AdRef-Noa consists of two identical adsorption /
desorption heat exchanging sections, one for each
evaporative and condensing heat exchanger.
Adsorption-desorption process, described below, is
interchanged and repeated in these two sections.
ADSORPTION
Water as a refrigerant evaporates in the evaporative
heat exchange section. AdRef produces chilled
water by using evaporative latent heat. The vapor is
then adsorbed by an adsorber A. The adsorber
generates heat, but removing this heat by cooling
water further enhances the evaporating process.
DESORPTION
Hot water (the heat source) is used to desorb the
moisture that is adsorbed in the adsorber B. The
released moisture enters the condensing section
and is condensed for next evaporation.
Adsorption Chiller
Friendly to mankind and to the earth -------AdRef-Noa
The more advanced AdRef-Noa makes the best use of unutilized heat source and
renewable energy including solar heat.
Adsorbent : Zeolite is utilized instead of Silica gel.
