The Book
Refrigerant Charging and Service Procedures for Air Conditioning
This book is dedicated to those who are eager to learn the HVACR Trade and Refrigerant Charging/ Troubleshooting Practices. In this book, you will find Step by Step Procedures for preparing an air conditioning and heat pump system for refrigerant, reading the manifold gauge set, measuring the refrigerant charge level, and troubleshooting problems with the system’s refrigerant flow. This book differs from others as it gives key insights into each procedure along with tool use from a technician’s perspective, in language that the technician can understand.
This book explains the refrigeration cycle of air conditioners and heat pumps, refrigerant properties, heat transfer, the components included in the system, the roles of each component, airflow requirements, and common problems.
Procedures Included:
·Pump Down
·Vacuum and Standing Vacuum
Test
·Recovery and Recovery Bottle use
·Refrigerant Manifold Gauge Set
and Hose Connections
·Service Valve Positions and Port
Access
·Preparation of the System for
Refrigerant
·Refrigerant Charging and
Recovery on an Active System
·Troubleshooting the Refrigerant

The Cards
These three UPDATED HVAC quick reference polystyrene cards are double sided and
designed to be used with Air Conditioners and Heat Pumps to measure the refrigerant charge
level in a unit, charge refrigerant, troubleshoot refrigerant based problems, and measure heat
transfer to determine if there is a problem.
-
Use the P/T Chart to find the Saturated Temperature of the common refrigerants R-32, R454B, R-410A, R-22, R-407C, R-422B, and R-438A.
-
Use the Guide to determine how to find the Bubble and Dew Saturated Temps of Blend Refrigerants.
-
Use the Refrigerant Weight Chart to calculate the amount of refrigerant needed per foot of tubing R-32, R454B, R-410A, R-22, R-407C, R-422B, and R-438A.
-
Use the Guide to weigh in the full or partial refrigerant charge into an empty vacuumed unit.
-
Find the Target Subcooling to measure the refrigerant level of systems with a TXV metering device.
-
Use Subcooling to determine if a system is undercharged, correctly charged, or overcharged.
-
Use Delta T to determine if the system is exchanging heat properly.
-
Find the Target Superheat to measure the refrigerant level of systems with a fixed orifice metering device.
-
Use Total Superheat to determine if a system is undercharged, correctly charged, or overcharged.
