能源是当今社会发展的三大支柱之一,是经济发展和社会进步的重要基础.近年来,由于人类对能源的需求越来越大,能源供应成为社会经济发展的瓶颈.在能源消耗不断攀升从而带来诸多社会和环境问题的现实背景下,节能减排已成为当今人类的共识.本文依次介绍了机械蒸汽再压缩热泵技术、空气能热泵技术、喷气增焓技术三种节能技术.充分利用低品位能在一定程度上具有节能的效果,由此,基于有机朗肯循环及卡琳娜循环两种动力循环,介绍了低品位能两种利用技术:低品位能借助正循环(有机朗肯循环或卡琳娜循环)热功转换实现发电及低品位能借助正循环热功转换实现制冷.

Energy is one of the pillars of the social development, and it is an important factor in the economic development and social progress of human society. In recent years, for the energy demand is more and more huge, the energy supply has become a bottleneck problem. In the real background of social and environmental problems induced by increasing energy consumption, saving energy has become a consensus. This paper introduces three kinds of energy-saving technologies, which are Mechanical Vapor Recompression Heat Pump, Air-source Heat Pump, and Enhanced Vapor Injection technology respectively.Making full use of low grade energy can save energy to a certain extent. Therefore, two technologies of low grade energy utilization were introduced based on Organic Rankine cycle and Kalina cycle: one is that low grade energy is changed into mechanical work to generate power by using the positive cycle (Organic Rankine cycle or Kalina cycle), and the other is that low grade energy is changed into mechanical work to realize refrigeration by using the positive cycle.
