摘要

丹麦1%的农场从动物饲养场回收热量。一开始，也就是说在70年代，主要使用铜铝的空气/水蒸发器。由于腐蚀问题，目前大多数热泵都是带PVC和PEL等人造材料外部换热器的水/水类型。动物饲养场的17台热泵的现场测试已经完成，另外20台热泵的实验已经开始。结果表明，考虑到压缩机、通风机、循环泵等的总能耗，平均影响因子为2.3。仅压缩机的平均影响因子是3.0。在不久的将来，2.5–3.0的影响因子似乎是可能的。

Recovery of heat from animal houses by using heat pumps

Recovery of heat from animal houses takes place in 1% of all Danish farms. At the beginning, which means in the Seventies, air/water evaporators of copper-aluminium were mostly used. Because of problems with corrosion, most of the heat pumps today are water/water types with external heat exchangers of artificial material such as PVC and PEL.

Field testing is complete with 17 heat pumps for animal houses, and experiments with an additional 20 units have been initiated. The results show that the mean effect factor is 2.3, taking into account the total energy consumption for compressor, ventilator, circulation pumps etc. The mean effect factor concerning the compressor alone is 3.0.

In the near future an effect factor of 2.5–3.0 seems to be possible.
