Description

[Detailed description of the invention] <Industrial application field> This invention can control the temperature and humidity of air taken in from outside and indoors, and can also sterilize the air using an internal germicidal lamp. Regarding air conditioning equipment.

<Conventional technology> Outside air and indoor air such as clean rooms are taken into air conditioning equipment, where the temperature and humidity are controlled, and filters are used.
For example, the air is purified by being supplied again through a high-performance filter called a HEPA filter. However, at this time, although some bacteria, such as bacteria attached to dust, are removed by a filter, many bacteria pass through and are supplied into the room along with the air.

In this way, conventional air conditioning equipment performs a certain amount of sterilization processing but does not perform sterilization processing. had been sterilized.

〈Problem that the invention aims to solve〉 However, bacteria can be removed by filters installed for sterilization.
Alternatively, it breeds in the humidifier water and drain pans in the air conditioning equipment, and is also contained in the outside air taken into the air conditioning equipment, so it enters the room one after another. Therefore, conventional air conditioning equipment does not keep the room in a truly sterile state, and on the contrary, air-conditioning equipment may cause airborne infections within the building.

<Means for solving the problem> The present invention was devised to solve the above problem, and by installing a germicidal lamp in the air conditioning equipment, it is possible to temperature-regulate and control the air taken in from outside and indoors. This is a sterilizing air conditioning system that humidifies the air and sterilizes the air and places where bacteria breed, and then supplies the air back into the room.

<Example> Hereinafter, an example according to the present invention will be described based on the drawings.

FIG. 1 is a schematic diagram of main parts showing a first embodiment of the present invention. As shown in the figure, inside the sterilizing air conditioning equipment 1, more specifically, inside the air conditioner 11 that constitutes the air conditioning equipment 1, there is a HEPA filter 11a and a cooling/heating coil 1.
1b and a humidifier 11c are provided, and a plurality of germicidal lamps 2 are disposed in the ventilation path and on the upper side of the HEPA filter 11a, the cooling/heating coil 11b, and the humidifier 11c so as to be perpendicular to the ventilation path. ing.

Furthermore, the HEPA filter 11a on the lower side
and the cooling and heating coil 11b, between the cooling and heating coil 11b.
A germicidal lamp 2a is arranged between the humidifier 11c and the humidifier 11c.

On the other hand, a reflector plate 3 is attached to the inner wall of the ventilation path in which the plurality of germicidal lamps 2 on the upper side are arranged.

Air from the room and outside taken in through the return air duct 12 and the outside air duct 13 is vented from the upper side of the ventilation path to the lower side.

On the upper side, the sterilizing lamp 2 is arranged perpendicular to the ventilation path, so that the air is evenly sterilized.

At this time, the reflection plate 3 attached to the inner wall provides a greater sterilization effect.

Furthermore, the HEPA filter 11a, the cooling/heating coil 11b, and the humidifier 11c themselves are connected to the germicidal lamp 2a between them.
They are constantly sterilized and do not contaminate the air that passes through them.

As described above, the air that has been sterilized on the upper side is supplied into the room through the HEPA filter 11a, the cooling/heating coil 11b, and the humidifier 11c, while maintaining the sterilizing effect or having a new sterilizing effect. It turns out.

On the other hand, the germicidal lamps 2a, 2a... emit low-density ultraviolet rays of about 100 μW/cm ² for a long time.
Propagation of bacteria in the humidifier 11c and the drain pan 11d installed below them is prevented.

FIG. 2 is an example of further sterilizing the sterilized air. As shown in the figure, the germicidal lamps 2, 2 and the reflector plate 3 are provided inside the air outlet unit 16 constituting the germicidal air conditioner 1, for example, on the inner wall of the chamber 16a. This air outlet unit 16 connects the air supply duct 15 and the indoor air outlet 17, and the temperature- and humidity-controlled air supplied into the room is further supplied to the air from the germicidal lamp 2 installed here. Sterilization treatment is performed by dense ultraviolet irradiation and light reflected by the reflection plate 3.

FIG. 3 explains an example different from the example shown in FIG. 2. As shown in the figure, the sterilizing lamp 2 and the reflector 3 are connected to the air supply duct 15 that constitutes the sterilizing air conditioning equipment 1.
More specifically, it is provided on the inner wall of the duct unit 15a forming the air supply duct 15.
Therefore, the temperature- and humidity-controlled air supplied into the room is further sterilized by high-density ultraviolet irradiation from the sterilizing lamp 2 provided here and reflected light from the reflector plate 3.

<Effects> As mentioned above, the sterilizing air conditioning system of the present invention can sterilize both the outside air and the air taken in from indoors, so by operating the air conditioning system, the entire building can be sterilized. This can prevent airborne infections and mold growth. Furthermore, since the sterilization process is carried out intensively in the narrow space inside the air conditioning equipment, the effects on the human body, which would be a problem if a sterilization lamp is installed indoors, are prevented and the cost required for the sterilization process is reduced.

Furthermore, in the case of the second and third embodiments, the existing air conditioning equipment can be replaced with a sterilizing type air conditioning equipment, and in combination with the first embodiment, the air supply duct can be branched from one air conditioner. In air conditioning equipment that supplies air to multiple rooms, it is also possible to increase the degree of sterilization in a specific room or system. Furthermore, by changing the irradiation density of ultraviolet rays, it is possible to change the sterilizing effect and create sterilizing air conditioning equipment according to the application.
