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 […]
