一、热泵的原理热泵的原理是在1824年由卡诺提出,而在日本则是到二十世纪初才出现。但是,在当时煤处于顶盛时期,回收使用电气的能量比较昂贵,在经济上是不合算的。直到最近,伴随节能、防止大气污染和供冷供暖装置的普及,热泵的用途才日趋广泛。 First, the principle of heat pump The principle of heat pump was proposed by Kano in 1824, but in Japan it did not appear until the early 20th century. However, at the time when coal was at its peak, the use of electrical energy for recycling was expensive and economically uneconomical. Until recently, with the advent of energy conservation, air pollution prevention, and the popularity of cooling and heating systems, the use of heat pumps became more widespread.
