HVACCEC-180005
Syllabus for course Refrigeration Fundamentals
Course is for both Master and Journeyman
Instructor: Bruce R Waters
Course objectives
Introduce the participants to the vapor compression system and how it works
Introduce the participants to the thermodynamics involved in the refrigeration cycle
Introduce the participants to the three class of refrigerants and some of their chartists
Introduce the participants to the enthalpy curves Charles's, Boyle's and Dalton's laws
Course topics:
System Difference with vapor compression system
Thermodynamics temperature absolute zero, energy the BTU methods of heat movement
Changes of state latent heat of fusion, vaporization and sublimation specific heat, sensible heat
concepts of saturation sub cooling superheating saturation temperature Gage pressure relationship to absolute pressure
the gas law general, specific volume, density, fluid head, Laminar flow the various refrigerants function , the cycle the refrigerant goes thought terms used due pint bubble pint temperature glide fractionation pure fluids
The different refrigerants and replacement that are approved bow water now becomes very
important
refrigerant enthalpy curves Charles, Boyles and DaLtons laws
how compressor and their efficiency and other operation points effect system efficiency
how compound system can provided temperatures of -200 deg f and below
Class is 8 Hours credit.
The course is design to increase the awareness of attendees of the necessity of proper component sizing as well as the way the system is installed. It gives them a understanding of that goes in to a refrigeration cycle and how complex the cycle is.
