In the meantime, Ingersoll and plass Kelvin line source in accordance with the concept of the underground pipe line heat source heat exchanger theory, but at that time because of low energy prices, high system costs, has not been widely applied. 70 era, the oil crisis put people's attention to the energy-saving, cost-effective use of energy, so that the development of ground-source heat pump into the climax stage, when the underground pipe from an early plastic pipes replaced by the amount of possession.

在此期间，Ingersoll和Plass根据Kelvin线源概念提出了地下埋管换热器的线热源理论，但当时由于能源价格低，系统造价高，没有得到广泛应用。70年代，石油危机把人们的注意力集中到节能、高效益使用能源，使地源热泵的发展进入了高潮阶段，此时地下埋管已由早期的金额管改为塑料管。
