| 摘要 |
<p>The invention relates to a method for cooling and warming purposes comprising 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 (3) of which comprises an element (13) situated in the space which is to be cooled or warmed. The invention is achieved by the two secondary circuits (3,4) being 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.</p> |
