Renewable Cooling – On the way to large market introduction Teun Bokhoven, Director Conergy Business Development & Export Vice President ESTIF

AC Market is the fastest growing market in building services. Increasing comfort demands AC Demand in EU 1990-2020: Factor 5 Grid breakdown risks– Blackout AC causes increasing CO2 Emissions x 3 x 5 Source: Energy Efficiency and Certification of Central Air Conditioners (EECCAC) study for the Commission of the E.U.

Solar Assisted Air Conditioning- market implementation starts Single houses | Small 10kW cooling solution | Cooling at night (internal chem. storage) | Re-cooling with pool | Combined with floor cooling | Heat pump in winter Clients „Early birds” Upmarket segment High comfort demand Commercial applications 35-200kW cooling power Plug & Play Container Solution (10-40 feet) Trivalent usage (Cooling/Heating/DHW) Combined with back up – 24/7 Clients Offices Shopping centres Hotels

Economics- Solar Assisted Cooling will pay off. Price indication investment depends on project semi-standardised solutions higher investment costs will be balanced by lower energy cost

Our world is full of energy.
