As shown in fig. 1 to 13, the solar and wind energy integrated air conditioning device provided by the present embodiment has the following working principle:
the illustration shows a portion of the center of the greenhouse 100, and the devices may actually be extended to both sides according to the length of the greenhouse 100. When the sun, the electric quantity can be collected to solar cell panel 11, and the temperature that solar cell panel 11 is heated simultaneously can be transmitted for holding water box 21 of below. The hot water tank 21 transfers hot water to the inside of the frame 41 and the inside of the geothermic plug 51 through the heat exchange water pipe to heat the soil and the space in the greenhouse 100. The greenhouse 100 adopts a double-layer structure, and can keep the temperature of the greenhouse 100. The temperature of the heat-insulating water tank 21 is small, so that the temperature is rapidly increased, and the temperature of the geothermal plug 51 in the greenhouse 100 and the temperature of the water pipe in the frame 41 are high. When the temperature of the water is continuously raised by the solar energy, the pressure release valve 221 beside the heat preservation water tank 21 is pushed open due to the expansion of the water caused by heating, and the heat preservation water tank 21 on the upper layer is communicated with the heat preservation water tank 21 on the lower layer. The heat is transferred to the lower heat-preservation water tank 21 to store more heat. While ensuring that the temperature within the greenhouse 100 does not continue to rise. After the temperature of the lower heat-preservation water tank 21 reaches a certain temperature, the lower heat-preservation water tank 21 is communicated by analogy, so that more heat-preservation water tanks 21 store heat. When the sun is not present, the greenhouse 100 can be heated by means of the stored heat. In summer, the plurality of hot water tanks 21 are first filled with liquid through the coolant filling port above the hot water tanks 21 and the pressure relief valves 221 are all pressurized open. The coolant filling port extends out of the soil, so that liquid can be conveniently added. Then, the temperature adjusting bin connecting pipe 35 connected above the temperature adjusting bin 33 on the side surface of the heat preservation water tank 21 can be used for filling liquid into the temperature adjusting bin 33, so that the original air medium is replaced, the heat preservation water tank 21 is connected with the outside through water, heat dissipation is achieved, and high temperature in summer inside the greenhouse 100 can be relieved through heat dissipation. In order to facilitate the addition of liquid, the temperature-regulating bin connecting pipe 35 extends out of the soil.
