The utility model discloses a residential building fresh air waste heat utilization system based on an air source heat pump. Waste heat of a residential building fresh air system is effectively recycled based on the air source heat pump. The fresh air handling unit is connected with all residence houses through an air supply pipeline and an exhaust pipeline. The split type evaporator is connected with the fresh air handling unit through a fresh air switch valve and an exhaust switch valve and communicates with the outside through an outdoor communicating pipeline. A fresh air inlet and an exhaust air outlet of the fresh air handling unit are connected with a fresh air bypass valve and an exhaust air bypass valve respectively. A refrigerant inlet and a refrigerant outlet of the split type evaporator are connected with an outlet of the electronic expansion valve and an inlet of the scroll compressor. An outlet of the scroll compressor is connected with an inlet of the electronic expansion valve through the heat
