A room humidistat initiates the lowering of the humidity of the conditioned supply air to a space, while the actual process is accomplished by what means?

Alowering the cooling coil temperature and raising the reheater temperature
Braising both the cooling coil temperature and the reheater temperature
Clowering both the cooling coil temperature and the reheater temperature
Draising the cooling coil temperature and lowering the reheater temperature
AI Explanation

You are correct, the answer A) lowering the cooling coil temperature and raising the reheater temperature is the correct answer. The correct answer is A because lowering the cooling coil temperature will reduce the temperature of the air entering the space, which in turn will lower the humidity. Raising the reheater temperature will then reheat the air to the desired temperature, maintaining the appropriate conditions in the space. The other options are incorrect because they do not properly describe the process of lowering the humidity in the conditioned air. Raising both temperatures (B) or lowering both temperatures (C) would not effectively lower the humidity. Raising the cooling coil temperature and lowering the reheater temperature (D) would not achieve the desired humidity reduction.
