摘要
低温制热能力不足问题一直是空调的诟病,研发人员在前期也提出过几种解决温制热量的方案,但都以难满足APF工况下的能效提升和低温-15℃环境温度下高制热量的两个目标。针对这一难题,提出一种集变频技术、变容技术和喷气增焓技术为一体的压缩机设计方案,通过原理分析进行了样机的结构设计,研究其性能及低温能力特性,经验证,搭载空调系统测试时,喷气能力能效提升效果明显,在喷气情况下,搭载系统APF比基准机型提高了约6%,同时,搭载系统的低温-15℃的制热能力相对基准机提升了约85%,效果显著。
The lower heating capacity in low ambient temperature is the defect of the air-conditioner. Some schemeshave been proposed to solve the problem, but they can＇t improve the quantity of heat more than 50% in low ambient temperatureand improve efficiency in general temperature at the same time. This paper proposes a vapor-injection varicapcompressor, and studies its heating capacity and efficiency properties. The experimental results show that the APF of theair-conditioner increased by 6% when using the vapor-injection varicap compressor, and the quantity of heat increasedby 85%, at the same time.
