摘要
设计一台三匹压缩机热泵实验台,将太阳能热水系统和空气源热泵结合,介绍该热泵系统的工作原理、结构。系统能够满足不同季节制冷、采暖和供热的需求,根据系统的不同工作模式,热水箱在系统的接入位置可以通过阀门进行灵活切换。为了适应不同工况的能量调节需求,采取对室外机风机和压缩机进行变频控制,并研究在无太阳能作为辅助热源的情况下风机转速和压缩机功率变化对产热能力的影响。
Designs an experimental equipment which combines a solar heated water system and an air source heat pump with a 3 HP variable frequency compressor heat pump together. Introduces the principle and the structure of the system according to the different working modes in different season. This system can meet all kinds of demand on refrigeration, heating and hot water supply in different seasons. The place where hot water tank joins with the system can be changed flexibly by valves in terms of different working modes to meet the demands of refrigeration, heating or hot water supply in the whole year. In order to adjust to different power input in different working modes, the frequency conversion control is used on the outdoor fans and compressor. The effect of the fans＇ and the compressor＇s rotary velocity variation on heat capacity is studied in the further experiment.
