1 and 2, the constant temperature and humidity chamber of the high-pressure spray method according to the present invention is a constant temperature and humidity cabinet adopting a new humidification method of indirect pressurization using air pressure, and a setting input unit 100 for setting a desired temperature and humidity; , Through a detector 200 for measuring room temperature and humidity, a constant temperature unit 300 for cooling and heating the room to be maintained at a desired temperature input through the setting input unit 100, and the setting input unit 100. The humidity and humidity unit 400 that maintains the indoor humidity at the desired desired humidity and the temperature and humidity input from the detection unit 200 and the desired temperature and humidity set through the setting input unit 100 are compared, and the result Accordingly, the control unit 500 controls the on / off of the cooling, heating, and the humidity unit 400 of the constant temperature unit 300.

The detector 200 detects a current temperature and humidity and outputs an output signal according to the controller 500. The setting input unit 100 includes a display window displaying temperature and humidity, several lamps and buttons as a control panel, and inputs a control signal such as checking or changing current or setting temperature and humidity.

Meanwhile, the constant temperature unit 300 may include a cooling unit 310 and a blowing fan 320 for cooling and heating the room to maintain the temperature input from the detection unit 200 at a desired temperature set by the setting input unit 100. Consists of a heater 330, the cooling unit 310 forms a cooling cycle consisting of the evaporator → pump → compressor → valve → evaporator and supplies the cool air through the evaporator located in the interior space side, the supplied cold air is the evaporator It is forcedly blown into the room by the blowing fan 320 located rear of the.

The heater 330 heats the air to maintain the set temperature when the current temperature of the room is lower than the set temperature. The heater 330 is positioned between the cooling unit 310 and the blower fan 320 by a thyristor. Driven through proportional calculus (PID) control.

The proportional calculus (PID) control method is a continuous control method including both proportional motion, integral motion, and derivative motion. The proportional motion that compares the present temperature with the set temperature and supplies power to the heating element in proportion to the magnitude of the deviation signal. And, since the integral operation to remove the control error and increase the control accuracy, and the derivative operation to increase the response speed of the device is performed, the optimum control can be achieved.

Therefore, in the embodiment of the present invention, the thermo-hygrostat of the high pressure spray method controls the amount of power supplied to the heater in a size proportional to the difference between the set temperature and the room temperature so as to always approach the set temperature, thereby precisely controlling the temperature. In addition, it can not only do heat dissipation when the set temperature is reduced, so that the consumption of heat can be reduced to obtain a power saving effect, and the internal structure can be easily configured.

Meanwhile, when the humidity input from the detection unit 200 is lower than the desired humidity set through the setting input unit 100, the humidity unit 400 mixes the time and high pressure air supplied from the outside to the indoor space through the nozzle. By spraying at high speed, it consists of the water supply part 410 to which water is supplied, the pressure supply part 420 to which high-pressure air is supplied, and the spray pipe 430 in which the nozzle 431 is formed.

The water supply water supply unit 410 is mounted to the storage tank 412 for storing the time water flowing through the water supply pipe 411 and the water supply pipe 413 connected to the outlet of the storage tank 412 and the control unit 500 It is composed of a water supply opening and closing portion 414 for opening and closing the water supply to the spray pipe 430 under the control of the), and supplies the water to the spray pipe 430 according to the opening and closing of the water supply opening and closing portion 414.

At this time, the storage tank 412 is provided with an electronic valve (not shown) for measuring the water level of the time stored in the tank, the output of the electromagnetic valve in the water supply pipe 411 through which the water flows into the storage tank 412. The water level adjusting unit 415 is further provided to adjust the supply amount of the storage tank according to the signal.

Accordingly, it is possible to measure the water level of the stored time in the storage tank through the electronic valve, and to control the supply amount of the time water introduced into the storage tank by adjusting the solenoid valve which is the level control unit. At this time, it is preferable to install a check valve in the water supply pipe in order to prevent the reverse flow from the storage tank to the solenoid valve which is a water level control unit.

And the water supply pipe 413 between the water supply opening and closing portion 414 and the spray pipe 430 is further provided with a filter unit 416, by removing the foreign matter contained in the time water supplied to the spray pipe 430 When spraying, the nozzle can be prevented from clogging.

In addition, according to an additional aspect of the present invention, the water supply pipe 413 is further equipped with a sterilizer supply unit 417 for constantly supplying a sterilizer for sterilizing the time water supplied to the spray pipe 430 according to the supply amount of time water have. Accordingly, the sterilizing agent is sterilized by the sterilizing agent supplied from the sterilizing agent supply unit 417 and humidified by using the sterilized treating water, thereby providing a more comfortable and clean environment.

The pressure supply unit 420 is mounted on the pressure tank 422 in which the high pressure air is stored by the compressor 421 and the pressure supply pipe 423 connected to the outlet of the pressure tank 422. In accordance with the control of the) is composed of a pressure switch 424 for opening and closing the pressure supply to the spray pipe 430.

