Next Generation Ventilation (’NeGeV’)

NeGeV will develop:
-­ A PCM-based energy storage module (climate module) with novel heat exchange design and
integrated booster function
-­ Advanced integrated controls using complex algorithms to forecast and optimize operation, based on a
wide range of data on building latency, outdoor temperature, use patterns etc., making it possible to use
building latency, free cooling and the PCM module in combination to optimize energy efficiency and
reduce PCM-­ capacity needs.
Climate module development will be based on an initial mathematical modelling of the energy flow in the
building and HVAC-­system (Heating, Ventilation, and Air Conditioning), to be used for selection of PCM
materials, encapsulation and the sizing and design of the climate module, aided by accurate prediction of
the thermal behavior and performance of the phase change material.
Thermal and mechanical design of the PCM module heat exchanger will be analyzed in virtual simulations,
making it possible to test the efficiency of different systems designs and the performance of different PCMs
under realistic use regimens. Data from the simulations will be used in developing algorithms for the climate
module and AHU controller.
Development of advanced algorithms and integrated control systems will be based on the latest research in
building energy systems and Smart Grid integration. A HVAC prototype integrating the developed
components and technology will be developed, and tested in situ to validate and document performance.
The NeGeV project will provide HVAC-­customers with an extremely energy efficient HVAC system and the
possibility of earnings from demand response events through Smart Grid integration. The project will
significantly strengthen Exhausto’s market position and deliver the technological basis of an ambitious
growth strategy.
