[0003] The invention patent, currently published with the publication number CN103868275A, discloses an air-source heat pump system. When the solar collector's heat medium temperature reaches 27°C-35°C, meeting the air-source heat pump operating conditions, the intelligent control module controls the first and second control valves to open, while simultaneously closing the third and fourth control valves. When the solar collector's heat medium temperature exceeds 35°C, exceeding the air-source heat pump operating conditions, the intelligent control module controls the first and second control valves to close, while simultaneously opening the third and fourth control valves. This invention adds a second solar thermal auxiliary flow channel to the existing evaporator, raising the evaporator temperature and eliminating the common problem of frost.
