Will the efficiency of a unit decrease if the sun shines directly on the panels and coils of the condensing section?

  1. A. Yes

  2. B. No

  3. C. It depends on the unit

  4. D. Efficiency will increase

The correct answer is: A. Yes

When the sun shines directly on the panels and coils of the condensing section, it can increase the temperature of the air surrounding the unit. As a result, the condenser will have a harder time releasing heat since the surrounding air is already warm. This extra heat can cause the unit to work harder to achieve the desired cooling effect, leading to a decrease in efficiency. Therefore, the correct answer is A.
