Entropy
Entropy Explained
\n
As HVAC professionals, understanding the principles of thermodynamics is crucial to optimizing system performance and energy efficiency. One of the fundamental concepts in thermodynamics is entropy. In simple terms, entropy can be defined as the ratio of the heat added to a substance to the absolute temperature at which it is added. But what does this mean for our industry?

Understanding Entropy
\n
At its core, entropy is a measure of disorder or randomness in a system. In the context of HVAC, it helps us understand energy transfer and efficiency. When heat is added to a substance, it doesn't just increase the temperature; it also affects the arrangement and motion of the molecules within that substance. The higher the entropy, the more dispersed the energy and the less useful it becomes for doing work.
