Type of article: Article, Case study

Summary

Tests the operation parameters of evaporative cooling-mechanical refrigeration air conditioning unit of a data in Xi'an during transition season, and obtains the performance parameters including temperature, relative humidity, air volume and refrigerating capacity. The test results show that the efficiency of the indirect evaporative cooling is 58%, while that of the direct evaporative cooling and the indirect-direct two-stage evaporative cooling is 86% and 115%, respectively. The ratio of the cooling load by both fan and duct temperature increase to the total cooling load is up to 24. 28%, whose influence on total cooling load cannot be omitted.
