Abstract
For air handling unit with large cooling capacity,some problems often occur during transitional seasons,such as low-pressure alarms,compressor oil return,evaporator frosting,etc.There are limited research achievements regarding the control of direct evaporative air handling units with large enthalpy differences.Taking the operational conditions of a project unit as an example,this paper analyzes the causes of low-pressure alarms and compressor oil level alarms encountered during the engineering application of large enthalpy difference screw compressor direct evaporative air handling units.It investigates and optimizes their control logic,which has been verified and implemented in engineering projects,significantly enhancing the operational reliability and stability of the air handling units.On-site operational validation results demonstrate that the control strategies and logic optimization proposed in this study are reasonable and meet the operational requirements of large enthalpy difference air conditioning units during transitional seasons.关键词
