What is the main distinction between a water-cooled and air-cooled condenser?

• A. One uses air and the other uses water
• B. One operates under high pressure and the other under low pressure
• C. One requires electricity and the other does not
• D. One is larger than the other

Answer: (A)

The main distinction between a water-cooled and air-cooled condenser lies in the method of heat exchange used to dissipate heat from the refrigerant. The correct answer emphasizes that a water-cooled condenser utilizes water as a cooling medium, while an air-cooled condenser relies on air for the same purpose. In a water-cooled condenser, water circulates through the condenser coils, absorbing heat from the refrigerant and then carrying it away. This type is often used in larger industrial applications due to its efficiency and ability to remove heat quickly. Conversely, an air-cooled condenser uses ambient air to cool the refrigerant, making it suitable for smaller systems or locations where water is scarce or expensive. The other choices might hint at differences between the two types of condensers, but they do not capture the fundamental operational distinction. Factors like pressure operation, electricity usage, or size can vary based on specific models and applications but are not defining characteristics of the two categories of condensers themselves. Thus, the core difference remains centered around the cooling medium—water versus air.
