Learning outcomes
After successful completion of the course, students are able to...
understand and describe the most common applications and functions of chillers and heat pumps,
read and understand state diagrams for ideal gases and the usual refrigerants,
apply the first and second law of thermodynamics to a chiller system and calculate the occurring energies / energy flows and entropies / entropy flows,
identify the most frequent cycles in the technical field and calculate occurring thermodynamic quantities,
describe the various thermodynamic cycles for generating "cold" in the chillers and "heat" in the heat pumps from mechanical energy or heat and calculate the EES or COP,
sizing recooling units and estimate the "performance" of anergy sources for the heat pumps,
describe the function of compressors, heat exchangers, piping, and fittings in the refrigeration circuits,
describe the most common applications and requirements for refrigeration systems and heat pumps (air conditioning, food preservation, heating systems, etc.).
Subject of course
Description of the thermodynamic cycles of refrigeration systems.
Discussion of cold steam engines (vapor-compression and absorption refrigeration cycle) and cold gas engines.
