The invention relates to a defrosting system and method for an air source heat pump. According to the technical scheme, the defrosting system comprises an anti-freezing water tank, a defrosting tube 1, a defrosting tube 2 and a water pan, wherein an electrical heater is arranged in the anti-freezing water tank; the water pan is arranged at the lower part of an evaporator; the defrosting tube 1 and the defrosting tube 2 are mounted on the evaporator; an anti-freezing solution in the anti-freezing water tank is connected to the defrosting tube 1 in the evaporator through an anti-freezing water pump and a pipeline and connected to the water pan through the defrosting tube 2; an ice melting tube is arranged in the water pan, and an outlet of the ice melting tube is connected with the anti-freezing water tank, so that circulation of the anti-freezing solution is realized. The defrosting system and method have the benefits as follows: the water pan is separated from a supporting plate of the evaporator and fixed be
