ABSTRACT
The aim of this project funded by the European Commission is the following one: determine low electric consumption cooling systems well adapted for photovoltaic and for application in developing countries. Two different systems were intended: evaporative air-cooler, buried pipe system. The efficiencies in sensible heat, quite high for these systems (6 to 10) in application with 220VAC, have been optimised for photovoltaic. The tests showed that these coefficients could exceed values of 20. The innovative aspect of the studied systems are: ∎ low consumption motor for fans ∎ adapted fan for different systems ∎ range of device defined in order to provide cooling power necessary for premises from an office to a little shop ∎ cooling "along with the sun"
