冷凝温度变化对两相射流泵供液平板速冻机的影响
The effects of condensing temperature changes on plate freezer with two-phase ejector
摘要
Abstract
The working performance of plate freezer with two-phase e-jector in different condensing temperature was investigated in this study.Moreover,the effects of condensing temperature on freezing rate and total energy consumption of plate freezer was also studied. Then the entrainment coefficient in stable conditions and explores the effects on Jet pumps were analyzed by changing the condensing tem-perature.The results showed that when the condensing temperature was 25 ℃,the ejecting coefficient was the highest about 1 .58.Com-pared with 40 ℃and 30 ℃,the energy consumption was lowered by about 3.3% and 10% at 25 ℃,and the freezing time was shorten by about 12.5% and 1 7.5%,respectively.关键词
