To prevent the unnecessary loading of an air conditioning system while maintaining the designed dry bulb temperature and relative humidity in an air conditioning system, what should be done?
AI Explanation
The correct answer is D) admit only enough fresh outside air to provide proper ventilation.
Admitting only the necessary amount of fresh outside air is the best way to prevent the unnecessary loading of an air conditioning system while maintaining the desired dry bulb temperature and relative humidity. This approach ensures that the system is not overworked by introducing excessive outside air that requires additional cooling or dehumidification. The other options, such as continuously operating the purge recovery unit (A), reducing the air reheating system load (B), or lowering the compressor head pressure (C), are not as effective in optimizing the system's performance for the given conditions.
