How does an air conditioner work?

If you live in a condition with extreme temperatures, air conditioning is one of your most important home appliances that will improve your life and make everything appear more comfortable and relaxing. The Energy Information Administration signals that around 87% of households across America have some form of air conditioning, which underlines the dependency on air conditioners that have permeated modern life. But how does air conditioning work?

Here at Best of Machinery we have put together all the information you need to know about your air conditioner to give you a full understanding. An air conditioner works according to a basic concept based on a chemical called a refrigerant and sometimes called a chlorofluorocarbon or HCFC. The refrigerant flows continuously from inside your home to outside your home and banishes the heat outside your home. The refrigerant cools down when it gets into your home and the process starts all over again.

The air conditioning process in detail

When water is heated, the liquid evaporates to water vapor or gas. In this way, the refrigerant chemical works by absorbing heat in the liquid state and then converting it to gas. The refrigerant is then quickly converted back into a liquid and the previously absorbed heat is released to the outside. This cycle continues in an endless loop.

Parts of the air conditioner

The air conditioner consists of four parts: an evaporator, a compressor, a condenser and an expansion device. The evaporator is the part of the air conditioning system that is located in the house and evaporates the refrigerant chemical. Air flows to the evaporator, the refrigerant in the coil absorbs the air heat and converts the liquid into a gas. When this process takes place and heat is extracted from the air, the cold liquid turns into a hot vapor. The air is then cooled.

Once the refrigerant has evaporated, the gas visits the compressor section of the air conditioner, which is located outside the house on the air conditioner. The compressor compresses the gas to produce a higher pressure and temperature and directs this gas to the condenser. The condenser condenses the gas back to its original liquid state and radiates the heat. The cooled liquid then returns to the house. The fourth part of the air conditioner is the expansion device, which then regulates the flow of liquid refrigerant into the evaporator, and the process starts over.

Additional benefits

Air conditioning is a fantastic tool to control the temperature in your home and cool your family when the higher temperatures occur. However, there are additional benefits that your home can take advantage of once you’ve fully installed air conditioning.

Air conditioning also reduces humidity and reduces the amount of water vapor in the air, which makes your body feel cooler when sweating is reduced. This dehumidifying effect allows the air to be both drier and cooler, increasing comfort in your home. It is interesting to note that moisture control was in fact the primary objective of the very first air conditioners invented by Wills Carrier in Brooklyn, NY in 1902. Temperature control was an additional benefit for air conditioning at that time, which ironically became the main selling point for modern air conditioning.

In fact, the term “air conditioning” was not used until four years later in 1906, when the first residential air conditioning system was installed in 1914. This air conditioner was 7 feet high and 6 feet wide. and an enormous 20 feet long. Of course, this technology was only available to the rich in 1914. Air conditioners cost between $ 10,000 and $ 50,000, which is equivalent to a payment between $ 120,000 and $ 600,000 today.

Environmental influences

To maintain an environmentally conscious attitude, it is wiser to buy the newer air conditioners. International treaty agreements such as the Montreal Protocol have ensured that the chemical composition of the refrigerant compounds is much more environmentally friendly. Older air conditioners use refrigerant formulas that use chlorine atoms, which can potentially damage the ozone layer. Fortunately, these compounds have been slowly being phased out for use with air conditioning.

The Montreal Protocol was launched in 1987 and explained the importance of climate protection and the substances that deplete the ozone layer. The refrigerants used in modern air conditioning comply with the new regulations and allow you to cool your home so that the ozone layer is not damaged. These changes in the refrigerants used in air conditioning systems have undoubtedly contributed significantly to reducing global production, consumption and emissions of ODS or ozone depleting substances.
