Scientific/Technological quality and innovation
Need and Issues
1. Industrial: Obtain a new system for conditioning of buildings, that replaces the current air conditioning systems, moreover with better working conditions, with a lot of energy saved, more than 75%, and with null health risk.
2. Economic: Obtain a new system at lower installed cost with lower use of energy and at lower electrical power than the current air conditioning systems.
3. Social problem to overcome: Decrease the C02 and other greenhouse gases, reduce the heat rejected to the atmosphere, eliminate the aerial noise and reduce the legionella disease risk. Improving the acceptability of renewables.
The project addresses the saving of imported energy, the reduction of the electric energy pick, mainly in summer time, the reduction of the greenhouse gases by the use of the solar energy and the increase of renewable energy use.
The competing technology is the current air conditioning systems which have several limitations, the main are:
o Intensive use of electrical electricity yielding high cost and high CO2 enusslons.
o High power of electric network and a large number of new electric lines having an environmental impact.
o Bad working conditions that create the sick building syndrome: draught, odour, high inner contamination, thermal imbalance.
A significant step forward beyond the state-of-the-art
• New solar roof design, that catches the sun energy for heating, cooling, recovery of energy and in certain applications, it can replace the structural roof
• Total integration of room conditioning with sanitary hot water production. These claims represent a big step forward beyond the state of the art and save 75% of energy.
A critical appraisal of the level of technical risk and any relevant factors which may influence the chance of success
The only risk involved in the system could be the use of more auxiliary energy than the one postulated for the relevant equipment of the system, meaning higher electrical consumption or higher estimated cost with the risk to save less energy than the one predicted, but we believe that this risk is low.
