Design and experimental study of a cold storage type aircraft ground air conditioning vehicle
In order to reduce terminal carbon emissions,airports will gradually reduce the use of diesel power generation and cooling equipment.Design a cold storage aircraft ground air conditioning vehicle with an air supply temperature of 15 ℃,an air supply volume of 2 750 m3/h,and an air supply pres-sure of 45 kPa,and conduct experiments.The system uses 6 ℃ phase change cold storage materials,with a designed refrigeration load of 45 kW and a cold storage capacity of 18.3 kW·h,which can meet the cooling demand of 80 kW.The experimental results show that the maximum cooling load of the cold storage aircraft ground air conditioning vehicle in a short period of time reaches 105 kW,meeting the cooling needs of the aircraft's onboard electronic equipments.The cold storage type air-craft ground air conditioning vehicle stores the cooling capacity in the phase change cold storage mod-ule during the intermittent cooling period,releases the cooling during the cooling period,evenly dis-tributes some of the cooling load during the airport cooling period to the intermittent period,reduces the overall electrical load during the airport cooling period,and effectively reduces the cost of airport circuit laying and distribution transformation.
