IMR 4090 - Refrigerant Recovery Technique
Clock Hours: 50
Delivery Mode on-ground
Course Description: Students learn the principles of the refrigeration cycle and its components functions along with the ability to identify various refrigerants and the oils associated with them. Students will learn each components function and the state of matter of the refrigerant corresponding to its pressure group. Students will be introduced to the refrigerant classifications and their chemical compositions effect on the environment. Students will be introduced to refrigerant safe handling practices and how to effectively recover refrigerants within the guidelines of the law.
