Temperatures rise in many areas quite significantly in the summer. Thus, many people have home air conditioning. However, do we know how these units work? How do you think they work? Do they lower temperature in your homes by simply pumping cool air in? Nevertheless, this is not the real case.
What they do is that they removed warm air from your house and cycle back in cooler air. This cycle will continue until your thermostat reaches the desired temperature. It is like a refrigerator without the insulated box. It uses the evaporation of a refrigerant to provide cooling. Home air conditioning, similar to refrigerators, uses the mechanics of the Freon evaporation cycle.
First, the compressor compresses cool Freon gas, causing it to become hot, high-pressure Freon gas. Then this hot gas runs through a set of coils so it can dissipate its heat and it condenses into a liquid. The Freon liquid then runs through an expansion valve, and in the process, it evaporates to become cold, low-pressure gas. This cold gas will then run through a set of coils that allow the gas to absorb heat and cool down the air inside your home or building. Lightweight oil is also mixed with Freon to lubricate the compressor.
However, your home air conditioning system does not only help in keeping your home cool, they also help clean your home's air as well. Most products have filters that catch dust, pollen, mold spores and other allergens as well as smoke and everyday dirt found in the air. They also work as dehumidifiers. Excess water from the air is removed and used to help cool the unit before getting rid of the water through a hose outside. Other products use the condensed moisture to improve efficiency by routing the cooled water back into the system to be reused. This is the general concept involved in this type of system. With these devices, you not only have a cooler home, you will also have cleaner air in your homes! In addition, it does not work as simply as you think they should.
