The utility model discloses an air source heat pump system facilitating chassis deicing and improving heating capacity, and relates to the technical field of air source heat pumps. The system comprises a compressor, an efficient tank, an economizer, an evaporator, an evaporator supercooling pipe, a main path electronic expansion valve, a one-way valve, a gas-liquid separator, an auxiliary path electronic expansion valve and a four-way valve. According to the utility model, a rear liquid taking mode is adopted as an economizer liquid taking mode, so that the supercooling degree of a liquid refrigerant in front of the valve can be better improved, and the heating capacity is improved; the liquid refrigerant after the main path of the economizer is supercooled is guided into the evaporator supercooling pipe, so that on one hand, the supercooling degree of the liquid refrigerant can be further improved, and the supercooling degree of the liquid refrigerant of the main path can be further improved when the unit ru
