To be described in more detail, the air sucked inside the elevator car is converted into an evaporator. It is purified through a sterilizing filter unit before reaching the inside of the elevator car to prevent the inside of the elevator car from being contaminated by cold air supplied into the inside of the elevator car and to create a comfortable environment inside the elevator car. By measuring the internal temperature and humidity, not only can the temperature and humidity inside the elevator car be properly maintained, but also the amount of air supplied into the elevator car is adjusted according to the surrounding environment, such as the number of users, country, and season. This is a technical field related to modular elevator air conditioning systems equipped with a sterilization function to maintain appropriate temperature and humidity.

The housing 20 refers to an air conditioner, and the evaporator 30, evaporation fan 32, condenser 40, and condensation fan 42 are installed inside, and a compressor 50, which is a typical air conditioner, It will be obvious that an expansion valve 60 is provided.

To briefly explain the operation of the housing 20, that is, the air conditioner, that is, the flow of refrigerant, the compressor 50 compresses the low-temperature/low-pressure gas delivered from the evaporator 30 into high-temperature/high-pressure gas to form a condenser (40). ), and the condenser 40 cools the high-temperature/high-pressure gas delivered from the compressor with water or air, condenses it into a low-temperature/high-pressure liquid, and sends it to the expansion valve 60. The valve 60 converts the low-temperature/high-pressure liquid delivered from the condenser 40 into low-temperature/low-pressure liquid and sends it to the evaporator 30, and the evaporator 30 converts the low-temperature/high-pressure liquid delivered from the condenser 40 into low-temperature/low-pressure liquid. The low-temperature/low-pressure liquid absorbs heat and evaporates, and performs the function of sending the converted low-temperature/low-pressure gas to the compressor (50).

It is supplied so that it can be circulated back into the elevator car 10 through an outlet (not shown).

At this time, the air circulated inside the elevator car 10 by the evaporation fan 32, that is, cold air, is generally designed to be supplied to one side of the elevator car 10 so that it is not directly delivered to the user.

The condenser 40 is cooled by the air inside the housing 20 by the condensation fan 42 installed at the rear, and the heated air, that is, warm air, is discharged to the outside of the elevator car 10, which is the outside of the housing 20. make it possible

The condensation fan 42 allows air outside the elevator car 10 to be sucked into the interior of the housing 20. For this purpose, the housing 20 is provided with an elevator car 10 on the upper surface and the other side, respectively. ) An upper opening 26 and a side opening 22 through which external air can be sucked are formed.

Specifically, the housing 20 includes a side opening 22 formed through the other side, a second sterilizing filter part 24 installed in the side opening 22, and an upper opening formed through the upper surface ( 26) and a third sterilizing filter unit 28 installed in the upper opening 26, and the second sterilizing filter unit 24 and the third sterilizing filter unit 28 are subsequently Since it has the same configuration as the first sterilizing filter unit 200, which will be described in detail in , a detailed description will be given in the first sterilizing filter unit 200.

If it is composed of a general wide-angle lens or a concave lens, as shown in the drawing, respectively. Compared to a regular lens, ultraviolet rays are irradiated at a wider angle to sterilize the surfaces on which contaminants have accumulated in the air filter 220 and the HEPA filter. When composed of a convex lens, ultraviolet rays are irradiated at a smaller angle to the wide-angle lens. However, since ultraviolet rays can be concentrated, the effect of easy removal of contaminants, that is, viruses, can be achieved.

Image information installed inside the housing 20 and captured by the camera unit 300, that is, the thermal imaging camera 320, temperature and humidity measured by the first temperature and humidity sensor 400, and the second temperature and humidity It is characterized in that the wind volume, temperature, and humidity of the air supplied into the elevator car 10 are controlled based on the temperature and humidity measured by the sensor 500.

As described above, the control unit 600 of the present invention measures the temperature measured from the plurality of first temperature and humidity sensors 400 and transmitted to the control unit 600 when a plurality of first temperature and humidity sensors 400 are installed. and the humidity is calculated as an average value to determine the temperature and humidity inside the elevator car 10.

