Air conditioning is one of the most common appliances in the world. It’s used to cool homes and businesses in the summer, and to heat them in the winter. How does it work?
The most common type of air conditioning unit is the central air conditioning unit. This type of unit cools or warms the air in your entire home. It does this by sucking in hot or cold air from outside, and then blowing that air across a series of coils. The coils are filled with a refrigerant, which changes state from a gas to a liquid as it passes through the coils.
The liquid refrigerant is then pumped into a compressor, which increases its pressure. The high-pressure liquid is then forced through a small hole into an expansion valve. This valve reduces the pressure of the refrigerant, which causes it to turn into a gas again. The gas is then blown across the coils, which turns it back into a liquid. As the liquid refrigerant passes through the coils, it absorbs heat from the air.
The cooled or warmed air is then blown back into your home through ducts. The refrigerant continues to cycle through the system, absorbing heat from the air and cooling or heating your home as needed.
Air conditioning is a process of removing heat and humidity from the air. The most common type of air conditioning unit uses a refrigerant to remove heat from the air. The refrigerant is compressed and then enters a condenser coil, where it releases heat to the outside air. The refrigerant is then allowed to expand and enters an evaporator coil, where it absorbs heat from the air. The refrigerant then returns to the compressor, where the cycle begins again.
