Follow up:

Detailed description of topics:

·         Heat exchangers: formulas for heat and water vapour transfer on wet surfaces, dimensioning of whole or partly wet heat exchangers and apparatus for combined heat and water transfer, such as cooling towers, temperature efficiency of counter flow, parallel flow and cross flow heat exchangers.

·         Fans: pressure increase and other fan curves for different fan types, rules in connection with dimensions and number of revolutions, possible problems, energy efficient control of pressure level.

·         Noise: calculation of noise level of fans via the duct system, provisions for noise reduction, noise production in the ducts, noise transmission between two rooms via the duct.

·         Air cleaning and dust extraction: filter qualities and test methods for filters, building and installation of clean rooms and operating theaters, methods for gas cleaning.

·         Indoor environment control in industrial and recreational rooms: basic principles of air supply and exhaust.

·         Control of air conditioning installations: description of control system consisting of climate, building, AC-installation, parts of the control installation such as measuring instruments, controller and control devices, control of the system, building automation.

Remarks (specific information about assesment, entry requirements, etc.):

Goals:
In Indoor Climate Control B specific subject of the design proces are more fundamentally considered, such as dimensioning of heat exchangers, calculation of noise level, optimal control of the AC-installation.

Computer use:
The optimal and most energy saving control of an AC-installation is investigated with the program ENERK.

Laboratory project(s):
Demonstration of measuring devices by measurements in a climate test room.

Design content:
Components of HVAC

Percentage of design: 70% dedicated to design of components
