A purification and antivirus system for central air-conditioning air inlet and return air outlet

Abstract

The invention relates to the technical field of air-conditioning equipment, and discloses a purification and anti-virus system for air inlets and return air outlets of central air conditioners, including a fan coil unit, and the fan coil unit is connected with a return air inlet, a fresh air inlet, an air supply port, and a fresh air Inlet, the air outlet of the fan coil unit is provided with a filter device. The purification and antivirus system for the air inlet and return air outlet of the central air conditioner uses a drying device to dry the incoming fresh air, and the dried fresh air is mixed with the return air and then filtered by an electrostatic purification device. On the one hand, the air is kept relatively dry. state, to ensure the effect of electric-level attachment and electrostatic adsorption, to ensure better disinfection and filtration of fresh air and cold air, on the other hand, to reduce the impact of low temperature and reduce additional energy consumption, and secondly, because the drying device dries the air , the humidity of the air flowing in the pipeline is low, so the phenomenon of condensing into ice is also less, which ensures the smooth flow of air in the pipeline and the replacement of turbid air in the room.

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.
