Problems solved by technology

[0003] The built-in LED disinfection lamp in the cab can disinfect the indoor air, but the outdoor air entering the room cannot be disinfected in time; at the same time, the LED disinfection lamp is placed in the car, which has radiation effects on the human body
Turning on the LED disinfection lamp for a long time can easily cause the local temperature of the indoor air to rise and even cause a fire hazard.
[0004] Spray alcohol (disinfection water) treatment: the human body endures the smell of disinfectant water and alcohol in a closed environment, and the experience is very poor. If the external circulation system of the air conditioning system is turned on, the outdoor air cannot be effectively sterilized when it enters the room

Embodiment 1

[0035] Internal circulation air sterilization: such as figure 2 As shown, the inner circulation damper 2 is opened, the outer circulation damper 1 is closed, and the air inlet of the air conditioner is the air in the cab. Air flow direction: indoor air → filter screen 4 → blower 3 → LED disinfection lamp 7 → airtight cavity 8 → evaporator 5 → air-conditioning air distribution structure blows to the human body in the cab. Control mode: keep the blower 3 turned on, and the LED disinfection lamp 7 is turned on, the air in the cab enters the airtight cavity 8 through the LED disinfection lamp 7, and the air is blown to the human body after a short stay in the airtight cavity 8 for sufficient disinfection. Control method: After turning on the LED disinfection light, the air volume of the blower is at the lowest wind speed, so that the air flow rate is slow and the air in the airtight cavity can be effectively sterilized. The air outlet temperature sensor detects the local temperat...

Embodiment 2

[0037] External circulation sterilization: such as image 3 As shown, the external circulation mode is the same as the internal circulation mode, only the damper is changed: the internal circulation damper 2 is closed, the outer circulation damper 1 is opened, and the air flow direction is: outdoor air→filter 4→blower 3→LED disinfection lamp 7→sealed cavity 8 → evaporator 5 → the air-conditioning air distribution structure blows to the human body in the cab.

Embodiment 3

[0039] Filter sterilization: After the filter is used for a long time, bacteria will grow on the surface, and the internal and external circulation air needs to pass through the filter. In order to improve the sterilization effect, this scheme designs a return air structure, and the air sterilized by ultraviolet rays flows to the filter screen to kill the filter screen.

[0040] Such as Figure 4 Shown: the internal and external circulation dampers are all closed, the air return damper 6 is opened, and the air forms a small circulation: filter screen 4 → blower 3 → LED disinfection lamp 7 → filter screen 4. After the filter screen 4 is sterilized, the air is sterilized, and some LED disinfection lights also reach the surface of the filter screen for double sterilization treatment. This mode is generally turned on for 2 to 3 minutes and then turned off to avoid the filter screen from being burned.

Abstract

An air-conditioning assembly structure with a sterilization function, including an outer circulation damper, an inner circulation damper, an air inlet cavity, a blower, a filter screen, and an evaporator, and is characterized in that: a There is an LED disinfection lamp, the LED disinfection lamp has two intersecting lamp surfaces, and the two lamp surfaces of the LED disinfection lamp can respectively shine on the filter screen and the surface of the evaporator; the blower is arranged above the side of the LED disinfection lamp, and the air It flows out from the air outlet of the blower and blows to the surface of the LED disinfection lamp; a return air damper is set between the air inlet cavity and the airtight cavity, when the return air damper is opened, the outer circulation damper and the inner circulation damper are closed, the air intake cavity A new air duct is formed with the blower and the airtight cavity. The invention adopts the LED disinfection lamp combined with the air conditioning system to sterilize the circulating air, which not only realizes the sterilization of the air in the cab, but also realizes the sterilization of the outdoor air of the cab, and can also sterilize the filter screen and the evaporator, which is safe and efficient.

Description

technical field [0001] The invention belongs to the air-conditioning technology of a cab of a commercial vehicle, in particular to an air-conditioning assembly structure with a sterilization function. Background technique [0002] The deterioration of the environment leads to the deterioration of the air quality inside and outside the car. To reduce the impact of the virus, the common way for drivers and passengers is to build an ultraviolet LED disinfection lamp in the cab to disinfect the air in the cab, or spray alcohol (disinfectant) for treatment. [0003] The built-in LED disinfection lamp in the cab can disinfect the indoor air, but the outdoor air entering the room cannot be disinfected in time; at the same time, the LED disinfection lamp is placed in the car, which has radiation effects on the human body. Turning on the LED disinfection lamp for a long time can also easily cause the local temperature of the indoor air to rise and even cause a fire hazard. [0004] ...
