摘要(Abstract):

基于提高空气源热泵在低温环境下的制热能力,针对低温环境下空气源热泵空调机组制热能力降低的原因,分析了可能采取的措施,提出了一种新的空气源热泵流程,并对采用该空气源热泵的低温制热性能进行了试验研究。
A modified refrigeration cycle for air source heat pump system to heighten its heat capacity while it running at low ambient temperature was presented.The flow chart of the new refrigeration cycle for the ASHP was introduced in detail.Several proposes improving measure for the heat pump system to increasing heating capacity of the heat pump while it working at low ambient temperature had been also analyzed.The heating performance of the new ASHP had been tested.
