Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes a sterile temperature control device that maintains the temperature and humidity in a thermostatic chamber such as a hospital room at an optimal state, and circulates and maintains the atmosphere within the thermostatic chamber in a sterile state. This invention relates to an overflow structure in which pipes are arranged around a thermostatic chamber, the outside of the pipes are covered with an insulating chamber, and temperature-controlled water is flowed through the pipes to maintain the temperature of the thermostatic chamber at a predetermined constant temperature.

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 temperature room such as a hospital room, and the air in the constant temperature room 1 is sucked into the first cyclone 4 through an air conduit 3 connected to the circumference of the first cyclone 4 in a tangential direction. Daiichi Cyclone 4
A steam pipe 5 is connected to the steam pipe 5, and solid substances such as dust and garbage entrained from the greenhouse 1 are separated by the first cyclone 4 and discharged through the valve 22, thereby purifying the air. Further, if necessary, steam is blown in from the steam pipe 5 to sterilize the air from the thermostatic chamber 1. The air, which has been purified and sterilized by removing dust etc. by the cyclone 4, passes through a conduit 3' extending above the cyclone 4 to the fan F.
The water is sucked out from the cyclone 4 and blown into the cyclone type mist shower cooler 6. The cyclone-type fog shower cooler 6 communicates tangentially with the cyclone 4 and the air conduit 3', which is connected to the cyclone 4, and has a reflux pipe 7 extending upwardly fixed for transportation. A cold water pipe 8 is arranged around the reflux pipe 7. This cold water pipe 8 is provided with a large number of back doors 9a, 9b, 9c..., and these false mist ports are closed into the cyclone type false mist shower cooler 6, and the cold water pipe 8 is connected to the cold water tank 10. It is suitable for Yogi. 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 sent to the cold water pipe 8 by the pump P, and is turned into small droplets from the spray ports 9a, 9b, 9c, etc. The floor is foggy. The air that has entered the cyclone type mist shower cooler 6 is sent to the spray ports 9a, 9b, and g.
It comes in contact with water droplets from c..., where heat is exchanged quickly and efficiently, excess water due to cooling is condensed and deprived of water, insufficient water is humidified, and the water is saturated at a temperature roughly equivalent to the cold water temperature.
It is sent out from the reflux pipe 7. Since particulates such as odors and dust in the room are dissolved or suspended in the water from which heat has been taken, the water is passed through the conduit 11 into the furnace 12, filtered, and returned to the cold water tank 10 through the conduit 11. It will be done. Therefore, it is preferable that the furnace 12 is a normal furnace with an adsorbent material such as activated carbon, cinnabar algae, acid clay, or ion exchange resin layered on the furnace surface. As mentioned above, the air is saturated and humidified at low temperatures. The air exiting the cyclone mist shower cooler 6 is
It is sent through a return pipe 7 to a cyclone spray shower cooler 6'. The reflux pipe 7 closes tangentially around the cyclone mist shower cooler 6'. The cyclone mist shower cooler 6' has a similar structure to the spray shower cooler 6, and the same parts are designated by the same numbers, with a prime sign (') added to the numbers. Since the function of the cyclone-type mist shower cooler 6' is similar to that of the cyclone-type mist shower cooler 6, the explanation will be omitted here. Although only two cyclone type spray shower coolers are shown in the drawing, several more cyclone type spray shower coolers can be sequentially arranged as desired. Here, the air is sterilized and kept at a constant temperature and a saturated humidity of, for example, 18 qo, in a basic state that can be easily adjusted to any temperature and humidity.

The cooled and humidified air that exits the last cyclone-type mist shower cooler is still wet with some droplets, so it is completely dehydrated by the second cyclone 13.

