The invention relates to a split type efficient defrosting air source heat pump unit which comprises a heating heat pump cycle and further comprises a plurality of air cooling modules and a defrosting heat pump cycle. The unit is divided into an indoor unit, a heat pump defrosting module and a plurality of outdoor units, and a heating heat pump cycle and related pipelines serve as the indoor unit; the defrosting heat pump cycle is used as a heat pump defrosting module; and each air cooling module is used as an outdoor unit. Equipment included in the unit is arranged in one indoor unit, one heat pump defrosting module and a plurality of outdoor units respectively, so that processing and field installation of the whole unit are facilitated: during field installation, one indoor unit, one heat pump defrosting module and the plurality of outdoor units are directly connected through secondary refrigerant pipelines; and the heat pump hot water unit capable of ensuring that the heating capacity attenuation is very s
