蒸发冷却式冷凝器在高温环境下的应用

摘要

针对肋片管式冷凝器在夏季高温和强辐射等恶劣气候条件下运行时,经常出现换热效果下降的问题,提出了采用蒸发冷却式冷凝器来改善换热效果的措施.针对蒸发冷却式冷凝器在高温环境下的性能与在分体式空调器中的应用进行了实验研究.结果表明,在39℃高温环境下,蒸发冷却式冷凝器可有效提高换热效果及分体式空调器的能效比.%Considering the usual reduction of heat transfer capacity of fin-and-tube condenser operated on extreme condition of hot summer and strong radiation, puts forward a measure for improving heat transfer by adopting evaporative cooling condenser. Tests the capacity of evaporative cooling condenser applied to high temperature environment and its application to split air conditioners. The result shows that the evaporative cooling condenser can enhance the heat transfer capacity effectively and the energy efficiency ratio of split air conditioner in high temperature environment of 39 ℃.
