The invention discloses a hot air and hot water combined supply device based on an air source heat pump and belongs to the field of circular heat exchange. The hot air and hot water combined supply device comprises a water storing box and a heat pump system exchanging heat with water in the water storing box. A loop of the heat pump system comprises an evaporator, a compressor, a condenser and a throttling valve which communicate through a pipeline sequentially. Refrigerant is introduced into the pipeline. The condenser is arranged in the water storing box. The hot air and hot water combined supply device further comprises an air way system exchanging heat with the water in the water storing box. The air way system comprises an air channel, a fan arranged on the upstream of the air channel, and a first micro channel heat exchanger arranged on the middle portion of the air channel. An air outlet is formed in the downstream of the air channel. An inlet and an outlet of the first micro channel heat exchanger communicate with the water storing box. The inlet is provided with a pressure pump for pressing hot water into the first micro channel heat exchanger. The outlet is provided with a water pump used for pumping the water in the first micro channel heat exchanger out. The device can supply hot water and hot air at the same time, the water and air heat exchange efficiency is improved substantially, and cost is reduced greatly while energy consumption is low.
