Adsorption Chiller

Operating principle

Standard specifications Performance for ADR-Z4520

Outer Dimensions

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.

ADSORPTIONWater 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.

DESORPTIONHot 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.

Adsorbent : Zeolite is utilized instead of Silica gel.
