Description

Technical Field

[0001] The present invention relates to the field of elevator disinfection, and in particular to an elevator disinfection ventilation and air-conditioning system and an operation method thereof. Background Art

[0002] As a vertical transportation tool in buildings, elevators have become an integral part of people's lives. For common box-type elevators, the elevator shaft is usually a closed space, and the elevator car is installed inside the shaft. Due to the limitations of the building structure, there are the following problems:

[0003] 1. Poor air quality in the elevator car. Since there is no unified standard for air quality and ventilation in the elevator car, the air in the existing elevator car mainly relies on forced ventilation with the air in the shaft. Since the air in the elevator shaft has odors such as oil and rust, and is accompanied by a large amount of flocculent matter and dust, it enters the car without being filtered. At the same time, affected by the season, people often feel hot or cold. In addition, with the regulations on garbage classification and delivery time, the odor in the car caused by domestic garbage is difficult to eliminate quickly, which greatly reduces the riding comfort.

[0004] 2. There is a lack of disinfection facilities in the elevator cabin. Due to the structural limitations of the elevator and the concentration of people using it, the droplets carrying the virus in the cabin will not only directly infect the passengers at the same time, but also enter the air in the shaft through forced ventilation and then re-enter the cabin to form long-term secondary pollution. The existing prevention and control measures for elevator cabins are mainly flow control, configuration of non-contact rapid hand disinfectant and (or) sanitary paper towels, surface disinfection, daily cleaning, etc., and enhanced ventilation, but the effect is not satisfactory.

[0005] 3. Elevator use forms an information island. Users have no way of knowing the number of people in the elevator car they are about to take, the air quality, whether there are virus carriers such as high fever and coughing, etc., and cannot choose whether to take the elevator on their own, and can only passively bear it. Existing users have no way of knowing the air quality, whether there are virus carriers such as high fever and coughing, etc. encountered in the later use of the elevator, and cannot choose whether to continue taking the elevator on their own, which greatly increases the chance of infection.

[0006] 4. Due to the chimney effect, the air in the elevator shaft will flow upward along the space of the shaft, causing a pressure difference between the shaft and the outside of the elevator hall, which will lead to enhanced air convection at the elevator hall door, causing noise and the inability to close the hall door, which will aggravate the spread of fire when a fire occurs.

[0007] In order to solve the problems in actual operation, people have made various attempts. The patent with application number CN202110059444.2 proposes a ventilation and filtering elevator. By ventilating the car and the ventilation interlayer formed above and below the car, the resistance during the operation of the car can be reduced and the ventilation effect can be improved. However, in this invention, the air flow direction in the car changes during the upward and downward movement of the elevator, and the virus droplet transmission and disinfection are not involved. At the same time, the ventilation problem of the car when the elevator is stationary cannot be solved. The patent with application number 202210846657.4 proposes an elevator car air disinfection system, which uses a low-temperature plasma disinfection component installed between the air disinfection boxes to disinfect the car air, which has a certain effect, but this invention does not consider the piston wind when the elevator is running at high speed, and its air intake and exhaust functions are affected. The patent with application number CN202210209451.0 proposes an epidemic prevention elevator system that forms a linkage structure between the elevator hall door and the thermal imaging camera through a transmission component, which can realize multi-angle monitoring of the thermal imaging camera, and only proposes an early warning and cannot achieve disinfection.

[0026] An operating method of an elevator disinfection ventilation and air conditioning system comprises the following steps:

[0027] Step 1: Set the temperature Tj in the elevator car to the range of (T1, T2), the wind speed Uj to the range of (U1, U2), and the CO2 concentration Nj to the range of N max , TVOC threshold M max , the threshold H of bacterial and viral pathogens tested by nucleic acid biosensors max , the threshold value of the sound level meter sensor (x max ,y max 、z max ), where x max Indicates the maximum value of the RMS value of the cough sound, y max Indicates the maximum value of the cough sound frequency, z max Indicates the duration of a coughing attack; sets the elevator static time threshold TP0;

The control processing device receives information from the temperature sensor and turns on the circuit controller, so that the positive electrode of the battery is connected to the P-type semiconductor and the first metal heat-conducting plate, and the negative electrode is connected to the N-type semiconductor and the first metal heat-conducting plate. Under the action of the electric field, the temperature of the nodes between the P-type semiconductor and the N-type semiconductor on the inner side of the building envelope and the first metal heat-conducting plate is increased by utilizing the difference in temperature between the indoor and outdoor of the building. Under the action of radiation, the air temperature in the elevator shaft is increased;
