REFRIGERATION FUNDAMENTALS

(2009 Session-2: February 10 - 12, 2009, Rochester, NY)

1. Basic Refrigeration <12 hours>

A.  Basic Components
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.
