Later in the afternoon high temperatures will increase head pressure and the resulting overcharge means a lower than desired superheat and wasted energy. Not good! Overall Process: • Enter refrigerant, temps, and pressures • The math is done for you to display Superheat, Subcooling and Airflow Target, Actual, and Difference • Email all readings (detail) Other Features: • Flexible units - psi, kPa, Fahrenheit, Celsius, etc. • Calculates Superheat and Subcooling targets • Airflow - For cooling, compares a targeted difference across the coil vs. actual. Also called Delta-T or Target Evaporator Exit Temperature (TEET). • System Status Report - Use the email tab to create defaults for email addresses, subject, and System Status Report introductory text. Tap the email button and these values are incorporated into a formatted page including all the parameters recorded in HVAC Buddy. Edit the email and / or add contacts from your contact list.
