能源的蕴藏有限,而能源的需求日增。努力开发新能源,乃是人类发展历史的必然趋向。太阳能的种种优越性,诱使人们对太阳能的利用倾注了无数的心血。时至今日,利用太阳能来生产热水,进行房屋采暖,已经积累了相当丰富的经验,可以说正处于提高,推广的阶段。至于太阳能发电,无论是光—热—电转换还是光—电转换,都还在继续探讨,以求提高效率、降低成本,俾能达到实用水平。太阳能是以热辐射的形式发挥作用的,而制冷则是要从低温处取出热量。要以热来制冷岂非南辕北辙吗?回答是:行。按照热力学第二定律,如果补偿一定量的能量,可以将热量 The energy reserves are limited, and the demand for energy is increasing. Efforts to develop new energy sources are the inevitable trend in the history of human development. The advantages of solar energy, to induce people to use solar energy poured countless effort. Today, the use of solar energy to produce hot water for house heating has accumulated a wealth of experience, we can say is in the stage of promotion, promotion. As for solar power generation, both light-heat-electricity conversion and light-electricity conversion are still going on in order to increase efficiency and reduce costs so as to achieve practical levels. Solar energy is in the form of thermal radiation, while cooling is to remove heat from low temperatures. To heat it to the opposite direction? Answer is: OK. According to the second law of thermodynamics, if you compensate a certain amount of energy, you can heat
