Detailed Description of the Invention This invention produces air at a predetermined low temperature and high humidity (substantially saturated humidity), and heats the air to a predetermined temperature by indirect heat exchange to obtain air at a desired temperature. The present invention relates to an air conditioner for producing and supplying the air. especially,
This invention is equipped with a cyclone type spray cooler, a cyclone type dedropper, and a heater using indirect heat exchange, and the cooling function and heat radiation function of the refrigerator are performed through two cold water tanks and two hot water tanks. Regarding the air conditioning equipment used in

Embodiments of the air conditioner of the present invention will be described in detail below with reference to the drawings.

In the drawing, arrow A indicates the flow of air, and arrow W indicates the flow of air.
indicates the flow of cold water, and arrow H indicates the flow of hot water. Air A in room 1 passes through ducts 2 and 3,
It is then fed by a fan 4 through a duct 5 to a cyclonic spray cooler 6 . The air A is fed tangentially to the inner periphery of the spray cooler 6 and is exposed to the cold water spray from the multiple spray ports 32 of the spray pipe 31 while swirling therein. By this action, the contaminated air containing dust and the like collected from the room 1 is purified, cooled, and humidified to approximately saturated humidity. The cooled, humidified, and purified air A rises up the pipe 7 and is sent from the pipe 8 to the cyclone type drip remover 9. The pipe 8 is attached tangentially to the upper inner circumference of the drip remover 9,
Therefore, the air A is sent in a swirling manner within the drip remover 9. At this point, water droplets contained in the air are completely removed. Water for drip removal is pipe 33, valve 3
4 and pipe 35, or collected into the cold water tank 26 (not shown). Next, the air from which the drops have been removed rises up the pipe 10 and is sent to the heater 12 through the duct 11. Here, the air is heated to a predetermined temperature by indirect heat exchange. Furthermore,
As the temperature of the air, which has been humidified to almost saturated humidity, is increased, the relative humidity decreases to a desired humidity level. For example, air having a temperature of 15° C. and a relative humidity of 95% is temperature-controlled and humidified by the heater 12 to air having a temperature of 22° C. and a relative humidity of 65%. The temperature and humidity controlled air is sent into the room 1 through the duct 13. Since the air is repeatedly circulated through the above steps, the air in the room 1 is always kept sterile and dust-free, and is also deodorized, and the temperature and humidity are controlled to the optimum condition. Duct 13 and Duct 2
are connected by a duct 14 via a valve 15, by opening the valve 15 the air can be bypassed. For example, assuming that the fan 4 always rotates at a constant speed, the amount of air blown into the room 1 can be controlled by bypassing it. Further, when there is no need to send air to the room 1 for cleaning the room 1, etc., the room 1 can be cleaned without closing the valve 15 and stopping the air conditioner. It is also possible to bypass the air when testing or sterilizing the air conditioner. Fresh air or oxygen can be taken in through the duct 16, valve 17. Additionally, air can be exhausted through the valve 18 and duct 19.

The cold water sprayed from the multiple spray ports 32 cleans and cools the air contaminated with dust, dirt, etc. from the room 1, and humidifies the air to a humid state, that is, almost saturated humidity, and then the pipe 20, the valve 21, and the pipe 29. The water is sent to the filter 22 through the. The filtered water is sent through a pipe 23, a pump 24, and a pipe 25 to a cold water tank 26 whose temperature is constantly controlled to a constant temperature. The cold water in the cold water tank 26 is sent to the spray pipe 31 through the pipes 27 and 30 by the action of the pump 28 . Spray pipe 3
1 surrounds the outer periphery of the pipe 7 and is arranged concentrically within the cyclone type spray cooler 6. The filter 22 can be washed by taking in water through the valve 93 and pipe 94 and discharging it through the pipe 91 and valve 92. cold water tank 26
Water can be taken in through pipe 54, valve 52 and pipe 53, and can be discharged through pipe 49, valve 50 and pipe 51. Further, the water in the cold water tank 26 is constantly stirred by a motor 46 and an agitator 46, and is kept at a uniform and constant low temperature.

