CT is the abbreviation for which HVAC component?

• A. Cooling Tower
• B. Condenser Tank
• C. Chilled Transformer
• D. Central Thermostat

Answer: (A)

In HVAC, CT stands for cooling tower, the device that rejects heat from the condenser water loop to the outdoors. In a typical water-cooled plant, the chiller’s condenser releases heat into circulating condenser water, which then flows to the cooling tower. The tower uses air flow and evaporation to lower the water temperature before it returns to the chiller, enabling efficient heat rejection and system operation.

The other terms don’t fit the common meaning of CT. A “condenser tank” isn’t a standard component in typical HVAC terminology, since the condenser is the heat exchanger where the refrigerant releases heat, not a tank. A “chilled transformer” isn’t a recognized HVAC device, and a “central thermostat” refers to a control device rather than a physical cooling component labeled on equipment.
