DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sterile temperature and humidity control device that maintains the temperature and humidity in a room such as a hospital room at an optimal state, and circulates and maintains the atmosphere in the room in a sterile state.

. In particular, the object of this invention is to provide a temperature and humidity control device in which a plurality of cyclone type spray Java coolers are sequentially arranged in series in an air circulation circuit. To provide a sterilization temperature and humidity control device capable of controlling temperature with sufficient efficiency and excellent accuracy.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, arrows indicate the direction of fluid flow. Number 1 generally indicates a room such as a hospital room, and air in the room 1 is sucked into the first cyclone 4 through an air conduit 3 connected tangentially around the first cyclone 4 .

A steam pipe 5 is connected to the first cyclone 4,
Solid matter such as dust and dirt entrained from the chamber 1 is separated by the first cyclone 41C and discharged through the valve 22, thereby purifying the air.

In addition, steam is blown in from the steam pipe 5 to sterilize the air from the chamber 1.

Air that has been purified and sterilized by removing dust and the like by the cyclone 4 passes through a conduit 3 extending above the cyclone 4, is sucked out from the cyclone 4 by a fan F, and is blown into a cyclone-type spray Java cooler 6.

Cyclone type: The spray Java cooler 6 communicates with the air conduit 3 which communicates with the cyclone 4 in the tangential direction of the circumference, and connects and fixes a reflux pipe 7 extending upward, so that the reflux inside the cyclone type spray Java cooler 6 A cold water pipe 8 is arranged around the pipe 1.

This cold water pipe 8 has many spray ports 9ay9b, 9c...
These spray ports are opened into the cyclone type spray Java cooler 6, and the cold water pipe 8 communicates with the cold water tank 10. The cold water tank 10 is always filled with cold water cooled to a predetermined temperature. A large amount of cold water is stored, and the cold water is sent to the cold water pipe 8 by a pump P, and its spray port 9a
, 9b, 9c... are sprayed in smaller droplets in a Java-like shape.

The air that has entered the cyclone-type spray Java cooler 6 comes into contact with water droplets from the spray ports 9a, 9b, 9c, etc., undergoes heat exchange quickly and efficiently, and is condensed into excess water due to cooling, which removes water. It is humidified to compensate for the lack of moisture, becomes saturated at a temperature approximately equal to the cold water temperature, and is sent out from the reflux pipe 1.

Water from which heat has been removed VC//'i Since particles such as odors and dust in the room are dissolved or suspended, the water passes through the conduit 11 and enters the filter 12 where it is filtered and then flows through the conduit 11 into the cold water tank 10. be returned.

Therefore, the filter 12 is a normal filter with a layer of adsorbent such as activated carbon, diatomaceous earth, acid clay, or ion exchange resin.
It is preferable to have a filtration surface.

As mentioned above, the air is saturated and humidified at low temperatures.

The air exiting the cyclone type spray Java cooler 6 is sent to the cyclone type spray Java cooler 6 through the reflux pipe 7.

The reflux pipe 7 opens into the cyclone-type atomized Java cooler 6 in a tangential direction around its periphery.

The cyclone type spray Java cooler 6 has a similar structure to the cyclone type spray Java cooler 6, and parts that are the same as the cyclone type Java cooler 6 are designated by the same numbers, and the numbers are indicated with a prime symbol (a suffix).

Since the function of the cyclone type spray Java cooler 6 is similar to that of the cyclone type spray Java cooler 6, the description thereof will be omitted here.

Although only two cyclone type spray Java coolers are shown in the drawing, several more cyclone type Java coolers can be sequentially arranged as desired.

Here, the air is sterilized and kept at a constant temperature, for example, 18° C. and saturated humidity, and is kept in a basic state that can be easily adjusted to any temperature and humidity.

Since the cooled and humidified air leaving the last-arranged cyclone type spray Java cooler still contains some droplets, it is completely dehydrated by the second cyclone 13.

