HVACs are becoming increasingly popular in controlling the air quality. There are two types of HVACs systems and they can be either single or multi-stage systems. The single stage heating and cooling is popular because you get to keep warm and cool depending on the climate outside.
Air conditioning was an invention that made practically anywhere in the world a viable place to live and do business. This invention was made for homes and other buildings such as places of businesses and factories before it was then built in a suitable way to ensure they could fit and operate in your car. While the AC system may seem complex there are a few parts you can learn about and fix by yourself.
The AC is comprised of a system whose main fluid is Freon. The Freon is pressurized by the compressor and thus becomes hotter because it usually absorbs the heat around. The hot gas is taken to various parts where it loses the heat. The cooler the Freon becomes it changes state from gas to liquid. From this cool liquid cold air is blown to your surroundings. Recent studies have now shown that Freon R-12 is harmful and causes depletion of the ozone layer and therefore led to the invention of R-134a which even though is less efficient is not causing environmental harm. Your technician can organize the replacement of your AC refrigerant to the eco-friendly R-134a.
There are many installation types such as the window air conditioner, the split systems, the mini split system and the largest type of installation which is the central air conditioner.
Most air conditioners have the following similar parts, the compressor, the condenser, the evaporator, the expansion valve and the drier or accumulator. These parts are interconnected using pipes and valves. Refrigerant is the fluid which is also highly volatile that transports heat from one component to another. The air conditioner basically starts working when you turn on the AC and the refrigerant goes to the compressor where it is compressed and absorbs heat and changes from liquid to gas. Then it goes to the condenser where it is cooled sometimes in some systems the condenser may be fitted with an electric fan. After being cooled and changing back to liquid the refrigerant moves to the evaporator where it is cooled further and then air is blown across it for it to become cool and this cool air is then blown into your environment. The refrigerant then absorbs the heat from the air blown and it reverts to a gas. The drier removes any impurities on the refrigerant using filters and desiccant to absorb any moisture. The expansion valve controls how cool the air you receive will be. Then the process takes place over and over until the room is cooled. This is also referred to as the refrigerative cycle. Before acquiring a unit you should check how energy efficient it is and for some of the appliances industries they offer free installation of your unit.
