The invention relates to a solar house system, in particular to a solar house system suitable for the severe cold area. The solar house system aims at solving the problems that as for an existing town solar house in the severe cold area, the heating temperature of an indoor heated brick bed is low in winter, fresh air does not exist indoors, the air quality is poor, and due to solar radiation, the solar house is overheated in summer, and the indoor heat comfort is influenced. The solar house system comprises a passive solar house, a hung brick bed, a fresh air fan, a smoke discharging channel, a buried pipe, stop valves, refrigerant circulating pipes and a heat preservation water tank. Three direct benefiting windows are installed in the passive solar house, two first solar heat collecting walls and two second solar heat collecting walls are arranged on the passive solar house, the hung brick bed is installed in the passive solar house, one end of the buried pipe extends out of the ground, the other end of the buried pipe is inserted into the smoke discharging channel and extends into the solar house, the fresh air fan is installed at the position, located at the ground, of the buried pipe, the refrigerant circulating pipes are arranged in an air heat channel and the heat preservation water tank, and the stop valves are installed on the refrigerant circulating pipes. The solar house system is used for the town solar house in the severe cold area.