Therefore, only the optimally humid air that has been dehydrated returns to the chamber 1 through the reflux pipe 2.

vapor. One end of the pipe 14 will be opened to the second cyclone 13.
If necessary, steam is blown in through the cyclone 21 to heat the circulating air, or into the chamber 1 through the reflux pipe 2. The entire equipment and piping can be sterilized.

Output from cooling water cooling compressor 15, 15. The collected gas passes through a condenser 16, 16 and an expansion valve (not shown) to cool the water in the cold water tanks 10 and 10'.

The steam pipe 14 is connected to the third cyclone 21,
The third cyclone 21 is configured to remove water droplets from the new air and allow only steam to enter the second cyclone 13.

That is, the third cyclone 21 is used not only to perform the sterilizing action as described above, but also to heat and humidify with steam when the outside temperature is low.

A conduit 20 is further connected to the second cyclone 13 and can feed fresh air into the second cyclone 13 through a filter 19 and a heat exchanger 18.

The heat exchanger 18 is a heating device that can be heated indirectly by steam or other heating methods, and serves to heat the outside air when the outside air is at a low temperature.

For example, when the outside air temperature is low, around 20°C, new air sterilized at 100°C to 110°C is introduced by the heat exchanger 18 to adjust the temperature and humidity.

Furthermore, the conduit 24 with the damper 23 interposed is connected to the air conduit 3.
and the reflux pipe 2 to form an air bypass and change the circulation route so that when a large amount of air 1 is not required in the chamber 1, this bypass can be passed.

The structure of chamber 1 includes a moisture-proof wall 2 made of rubber or stainless steel on the inside.
8 is placed and surrounded by a water pipe 27.

Furthermore, the outside of the water pipe 27 is surrounded by an outer wall 26 made of a heat insulating material.

When the outside air temperature is high, water at a temperature slightly (for example, 2°C) lower than the temperature inside the room 1 is circulated through the water pipe 21.
When the temperature of the outside air is low, water having a temperature slightly higher than the temperature inside the room 1 is circulated so that the room 1 is not affected by the outside air.

Regarding the operation of the sterilization temperature and humidity control device of this invention.

The compressors 15, 15', . . . are operated to lower the water in the cold water tanks 10, 10', . . . to a predetermined temperature.

When the water drops to a predetermined temperature, temperature detectors c, c'
Compressor 15,1g... by command of -...
The switch ・opens and stops, and when the temperature rises, it closes and operates, performing NN-0FF control.

Chamber 1 is closed and fan F and pump P are operated.

First, 100°C steam is introduced into chamber 1 to sterilize the interior.

Next, dry air at 100°C is introduced to dry the entire chamber 1, and when the circulation continues, it is immediately cooled, and then
Sterilized air at around 0°C is introduced little by little.

Therefore, the air in the room 1 passes through the first cyclone 4, the spray Java coolers 6, 6-..., and the second cyclone 13, and is sterilized, purified, and the temperature and humidity are controlled to the optimum condition. Reflux.

When the temperature in room 1 falls to a predetermined temperature. Temperature detector A1t
A2 detects this state and stops fan F or controls the rotation speed of fan F.

In this case, operate the 7 an F as is and damper 23
It is also possible to open the damper 23 and close the damper 23 so that no air circulates in the chamber 1, or to close only the damper 23 so that the air is partially bypassed.

Therefore, the inside of the room 1 is always kept at the optimum temperature and relative humidity.

As a result, the interior of the room 1 can be maintained at a constant temperature and humidity, and can be kept clean and sterile at all times.
It is useful for controlling the atmosphere in a wide range of rooms such as buildings, as well as laboratories and vaccine production rooms.
By increasing the rotational speed of the pump P, the cooling air can be circulated quickly to cool the stored items in a short time.Also, the pump P can be stopped and the steam is spewed out from the steam pipe 14. Indoor air is purified during circulation, resulting in clean air, and odors generated indoors are deodorized by cold water, so no abnormal odor accumulates in the room.

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

Furthermore, since multiple cyclone-type spray Java coolers are arranged in sequence, the cyclone can be small and temperature and humidity control can be performed with precision.
