An Indoor Ventilation and Cooling System Based on Bernoulli Effect

technical field

The utility model relates to an indoor ventilation and cooling system based on the Bernoulli effect, which belongs to the technical field of buildings.

Background technique

Every hot summer, the cool air-conditioned room has become a "summer resort" for many people. Although the air conditioner can indeed provide a comfortable living and working environment for the people in it, the working principle of the air conditioner is to make the room too much The heat of the air conditioner is transferred to the outside, so the air conditioner will make the already hot outdoor even hotter, and the power consumption of the air conditioner is large, and large-scale use does not conform to the concept of energy saving and emission reduction.

Contents of the invention

Aiming at the problems and deficiencies of the above-mentioned prior art, the utility model provides an indoor ventilation and cooling system based on the Bernoulli effect. The utility model utilizes the Bernoulli effect and the principle of evaporative heat absorption, and is provided with a prism-shaped air inlet on the outdoor wall. When the wind blows through the air inlet in a direction parallel to the wall, the local wind speed at the air inlet increases, causing The Bernoulli effect forms a low pressure at the air inlet, and the outdoor air is sucked into the air inlet. After the air enters the ventilation pipe, the temperature decreases after the evaporation and heat absorption of the moisture adsorbed on the cooler, and then the dehumidifier removes the excess air in the air. The water vapor is removed, the temperature of the air entering the room is naturally reduced, and finally it is discharged from the window of the building. The device is simple in design and low in cost. It uses the Bernoulli effect and the principle of evaporative heat absorption to cool the outdoor air and send it into the room under the condition of no power and zero energy consumption, which effectively reduces the indoor temperature.

Pull out the windshield 2 from the ventilation pipe 5, close the No. 3 cover plate 16, and open the outlet 8. When the wind blows through the air inlet 1 in a direction parallel to the wall, the local wind speed at the air inlet 1 increases, causing Bernoulli Due to the beneficial effect, a low pressure is formed at the air inlet 1, and the outdoor air is sucked into the air inlet 1. After being purified by the dust removal net 3 and the filter net 4, the air enters the ventilation pipe 5. , the air temperature decreases, and then the dehumidifier 13 removes the excess water vapor in the air, and finally the air enters the room through a number of holes 7 on the surface of the air blower 6, and is discharged from the outlet 8 after the overall temperature of the room is lowered. After cooling down, close the windshield 2 or the outlet 8 to interrupt the air circulation. Pay attention to adding water to the cooling device 9 and adding large particle dehumidifier to the dehumidifier 12 in time during use.

The beneficial effects of the utility model are:

This indoor ventilation and cooling system based on the Bernoulli effect is simple in design and low in cost.
