Learning outcome

KNOWLEDGE
Provide the student with knowledge about:
- Brief introduction to heating systems based on biomass, solar heat, district heating, natural gas and heat pumps
- Thermodynamics for the heat pump cycle incl. analysis of different heat pump cycles in T-s, T-h and p-h charts.
- Thermodynamic, practical and environmental properties for working fluids.
- Main components – compressors, heat exchangers (evaporators, condensers etc.), expansion devices etc. in heat pumps.
- Heat sources and heat source systems incl. seawater, ground water, bedrock, soil, ambient air, ventilation air, grey water and sewage.
- Power and energy demand for heating and cooling of buildings.
- Dimensioning, design/construction and control of heat pump plants.
- Heating/ventilation systems and how they affect performance and energy use for heat pumps.
- Hands-on experience with heat pump design.
- Investment and profitability analysis.

SKILLS
The course should enable the student to:
- Carry out exergy calculations for different heating systems incl. heat pumps.
- Calculate heating/cooling capacity, COP and seasonal performance factor (SPF) for single-stage and two-stage heat pump systems.
- Design heat pump systems on a principle level, i.e. not detailed design of components.
- Understand the operating dynamics in heat pumps are different operating conditions with regard to heating/cooling capacity, COP and different operation parameters.
- Work out system optimum designs for heat pump systems with regard to thermodynamic principles and practical issues.
- Carry out investment analysis and profitability analysis for heat pump systems.

GENERAL COMPETENCE
The course should give the student insight on:
- Environmental impact and primary energy use for system for heating/cooling of buildings.
- Principles for thermodynamic heating.
- System approach, the relationship between components (subsystems) and efficiencies.
- Optimal integration of heat pumps in buildings with heating and cooling demands.
- The most important factors that have an impact on the energy use of heat pump plants.
