System device for solving problems of supercooling of supplied air of air conditioner in hot and humid areas and cooling of photovoltaic curtain wall

The invention discloses a system device for solving supercooling of supplied air of an air conditioner in a hot and humid area and cooling of a photovoltaic curtain wall, which comprises an air conditioning system device arranged in a building envelope structure and a photovoltaic curtain wall structure device arranged outside the building envelope structure, the air handling unit treats mixed air of fresh air and return air to a machine dew point so as to guarantee sufficient dehumidification, dew-point air is conveyed into an interlayer space of a photovoltaic curtain wall through an air supply pipeline, waste heat of a photovoltaic module is recycled to be used for preheating the dew-point air, and the dew-point air and the preheated air are sufficiently mixed and then conveyed into a room. Dew-point air reheating and photovoltaic curtain wall ventilation cooling are combined, so that the problem of air supply supercooling caused by dehumidification of an air conditioning system in a hot and humid area is
