Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sterile air conditioning method for controlling the atmosphere in a room, particularly in a hospital room, and its purpose is to circulate and maintain the temperature and humidity in the room at an optimal state, and to circulate sterilized air. The aim is to provide a hospital room environment with a favorable atmosphere.

Hereinafter, one embodiment of a sterilizing air conditioner that achieves the present invention will be described with reference to the drawings.

Reference numeral 1 indicates a hospital room, and reference numeral 3 indicates an air conduit, in which air within the hospital room 1 is drawn out by a fan F and delivered to a first cyclone 4.

Before that, the surplus air is discharged from the surplus air discharge port 3-1. The cyclone 4 is equipped with a steam pipe 5, and the cyclone 4 separates and purifies solid matter such as garbage that comes from the patient room 1, and the steam pipe 5 blows out steam to sterilize the air from the patient room 1. do. The air from which dust and the like have been removed by the cyclone 4 is introduced into the spray cooler 6 through the conduit 3'. The spray cooler 6 has a cyclone 4 on the side.
The air conduit 3' that communicates with is opened, the upper reflux pipe 7 is fixed open, and a cold water pipe 8 is installed around the reflux pipe 7 in the spray cooler 6. Mouth 9a
, 9b, 9c, . A large amount of cold water cooled to a predetermined temperature is always stored in the cold water tank 10, and the cold water is ejected as small droplets from the spray ports 9a, 9b, 9c, . . . via the pump P. Therefore, the air entering the spray cooler 6 comes into contact with the water droplets from the spray ports 9a, 9b, 9c, etc., and exchanges heat quickly and efficiently. is humidified and saturated at a temperature approximately equal to the cold water temperature, and exits from the reflux pipe 7. On the other hand, the water that has been deprived of heat dissolves or suspends odors, dust particles, etc. in the hospital room, and is not suitable for repeated use, so it is passed through the conduit 11 to the filter 12, filtered, and then passed through the conduit 11'. Return to cold water tank 10. For this reason, it is preferable that the filter 12 is a normal filter with an adsorbent material such as activated carbon, silica, acid clay, or ion exchange resin layered thereon to form a filtration surface. In this way, the air is cooled and saturated with humidification. The cooled air leaving the spray cooler 6 still contains some droplets and is damp, so it is completely dehydrated by the second cyclone 13. Therefore, only the dehydrated air with saturated humidity returns to the hospital room 1 through the return pipe 7''. Reference numeral 14 is a steam pipe, the end of which is opened to the cyclone 13, and the steam is transferred to the third pipe as needed. The circulating air is blown in through the cyclone 21, heated, and sterilized the hospital room 1 and piping through the return pipe 7''. Further, 15 is a compressor for cooling water, 16 is a cooler for the gas discharged from the compressor 15, and 17 is a conduit that cools the water in the cold water tank 10. Further, symbols Al and A2 are temperature detectors installed in the hospital room 1, Bl and B2 are humidity detectors, C is a temperature detector in the cooling water tank 10, and temperature detectors Al and A are temperature detectors installed in the fan F.
Temperature detector C is electrically coupled to the compressor 15 (not shown). In addition, humidity detector Bl,
B2 simply detects the indoor humidity. steam pipe 1
4 is connected to a third cyclone 21, which removes water droplets from fresh steam introduced through a valve from its side opening and allows only the steam to enter the second cyclone 13. do.

That is, the third cyclone 21 is for heating and humidifying with steam when the outside air temperature is low. A conduit 20 is further connected to the second cyclone 13, and the conduit 20 can send sterilized heated dry fresh air to the second cyclone 13 through a filter 19 and a heat sterilizer 18. The heat sterilizer 18 is a heating device that can indirectly heat with steam or other heating methods, and can also be referred to as an indirect heat exchanger, and serves to heat the outside air when the outside air is low. That is, when the outside air temperature is as low as around 20°C, new air that has been heated and sterilized at 1000°C to 110°C by the heat sterilizer 18 is introduced to adjust the temperature. When the sterilizing air conditioner is operated, the compressor 15 is operated to lower the water in the cold water tank 10 to a predetermined temperature.

When the temperature drops to a predetermined temperature, the switch of the compressor 15 is opened and stopped by a command from the temperature detector C, and when the temperature rises, it is closed and operated to perform ON/OFF control. The hospital room 1 is closed and the fan F1 and pump P are operated. For this reason, the air in the hospital room 1 is controlled by the first cyclone spray cooler 6,
After passing through the second cyclone 13, it is sterilized, purified, and cooled, and the hospital room 1
Reflux within. When the temperature in the hospital room 1 falls to a predetermined temperature, the temperature detectors Al and A2 detect this and stop the fan F.
Or control the rotation speed. Therefore, the inside of the hospital room is always kept at the optimum temperature and relative humidity. As a result, the room can maintain a suitable temperature and humidity range, and can be kept clean and sterile at all times.

The present invention is not limited to the management of hospital rooms, but can be widely used to control the indoor atmosphere of buildings, etc. In addition to the above advantages, the present invention can increase the rotational speed of the fan F1 and the pump P to quickly circulate cooling air. It is possible to cool the stored items in a short time, and it is also possible to sterilize the inside of the chamber 1 by stopping the pump P and blowing out steam from the steam pipe 14 and transporting it by circulating air. Since the air is purified, the air becomes clean, and the odor generated indoors is deodorized by cold water, so that no odor accumulates in the room and the transfer of fragrance is prevented.

In addition, since cold and hot water is always stored in the cold water tank 10, it can be used in urgent situations and does not require a particularly large compressor, which not only saves capital investment but also consumes less electricity. It has many advantages such as less heat loss.
