DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 、 Figure 2As shown, a building HVAC energy-saving device includes: a fan 1 for supplying air; a thermostat 2 arranged behind the fan 1; a water curtain nozzle 3 arranged on the upper part of the thermostat 2; a water storage tank 4 connected to the water curtain nozzle 3, and the water storage tank 4 is also connected to the bottom of the thermostat 2; a refrigeration box 5 arranged behind the water storage tank 4; and a protective cover 6 arranged in front of the fan 1.

[0023] The device can be used by connecting it to the branch pipe of the HVAC pipe in the building.

[0024] The fan 1 blows air outward. During the rotation of the fan 1, the fan 1 transports the air in the thermostat 2 to the outside of the device. When the thermostat 2 is cold, the fan 1 blows out cold air. Similarly, when the temperature in the thermostat 2 is high, the fan 1 blows out hot air. This method can be used to adjust the temperature of a small part of the building.

[0025] The inner wall of the thermostat 2 is paved with an insulation board 21. After the temperature in the thermostat 2 is adjusted to a temperature different from the room temperature, the insulation board 21 prevents a large amount of heat from diffusing from the side walls of the thermostat 2, allowing the main air temperature to flow out from the fan 1, achieving energy saving and realizing the function of fixed-point temperature control.

[0026] An inspection shell 22 is provided on the rear wall of the temperature control box 2, and the inspection shell 22 is also made of insulation material. The inspection shell 22 surrounds the rear end outer wall of the temperature control box 2. When no inspection is being carried out, the inspection shell 22 is equivalent to the rear wall of the insulation box, which prevents the diffusion of hot and cold gases. When inspection is being carried out, the inspection shell 22 can be opened by sliding it upwards. A slider is provided on the inner wall of the inspection shell 22, and a slide is provided on the outer wall of the temperature control box 2. The slider is slidably connected to the slide. The slide limits the inspection shell 22 to only move vertically along the slide direction, thereby reducing the gap between the inspection shell 22 and the insulation box and reducing the loss of hot and cold gases.

[0027] There are multiple water curtain nozzles 3. When multiple water curtain nozzles 3 spray water at the same time, a water curtain is formed. The position of the water curtain nozzle 3 is higher than that of the fan 1. Water flows from top to bottom. The area of ​​the water curtain formed is larger than the area of ​​the fan 1. The direction of the water curtain nozzle 3 is located behind the fan 1. After the fan 1 is started, the cool air or hot air brought by the water curtain is brought to the outside by the suction force generated by the fan 1. The specific heat capacity of water is large and can be recycled for a long time to provide cool air and hot air, reducing the load of cooling or heating. At the same time, low-temperature water in the pipeline can be directly used for cooling, achieving energy-saving effects. When the water curtain falls downward, the dust entering from the fan 1 is wetted by the water curtain so that it cannot float away. A water permeable hole 42 is provided at the bottom of the thermostat 2. After the water curtain falls to the ground, it enters the water storage tank 4 through the water permeable hole 42.

[0028] The water curtain nozzle 3 is connected to a water pipe 7, the bottom of which is located at the bottom of the water storage tank 4. A water pump 71 is installed on the water pipe 7. When the water pump 71 is started, water in the water storage tank 4 is brought into the water curtain nozzle 3 through the water pipe 7, thus forming a water circulation. When the water temperature reaches the room temperature, the water source is replaced and a new round of temperature adjustment is performed.

[0029] A heating wire 41 is arranged at the bottom of the water tank 4 and is connected in a serpentine shape. When heat is needed in winter, the heating wire 41 can be turned on to heat the water in the water tank 4, causing the water curtain to emit hot air. At the same time, the hot air in the water tank 4 also moves upward through the water permeable holes 42 and is eventually carried out to the outside by the fan 1. When the heating wire 41 stops, the heat in the water can continue to dissipate. Compared with directly using the heating wire 41 to dissipate heat, hot water heat dissipation can maintain a longer temperature output.

[0030] A water inlet pipe 44 is provided on the side wall of water tank 4, and a water outlet pipe 45 is provided at the bottom of water tank 4. Valves are installed on water inlet and outlet pipes 44 and 45. These pipes are connected to the main pipeline. When cooling air is needed and the water temperature is low, the valves are opened to continuously refresh the water in water tank 4, using the water flowing through the pipes to provide cooling air. When the water temperature in the main pipeline is high or needs to be increased, the water in water tank 4 is replenished and the valves are closed. The water in water tank 4 is then cooled or heated, allowing the water retained in water tank 4 to absorb cooling energy or heat energy.

[0031] A partition plate 43 is provided between the water storage tank 4 and the refrigeration box 5. The partition plate 43 is provided below the inspection shell 22. Water flowing out of the water permeable hole 42 will not flow into the outside of the partition plate 43. An air vent is provided on the top of the partition plate 43, and the air vent can be connected to the refrigeration box 5. The bottom of the partition plate 43 is a solid plate. When the water storage tank 4 is storing water, it is necessary to control the water level line not to exceed the height of the solid plate.

[0032] A heat insulation board 51 is detachably connected between the refrigeration box 5 and the partition 43. The heat insulation board 51 is slidably connected to the top of the refrigeration box 5. When the water storage tank 4 needs to be cooled, the heat insulation board 51 is pulled out. A drawer 52 is provided in the refrigeration box 5. Ice cubes are placed in the drawer 52. The cold air from the ice cubes enters the water storage tank 4 through the vents to cool the water. Some of the cold air can also enter the temperature control box 2 through the water permeable holes 42. When the water storage tank 4 is heated, the heat insulation board 51 is installed to prevent hot air from escaping through the vents.

[0033] The protective cover 6 is generally in the shape of a quadrangular pyramid, and a flexible hose 61 is provided at the front end of the protective cover 6. The opening of the protective cover 6 gradually contracts. When the fan 1 is in operation, some water vapor is drawn into the protective cover 6, which blocks the water vapor and prevents it from being sprayed out when the fan 1 rotates. When in use, the flexible hose 61 can be turned to blow hot or cold air to the location where the temperature needs to be adjusted.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
