Synopsis

The module describes air conditioning in the context of psychrometry and psychrometric processes. It discusses physiological principles that govern the health and comfort requirements of humans in an air conditioned environment. It also explains the fundamentals of basic air conditioning systems, their application and performance objectives. It further gives an overview of refrigeration systems with emphasis on refrigeration system components & processes. It concludes with the effect of solar heat gain and incident rays orientation in improving the energy efficiency of building.

Outcomes

On completion of the module, students will be expected to be able to:

1Understand psychrometric processes
2Perform cooling and heat load calculations in buildings
3Apply basic principles of air conditioning systems
4Develop adequate procedures in the analysis of refrigeration cycles
5Understand the fundamentals of heating and refrigeration processes
6Understanding the effectiveness of incident rays in air conditioning design
7Utilising solar heat gain to improve the energy efficiency of buildings

Assessment

Coursework assessment: 25%
Examination: 75%

Workload requirements

Refrigeration & air conditioning in commercial and industrial buildings is an important part of building infrastructure development. This module is dedicated to equipping the students with the analytical and design capabilities required to provide environment that is comfortable to humans working inside the building infrastructure. There will be a combination of lectures, that will include interactive elements. All outcomes will be assessed by means class tests and a final examination.
