What is the primary purpose of an air conditioning system?

• A. To increase humidity in the indoor air
• B. To maintain a constant temperature
• C. To circulate air throughout the building
• D. To remove heat and humidity from the indoor air

Answer: (D)

The primary purpose of an air conditioning system is to remove heat and humidity from the indoor air. This process is essential for creating a comfortable living and working environment, especially in warm and humid conditions. Air conditioning systems work by taking warm air from the indoor space, passing it through evaporator coils where a refrigerant absorbs the heat, and then blowing the cooled air back into the area. Additionally, as the air cools, moisture from the air condenses on the coils, effectively reducing humidity levels. This dual action of cooling the air and dehumidifying it is what makes air conditioning systems effective in providing comfort. Maintaining a constant temperature, while an important aspect of air conditioning, is actually a result of the system's primary function to remove heat. Similarly, circulating air throughout the building is a function of some systems, but it is not the main goal of air conditioning. Increasing humidity goes against the fundamental purpose of air conditioning systems, as they are designed to reduce humidity to improve comfort.
