Fundamentals of Refrigeration: Heat Transfer

February 10th, 2026

The movement of heat is traditionally referred to as “heat transfer”. Thermodynamics is a term applied to the study of heat movement. The laws of thermodynamics are a crucial foundation for understanding heat movement. The first law of thermodynamics states that energy can be neither created nor destroyed, merely changed.  Since heat is a form […]

Fundamentals of Refrigeration: Latent Heat

January 27th, 2026

When a substance changes state from solid to liquid, or from liquid to vapor, it is said to undergo a phase change. Interestingly, as heat is applied or removed from a substance during a phase change, the temperature of the substance remains constant. For example, when a block of ice melts to form water, the […]
