The invention discloses a modulator integrating heating, refrigerating and ventilating. The modulator is mainly composed of an insulating material, a vacuum heat collecting pipe or a flat plate collector, refrigerating guide pipes, an adjustor shell, a heat storage tank, a cold storage tank, a heat storage heat exchanger, a cold storage heat exchanger, a compressor or a pump and a flow controller. A wing with the lower side being a hook surface is formed by the insulating material, the vacuum heat collecting pipe or the flat plate collector, the refrigerating guide pipes and the adjustor shell, and the wing integrates functions of heating and refrigerating. The heat collecting main piece vacuum heat collecting pipe or the flat plate collector is arranged at the upper portion of the wing. When the temperature of heat storage liquid in the heat storage tank is lower than the set value or the temperature of cold storage liquid in the cold storage tank is higher than the set value, a system is controlled to start heating or refrigerating collection and storage, some corresponding devices start to work, the compressor or the pump and the flow controller can be connected and run between the heat storage tank and the cold storage tank to increase the heat quantity of the heat storage tank and the refrigerating capacity of the cold storage tank, accordingly, wind energy is converted into the refrigerating capacity to be reused, and solar energy is converted into heat to be reused. The modulator is suitable for combined application of refrigerating, heating, ventilating and/ or a matched air conditioner system, a matched ventilation system and a matched cold and hot water supply system.
