IMR 4110 - Condensers & Evaporators


Clock Hours: 30

Delivery Mode
on-ground

Course Description:
Students learn the principles of various condensers and evaporators applications. Students will learn the typical operating conditions associated with condensers and evaporators. Various operating conditions will be addressed and identified as being normal or abnormal to indicate specific problems in the refrigeration cycle. Condenser and evaporator performance will be tested on various types of systems to determine capacity and efficiency. Proper maintenance procedures will be discussed and reviewed for the varying types of condensers and evaporators. Troubleshooting and evaluating techniques will be introduced to determine problem areas that may need to be addressed.
