Air conditioners play a crucial role in keeping our indoor environments comfortable and cool, especially during hot summer months. To understand how an air conditioner functions, it’s important to explore the primary parts that contribute to its operation. We at Air Supply Heating & Air Conditioning would like to discuss the key components of an air conditioner and their functions today.
Main Air Conditioning Components
1) Compressor: The compressor serves as the heart of an air conditioner. It is responsible for circulating refrigerant throughout the system, compressing it into a high-pressure, high-temperature gas. By compressing the refrigerant, the compressor increases its energy and prepares it for the next stages of the cooling process.
2) Condenser: The condenser is a heat exchanger located outside the building. It receives the high-pressure, high-temperature refrigerant gas from the compressor and facilitates its transition into a liquid state. As the refrigerant condenses, it releases heat to the surrounding environment, thereby cooling down and preparing for further cooling.
3) Evaporator: The evaporator is another heat exchanger, typically located inside the building, often connected to the furnace or air handler. Its primary function is to absorb heat from the indoor air. The liquid refrigerant enters the evaporator, and as warm air from the building passes over the evaporator coil, the refrigerant evaporates, absorbing heat from the air.
4) Expansion Valve: The expansion valve controls the flow of the refrigerant between the high-pressure side and the low-pressure side of the air conditioner. It is a small, metering device that allows a controlled amount of refrigerant to pass through, causing the refrigerant to expand and cool down further. This expansion of the refrigerant helps to regulate the temperature in the evaporator coil.
5) Fan: Air conditioners utilize fans to circulate air within the system. There are two main fans in an air conditioner: the indoor blower fan and the outdoor fan. The blower fan, located in the indoor unit, blows air over the evaporator coil, facilitating heat exchange and cooling the indoor air. The outdoor fan, situated in the condenser unit, expels heat from the condenser coil, helping to maintain the proper functioning of the system.
6) Air Filter: Air filters are vital components of air conditioners. They are responsible for capturing dust, debris, and other particulate matter present in the indoor air. By preventing these contaminants from entering the system, filters help maintain the air conditioner’s efficiency, enhance indoor air quality, and protect the other components from damage.
7) Thermostat: The thermostat acts as the control center for the air conditioner. It allows users to set the desired temperature and regulates the cooling process accordingly. When the temperature in the room exceeds the set point, the thermostat signals the air conditioner to start cooling. Once the desired temperature is reached, the thermostat signals the system to turn off.
