Description:
This module provides an intro to the concept of refrigeration and discusses the most commonly usd refrigeration system, the vapor-compression refrigeration system, the relationship between the basic components of a vapor compression system, and also the heat pump cycle.
Thermodynamics States, Properties and Laws
Description:
This module introduces the concepts of thermodynamic states, properties, and laws, efficiency (coefficient of performance) and defines the maximum coefficient of performance for a heat pump and refrigeration cycles.
Psychrometrics
Description:
Psychrometrics is the field of engineering concerned with the physical and thermodynamic properties of gas-vapour mixtures.
Multi-Stage and Cascade Refrigeration Cycles
Description:
This mod will introduce the concepts of single and multi-stage refrigeration cycles, as well as cascade refrigeration cycles. It will also discuss the various methods for metering the refrigerant flow to the evaporators, including the direct expansion system, the flooded system and the recirculation system.
Refrigeration System Parameters and Performance
Description:
In this module, several refrigeration system performance parameters are defined. These parameters are useful for characterizing how well a particular system may be operating. Compressor performance is also discussed.
Refrigerants
Description:
This module provides an introduction to refrigerants, including selection, performance, safety, reliability, environmental impact, and economic viability.
