Suspended turbulent flow fresh air system and using method

Abstract

The invention discloses asuspended turbulent flow fresh air system and a using method. The suspension turbulent flow fresh air system comprises a controllable fan and an indoor air supply guide pipe; a plurality of guide pipe air supply outlets are formed in the side face of the guide pipe, and the opening directions of the air supply outlets deviate from the horizontal direction and the vertical direction, so that the fan presses natural air into the indoor air supply guide pipe to form fresh air which is continuously blown to a wall from the air supply outlets in the side face of the guide pipe, the speed is changed between the walls, and the fresh air moves downwards to the room floor but not to the room floor in a zigzag manner; the indoor air is continuously diluted and diffused by the fresh air to become fresh air, the air pressure of the indoor air is continuously higher than the outdoor air pressure, and the indoor air is exhausted out of the room through the through holes of the room wall, so that people in the room can fully inhale the fresh air with high negative oxygen ion concentration to the lung, and toxic and harmful substances on the ground of the raising room can be prevented from being stimulated to flow upwards to the indoor human breathing space to be diffused when the fresh air touches the ground and rebounds. The system is suitable for common rooms which are poor in ventilation and lack of air negative oxygen ions, and is particularly suitable for common rooms with household air conditioners.

Description

Technical field: [0001] The invention relates to a fresh air system, in particular to a suspended turbulent flow fresh air system and a usage method. Background technique: [0002] People have used the fresh air system to ventilate the room for decades. The representative one is the two-way flow fresh air system. This fresh air system uses special equipment to send fresh air to the room on one side of the closed room. The fresh air comes from a height of about 2.2 meters. The air outlet blows vertically downwards to the ground and bounces up, spreads out and passes obliquely through the 0.1-meter-thick turbid air layer close to the ground, and enters the indoor living and breathing space with a height of 0.4-1.9 meters on the floor of the room, and the fresh air continues to spread Dilute the old air in the room to become new air, and finally the return air outlet on the other side of the room with a height of about 2.2 meters is sucked in and discharged outside, so as to ac...

AI Technical Summary

Problems solved by technology

This fresh air system has the following deficiencies: the fresh air comes out of the air outlet as a vertically downward high-speed airflow, and the process of passing through the indoor human breathing space is only about 1.5 meters, and the time is very short, so its high concentration negative Oxygen ions do not fully diffuse into the breathing space of indoor people, and are blown to the ground before they are absorbed and utilized by indoor people. When they rebound, they scatter in all directions and pass obliquely through the 0.1-meter-thick dirty air layer close to the ground, which stimulates the air to rise. Dust, dust mites, germs, mildew, moisture, formaldehyde, TVOC and other toxic and harmful substances on the floor of the room flow upward and rise to the indoor human breathing space to spread, so that people can neither inhale the fresh air with high concentration of negative oxygen ions nor have to Continue to inhale this new air containing toxic and harmful substances into the lungs
