| 摘要 |
An apparatus for heating an operating fluid, the apparatus comprising a closed circuit (18) for a working fluid, the closed circuit (18) having first (10) and second (20) heat exchangers and a compressor (22) therebetween, the first heat exchanger (10) having a heat input side (34) for connection to an external fluid heat source and a heat output side (24) for vaporising working fluid within the closed circuit, the compressor (22) being a vapour compressor adapted to compress the vaporised gaseous working fluid from the first heat exchanger (10) to form a higher pressure gaseous working fluid, and the second heat exchanger (20) having a heat input side (26) for receiving and condensing the higher pressure gaseous working fluid from the compressor and a heat output side (30) for heating an external operating fluid. A corresponding method is also disclosed. |
