to rigid ducts. However flexible ducts may have bends and twists which can reduce efficiency due to airflow restrictions.
Rigid ductwork has a higher temperature resistance and is more durable. It can also be made from different materials such as fiberglass.
Ductwork is connected directly to HVAC systems' supply and return Plenums where air-conditioned, heated air that flows through ductwork can be stored before being released.
