如何提高高溫熱泵的工作效率

如何提高高溫熱泵的工作效率

   影響高溫熱泵的效率有二個因素,一是熱泵循環的內部損失大小通俗的說就是壓縮機機械損二是高溫端和低溫端換熱器的不可逆轉熱損失。

  Affect the efficiency of high temperature heat pump has two factors, one is the heat pump circulation internal loss size popularly said compressor mechanical loss is two high temperature end and low temperature end heat exchanger irreversible heat loss.

  主要還是跟載熱介質有關,以水為載熱介質的熱泵其熱泵效率一般要大于相同溫度范圍工作的空氣熱泵, 大型熱泵系統由于壓縮機效率較高和流程損失相對較少其熱泵效率一般要大于小型熱泵,隨著高低位熱源的溫差加大,熱泵系數總是降低的。而對較大型的系統可采用多級壓縮、回熱等各種措施減少不可逆損失,從而提高熱泵效率。隨著大型全封閉和半封閉式壓縮機技術的成熟及高溫熱泵工質研究的進展,開發和生產供熱溫度為100 ℃~150 ℃的地源、水源或空氣源高溫熱泵裝置并不困難,其關鍵是如何降低熱泵裝置成本和提高它的效率。

It is with the heat carrying medium, air heat pump with water as the heat pump heat carrying medium of the heat pump efficiency higher than the same working temperature range, large heat pump system due to high efficiency of the compressor and flow loss is relatively less than the pump efficiency of small heat pump with high temperature, low heat source heat pump coefficient increase, always reduced. For large systems, multi-stage compression, heat recovery and other measures can be used to reduce irreversible losses, thus improving the efficiency of heat pump. With the development of large-scale closed and semi closed compressor technology and high temperature heat pump research, development and production of heating temperature is 100 DEG C to ground source, water or air source heat pump device high temperature 150 DEG C is not difficult, the key is how to reduce the cost and improve the efficiency of heat pump it.
