Heat and Pressure Fundamentals

One of the most fundamental principles that has an integral role in the HVAC/R industry is heat: what it is, how it is transferred, and its different forms. Heat is defined by the laws of thermodynamics. Temperature, which describes the level of heat with reference to no heat, is quantified by temperature which is related to heat content defined [...]
