Résumé

This study focused on a vertical open-type display cabinet with double air curtain, and investigated the effect of pre-cooler on
supply and return air of air curtain in display cabinet. The experimental investigation was undertaken in the test room with temperature of 25°C and relative humidity of 60%. The results showed that: the temperature of the supply air was not obviously elevated, and the return air temperature was reduced by 5°C ; the inner supply air and the return air relative humidity of air curtain changed little, the outer supply air relative humidity dropped from 69% to 60% ; and the enthalpy of outer supply air kept a fixed value, and the enthalpy of the return air decreased by 21.4%. The decreases of return air temperature and enthalpy could lead to significant decrease in the display cabinet load.
