The invention provides an aircraft ground air-conditioning system. The aircraft ground air-conditioning system comprises a first heat exchange unit, a second heat exchange unit and a third heat exchange unit. In the first heat exchange unit, water in a water circulation system performs first-stage heat exchange with air in a first air flow channel in a first heat exchange body and then is delivered to a second air flow channel; in the second heat exchange unit, after a heat exchange medium of a heat exchange medium supply system exchanges heat with a refrigerant in a first refrigerant supply system in a second heat exchange body, the refrigerant flows into a second refrigerant supply system; in the third heat exchange unit, the refrigerant in the second refrigerant supply system performs second-stage heat exchange with air in a third heat exchange body; and the air subjected to two-time heat exchange is delivered to a cabin of an aircraft to adjust the cabin temperature. In order to meet the temperature requirement of the second-stage heat exchange of the air in the third heat exchange unit, the second heat exchange unit is used for adjusting and controlling the temperature of therefrigerant when the refrigerant enters the second heat exchange unit, and the second heat exchange unit is matched with the third heat exchange unit for use to improve cooling efficiency.

    本发明提供了一种飞机地面空调系统,包括:第一换热单元、第二换热单元和第三换热单元,在第一换热单元,水循环系统的水与第一空气流动通道的空气在第一换热本体内一级换热,随后输送到第二空气流动通道;在第二换热单元中,换热介质供给系统的换热介质与第一制冷剂供给系统的制冷剂在第二换热本体内换热之后,制冷剂流入第二制冷剂供给系统;在第三换热单元中,第二制冷剂供给系统的制冷剂与空气在第三换热本体内二级换热;经两次换热的空气输送到飞机的机舱,以调节机舱温度。本发明为了满足第三换热单元中空气二级换热的温度需要,利用第二换热单元调控制冷剂进入第二换热单元时的温度,第二换热单元与第三换热单元配合使用,提高制冷效率。
