太阳能是巨大的、无污染的自然能源。利用太阳能致冷或制冰,具有特殊的优越性。因为无论是从一年的季节变化或一天的气温变化来看,只要太阳辐射强度越大,天气越热,所能提供的致冷量就越多,并且效率也越高。这就是说,能量的供和求两方面是完全协调一致的。从历史上说,利用太阳能制冰,至今已经一百多年了。早在一八七八年,法国人艾贝尔·皮弗雷就曾在巴黎利用一台聚光型太阳能集热器,使锅炉产生蒸气来发动原始的吸收式致冷 Solar energy is a huge, unpolluted natural source of energy. The use of solar cooling or ice, with special advantages. Whether it is a seasonal change in a year or a one-day temperature change, the greater the solar radiation intensity and the hotter the weather, the more cooling capacity is available and the more efficient it is. This means that both the supply and demand of energy are fully coordinated. Historically, the use of solar ice has been more than a hundred years. As early as 1878, the Frenchman Abel Pigeon used a concentrating solar collector in Paris to generate steam to initiate the original absorption refrigeration