Accordingly, the control unit 600 of the present invention determines the difference between the temperature of the moving object measured by the thermal imaging camera 320 and the temperature measured by the first temperature and humidity sensor 400, and determines that the temperature of the moving object is the first temperature. If the temperature is greater than the temperature measured by the temperature and humidity sensor 400, the average temperature of the air inside the elevator car 10 is lowered by a preset value to make the inside of the elevator car 10 comfortable. The air volume and temperature of the cold air are controlled so that the initially set average temperature for keeping the interior of the elevator car (10) comfortable even as time passes, and the temperature of the moving object is measured by the first temperature and humidity sensor (400). In order to make the inside of the elevator car (10) comfortable, if the temperature is lower than the specified temperature, the average temperature of the air inside the elevator car (10) is raised by a preset value, so that the temperature inside the elevator car (10) remains at the initial level even over time. The amount and temperature of cold air are controlled to reach the set average temperature for making the interior of the elevator car 10 comfortable.

At this time, when the control unit 600 of the present invention cannot obtain image information from the thermal imaging camera 320 because there is no moving object, that is, when the temperature of the moving object is not measured, the initially set interior of the elevator car 10 is kept comfortable. The inside of the elevator car 10 is made comfortable by returning to the average temperature.

In addition, the control unit 600 of the present invention compares the humidity inside the elevator car 10 and the humidity of the cold wind from the first temperature and humidity sensor 400 and the second temperature and humidity sensor 500 to determine the humidity inside the elevator car 10. Controls the humidity of the cold air so as to reach the initially set average humidity for making the inside of the elevator car (10) comfortable, and this control of humidity controls the air volume and temperature inside the elevator car (10) and is controlled together. It will be self-explanatory.

That is, when the number of users increases, the control unit 600 of the present invention increases the amount of supplied air, that is, cold air, lowers the temperature, and lowers the humidity to create a comfortable environment inside the elevator car 10, When the number of people decreases, the amount of supplied air, that is, cold air, is reduced, the temperature is increased or maintained the same, and the humidity is increased or maintained the same to create a comfortable environment inside the elevator car 10.

In connection with the above, the control unit 600 of the present invention may be configured to include a storage unit 610 through which an operator can input and store the preset average temperature and average humidity information, where the storage unit 610 ) can additionally store not only the average temperature and average humidity, but also seasonal temperature and humidity information according to the country of use, temperature and humidity information by date, and temperature and humidity information by time zone.

Accordingly, the control unit 600 of the present invention stores temperature and humidity information by season, temperature and humidity information by date, and temperature and humidity information by time zone stored in the storage unit 610 by the worker, that is, surrounding environment information, and uses this as a basis. The wind volume, temperature, and humidity of the air supplied into the elevator car 10 are controlled so that the temperature and humidity inside the elevator car 10 can be maintained at a preset temperature and humidity, that is, the average temperature and average humidity.

In addition, since the average temperature and humidity maintained by season, date, and time zone are different for each country, that is, for each country, if there is a large difference between this average temperature and humidity and the preset temperature and humidity stored in the storage unit 610, the present invention Since the elevator air conditioner system may operate harshly, that is, excessively, shortening its lifespan, the average temperature and humidity close to the average temperature and humidity maintained by season, date, and time for each country are stored in the storage unit 610.

That is, the control unit 600 of the present invention stores the temperature and humidity information by season according to the country of use, the temperature and humidity information by date, and the temperature and humidity information by time in the storage unit 610, and then uses the camera unit 300 described above and the first temperature and humidity information. By comparing and determining and controlling the information measured by the sensor 400 and the second temperature and humidity sensor 500, it is possible to more efficiently create a comfortable environment inside the elevator car 10.

In other words, the control unit 600 of the present invention stores the average temperature and average humidity inside the elevator car 10 maintained according to the surrounding environment in the storage unit 610, and uses the previously described camera unit 300 and By comparing the information measured by the first temperature and humidity sensor 400 and the second temperature and humidity sensor 500 to control the air volume, temperature and humidity of the air supplied to the inside of the elevator car 10, that is, the temperature and humidity, more efficiently. This achieves the effect of creating a comfortable environment inside the elevator car (10).

As a result, the elevator air conditioner system of the present invention purifies and sterilizes the internal air and external air of the elevator car 10 circulated through the sterilizing filter unit, thereby creating a comfortable environment inside the elevator car 10. Of course, the effect of creating a more comfortable environment can be achieved by automatically controlling the air volume, temperature, and humidity of the air supplied inside the elevator car 10 according to the number of users and the surrounding environment, that is, the amount of cold air, and the humidity.
