世界上第一台太阳能水泵据说是在1615年由法国工程师所罗门·德·考克斯发明的。经过了一段较长的时间后,太阳能水泵的研制工作又有了发展。1976年,D.P.Rao和K.S.Rao曾提出一种用于抽升灌溉用水的太阳能水泵,这种泵的原理不同以往,它不是用太阳能发动机、太阳电池发电机来带动,而是一种汽压式或气体活塞式太阳能水泵。它用太阳能平板集热器,和低沸点、轻质烃类化合物(例如,正戌烷、丁烷或氟利昂)为工作介质(或
The world’s first solar water pump was said to have been invented by French engineer Solomon de Cox in 1615. After a long period of time, the development of solar water pumps has developed. In 1976, DPRao and KSRao proposed a solar water pump for pumping irrigation water. The principle of this type of pump is different from the past. It is not driven by a solar engine or a solar generator, but it is a type of steam pressure type. Or gas piston type solar water pump. It uses solar plate collectors, and low-boiling, light hydrocarbon compounds (for example, n-decane, butane, or freon) as working media (or
