B. P-H Diagram (Pressure vs Enthalpy)
C. P-V Diagram (Pressure vs Volume)
D. Effect Of SST & SCT On Capacity
E. Effect Of Subcooling & Superheat On Capacity
F. Effect Of Pressure Drops
G. Capacity Control Methods
Purpose: To understand what the basic components & control schemes of a mechanical refrigeration system are and how they work together.
2. Refrigerant Piping <10 hours>
A. Primary Considerations
B. Procedure
C. Tables for Suction, Discharge & Liquid Line Selections
D. Example Problem For Typical Suction Line
E. Double Riser Application
Purpose: This a very practical, step-by-step procedure that prepares the student to design future refrigerant piping systems as well as trouble-shoot existing systems for problems that cause ineffective operation or even premature failure of the compressor.
3. Refrigerants & Our Environment <2 hours>
A. History of CFCs
B. Montreal Protocol
C. Current Legislation
D. The Future Of Mechanical Refrigeration
Purpose: The 1987 Montreal Protocol changed our industry in a most significant way. This talk helps you to fully understand where we have come and where we are heading in regards to the transition from CFCs.
