Synopsis
This episode focuses on understanding and effectively utilizing various refrigeration system charts and measurements for troubleshooting and diagnostics. Joey Henderson, an HVAC veteran and trainer, shares his wealth of knowledge and experience on this topic. Joey starts by discussing the challenges he faced early in his career when trying to make sense of the confusing charts with arrows indicating high, low, high head, low head, etc. He emphasizes the importance of knowing the "supposed to be" values before attempting any measurements or referencing charts. Without this baseline understanding, the measurements become meaningless. He then delves into specific measurements like subcooling, superheat, evaporator temperature/suction saturation, condenser split, and compressor amperage. For each measurement, Joey explains the ideal range, how to interpret deviations, and how different factors like humidity, airflow, and refrigerant type can affect these values. He also highlights the differences in approaches fo
