Question 48Refrigeration & AC - 1st Asst/Chief

The correct answer is A) plenum chamber. The plenum chamber is the name given to the chamber or space in an air conditioning system where the ductwork originates. This is the main air distribution chamber that collects the air from the cooling or heating source and distributes it through the ductwork to the various rooms or spaces in the building. The other options are incorrect because: B) vapor chamber is not a standard term used in air conditioning systems, C) exhaust chamber refers to the area where the used air is expelled from the system, and D) intake chamber refers to the area where fresh air is drawn into the system, not where the ductwork originates.
