The Components of Air Conditioning

Keeping your indoor air cool is a crucial function of Air Conditioning. In addition to providing ventilation and appropriate humidity levels for all areas of a building, air conditioning removes dust, soot, and other foreign bodies from the air. It also eliminates microorganisms from the air, and keeps the indoor temperature cool during the warmer seasons. In addition to being an important home and office comfort system, air conditioning also helps to save energy and lower your bills.


Refrigerants in air conditioning are substances that cool or heat the air. Historically, a variety of substances were used, but the choices of these substances have grown increasingly complex in recent years. For example, some of the older generation of refrigerants contributed to stratospheric ozone depletion, and are now phased out under an international treaty. Hydrofluorocarbons (HFCs) are a newer alternative. These compounds have a high global warming potential (GWP), and are subject to use restrictions in some countries. Newer, lower-GWP HFCs are being introduced into the market to replace these chemicals.

While most of us have no idea why refrigerants are harmful to the environment, they do have an important role in the cooling process. Some of the most common refrigerants are ozone-depleting and cause global Air Conditioning Installation Central Coast warming. To combat this, manufacturers are switching to more environmentally friendly alternatives, including R134a and R410a. These newer chemicals are less damaging to the environment and are abundant in the market.


The parts of an air conditioning system are classified by their construction and operating characteristics. Most of the components of air conditioning systems are electrical. The electrical components are essential for maintaining temperature and minimizing equipment operation costs. They can range from wiring to complex control system circuitry. Among the electrical components are capacitors, which absorb electricity from the main supply and keep a constant charge. A start capacitor kicks off the cooling process and a run capacitor keeps the motor running steadily during the cooling cycle.

The three main components of an air conditioner are the indoor fan motor, the compressor, and the evaporator coil. All of these pieces have varying ratings. The evaporator coil, sometimes called the cooling coil, is responsible for removing heat from the air indoors and returning it cool. The blower fan also controls air flow within the room. These components work in conjunction to create the optimal temperature and humidity conditions in any room.


Modern air conditioning systems are major energy users, increasing the running cost of the building by up to 50%. In many OECD countries, air conditioning is one of the largest contributors to the peak power demand, which can be costly for the utilities to serve. These devices are a prime target for energy-efficiency improvements. Fortunately, many measures have been developed to reduce the power consumption of air conditioners, making them more environmentally-friendly.

However, current room AC testing methodologies are insufficient for measuring energy efficiency. For example, they do not include tests in high humidity conditions, or reward partial load operation or the inherent benefits of variable speed compressors. Developing a new testing methodology would unlock additional savings from more energy-efficient designs. In addition, government agencies should update the MEPS floor and make the top tier of the energy-efficiency label higher. In the meantime, manufacturers should invest in research and development to improve their efficiency.


In the U.S., air conditioning makes up approximately 12 percent of the average energy bill. This cost varies widely depending on the rate you pay and where you live. In Texas, for instance, you’ll need more air conditioning than you will in Maine, and vice versa. For this reason, the cost of air conditioning varies significantly across states, ranging from only $60 per year in cooler climates to $525 per year in hot and humid areas. The national average cost of air conditioning is $265 per year.

The cost of air conditioning depends on the brand, type, size, and features of the system. Generally, a basic unit from a well-known brand will cost less than a less-popular brand. Other brands will cost more, but these systems will offer the highest level of comfort and energy efficiency. The cost of air conditioning varies from brand to brand, so make sure to shop around before you decide on which system is best for your home.
