Module Overview

This module presents new subject matter on heat transfer and heat systems at masters level. Although many students will have studied thermodynamics material (i.e. basic refrigeration cycle and psychrometrics) at undergraduate level, the module is designed to cover more practical aspects of refrigeration and air conditioning system design and evaluation, as well as additional topics on heat transfer.

The module particularly addresses the latest development and application of alternative refrigerants for reducing the global warming impact of HVAC&R systems, as well as refrigeration component/system optimization.

Topics Covered

  • Thermal radiation heat transfer
  • Refrigeration systems operation and refrigerant selection
  • Characterization of refrigeration evaporators and condensers
  • Characterization of refrigeration compressors
  • Refrigeration system design and balancing
  • Introduction to heat transfer, 1-D conduction
  • Fins
  • Convection in external flows
  • Convection in internal flows
  • Heat exchangers – LMTD and NTU methods
  • Air-conditioning

Learning Outcomes

Upon completion of this module students will be able to:

  • Evaluate the thermal radiation heat transfer between surfaces, including thermal radiation shields.
  • Solve one-dimensional steady state conduction problems by applying the heat balance equation and using thermal resistances through linear, cylindrical and spherical geometries.
  • Determine the heat transfer occurring through a series of fins and their performance.
  • Analyse convection problems and determine convection coefficients in external flow conditions, flat plate, cylinder, tube bundles and in internal flow conditions, circular and concentric circular tubes.
  • Design and dimension a heat exchanger system both by using the notions acquired in the previous points and by applying the NTU method or the log mean temperature difference method.
  • Understand the operation of a vapour compression refrigeration system and how its operation and performance depend on various internal and ambient conditions.
  • Select appropriate refrigerant for a given application, characterize and choose suitable components to balance a refrigeration system according to certain design specifications.
  • Have a solid understanding of the Psychrometry of air conditioning processes and be able to choose optimum supply design conditions by using notions of sensible heat, latent heat and room ratio line.
