Problems solved by technology

However, the existing building air conditioning systems generally do not have disinfection and sterilization functions.
A small number of existing technologies adopt disinfection devices near the air inlet or air outlet of the central air conditioner, but they are not actually used. On the one hand, because the air circulation speed in the ventilation duct is very fast, the virus in the passage air is difficult to eliminate, and the disinfection effect of these devices Not obvious, on the other hand, the air inlet and outlet are located on the ceiling of the room, the installation space of the sterilization device is limited, and it is easy to reduce the air quality entering the room. These technologies are abandoned by building managers

no. 1 example

[0044] The building air conditioning disinfection system is suitable for multi-storey buildings. The building air conditioning system has an air handling unit (not shown) and air delivery ducts. The air handling device adopts a refrigeration cycle system in the prior art, specifically a water cooling unit. The treatment of air by the air handling device includes cooling or heating the return air, humidifying or dehumidifying, extracting air to introduce fresh air, accelerating pipeline air circulation, and so on. Air delivery ducts carry chiller cooled or heated air into building rooms. Air delivery ducts have fans at different nodes.

[0045] The disinfection system of this embodiment has a very high ability to eliminate germs, and is especially suitable for air conditioning systems during epidemics of airborne infectious diseases. Such as figure 1 As shown, there are several high-rise compartments 20 in the upper floors of the building, and several lower-floor compartmen...

[0055] In this embodiment, the building air-conditioning disinfection system is suitable for multi-floor buildings. The building air conditioning system has an air handling unit (not shown) and air delivery ducts. The air handling device adopts a refrigeration cycle system in the prior art, specifically a water cooling unit. The treatment of air by the air handling device includes cooling or heating the return air, humidifying or dehumidifying, extracting air to introduce fresh air, accelerating pipeline air circulation, and so on. Air delivery ducts carry chiller cooled or heated air into building rooms. Air delivery ducts have fans at different nodes.

[0056] The disinfection system of this embodiment has a very high ability to eliminate germs, and is especially suitable for air conditioning systems during epidemics of airborne infectious diseases.

no. 3 example

[0069] Such as Figure 4Shown is the third embodiment of the present invention, and a wind speed sensor 6 is also arranged on the wall 4 of the free radical chamber. There are four wind speed sensors 6, which are adjacent to the concentration sensors 2 on the top wall and the bottom wall. There are two top walls and bottom walls. The concentration sensor 2 and the wind speed sensor 6 are connected to the electric control device, and the electric control device adjusts the power of the free radical generators 3A and 3B and the fan of the building air conditioning system according to the free radical concentration measured by the concentration sensor 2 and the wind speed sensor 6 and the wind speed in the free radical chamber speed. Preferably, the fan installed in the air duct of the free radical chamber 1 is adjusted.

Abstract

The invention discloses a building air-conditioning disinfection system and a control method thereof, wherein the air conveying pipeline has inter-floor communicating pipes and room conveying pipes, and the inter-floor pipes connect different floors with air; a high-voltage pulse electric field chamber is connected to communicate between the floors. On the pipeline, the electric field in the high-voltage pulse electric field chamber is generated by a high-voltage pulse generator, so that the electric field in the chamber is kept within a predetermined range of electric field strength. The system effectively prevents the spread of viruses between different floors, and is especially suitable for building air conditioning during epidemics.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a building air conditioner disinfection system and a control method thereof. Background technique [0002] For the air conditioning system of buildings (such as office buildings and hospitals), the ventilation ducts between different floors and different rooms are generally connected to each other to facilitate the distribution of air volume of the air conditioning system. When the system is running, the fan sends the cold air formed by the water cooling unit to each floor, and the air will be exchanged between each floor and each room. And the existing building air-conditioning systems generally do not have disinfection and sterilization functions. A small number of existing technologies adopt disinfection devices near the air inlet or air outlet of the central air conditioner, but they are not actually used. On the one hand, because the air circulation speed in the ventilation ...
