A method for cooling and warming: a refrigerant circuit (2) with at least a compressor (5), a liquid-cooled condenser (6), a liquid-heated evaporator (7) and two outer secondary liquid-based circuits (3,4). The first of those circuits includes (3) an element (13) situated in the space which is to be cooled or warmed, and which is operative for that purpose. The second circuit (4) includes a radiator operation to cool the liquid in the circuit. The two secondary circuits (3,4) are united, during heat pump operation, to form a common single circuit so that the condenser (6) heats liquid which is supplied to the element (13), with the result that the element (13) releases heat instead of cold, without the flows in the primary refrigerant circuit (2), in the element circuit (3) or in the radiator circuit (4) being alternated/reversed. A valve controlled bypass bypasses the radiator in that circuit. |
