heat pump system design course development
TRANSCRIPT
Innovation in Higher Level Skills
Context
• GeoAtlantic Project• Supports deep geothermal
and ground source heat pumps in the Atlantic Region of Europe
• Includes training• IHLS Project• Focused on higher level
(level 4 to 7) training• Renewable energy on of
UoE themes
Innovation in Higher Level Skills
Heat pumps in UK
• Market growing well
• Training available for simple domestic installations
• Lack of higher level system design training
• Mistakes witnessed on small and large projects
Poor design examples
REEF building example• Client proposal for GSHP• M&E Engineers appointed
unable to correctly specify HP and ground array• Oversized unit• Heat loss wrong• Energy efficiency
options not included• Sized ground array on
peak heat demand only
Domestic examples
Retrofit Domestic
• Client keen for heat pump
• Air source suggested but required 3 phase upgrade
• Energy efficiency not explored
• GSHP possible at single phase
Course outline
• Heat loss calculations
• Heat pump options
• System design
• Heat distribution options
Heat loss calculations
• Correct sizing of heat pump
• Evaluation of energy efficiency options
• e.g. Insulation or MVHR
• Peak demand and annual energy demand
Heat pumps
• How a heat pump works
• Impact of source or distribution temperature on CoP
• Heat source options
Ground array design• Boreholes
• Sizing
• Geology and aquifer considerations
• Deep vs Shallow borehole options
• Shallow options
• Slinkies or straight pipe
• Sizing
• Energy piles
Hydraulic design
• Fluid mechanics principles
• Options for header and borehole arrangements
• Pipe sizing
• Pipe specification
• Pump specification
Water source
• Closed loop
• Open loop
• Heat exchanger specification
• Seawater options
• Environmental impact assessment
Full System design
• Heat distribution options
• Radiator, UFH, air blowers
• Hot water system integration
• Storage volume
• Managing legionella
• Sensors
• Integration of thermal storage
Heat distribution
• Performance implications
• Radiators
• UFH
• Warm air blowers
• Flow and return temps
• New build and retrofit
Integration with other technologies• Solar Thermal
• Biomass boiler / wood stoves
• Safety system options
• Gas boiler
• Ground loop implications
• Temperature options
• Metering
Scale
• Individual homes
• Multiple properties
• District heating options
• Central plant
• Distributed networks
• Large industrial buildings
Control
• Cost / Carbon saving / RE integration
• Smart control
• Individual pump control
• Multiple properties
• Battery integration
Design guides
• Use MCS as framework
• Apply to larger projects
• Provide tools to ensure design process is understood
• Design optimised for cost and performance
Accreditation
• Engaging with UK based GSHPA, HPA, CIBSE, MCS
• No clear pathway to accredit the course
