Résumé

Electrochemical compressor (ECC) can produce pressurized refrigerant through electrochemical reaction, and ion selective electrolytes. It can be an ideal replacement for mechanical compressor (MC) that have low compression efficiency and noise problem caused by driving parts. Considering the piston rotating at high speed about 25~30 RPS, it is very difficult to cool the incoming fluid and the gas pressure and temperature increase due to adiabatic compression. However, ECC is prone to lowering temperature of the discharge side as it does not have a driving part, and the surface area of membrane is wide. Therefore, since sufficient intercooling can be performed by attaching heat exchangers on multi-stage compression, an isothermal compression process can be achieved. It means, since it is not compressed by volume reduction, compression close to isothermal compression is possible. In this study, a performance of the isothermal compression refrigerator system using ECC is compared with the mechanical compression system. When cooling the ECC with outside air, adiabatic compression is implemented at the compression front-end and isothermal compression at the rear-end.
