Basics of Refrigeration

In our previous HVAC Journal entries, we reviewed the fundamental concepts surrounding heat, pressure, matter, and energy as they pertained to their functional roles in the HVAC/R industry. Now, we will be delving into how these conceptual laws are integrated into the day-to-day operation of what we do as technicians in the field. Let’s begin wit [...]

Basics of Matter and Energy

Previously, we reviewed some salient fundamentals that are essential to understanding how things work in the HVAC/R industry, and why they work the way they do. Piggybacking off this topic, there are other rudimentary elements in play that are vital to conceptualizing the "how's and why's" as well; however, this topic is more focused on the "what" [...]

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 [...]

The Cost of Overlooking Routine Maintenance

One of the most commonly overlooked aspects in the HVACR industry is the routine maintenance of refrigeration units. This is often overshadowed by talk of the importance of maintaining A/C units. The prevalent perception that is held towards cleaning dirty coils is that "nobody does it" and is therefore a waste of time and ignored. We have seen o [...]
