Influence of demand heating-cooling ratio on annual performance factor of air-cooled multi-connected air conditioning(heat pump)systems
This paper presents the calculation model for annual performance factor of air-cooled multi-connected air conditioning(heat pump)systems and the influence mechanism of the demand heating-cooling ratio on the annual performance factor,analyses the influence factors of demand heating-cooling ratio in the practical engineering,provides the calculation method for demand heating-cooling ratio and the calculation idea for annual performance factor in the practical engineering,and provides the calculation results of demand heating-cooling ratio for a typical office building under different energy saving standards for reference.