A radiation pipe 77 is disposed within the heater 12 for indirect heat exchange with the air. The water in the hot water tank 91 is temperature-controlled to a predetermined temperature, and the hot water is pumped through the pipes 74 and 74 by the pump 75.
The water is sent to a heat dissipation pipe 77 through a pipe 76, where it exchanges heat with air, and then is collected into a hot water tank 91 through a pipe 78. Water in hot water tank 91 can be taken in through pipe 81, valve 80 and pipe 79 and discharged through pipe 83, valve 82 and pipe 84. Further, a stirrer 72 is disposed within the hot water tank 91, and the stirrer 72 is operated by the drive of the motor 71 to constantly stir the hot water and maintain it at a uniform temperature.

The temperature of the water in the cold water tank 26 and the water in the hot water tank 91 is indirectly controlled by the cooling function and heat radiation function of the refrigerator 36. The refrigerator 36 and the cooling pipe 47 are connected to each other via the pipes 37 and 38, and the cooling pipe 47 is arranged in the cold water tank 39. The water in the cold water tank 39 is transferred to the pipe 8
5, taken in through valve 86 and pipe 87 and pipe 88, valve 89 and pipe 90
can be discharged through. Further, the water in the cold water tank is constantly stirred by the action of a stirrer 40 and a motor 41, and is kept uniformly at a predetermined low temperature by exchanging heat with a cooling pipe 47. The water in the cold water tank 39 is sent from the pipe 44 to the cooling pipe 48 by the action of the pump 42, and after exchanging heat with the water in the cold water tank 26, is collected into the cold water tank 39 through the pipe 45. On the other hand, the heat dissipation pipe 58 is connected to the refrigerator 36 by pipes 56 and 57.
has been contacted. The heat radiation pipe 58 is arranged in a hot water tank 59 and is in a heat exchange relationship with the water therein. The water in the hot water tank 59 is taken in through pipe 67, pump 66 and pipe 65 and through pipe 60, valve 61 and pipe 6.
It can be discharged through 2. hot water tank 5
The water in 9 is constantly stirred by an agitator 64 and a motor 63, and pipes 67, 6 are used as needed.
By introducing cooling water through 5, hot water can be maintained at a predetermined appropriate temperature. Furthermore, the hot water in the hot water tank 59 is sent from the pipe 70 to the heat radiation pipe 69 by the action of the pump 92.
The heat radiation pipe 69 is disposed within the hot water tank 91 and is in a heat exchange relationship with the water within the hot water tank 91. The hot water passing through the heat radiation pipe 69 undergoes heat exchange with the water in the hot water tank 91 and is then collected into the hot water tank 59 through the pipe 68.

As an example when this air conditioner is operated, the following air temperature and humidity can be obtained. When the temperature of the water in the cold water tank 39 is 5°C, the temperature of the water in the cold water tank 26 is 12°C, and the air obtained by the cyclone spray cooler 6 is cooled to 15°C and reduced to 95%. humidified. On the other hand, when the water in the hot water tank 59 is at 35°C, the temperature of the water in the hot water tank 91 becomes 28°C, and is sent to the heater 12 to exchange heat with the air. As a result, the air is temperature-controlled and humidity-controlled to 22° C. and humidity 65%, and this air can be sent into the room 1.

As mentioned above, since the present invention is a cyclone type, the structure is simple and strong, and the operation is highly reliable, and the temperature is adjusted by providing two hot water tanks and two cold water tanks. , the temperature can be reliably adjusted, and furthermore, even in the event of a breakdown or power outage, such as a breakdown of the refrigerator 36, the hot water tank 91,
By increasing the capacity of the cold water tank 26, the system can be constructed so that it will not be affected immediately, and if it is repaired immediately and the system is operated again, the system will hardly be affected by the failure. In addition, since the heater uses indirect heat exchange, the air is not contaminated, and the air can be sent into the room 1 in a sterile, dust-free, and deodorized state after controlling the temperature and humidity. Furthermore, the cooling and heat dissipation functions of a single refrigerator are effectively utilized, resulting in extremely high efficiency.
