What is conduction?

Conduction refers to the process of heat transfer that occurs through direct contact between materials. When two objects of different temperatures come into contact, heat energy is transferred from the hotter object to the cooler one until thermal equilibrium is reached. This process is essential for understanding how heat moves within solid materials, as it relies on the vibration and movement of atoms and molecules in direct contact with each other.

In the context of HVAC, understanding conduction is vital, as it affects the efficiency of heating and cooling systems. For example, heat losses or gains through walls, floors, and ceilings in a building can significantly impact overall energy efficiency. Recognizing the importance of conduction can aid technicians in selecting appropriate materials and insulation methods to minimize unnecessary heat transfer and enhance energy conservation in HVAC systems.
