Embodiment 1
[0039] Embodiment 1: When there is a season of floral fragrance outdoors, such as spring, autumn or summer, the air intake device in the air intake unit 1 can be opened accordingly, and its working process is: the outdoor air with floral fragrance is filtered by the air intake cap 3 Enter the branch air duct 4, adjust the speed of the ventilator 5 and the opening of the air valve 6 to control the amount of air entering the main air duct 7, and the air in the main air duct 7 is cooled with the geothermal energy exchange area 13 with a relatively stable temperature in the soil 14 , the cooled air enters the working area of the indoor 9 through the air outlet 8 at a relatively low wind speed, and the fresh air sent in provides the natural fragrance of flowers and plants for the indoor 9, and at the same time takes away the waste heat and dirty air in the working area. The tuyere 10 is discharged outdoors.
Embodiment 2
[0040] Embodiment 2: When the outdoor air temperature is high, such as hot summer, for mountainous areas, the air temperature difference between the area under the shade of trees and the area exposed to sunlight is relatively large, and the outdoor air can be introduced by the air intake unit 2 under the shade of trees , its working process is as follows: the air with an outdoor temperature of 30°C enters from the air intake unit 2 under the shade of a tree, is filtered by the air intake cap 3 and enters the branch air duct 4, and adjusts the speed of the ventilator 5 and the opening of the air valve 6 to control the entry The air volume of the main air duct 7 with a buried depth of 4m, and the length of the main air duct 7 are obtained according to the design requirements of the indoor temperature and in combination with the basic principle of buried pipe heat exchange.
[0041] For example, the diameter of the main air duct 7 is 200mm, and when the indoor design temperature i...
Embodiment 3
[0043] Embodiment 3: when the outdoor air temperature is low, such as cold winter, the outdoor air can be entered by the air intake unit with strong solar radiation heat in winter, and enter the branch air pipe 4 after being filtered by the air intake cap 3, and adjust the speed of the ventilator 5 The opening of the air valve 6 controls the amount of air that enters the main air duct 7 with a buried depth of 4m. It can be obtained through heat exchange calculation that the outdoor air exchanges with the geothermal energy in the soil 14 with a relatively constant temperature through the main air duct 7 with a length of 15m. The temperature rise of the air in area 13 (soil temperature is about 18°C) is about 10°C after indirect heat exchange, and the air after heat exchange enters the working area of indoor 9 through air outlet 8 at a relatively low wind speed, providing warmth for indoor 9 air.
[0044] Through the above-mentioned embodiments, the present invention effective...
