Embodiment 1

[0093] As shown in Figures 1 and 2, the wind tower airflow power generation device includes a wind tower 1, a prime mover 2, an asynchronous generator 3, a total air extractor 4, a water pump 5, a spray device 6, an underground water collection well 7, and a battery 8. The automatic control device for power switching. The prime mover 2 is a vertical-axis propeller wind turbine or turbine, which is installed in the center of the lower part of the wind tower 1; The circulation air channel 9 at the bottom and the upper part, the total air extractor 4 is located at the air outlet of the circulation air channel 9; the spray device 6 is installed in the upper part of the wind tower 1, and the water pump 5 is connected with the underground water collection well 7 and the spray device 6 respectively. The underground water collection well 7 communicates with the tail pond 10 provided at the lower end of the wind tower 1; the prime mover 2 is connected with the asynchronous generator 3 o...

Embodiment 2

[0101]As shown in Figures 4 to 9, when the wind tower 1 supplies air to more than two small multi-storey buildings 12 at the same time, a combination of wind tower plus tunnel and centralized dehumidification / drying can be used: the wind tower 1 is located in each building 12 Between, the basement 17 of building 12 is communicated with the air outlet of wind tower 1 bottom circulating air passage 9 through gas transmission tunnel 18, and tunnel air extractor 19 is arranged in gas transmission tunnel 18, and the top of basement 17 communicates with each The floor air ducts are connected, the main air supply outlet is equipped with a main air supply fan 20, a centralized dehumidification / drying device 21 is installed in the basement 17, and the basement 17 is also equipped with a solar heat storage wall-exhaust chimney The main inlet 22 and the main outlet of hot gas 23 and the auxiliary air extractor 24 located at the total entrance, the motor starter of the tunnel air extractor...

Embodiment 3

[0104] As shown in Figures 10-11, when the building 12 is a middle and high-rise residential building with an elevator shaft 27, a combination of nuclear tube wind tower and direct dehumidification / drying can be used: the wind tower 1 is located in the middle of the building 12, The wind tower 1 is symmetrically provided with four circulating air passages 9, which are respectively connected with the air passages of each layer, and each layer of the solar heat storage wall-exhaust chimney is equipped with a direct dehumidification / drying device 25 with automatic control of intermittent switching valves , so that the air-conditioning chamber 13 is in the air intake and exhaust states at regular intervals, that is, the cold air is dry during intake, and the desiccant is regenerated during exhaust.

[0105] Other parts of this embodiment are similar to Embodiment 1.

[0106] In the case of Embodiments 1 to 3, since the circulating air channel 9 is also the main channel for supplyi...

Abstract

The present invention provides a wind tower air-flow power generation method and its application in the underground cold / heat source direct air-conditioning system. Said wind tower air flow power generation method is characterized by that it uses the mechanical energy formed under the common action of artificial air flow, atmospheric thermal pressure difference and natural wind force as motive power and makes the wind turbine positioned in the wind tower bottom portion be reached to rotating speed for power generation to drive asynchronous generator to make power generation. Said invention also provides the concrete structure of said wind tower and its conrete working principle and operation method.

Description

technical field [0001] The invention relates to an active energy-saving air-conditioning system for ordinary buildings, in particular to wind tower airflow power generation and its application in direct air-conditioning of underground cold / heat sources. Background technique [0002] There are many kinds of solar energy utilization technologies that have been proposed, and the generalized solar energy utilization includes technologies in both buildings and facilities. Passive solar energy utilization refers to purely architectural and structural measures, and active solar energy technology generally refers to equipment and must be assisted by conventional electric (energy) sources. Conventional power here refers to regional power (grid). Solar energy cold room (cooling in summer) is technically complex and expensive, and it is still relatively rare at home and abroad so far. It is only practical to evaluate the existing technical level together with the current cost (cost)....
