Purification and disinfection system for air inlet and air return opening of central air conditioner

Abstract

The invention relates to the technical field of air conditioning equipment, and discloses a purification and disinfection system for an air inlet and an air return opening of a central air conditioner. The purification and disinfection system comprises a fan coil, the fan coil communicates with the air return opening, a fresh air inlet, an air supply opening and a fresh air inlet, and the air supply opening of the fan coil is provided with a filtering device. According to the purification and disinfection system for the air inlet and the air return opening of the central air conditioner, fresh air entering the system is dried through a drying device, and the dried fresh air and return air are mixed and then filtered through an electrostatic purification device, so that on one hand, the air is kept in a relatively dry state, and the electrode electricity attachment and electrostatic adsorption effects are guaranteed; and compared with the prior art, the fresh air and cold air are both well disinfected and filtered, on the other hand, the influence of low temperature is reduced, additional energy consumption is reduced, and in addition, as the drying device dries the air, and the humidity of the air flowing in a pipeline is low, the phenomenon that the air is condensed into ice is few, smooth flowing of the air in the pipeline is guaranteed, and replacement of turbid indoor air is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a purification and anti-virus system for central air-conditioning air inlets and return air outlets. Background technique [0002] When the temperature is high, indoor public places not only need to circulate ventilation, but also need to turn on the air conditioner for a long time to reduce the indoor temperature. In order to avoid the spread of viruses that may exist in the air, in some cases, all fresh air is used for circulation. However, due to indoor and outdoor Due to the large temperature difference, using all fresh air will greatly increase the energy consumption of the air conditioner. Therefore, disinfecting the return air of the air conditioner and adopting a mixture of fresh air and return air can effectively reduce the energy consumption of the air conditioner. [0003] There are many types of commonly used disinfection and sterilization devices. ...

Problems solved by technology

However, the particles are insulated when they are dry, but if the air humidity is high, the charging performance of the particles will be reduced, the charge carried by them will be reduced, and the dust removal effect will be reduced. In severe cases, it may not work. , rainy and snowy weather is more frequent, and at this time, the indoor hot air is mixed with the cold air of the fresh air, and the overall humidity increases, which will affect the efficacy of the electrostatic disinfection device. Significantly increase the use of air conditioners and the duration of room closures. Therefore, it is necessary to strengthen the disinfection ability in winter rainy and snowy weather

[0004] Secondly, when cold air enters in winter, the water vapor contained in it may condense in the pipe, resulting in a decrease in the flow capacity of the pipe.
