Research project
Climate-neutral cooling with the sun in Cuba
In this project, an air conditioning system is being developed for tropical, humid climate regions that can both cool and dehumidify rooms. A compressor refrigeration machine is used, which is fed directly from a solar system.
The aim of this project is to develop and establish an air conditioning system that both cools and dehumidifies rooms and can also operate completely autonomously and independently of electricity grids, which are often prone to faults. To this end, the cooling compressor is to be supplied with the necessary drive energy by a PV battery system.Cooling is then provided by a water-based capillary cooling system with an intermediate cooling water storage tank.
Once an initial pilot system has been set up in Switzerland, the components will be successively coordinated and converted in line with the envisaged low-tech/low-cost approach. A system will then be set up within the University of Havana in order to make the final climatic adjustments and to be able to conduct the first training courses. Another system will then be tested in a real tropical environment. At the same time, the first installation companies will be found and a financing model tailored to Cuba will be developed.
