Solar air conditioner heating and ventilation equipment

The utility model provides solar air-conditioning heating and ventilation equipment, which is suitable for production and application of heating and ventilation and comprises a protection box and an air bellow, the protection box is divided into an inner layer and an outer layer, a preheating cavity is arranged between the outer layer and the inner layer of the protection box, and the air bellow is fixed at the front end of the protection box. The protection box has the beneficial effects that the electric heating wire is additionally arranged in the double-layer structure of the protection box to preheat the inner wall of the protection box, so that when the heating pipe in the protection box is used, the temperature difference between the inner wall and the outer wall of the inner layer of the protection box is reduced, and vaporized water molecules are prevented from being in contact with the inner layer of the protection box to be liquefied into water drops; therefore, the heater and the heating pipe in t
