- Compressor and Condenser: The compressor is the key component of the air conditioning system. It compresses the refrigerant gas, increasing its temperature and pressure. The high-pressure gas then flows into the condenser coil, where it releases heat to the outside air, causing the refrigerant to condense back into a liquid state.
Understanding how an air conditioner works helps you appreciate the intricate processes involved in maintaining a comfortable indoor environment.
Main components of an air conditioner
How do the main components of an air conditioner work together to cool and circulate air?
The main components of an air conditioner are the evaporator coil, expansion valve, condenser coil, and air handler.
A split AC system is commonly used for cooling residential and commercial spaces.
The evaporator coil, located inside the indoor unit, absorbs heat from the surrounding air and cools it down.
The expansion valve regulates the flow of refrigerant, allowing it to expand and cool further.
The condenser coil, located outside the building, releases the heat absorbed by the evaporator coil.
Then the air handler circulates the cool air throughout the room using a blower fan.
This process is repeated continuously to maintain a comfortable indoor temperature.
Working principle of a split type air conditioner
The working principle of a split type air conditioner is based on a simple and efficient process. Split air conditioning systems consist of two main components: the outdoor unit and the indoor unit. These components work together seamlessly to provide effective cooling and temperature control in residential and commercial spaces.
The outdoor unit is where all the action happens. It houses the compressor, condenser coil, and a fan. The compressor plays a crucial role in pumping refrigerant gas to the condenser coil. Once there, the refrigerant releases heat and condenses into a high-pressure liquid. The fan helps to expel hot air from the outdoor unit, ensuring efficient cooling.
On the other hand, the indoor unit is responsible for circulating cool air into the room. It contains the evaporator coil and a fan. The high-pressure liquid refrigerant flows through the evaporator coil, absorbing heat from the surrounding air and evaporating into a low-pressure gas. The fan then blows this cool air into the room, creating a comfortable environment.
To connect the indoor and outdoor units, refrigerant tubes are used. These tubes facilitate the heat exchange process. While the indoor unit produces cold air, the refrigerant absorbs heat from the room. This heat is then released outside through the outdoor unit, ensuring that the room stays cool and comfortable.
