Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to an air conditioning unit with disinfection function. Background Technology

[0002] An air conditioning fresh air handling unit is an air conditioning device that provides fresh air. Its working principle is to draw in fresh air from outdoors, process it through dust removal, dehumidification (or humidification), and cooling (or heating), and then deliver it indoors via a fan, replacing the existing indoor air. As the most important component of an air conditioning ventilation system, the air handling unit's ability to provide disinfection is crucial. Traditional air handling units can only sterilize the incoming air, failing to effectively disinfect internal components such as filters, cooling coils, heaters (humidifiers), and condensate pans. This results in the retention of a large number of germs within the unit. Furthermore, the temperature and humidity inside the air handling unit easily promote the proliferation and accumulation of germs, which are then re-introduced into the room with the fresh air, causing more serious secondary pollution and posing a certain degree of threat to people's health.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] In the description of the utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0020] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] Example 1: As shown in the figure, this utility model includes an air conditioning unit body, a centrifugal fan 3 installed inside the air conditioning unit body, a filter assembly, an electric preheater 4, an air heat exchanger 5, a dry steam humidifier 7, and a disinfection assembly installed on the air conditioning unit body. An air inlet section 10 and an air outlet section 15 are respectively provided at both ends of the air conditioning unit body. In this example, the electric preheater 4 and the dry steam humidifier 7 are located on both sides of the air heat exchanger 5. The air heat exchanger 5 is externally connected to the air conditioning unit body via a cold / hot water pipeline 14, which is connected to the cold / hot water pipeline 14 through a cold / hot water inlet and a cold / hot water outlet. The dry steam humidifier 7 is externally connected to the air conditioning unit body via a steam delivery pipeline 16.

[0022] The disinfection assembly includes an ultraviolet lamp disinfection module and a hydrogen peroxide disinfection module 13. The ultraviolet lamp disinfection module is located inside the air conditioning unit, and the hydrogen peroxide disinfection module 13 is connected to the air conditioning unit. Furthermore, the filtration assembly includes a coarse filter 1, a medium-efficiency filter 2, and a sub-high-efficiency filter 8. The coarse filter 1 and the medium-efficiency filter 2 are located near the air inlet section 10, and the sub-high-efficiency filter 8 is located near the air outlet section 15. Specifically, in this example, the coarse filter 1, the medium-efficiency filter 2, the centrifugal fan 3, the electric preheater 4, the air heat exchanger 5, the dry steam humidifier 7, and the sub-high-efficiency filter 8 are sequentially arranged inside the air conditioning unit. A temperature and humidity sensor 11 and an anti-freeze protector 6 are also installed inside the air conditioning unit to ensure stable operation of the device.

[0023] The device in this application is connected in a horizontal assembly manner, with all components installed on the same common base frame and adopting a press-out structure. The electrical control system is integrated into the air conditioning electrical control box 9.

[0024] Example 2: Based on the technical solution disclosed in Example 1, preferably, the ultraviolet disinfection module includes ultraviolet disinfection lamps 12, of which multiple sets are provided. LED lights are also installed inside the air conditioning unit. Under normal operating conditions, the airflow is sterilized by ultraviolet lamp irradiation. The principle of ultraviolet sterilization is adopted; the strongest ultraviolet sterilization wavelength is 250-270nm, which can prevent some germs from being transmitted through the air or through object surfaces, thus achieving the purpose of sterilization.

[0025] In addition, the hydrogen peroxide disinfection module 13 is used to vaporize hydrogen peroxide and deliver the gaseous disinfectant into the air conditioning unit. Normally, the ultraviolet light generated by the ultraviolet lamp disinfection module disinfects the flowing air. In emergencies, the hydrogen peroxide disinfection module 13 disinfects internal components such as filters, surface coolers, heaters (humidifiers), and condensate pans within the air conditioning unit. The hydrogen peroxide disinfection module 13 employs vaporized hydrogen peroxide (VHP) biological sterilization technology, and the unit has a reserved disinfection interface. During disinfection, all air inlet and outlet valves of the air conditioning unit with online disinfection function are closed, completely disconnecting it from the ventilation system. Gaseous disinfectant (vaporized hydrogen peroxide) is generated within the hydrogen peroxide disinfection module 13. Under the action of the disinfection machine, the gaseous disinfectant circulates and penetrates all sections within the air conditioning unit, thereby achieving thorough disinfection of the interior of the unit.

[0026] This utility model has a scientific and reasonable structural design that is easy to implement. It adopts a composite disinfection technology of ultraviolet lamp disinfection module and hydrogen peroxide disinfection module, which can not only disinfect the flowing air, but also disinfect the internal structural components of the air conditioning unit. It effectively eliminates the germs attached to the inside of the air conditioning unit, prevents secondary pollution from the device, and effectively protects people's health. It has good application and promotion value.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
