Discussion on Energy Efficiency Grades of Evaporative Cooling Air Conditioning Equipment

Abstract

In this paper, problems and inconvenience of existing parameters which are used to describe the energy efficiency of the evaporative cooling equipment were discussed. In accordance with the principle of the psychrometric chart, different energy efficiency grades of the evaporative cooling equipment were analyzed. On this as is, 5 energy efficiency grades for evaporative cooling equipment were put forward, combined with the psychrometric chart. In addition, the process and reasonableness of the grading were introduced.
