Refrigeration & Charging Procedures
Refrigerant pressures, states and conditions are
covered, as well as how they apply to the refrigeration system.
Vapor pressures, subcooling, superheat, saturation, latent heat, and
sensible heat are explained and applied to the refrigeration cycle.
Basic system components, their functions and applications are
included. Detailed explanations of each point in the refrigeration
cycle will clarify questions the reader may have.
Definitions and system applications of
subcooling and superheat are also included in this module. Condenser
subcooling, total subcooling, evaporator superheat and total
superheat are explained with examples as they apply to the basic
Friction and static pressure losses, with
examples and applications, gives the reader a thorough understanding
of how much subcooling is needed in any system.
Advanced topics such as; liquid pressure
amplification, superheat suppression, floating head pressure, and
refrigerant control systems are included.
This module includes a detailed explanation of
refrigerant metering devices which include; thermostatic expansion
valves, automatic expansion valves, and capillary tubes.
Application, sizing, and troubleshooting under varying system
operating conditions are explained.
System charging procedures as they apply to
these various types of air conditioning and/or refrigeration systems
are included. Charging charts and charging curves with examples of
system applications give the reader a thorough understanding of
system charging when reading this module.
