Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide an air conditioner that can remove bacteria and obtain any temperature and humidity.

More specifically, it is an object of the present invention to provide a sterilization air conditioner that adjusts the air optimally for rooms such as hospital rooms, operating rooms, sterile workplaces, fresh food processing plants, and fresh food storage rooms.

The next purpose of the present invention is to remove bacteria from the room air,
To provide a sterilizing air conditioner that removes odors and adjusts air to a desired temperature and humidity.

The present invention circulates air from a room and sends it to a water spray cyclone, where the air is sprayed with water to remove odors, separate garbage, remove bacteria and obtain humid air, and then heat the air. It relates to a sterilization air conditioner that sends water to an exchanger, removes water droplets there, and adjusts the temperature.

The rooms include all types of rooms, including hospital rooms, operating rooms, sterile work areas, general housing, fresh food processing facilities, and fresh food storage rooms.

Hospital rooms, operating rooms, sterile workplaces, general housing, etc. must be sterilized, deodorized, and the air must be at 22-25 degrees Celsius and 50-70% humidity, and fresh food processing areas, fresh food storage rooms, etc. must be sterilized. The air must be heated, deodorized, and at a temperature of 0 to 18°C and a humidity of 70 to 100%.

In the present invention, air having such a desired temperature and desired humidity can be produced extremely easily. That is, by setting the temperature of the water sprayed by the water spray cyclone at 0 to 90°C and spraying any water between them, air with a saturated humidity of 0 to 98°C can be obtained. If this air is sent to a heat exchanger and heated, the humidity will decrease as the temperature increases, and if it is cooled, it can be made into air at a desired temperature with saturated humidity. Therefore, as long as you calculate the desired temperature and humidity in advance and specify the temperature of the sprayed water and the temperature inside the heat exchanger, you can easily produce air at the desired constant temperature and humidity. can be obtained.

In the water spray cyclone of the present invention, air remains while rotating for a long time and is sprayed with water at a temperature of 0 to 98 degrees Celsius, so dirt, bacteria, and odors brought from indoors are removed and the air is brought close to saturated humidity. Can be done.
A sterilizing cyclone can be installed between the chamber and the water spray cyclone, and high-temperature steam can be sent there to kill bacteria.

The heat exchanger according to the present invention is preferably provided with temperature regulating medium conduits arranged one to five times, preferably two to three times, inside the can. As a temperature adjustment medium, 0~
Water at 80 DEG C., preferably 0 DEG to 40 DEG C., may be used, and inside the can, saturated humid air is in contact with this 0 DEG to 80 DEG C. temperature conduit for a long period of time, during which time the desired temperature is adjusted. Excess water droplets can be removed by centrifugal force during rotation and retention within this cyclone.

If necessary, a water removal droplet cyclone can be provided between the water spray cyclone and the heat exchanger to remove water droplets.

The chamber, water spray cyclone, and heat exchanger are sequentially connected by circulation pipes, so that air is circulated throughout.

To explain the present invention with drawings, 1 is a chamber, 3 is an air conduit, and the air in the chamber 1 is drawn out by a fan F and blown into the water spray cyclone 6 through conduits 3' and 3''.Before that, Surplus air is exhausted from the surplus air outlet 3-1.If necessary, it is passed through a sterilizing cyclone 4, which is equipped with a steam pipe 5, which blows out steam to remove the air from the chamber 1. The air is sterilized. It is then passed through conduit 3'' into water spray cyclone 6. The water spray cyclone 6 opens an air conduit 3'' communicating with the cyclone 4 on the side, and fixes an upper recirculation pipe 7 open.
A water pipe 8 is placed around the return pipe 7 in the water spray cyclone 6.
is installed, and a large number of spray ports 9a, 9b are attached to this water pipe 8.
..., and these spray ports are connected to a water spray cyclone 6.
The water pipe 8 is opened inward and communicates with a water tank 10. The water tank 10 is always kept at a predetermined temperature of 0.
A large amount of water adjusted to ~98°C is stored, and the water is ejected as small droplets from spray ports 9a, 9b, . . . via a pump P. Therefore, the air entering the water spray cyclone 6 comes into contact with water droplets from the ejection pipes 9a, 9b, etc., quickly and efficiently exchanging heat, adjusting the temperature to a predetermined temperature, and at the same time eliminating odors, small particles, and bacteria. is removed by attaching it to the cyclone wall together with water droplets,
The air is saturated at a temperature approximately equal to that of water and exits from the reflux pipe 7.

On the other hand, the sprayed water dissolves or suspends indoor odors, dust particles, bacteria, etc., and is not suitable for repeated use, so it is passed through the conduit 11 to the filter 12, filtered, and the water is passed through the conduit 11'. Return to tank 10. For this reason, it is preferable that the filter 12 is a normal filter with a filter surface layered with an adsorbent such as activated carbon, silica clay, acid clay, or ion exchange resin. In this way, the air is saturated and humidified at a low temperature. or,
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 water tank 10. Moreover, when heating water, a heater (not shown) may be set.
Further, the cooling device and the heater may be set at the same time. Further, symbols A ₁ and A ₂ are temperature detectors installed in the room 1, B ₁ and B ₂ are humidity detectors, and C is a temperature detector in the cooling water tank 10.
A ₁ and A ₂ are electrically coupled to the unillustrated power of the fan F, and the temperature detector C is electrically coupled to the compressor 15 or the heater.

The saturated humid air leaving the water spray cyclone 6 still carries some droplets with it.

This saturated humid air is sent to the heat exchanger 101 via the reflux pipes 7 and 7', where water is completely removed and the temperature is adjusted. If necessary, the saturated humid air is guided from the reflux pipe 7 to the pipe 20 branched off, passing through the drip removal cyclone 21, excess water droplets are removed by the centrifugal force of the cyclone, and then the air is passed through the pipe 20'.
can be led to the reflux pipe 7'.

The saturated humid air is passed from the reflux pipe 7' to the heat exchanger 101.
