CO_2 BASED COMPRESSION ADSORPTION HYBRID: A NOVEL HIGH PERFORMANCE REFRIGERATION AND AIR CONDITIONING DEVICE

摘要

A central challenge in cooling science today is the development of air conditioning and refrigeration systemrnthat is compact; virtually free of moving parts, highly reliable, free of toxic and environmentally-harmfulrnsubstances, high coefficient of performance (COP) and available at affordable price. In this study, we havernproposed a novel hybrid refrigeration and air conditioning system that symbiotically combines the processesrnof mechanical vapor compression and solid vapor adsorption, and uses carbon dioxide (CO_2) as thernrefrigerant. The proposed hybrid system uses functional activated carbon (type Maxsorb III) as thernadsorbent. It incorporates solely existing technologies. The present simulation results show that the proposedrnsystem can attain large cooling power at high COP, which is approximately two to three times higher thanrnthat of conventional CO_2 based vapor compression cycle. This proposed hybrid system is targeted for airconditioningrnapplications in automobiles and in building sectors.
