摘要
为提高空气源热泵的性能,同时更好地满足煤矿井口防冻特殊工艺要求,将空气源热泵与热管技术相耦合,使用小压比热泵机组搭建了空气源分体式热管-热泵供暖系统实验平台.该耦合系统中蒸发器和冷凝器两端均采用相变传热的方式,并对其进行不同运行工况下的性能特性研究,结果表明:该耦合供暖系统即使在 0℃左右的室外条件下,耦合机组的系统制热性能仍可达到4.5 以上,远远优于传统空气源热泵机组.
Abstract
In order to improve the performance of air source heat pump and better meet the special technical requirements of wellhead antifreeze,an air source split heat pipe heat pump heating system ex-perimental platform was built by coupling air source heat pumps with heat pipe technology and using a small pressure ratio heat pump unit.In this coupled system,phase change heat transfer is adopted at both ends of the evaporator and condenser,and their performance characteristics under different opera-ting conditions are studied.The results show that even under outdoor conditions around 0℃,the Coe-fficient of Performance(COP)can still reach 4.5 or above,far superior to traditional air source heat pump units.
