1. Multi-pipe Systems “An Opportunity To Combine Heating and Cooling”
EU ASE Press Conference,
Brussels, 17.October 2016
Presenter: Ronald Herpst

2. EU Primary Energy Use from 1990
BAU = Business As Usual
ECO = projected Ecodesign impact
HVAC in buildings
Source: Van Holsteijn en Kemna – Ecodesign Impact Assessment 2014
Challenge: Substantial Reduction of Primary Energy Use
for Space Heating

3. European Buildings and Energy Use
Building sector represents 50% of EU's annual energy use
Accounts for 13% of oil consumption
Accounts for 59% of total gas consumption
Causal reasons?
European buildings are old
Half of EU buildings have boilers from before 1992
22% of gas boilers and 47% of oil boilers older than technical lifetime
Renovation rate of existing buildings ~1%
Renewables not widely used
Natural gas = largest primary energy source
for heating and cooling (46%), followed by coal (~15%), oil (~10%), etc…
Renewable energy use has significant potential to increase share
Energy waste
Significant potential to regain and repurpose

Key Role for Heating & Cooling to Meet Energy Efficiency
and Renewable Energy Targets

4. Simplified Seasonal Energy Profile
Boilers and Chillers Running at Same Time = Wasting Energy
Energy Recovery = Best Form of Energy Saving

5. Energy and CO2 Reduction
Energy performance of buildings
Renewable energy deployment
Decarbonize - Primary energy use
Heat pumps or
Multi-pipe units
and/or
Solution: Combine heating and cooling
Applicable in most countries and climates
Improve efficiencies with low-medium temperature heating systems

6. Up to full energy recovery and use of renewables
No technology gap – Multi-pipe systems in non-residential buildings is reality ! (see booklet, page 11)
Multi-pipe units – EU innovation, manufactured in EU factories, ready for export
Sustainability
Up to full energy recovery and use of renewables
“Best return for every kWh of electricity used”
Cost Effective – Short Payback
“Best return for every kWh of electricity paid for”
Need Building Regulations To Scale Up Energy Recovery and Repurposing Solutions

8. Operating Principle

9. Summary of Operating Principle
Heating & Cooling demand at same time
Operating modes:
Chiller
Heat Pump
Chiller + Heat Recovery
100% COOLING
0% HEATING
0% COOLING
100% HEATING
Condenser only disposes of heat
Evaporator not utilized
Separate HX for hot water
Condenser & evaporator fully utilized for cooling/heating needs
Simultaneous heating and cooling
Differently from traditional heat pumps there are 2 separate heat exchangers for chilled and hot water production
Available sizes: 50 – 880 kW (heat pump mode)

10. Operating Mode: Chiller
100% COOLING
0% HEATING
CONDENSER (CR) NOT WORKING

11. Operating Mode: Heat Pump
0% COOLING
100% HEATING
EVAPORATOR (EV) NOT WORKING
Full Use of Renewable Energy

12. Mode: Chiller + Total Heat Recovery
100% COOLING
100% HEATING
COILS (BA) & FANS NOT WORKING
Full Regain and Repurposing of Energy = 100% Free of Charge Heating

15. European Buildings and Energy Use
Entire building sector represents 50% of EU's annual energy use
Accounts for 13% of oil consumption and 59% of total EU gas consumption
Includes residential/commercial/industrial buildings
Causal reasons?
European buildings are old
Half of EU buildings have boilers from before 1992
22% of gas boilers, 47% of oil boilers and 58% of coal boilers are older than their technical lifetime
Renovation rate of existing buildings ~1%
Renewables not widely used
Natural gas = largest primary energy source
for heating and cooling (46%), followed by coal (~15%), oil (~10%), etc…
Renewable energy use has significant potential to increase share
Energy waste
Significant potential to regain and reuse
