Discussion on four aspects of Misunderstanding analysis of“dry coil”

Discusses the problem of how to judge the dry operating mode of a fan coil unit by observation method in experiment. Restates the validity and reliability of cooling capability correction method of fan coil units based on the dry bulb temperature efficiency. Analyses the need for fresh air reheating in a dry coil system, and puts forward that a rational fresh air reheating method should be used in order to reduce the system energy consumption. Discusses the control method to avoid condensation in “dry coil”.