Therefore, only the dehydrated air with optimal humidity returns to the thermostatic chamber 1 through the reflux pipe 2. One end of the steam pipe 14 is closed to the second cyclone 13, steam is blown in through the cyclone 21 as needed, the circulating air is heated, and the thermostatic chamber 1 and piping are sterilized through the reflux pipe 2. It can be carried out. The gas discharged from the cooling water cooling compressor 15, 15' is sent to the condenser 1.
6, 16' and an expansion valve (not shown) to cool the water in the cold water tanks 10, 10'. Temperature detector A,,A
2 and humidity detectors B, & are installed in the overflow room 1. Impurities from the cyclones 13, 21 are discharged through conduits 24, 25. Temperature detectors C and O are provided in the cooling water tanks 10 and 10'. Temperature detectors A, . . . are electrically coupled to the power of fan F (not shown), and temperature detectors C, C'
are electrically coupled to the compressors 15, 15'. Steam pipe 14
is connected to the third cyclone 21, and is the third cyclone.
The cyclone 21 is configured to remove water droplets from the fresh 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, which includes a filter 19 and a heat exchanger 18.
Fresh air can be fed into the second cyclone 13 through. The heat exchanger 18 is a heating device that can be heated intermittently 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 about 20 degrees Celsius, fresh air sterilized to 100 to 110 qo is introduced by the heat exchanger 18 to adjust the temperature and humidity. Furthermore, a conduit 24 with a damper 23 interposed therebetween is connected to the air conduit 3' and the reflux tube 2 to constitute an air bypass and change the circulation route. to be able to pass through.

The structure of the thermostatic chamber 1 is such that a heatproof wall 28 made of rubber or stainless steel is placed inside, and a pipe 27 surrounds the wall 28 . Further, the outside of the pipe 27 is surrounded by an outer wall 26 made of a heat insulating material. When the outside temperature is high, the pipe 27 displays the temperature inside the constant temperature room 1 (
For example, circulate water at a temperature slightly lower (for example, 20℃) than 20℃ (18℃), and when the outside temperature is low, the temperature is slightly higher than the temperature inside constant temperature room 1 (for example, 20:00). 220 water is circulated so that the thermostatic chamber 1 is not affected by the outside air. In this case, the temperature of the water flowing through the pipe 27 can be adjusted by the heat exchanger 29. Regarding the operation of the sterilization temperature and humidity control device of this invention, the compressors 15, 15'... are operated, and the cold water tanks 10, 10' are operated.
... lowers the water inside to a specified temperature.

When the water drops to a predetermined temperature, temperature detectors C, C'...
According to the commands, the switches of the compressors 15, 15', etc. are opened and stopped, and when the temperature rises, they are closed and operated, resulting in ON-OFF control. The constant temperature room 1 is closed, and the fan F and pump P are operated. First, 10,000 ml of steam is placed in a thermostatic chamber 1 to sterilize the interior of the thermostatic chamber. Next, 10
000 dry air is put in to dry the entire thermostatic chamber 1, and when the circulation continues, it is immediately cooled and continues to be 200
Inject sterile air of approximately 0. Therefore, the air in the constant temperature room 1 is transferred to the first cyclone 4, the fog shower cooler 6
, 6'..., through the second cyclone 13, it is sterilized, purified, temperature and humidity controlled to the optimum condition, and then returned to the greenhouse 1.
When the temperature inside constant temperature room 1 falls to a predetermined temperature, temperature detector A
,, detects this state and stops the fan F or controls the rotation speed of the fan F. In this case, the fan F may be operated as is, the damper 23 may be opened and the damper 23' may be closed to prevent air from circulating in the thermostatic chamber 1, or only the damper 23 may be closed to partially bypass the air. Therefore, the inside of the constant temperature room 1 is always kept at the optimum temperature and relative humidity. As a result, the temperature inside constant temperature room 1 is constant,
A constant humidity can be maintained and a clean and sterile condition can be maintained at all times.

The present invention is not limited to the management of constant temperature rooms used as hospital rooms, but can be used not only in operating rooms, laboratories, vaccine production rooms, etc., but also for controlling the atmosphere in a wide range of rooms such as buildings.
Furthermore, the rotational speeds of the fan F and pump P can be increased to circulate cooling air quickly and cool the stored items in a short time.
It is also possible to sterilize the temperature-controlled chamber 1 by stopping the pump P and blowing out steam from the steam pipe 14 and transporting it by circulating air.The air in the constant-temperature chamber 1 is purified during circulation, so it becomes clean air. Odors generated within the thermostatic chamber are deodorized by cold water, so no strange odors accumulate within the thermostatic chamber.

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. Since it uses a double cycle, it has many advantages such as less heat loss.
Furthermore, since multiple cyclone-type mist shower coolers are arranged one after the other, the cyclone can be small, and temperature and humidity control can be controlled with precision. In particular, this thermostatic chamber structure can maintain a constant temperature, so it requires very few temperature and humidity control devices, and only a small amount of air needs to be sent. Further, the inner heat-insulating wall 28 is not necessarily required.
