An indirect multi-level waste heat recovery heat pump air-conditioning system, and a control method therefor. The control method comprises: by means of a compressor, controlling the flow of a refrigerant; by means of a first water pump (201), a second water pump (301) and a third water pump (402), controlling the flow of a cooling liquid; by means of a blower (501) and a fan (502), controlling the flow of air; controlling the heating power of a first heater (202) and a second heater (403); and, by means of a first one-way valve (102), a first electronic expansion valve (104), a second one-way valve (106), a second electronic expansion valve (107), a third electronic expansion valve (109), a three-way valve (304), a third one-way valve (401), and a fourth one-way valve (405), controlling communication and disconnection of fluids, or achieving specified flow states, thus satisfying various thermal management requirements under all-weather conditions, and reducing energy consumption by means of reasonable utilization of waste heat.
