EMFE2700 Electrical Engineering and Building Automation Course description

Tekniske installasjoner i bygninger er avhengig av elektrisitet og automatikk for optimal funksjon og emnet tar sikte på å gi studenten en grunnleggende innføring i dette. Innen automasjon finner man blant annet direkte digitale kontrollere (DDC) som ved hjelp av programvare og bus-systemer styrer komponenter i VVS-anlegget. Det finnes et utall teknikker som kan knytte sammen funksjoner mellom systemer for å lage bedre styring, overvåking eller nye fellesfunksjoner i et teknisk anlegg og disse teknikker betegnes Integrerte Tekniske Bygningsinstallasjoner (ITB).

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

The student:

• can apply the no-slip condition
• can classify flows and describe laminar and turbulent flows
• can calculate hydrostatic pressure in liquids and corresponding forces on surfaces and buoyancy
• familiar with different methods of pressure measurement
• can visualize a flow field
• can use the continuity equation (conservation of mass)
• is able to use Bernoulli's equation, equation for conservation of mechanical energy
• can calculate forces associated with flow systems
• can analyze flow in pipes, channels, networks. Calculate energy and pressure losses
• can measure flow rates and quantities (mass flow, volume flow)
• can calculate resistance forces (tensile forces) by external flow (flow along surfaces and around bodies)
• can calculate conditions associated with turbomachinery such as pumps and fans

Skills

The student is able to:

• perform necessary calculations for engineering analysis of fluid engineering problems in practical constructions, including piping systems in buildings and in the rest of nature
• calculate pressure drop through a pipe or duct system and then calculate the required pump or fan power
• calculate forces acting between a fluid at rest and a wall, in order to dimension suspension
• calculate forces acting between a fluid flow and the pipe wall, in order to dimension suspension
• calculate how long it takes to empty a tank
• dimension a simple network of pipes/ducts (e.g. radiator system)
• measure flow rates and volume and mass flow
• calculate flow resistance for solid bodies moving relative to a fluid
• choose the right size of pump in a pipe system

General competence

The student is able to:

• contribute to the development of new technology based on an understanding of mathematical modeling and the solution of physical problems
• solve coupled problems related to both fluid mechanics, heat and mass transport and thermodynamics
• assess whether calculation results are reasonable and the validity of the mathematical model

Lectures, class discussions, exercises and laboratory exercises in groups.

The following coursework is compulsory and must be approved before the student can sit the exam:

• 2 lab assignments in groups

Individual written exam, 3 hours

The exam result can be appealed.

A resit or rescheduled exam may take the form of an oral exam. If oral exams are used for resit and rescheduled exams, the result cannot be appealed.

All printed and written aids, as well as a calculator.

Grade scale A-F.

One internal examiner. External examiners are used regularly.
