Daily and epidemic dual-purpose attached ventilation airflow environment regulation and control device

Abstract

The invention discloses a daily and epidemic dual-purpose attached ventilation airflow environment regulation and control device which comprises a static pressure chamber, and a mushroom head device and a table top are arranged at the upper portion of the static pressure chamber. The mushroom head device comprises a large air pipe, an arc-shaped plate and an air outlet plate. An air outlet is formed in the air outlet plate, an air inlet is formed in a bottom plate of the static pressure chamber, the air inlet is connected with an underground air supply system, and a draught fan is installed onthe air inlet. A central air supply opening and side air supply openings are formed in a top plate of the static pressure chamber. Small air pipes are connected to the central air supply opening, anda flow guide plate is arranged above each side air supply opening. A large air pipe is arranged outside the small air pipes in a sleeving manner and connected with a lifting mechanism, and the lifting mechanism is used for driving the large air pipe to ascend and descend. When the mushroom head device descends, air is supplied through the side air supply openings in the two sides, an air curtainwith a certain speed is formed above the arc-shaped plate, and cross infection between people is avoided. When the mushroom head device ascends, air flow is sent out from the central air supply opening, a layer of air lake is formed on the table top, and the micro-environment around people is improved.

Description

technical field [0001] The invention belongs to the technical field of heating, ventilating and air conditioning, and relates to a dual-purpose anti-epidemic and attached ventilation airflow environment control device. Background technique [0002] With the advancement of science and technology, more and more work is transferred from outdoors to indoors, and the indoor environment is directly related to the health and working status of personnel. Commonly used ventilation methods include mixed ventilation and displacement ventilation. Mixed ventilation forms a uniform thermal environment indoors by sending in treated outdoor air and part of the return air, and dilutes indoor pollutants. The air quality is poor and energy consumption Big. Displacement ventilation forms an air lake on the upper part of the floor through the lower air supply port. The ventilation efficiency is higher, the indoor air quality is better, and the energy consumption is small, but the indoor load it...

Problems solved by technology

In order to ensure sufficient residual pressure at the air supply outlet of the partition, the traditional air supply for the workstation is often used together with a small fan at the bottom of the partition air duct. This kind of air supply for the workstation can only meet the requirements of the microenvironment around the human body. demand, but it cannot effectively avoid cross-infection among personnel during the epidemic period
