The invention discloses a temperature-controllable air heat recovery device and a control method thereof, and belongs to the field of building energy saving and ventilation and air exchange. The air heat recovery device adopts a heat pipe and thermopile integrated technology, the heat recovery efficiency of fresh air of a single heat pipe is reinforced, through the invented heat pipe and thermopile combined mode, tightness is improved, heat transfer is reinforced, and meanwhile, the temperature control function can be achieved through the corresponding control method. The temperature-controllable air heat recovery device comprises a fresh air side heat pipe set (1), an exhaust side heat pipe set (2), a thermopile (3), a heat pipe and thermopile connecting sleeve head (4) and a current controller (13). In winter, heat of exhausted air is recovered to heat the fresh air, and in summer, the cooling capacity of the exhausted air is recovered to cool the fresh air. The current controller (13) can regulate the refrigerating capacity or the heating capacity of a heat exchange core, and thus the set temperature is maintained. The air heat recovery device adopts the heat pipe and thermopileintegrated technology, the size is small, the temperature can be controlled, the air heat recovery device can be applied to a domestic window-type fresh air ventilator, the indoor attractiveness is not affected after mounting, and the good development prospects are achieved.
