Résumé

Embedded Adsorption refrigeration technology has an advantage of providing efficient cooling with the heat supplied from the community energy supply system including the feed water of district heating system, industrial waste heat, and others. however, conventional adsorption refrigeration system shows a low COP. In this study, SAP(superabsorbent polymer) was coated on a heat exchanger by about 100 um thickness to enhance heat and mass transfer performance during adsorption and desorption processes. As the cycle time gets longer, the SCP decreases but the COP increases. COP was estimated to be 0.25 to 0.49 and SCP was 300 W/kg. As cooling water temperature supplied to the condenser and adsorber increase, the cooling capacity rate and COP decrease due to the deterioration of the desorption and absorption performance, respectively.
