What does adding a 500 TR chiller increase?

• A. Cooling load and condenser heat rejection
• B. Boiler fuel consumption
• C. Steam pressure
• D. Electrical power by a fixed amount

Answer: (A)

Adding a 500 ton refrigeration (TR) chiller raises the plant’s cooling capacity, which means more heat must be removed from the process — that is the cooling load increases by the same amount. All that heat the chiller extracts has to be rejected somewhere, and in a condenser, so the condenser duty also increases correspondingly. In short, you’re boosting both the cooling load and the heat that must be rejected by the condenser. Boiler fuel consumption isn’t directly driven by the addition of a chiller, so it doesn’t necessarily rise. Steam pressure is set by the steam system design and boiler operation, not by adding a chiller. Electrical power will go up due to the chiller’s power draw, but not by a fixed amount—the exact increase depends on the chiller’s efficiency (COP) and operating conditions.
