nfluence 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.
