The invention relates to a reheating method (500) for operating a refrigeration device (10) for a motor vehicle, the refrigeration device (10) comprising: a refrigerant compressor (12) which is or can be connected to a primary branch (14) and a secondary branch (16); an external heat exchanger (18) arranged in the primary branch (14); an evaporator (22) arranged in the primary branch (14); a heating condenser (26) arranged in the secondary branch (16); at least one movable temperature control valve (34L, 34R), which is arranged between the evaporator (22) and the heating condenser (26) with respect to the flow direction (L) of the inlet air wind; at least one shut-off valve (AE4, A1; r3, R4) arranged in the secondary branch (16) downstream of the heating condenser (26); wherein the reheating method comprises the following steps: connecting the at least one shut-off valve (AE4, A1; r1, R2, R3, R4) are adjusted into a position in which the refrigerant flows downstream of the heating condenser (26) into the evaporator (22) while bypassing the external heat exchanger (18), and at least one further heat sink, which is arranged in parallel or in series with the evaporator (22) in terms of flow technology, is connected, in particular, a water chiller (28) working as a water heat pump and/or an external heat exchanger (18) working as an air heat pump evaporator is connected. The invention further relates to a refrigeration device (10) and to a motor vehicle having such a refrigeration device.

    本发明涉及一种用于运行用于机动车的制冷设备(10)的再加热方法(500),其中,所述制冷设备(10)包括:制冷剂压缩机(12),其与初级支路(14)和次级支路(16)连接或能连接;外部热交换器(18),其布置在初级支路(14)中;蒸发器(22),其布置在初级支路(14)中;加热冷凝器(26),其布置在次级支路(16)中;至少一个可运动的调温阀(34L、34R),其关于送入空气风流动方向(L)布置在蒸发器(22)与加热冷凝器(26)之间;至少一个截止阀(AE4、A1;R3、R4),其在加热冷凝器(26)的下游布置在次级支路(16)中;其中,所述再加热方法包括以下步骤:将所述至少一个截止阀(AE4、A1;R3、R4)调节到如下位置中,在该位置中制冷剂在加热冷凝器(26)的下游在绕过外部热交换器(18)的情况下流入蒸发器(22)中,和接入在流动技术上与蒸发器(22)并联或串联布置的至少一个另外的热阱,特别是接入作为水热泵工作的冷水机(28)和/或作为空气热泵蒸发器工作的外部热交换器(18)。此外,本发明还涉及一种制冷设备(10)和一种具有这种制冷设备的机动车。
