Refrigeration

Refrigeration is the process of removing heat from a space or substance to lower its temperature. It’s crucial for preserving food, cooling equipment, and many industrial processes. Key Characteristics / Core Concepts Heat transfer: Refrigeration relies on the principles of heat transfer, moving thermal energy from a cold area to a warmer one. Refrigerant: A … Read more

Heat Transfer

Heat transfer is the movement of thermal energy from a region of higher temperature to a region of lower temperature. This process continues until thermal equilibrium is reached, meaning both regions have the same temperature. Key Characteristics / Core Concepts Temperature Difference: Heat transfer requires a temperature gradient (a difference in temperature). Thermal Energy: It’s … Read more
