Course Description

HVAC refrigerant charging with subcooling course, in this course we will learn about HVAC refrigerant charging with subcooling, a precise method used to optimize the performance and efficiency of HVAC systems. The course will cover the fundamentals of refrigerant charging, focusing on the subcooling method, which is crucial for systems equipped with a thermal expansion valve (TXV). You will learn to measure and calculate the subcooling value, understand the importance of achieving the correct subcooling range, and how to add or remove refrigerant to maintain this range. The course includes step-by-step instructions on preparing the system, using tools like pressure gauges and thermometers, and safely handling refrigerants. We will also discuss troubleshooting common issues related to refrigerant levels and ensuring no leaks are present. Practical exercises and real-world scenarios will help solidify your understanding and skills. By the end of this course, you will be proficient in performing refrigerant charging with subcooling, ensuring your HVAC system runs efficiently, saving energy and reducing operational costs.
