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

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

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 Source: EU Commission Fact Sheet, February 2016 Key Role for Heating & Cooling to Meet Energy Efficiency and Renewable Energy Targets

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

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

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

Operating Principle

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)

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

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

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
