    • An air treatment device (1 ) and a method for heating of air in a heating mode at an air handling unit (2), which comprises a heat recovery device (3). The device further comprises a heat pump (6), comprising an evaporator (7) arranged in a first air stream (4), in the flow direction after the heat recovery device (3), and a condenser (8) arranged in a second air stream (5), in the flow direction after the heat recovery device (3). The device further comprises an auxiliary heater (9) for supplying external heat energy, in addition to the recovered energy. The invention is characterized by that the auxiliary heater (9) is positioned in the first air stream (4), in the flow direction after the heat recovery device (3) and before the evaporator (7) for heating, and thereby the heat pump (6) operation is maintained and a better total efficiency for the plant is achieved.
    • 空气处理装置(1)和用于前后加热的方法,在加热模式下,在在空气处理单元(2),它包括一个热回收器(3)。 该装置还包括一热泵(6)包括蒸发器(7),在流动方向上的第一空气流(4)布置,所以热回收器(3),和冷凝器(8)之后排列成 在流动方向上的第二空气流(5),所述热回收装置(3)之后。 该装置的辅助加热器(9),用于供给,除了回收的能量,来自外部的热能的进一步包括。 辅助加热器(9)在第一空气流中被定位(4)在流动方向上,热回收设备(3)之后和所述蒸发器(7),用于加热并由此热泵(6)的操作被保持前 并为植物更好的总效率的实现。
