HVAC Engineering

Historical development of heating, ventilation, air-conditioning and sanitation engineering (HVAC). The design process. Standards and norms. System solutions for renewable energy production and heat storage; for ventilation and tempering of rooms; for domestic water supply, sewerage and preparation of domestic hot water. Selection and sizing of systems for renewable energy production and heat storage; space heating and cooling. Natural ventilation, principles of air supply and tempering of rooms. Methods for selecting and sizing the supply air terminals. Sizing of hydronic heating systems. Selection of components for air conditioning; filters, dampers, fans, ducts, pumps, valves, pipes, heat exchangers, sensors and control components. Monitoring and control of air conditioning plants, building automation. Use of dynamic simulation program for the design and evaluation. Procedures for operation and maintenance.

KNOWLEDGE: The course provides the student with knowledge about: - background for requirements for zero energy and zero emission buildings and neighborhoods - background for requirement specifications for indoor air quality, energy supply and energy use - application of dynamic simulation software for design of energy supply and climate systems, and for evaluation of indoor environment and energy efficiency - system solutions for renewable energy production and heat storage - system solutions for ventilation and tempering of rooms - system solutions for domestic hot water supply, sewerage and preparation of domestic hot water - methods for sizing of ventilation, heating and cooling - principles of natural ventilation - methods for sizing of central heating systems - functional principles of components of air conditioning plants; filters, dampers, fans, ducts, pumps, valves, pipes, heat exchangers and control components - content of solutions for monitoring and control of air conditioning plants The course gives the student insight about: - historical development of heating, ventilation and sanitary engineering - legal framework and standards - design processes for buildings - methods for selection and sizing of supply air terminals - procedures for operation and maintenance SKILLS: The course will enable the student to: - analyze the required capacity for renewable energy supply and heat storage - analyze the required capacity for technical installations for ventilation, heating, cooling and domestic hot water - deliver descriptions of system solutions for renewable energy supply, heat storage, ventilation, tempering of rooms, domestic water supply, sewerage and the preparation of domestic hot water - use dynamic simulation programs for dimensioning of energy supply and air conditioning systems, and evaluation of indoor climate and energy efficiency - work independently and in interdisciplinary groups GENERAL COMPETENCE: After ended course: - should the student be able to apply the knowledge and the skills to analyze, select and design solutions for renewable energy supply, heat storage, technical installations for air conditioning, and the domestic water systems in buildings based on requirements for indoor environment and energy efficiency.

Lectures. Calculation and simulation exercises. Self-study. Site visits to study air conditioning plants in buildings. Problem-based collaborative learning, student groups solves a task regarding engineering design of a renewable energy supply and air conditioning for a single building. Assignment is mandatory; it must be approved to participate the final exam. Lecturing is provided in English when students who do not speak Norwegian take the course. If lectures are given in English, the examination text will be given in English only. The student's answers may be in Norwegian or English.
