Energy cogeneration is a way to improve global efficiency
of energy production systems since it consumes a unique
resource in order to supply heat and electrical power through
optimal use of heat fluxes associated to power production.
Energy trigeneration enlarges the concept to the production of
cold also. It consumes a unique resource to produce electricity,
heat and cold. Nevertheless, we could go more ahead by
substituting a part of the primary fuel resource by renewable
energy as solar energy in order to reduce the carbon impact.
This is conducted through the use of adsorption refrigeration
which needs hot water to produce cold water. However, even if
energy utilities are provided with the best efficient way, the
final use of energy could make all the efforts fall. Cooling
ceilings present one of the best solutions to be coupled to solar
cooling since it needs a medium range cold temperature of the
fluid in order to avoid condensation if the wall ceiling
temperature drops below the ambient air dew point
temperature. All these constraints need to be checked
experimentally and confronted to numerical simulation. For this
purpose, an experimental platform has been developed
combining an internal combustion gas engine (cogenerator), a
refrigerating adsorption machine, thermal solar collectors and
wooden construction split in two compartment, a cold one
conditioned by cooling ceilings and a hot one conditioned by
heating floors. The platform is completely instrumented. In this
paper we focus only on the refrigeration machine for which we
developed a simulation model that is confronted to
experimental measurements.
