Abstract (en)
[origin: WO2023052244A1] The invention relates to a device for controlling the temperature of a space (5) to be temperature-controlled, the space having a space boundary (20) that separates the space to be temperature-controlled from the surroundings (21), the device comprising: a primary heat pump circuit having an evaporator (4), a condenser (2), a compressor (1) and an expansion element (3), the primary heat pump circuit having a natural, e.g. flammable, primary working fluid, and the evaporator (4), the condenser (2), the compressor (1) and the expansion element (3) being located outside the space to be temperature-controlled; and a secondary circuit, which is thermally coupled to the evaporator (4) or to the condenser (2) via a heat exchanger (7) and is fluidically decoupled and has a temperature-control element (14), which is located in the space (5) to be temperature-controlled and is connected to the heat exchanger (7) via a line arrangement (15a, 15b) that has a secondary fluid differing from the primary working fluid, the line arrangement (15a, 15b) penetrating the space boundary (20).
