    Abstract: An air treatment device (1) and a method for heating of aft, 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, in addition to the recovered energy, external heat energy. 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.

    Abstract translation: 一种空气处理装置(1)和用于在加热模式下在包括热回收装置(3)的空气处理单元(2)处加热后方法。 该装置还包括热泵(6),其包括在热回收装置(3)之后沿流动方向布置在第一气流(4)中的蒸发器(7),以及冷凝器(8) 在热回收装置(3)之后的第二气流(5)沿流动方向。 该装置还包括辅助加热器(9),用于除了回收的能量之外还提供外部热能。 辅助加热器(9)在热回收装置(3)之后并且在用于加热的蒸发器(7)之前在流动方向上位于第一气流(4)中,从而保持热泵(6)的运行 并实现了更好的总效率。

    Abstract: Method and device for defrosting of an evaporator (1) in a heat pump (2) connected to an air handling unit (9), which comprises a controllable heat recovery device (10). The heat pump (2) comprises a refrigerant system (3) with a refrigerant (4), a compressor (5), a condenser (6), a first expansion valve (7) and an evaporator (1). A four-way valve (8) is arranged after the compressor (5) and before the condenser (6), for changing a flow direction of the refrigerant (4) to the evaporator (1) instead of the condenser (6). The heat recovery device (10) recovers energy from first air stream (11) and transfer energy to second air stream (12). When frost formation occurs, the refrigerant temperature is increased and the recovery device (10) is regulated down so that heating of the evaporator (1) is accomplished, both from inside and outside to defrost the evaporator (1).
