Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a heating, ventilation and air conditioning device for buildings. Background Art

[0002] Creating a healthy and comfortable indoor environment for buildings has increasingly become the focus of people's attention. Building ventilation is an important way to ensure the quality of the indoor air environment. However, in order to meet the requirements of energy conservation and emission reduction, modern buildings often improve their insulation performance by increasing the airtightness of their structures, which leads to a reduction in the number of air exchanges and a gradual deterioration of the indoor air quality.

[0003] When the current air conditioning device provides heating, it heats the air drawn from the room and then discharges it to increase the temperature inside the building. This makes the air inside the building not flow, and the air quality inside the building is greatly affected after the air conditioner works for a long time. Moreover, the temperature of the air inside the building is definitely higher than that of the outside air during heating. If the ventilation function is turned on, the heated air will be directly discharged outside the building, which is a great waste of resources. Content of the Utility Model

When the intake fan 26 rotates, a negative pressure is generated in the mixing bin 6. The air in the building is sucked through the air collection pipe 8, and the fresh air in the preheating bin 10 is sucked through the fresh air pipe 9. The indoor air and outdoor fresh air sucked by the air collection pipe 8 and the fresh air pipe 9 will be mixed in the mixing bin 6 to improve the air quality, and then flow into the heating box 5 to be heated by the heating wire, and then discharged into the building through the air outlet 3. By starting the servo motor 13, the worm 25 can be driven to rotate. The worm 25 will drive the worm wheel 24 to rotate. When the exhaust fan 22 connected to the worm wheel 24 operates, it will suck the indoor air to the tail of the air suction box 12, and then transmit the air to the temperature guiding pipe 16 through the connecting pipe 17 at the tail of the air suction box 12. When cold air from the outside enters the preheating bin 10, the temperature dissipated by the indoor hot air in the temperature guiding pipe 16 can preheat the fresh air, saving resources.
