PRICE:   $240.00

TARGET AUDIENCE:

Facility operation personnel, technicians and management who are required to maintain refrigeration systems for air conditioning and who have a basic knowledge of refrigeration principles.

 

COURSE DESCRIPTION: 

After an overview of a typical refrigeration cycle, there is a discussion on how various problems impact the operation and pressures in the refrigeration system.  The changes to the trade resulting from EPA regulations are covered, including refrigerant phase-out and their typical replacements, working with blends and R-410A, service procedures to meet the new regulations, procedures for using the new refrigerants and oils, and the new machine room requirements.  Typical service procedures are covered, including using the manifold gauges, T-P chart, leak detection, seasonal startup, pumping the system down, refrigerant recovery, pressurizing the system, evacuation and adding refrigerant.

 

LENGTH OF COURSE:       1 Day

 

TRAINING PREREQUISITES:  Some previous training on refrigeration fundamentals
