Which term describes the method of controlling the temperature of a system by technology based on thermodynamics and heat transfer?

• A. The method of controlling the temperature of a system by technology based on thermodynamics and heat transfer.
• B. Ventilation
• C. Thermal Management
• D. PPE

Answer: (C)

Thermal management is the practice of keeping a system’s temperature within desired limits by using technologies that rely on thermodynamics and heat transfer. It covers removing excess heat with cooling methods—refrigerants, heat exchangers, condensers, fans, and control systems that adjust these components—as well as adding heat when needed to maintain a target temperature. The idea is to direct heat flow to or from the equipment so it stays safe and operates reliably. This is especially crucial for flammable-refrigerant refrigeration systems, where overheating can raise pressures and create hazards. Ventilation moves air for air quality and general temperature comfort but doesn’t manage a specific system’s temperature through heat transfer principles. PPE is protective gear and not about temperature control. So the term that best describes the method is thermal management.
