Study on the Delayed-opening of Vacuum Pump in the Vacuum Pre-cooling Process
ince VCE-15 vacuum pre-cooling machine can be influenced by the air conditions in the vacuum chamber,the opening-time of vacuum is delayed,resulting in the prolonging of cooling period.Based on the cooling load,the computational formula for delayed-opening time was deduced,and verified by the experi...
