The invention relates to an air source heat pump device free from defrosting and capable of outputting cold or hot water. The device comprises a compressor, a condenser/evaporator, an expansion valve, an evaporator/condenser, a solution heat exchange unit which exchanges heat with a refrigerant flowing through the condenser/evaporator, a circulating pipeline connected with the evaporator/condenser and used for outputting cold or hot water, and a water pump. According to the device disclosed by the invention, through the heat exchange between a heat exchange solution and the refrigerant flowing through the condenser/evaporator, the condenser/evaporator is not in direct contact with the air. Because the freezing point of the heat exchange solution is low, even in cold winter, the condenser/evaporator cannot frost. According to the device disclosed by the invention, a heat exchange core body is stuffed with honeycomb anti-corrosion stuffing, so that the contact surface area of the heat exchange solution and the heat exchange core body is increased; in addition, the viscosity of the heat exchange solution is large, so that attachment of the heat exchange solution to the stuffing is facilitated, and the contact time of the solution and the air is prolonged; therefore, the heat exchange efficiency is improved, and realization of the miniaturization of air conditioning equipment is facilitated.