Accordingly, the pressure supply unit 420 opens and closes the pressure switch 424 under the control of the control unit 500, which will be described later. At this time, the pressure switch 424 is simultaneously turned on / off with the water supply switch 414. It is preferable to provide a check valve between the water supply and pressure opening and the spray tube in order to supply the time and high pressure air to the spray tube at the same time, in order to prevent the reverse flow of the supplied time and high pressure air.

On the other hand, the spray tube 430 is a high-temperature spraying of the time water supplied through the plurality of nozzles by mixing the time water and the high pressure air supplied from the water supply water supply unit 410 and the pressure supply unit 420, the constant temperature At least one is provided in front of the part (300). And preferably, the spray pipe 430 is additionally equipped with a pressure control unit 432 for adjusting the internal pressure on the side in which the time and high pressure air is mixed.

Therefore, the time water flowing from the feed water supply pipe and the high pressure air supplied through the pressure supply pipe are mixed and flowed along the spray pipe at high pressure, and are sprayed at high speed with the fine particles while passing through the nozzle located in front of the constant temperature part, for example, in front of the evaporator. .

This nozzle spraying method is greatly influenced by the pressure of the water flowing along the spray tube, that is, the internal pressure of the spray tube. When the internal pressure is small, spraying itself is impossible, and in the large case, the spray tube may be damaged by the internal pressure. This makes it impossible to continue driving.

Accordingly, the present invention maintains a constant pressure inside the spray tube through the pressure adjusting unit as described above, which prevents the spray tube from being damaged by the internal pressure, maintains the spray state well, and maintains continuous and stable operation. Will be performed.

On the other hand, when humidifying through the nozzle spray method as described above, the hunting phenomenon of dropping the surrounding heat is generated while the low temperature water flowing into the spray tube 430 is sprayed into the fine particles. The present invention further includes a thermostat (not shown) for supplying heat to the stored water stored in the tank to one side of the storage tank 412 in order to prevent the hunting phenomenon as described above. .

Therefore, in the embodiment of the present invention by using a thermostat (not shown) by heating the time stored in the storage tank 412 to maintain 25 ℃ to 30 ℃, by supplying it to the spray pipe 430, spraying, The width of the temperature change caused by the hunting phenomenon can be minimized.

Meanwhile, as shown in FIG. 2, the controller 500 compares the current temperature and humidity input from the detector 200 with the desired temperature and humidity set through the setting input unit 100, and accordingly, the constant temperature. The on / off control of the cooling, heating, and humidity control unit 400 of the unit 300 includes a memory unit 510, a calculation unit 520, a humidity control unit 530, and a temperature control unit 540.

The memory unit 510 stores the desired temperature and humidity set through the setting input unit 100. The calculation unit 520 calculates a difference between the current temperature and humidity input from the detection unit 200 and the desired temperature and humidity, and outputs the result to each humidity () and the temperature control unit 540.

Accordingly, the humidity control unit 530 simultaneously controls the on / off of the water supply opening / closing unit 414 and the pressure opening and closing unit 424 of the humidity controller 400 according to the humidity difference inputted from the calculating unit. When the humidity is lower than the two opening and closing the opening at the same time, when the current humidity is higher than the desired humidity or when the set proximity humidity is reached, the two opening and closing at the same time.

Meanwhile, the temperature controller 540 controls the cooling unit 310, the blowing fan 320, and the heater 330 according to the calculation result of the temperature input from the calculating unit 520, and the cooling unit 310. And the blowing fan 320 is always constantly operated during temperature control and as described above the heater 330 is heated through the PID control by the thyristors to control the cooling, heating of the constant temperature unit 300.

That is, PID operation of the output signal according to the operation result input from the operation unit 520 outputs a control signal of 4 to 20 kHz to a thyristor serving as a heater driving unit. Accordingly, the thyristor controls the amount of heat generated by the heater 330 by the amount of power according to the control signal input from the temperature controller 540.

According to the operation as described above, the thermo-hygrostat according to the present invention outputs the current temperature and humidity input through the detection unit through the display unit, and compares the setting value stored in the memory unit and controls the humidity and temperature according to the result, Humidity can not only facilitate the humidification by indirect pressurization using air pressure but also a large amount of humidification by adjusting the number of nozzles. And the temperature can be precisely maintained at the set temperature by the PID control by the thyristor.

As described in detail above, the constant temperature and humidity controller of the high-pressure spraying method according to the present invention can indirectly pressurize the change of humidity in the indoor space by indirect pressurization using air pressure, and in particular, by controlling the spray amount according to the number of nozzles, the indoor space It can be installed in this large workplace to easily control the humidity of the indoor space.

In addition, by controlling the heater using the proportional calculus method by the thyristor, not only can the temperature be precisely controlled, but also the heat dissipation is not achieved when the set temperature is reached, so that the heat consumption can be reduced and the power saving effect can be obtained. There is an advantage to this.

Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the present invention from this description. Therefore, the scope of the present invention should be interpreted by the utility model registration claims described to include many such variations.
