Central air-conditioning system applying ultrafine particle purifying device, and method for purifying air using same

Abstract

The invention provides a central air-conditioning system applying an ultrafine particle purifying device. The system is characterized by comprising a central air-conditioning system and an ultrafine particle purifying device. The ultrafine particle purifying device is arranged in an air flue of the central air-conditioning system, and comprises a fan, a purifying cavity with an air inlet and an air outlet, and an ultrafine particle filtering device. The ultrafine particle filtering device is arranged on the air inlet of the purifying cavity. The fan is arranged on the air outlet of the purifying cavity. An air-out direction of the fan is toward the downstream end of the air flue. The cross section of the air flue on the position where the ultrafine particle purifying device is in is shielded partially by the ultrafine particle purifying device, and an airflow channel is reserved for ventilation.

Description

Technical field [0001] The central air conditioning ultrafine particle purification device of the present invention belongs to the technical field of air purification, and specifically relates to a central air conditioning system using the ultrafine particle purification device and a method for air purification using the same. Background technique [0002] Atmospheric particulate matter can be divided into three categories according to its aerodynamic diameter: coarse particulate matter. ( <10 μm), fine particles ( <2.5μm), ultrafine particles ( <0.1 μm). [0003] PM2.5 refers to particles in the atmosphere with a diameter less than or equal to 2.5 microns, sometimes called lung particles. In most cases, the haze and haze that we often see are caused by pm2.5. Although the content of pm2.5 in the atmosphere is extremely small, due to its low quality, it carries viruses and harmful substances for a long time, has various transmission channels, and moves far away, which ca...

Problems solved by technology

In order not to affect the air volume and other performance of the central air conditioner, the power of the centrifugal fan must be greatly increased accordingly, thereby greatly increasing the energy consumption cost and noise of the air conditioning system, which is not conducive to energy saving and emission reduction, although it can degrade ultrafine particles once. The rate is relatively high, but at the cost of sacrificing the investment cost and energy consumption of the system
