Description

TECHNICAL FIELD [0001] The present invention relates to an artificial intelligence high efficiency dehumidification system and a control method thereof,

The present invention relates to an industrial dehumidification system, and more particularly, to a system and method for dehumidification of an indoor space, Efficiency dehumidification system and method for controlling the same, which can minimize consumption of exhaust gas.

Air conditioners for air conditioning are well known. The air conditioner circulates the refrigerant between the indoor unit and the outdoor unit. The circulating refrigerant evaporates in the indoor unit, takes heat from the room air, and then moves to the outdoor unit. After the refrigerant in the gaseous state moved to the outdoor unit is compressed by the compressor, Condensation heat is released to the outside air.

In order to reduce the humidity in the room air using such an air conditioner, it will be required to separate the air and the moisture by lowering the room temperature to a temperature at which the water vapor contained in the room air condenses. However, since the condensation temperature is excessively lower than a temperature suitable for air conditioning, excessively cooled air is directly supplied to the inside of the room, which is likely to harm indoor comfort.

As described above, although the previous air conditioner is biased only to the temperature control of the indoor air, in recent years, there has been a need for effective temperature control in addition to the temperature control of the indoor space. For this reason, a humidity control scheme through cooling and reheating has been proposed as an alternative. In the case of the domestic air conditioner, a technique of introducing a part of the condensed heat into the indoor unit for reheating has been developed, but in the industrial duct air conditioner, a separate heat source for reheating is inevitably required. In addition, it is difficult to apply conventional air conditioners to many workplaces in factories where it is required to maintain a relative humidity as low as 30% or less, and more cooling and dehumidifying devices are required. However, in this case, the economical efficiency is greatly reduced due to excessive energy consumption.

[

The artificial intelligence high efficiency dehumidifying system according to the present embodiment is characterized in that the electric power consumption of each of the electric heater 4, the first fan 5, and the second fan 6, which are highly correlated with humidity control, (P) for electronically controlling the electric power of the electric heater (1), the first fan (5) and the second fan (6) electronically, and an electric power meter And a controller for controlling the digital power controller I based on the information provided by the integrated watt-hour meter I to optimize the humidity of the indoor space T while minimizing power consumption of the entire system 7). The controller 7 includes an artificial intelligence program 72.

Meanwhile, the artificial intelligent high efficiency dehumidification system according to the present embodiment is based on the humidity information of the indoor space, and when the humidity control is unnecessary, the outdoor air is directly introduced into the indoor space T without passing through the dehumidification rotor 1, And a bypass line BP bypassing the dehumidification rotor 1 and directly connecting the outside air introduction line L1 and the processing air supply line L2.

 A filter 11, a first damper 12, a pre-cooling means 2 and an eliminator 13 are provided on the outside air introduction line L1 from the outside air inlet to the first connection point of the bypass line BP Respectively. An aftercooling means 3 is provided on the process air supply line L2 between the outlet of the dehumidifying rotor 1 and the second connection point of the bypass line BP.

The controller 7 dehumidifies or cool / warms the outside air according to the external temperature and humidity conditions and the temperature and humidity of the indoor space T, and supplies the processed dehumidified air to the indoor space T Controls each element in the system. That is, the controller 7 selectively performs the heating operation using the electric heater 4 and the blowing operation using the first fan 5 and the second fan 6 according to the external temperature and humidity conditions, And supplies the processing space to the indoor space to maintain the indoor space at an appropriate temperature and humidity.

As described briefly above, the artificial intelligent high-efficiency dehumidification system according to an embodiment of the present invention integrates the elements consuming a large amount of electric power among elements having a high correlation with humidity control, Is also configured to maintain the humidity of the indoor space.

In the dehumidifying system according to the present embodiment, the elements that consume a lot of power while greatly affecting the dehumidification are the electric heater 4, the first fan 5, and the second fan 6. It should be noted, however, that the above elements may include the compressor 22 of the pre-cooling means 2 and / or the compressor 32 of the after-cooling means 3.

In this embodiment, the AI watt hour meter I, the digital power controller P and the AI program 72 provided in the controller 7 are provided for effectively managing the strategic consumption of these elements.

The control logic of the present system largely includes a process for confirming the necessity of humidity adjustment shown in Fig. 2 and a humidity adjustment process shown in Fig.

The humidity control necessity confirmation process is performed by the humidity control confirmation process section of the controller. As shown in Fig. 2, the humidity setting control process is performed by setting the data setting step s11, the current humidity verification and recording step s12, (S13), a management time range satisfying determination step (s14), a humidity management range outward count counting step (s15), and a departure times comparison determination step (s16).

The data setting step s11 is performed by the user when the operation of the system is started. In the data setting step s11, the reference humidity H s of the indoor space, the upper and lower limits L min and L max of the indoor space humidity control range, the humidity check interval P t , the management time range R t , The maximum number of coincidence counts (N e ) is input and set by the user.

Next, in the current humidity confirmation and recording step s12, the current humidity of the indoor space is confirmed and recorded according to the humidity check interval. At this time, the information of the current humidity that is confirmed and recorded includes time information.

It is that the humidity control-range state determining step (s13) the into the current humidity whether or leaving with respect to the comparison with a current humidity in the upper and lower (L min, L max) determined by the upper and lower limit humidity control range is determined . If the current humidity is within the humidity management range, the process goes back to the present humidity determination and recording step s12. If the current humidity is outside the humidity management range, the management time range satisfying step s14 is determined.

For the management time range satisfying determination step (s14), the past humidity data for a predetermined management time is fetched based on the time at which the current humidity is measured. If the past data is less than the management time range, it is determined as the setup time, and the process returns to before the current humidity determination and recording step s12. If the management time range is satisfied, the process proceeds to the humidity management range outward frequency count step s15.

In the departure frequency comparison determination step s16, the number of departure times counted in the step s14 is compared with the management chance number maximum value Ne. If the counted number of departures is less than the management chance count, the process returns to the current humidity determination and recording step s12. If the counted number of departures is equal to or greater than the management count, the process proceeds to the humidity control process shown in FIG.

3 is a control chart related to the process for confirming the necessity of the humidity control described above. The time range of interest is 5 seconds, there are 6 measurement points in 5 seconds, and the interest frequency is 6 times. Up to each alphabet point (A to T) indicates the humidity periodically checked. The current point is point T. When the system first started and measured the humidity, it was equal to the reference humidity, which is point A on the graph. We measured the next cycle and were out of management cap (point B). At this time, the system for monitoring the humidity judges that there is no necessity of the humidity control since the history data is only the data of the interval of 2 seconds to retrieve the past humidity history data. The humidity from the next point C to the point G is within the upper and lower limits of the management, so there is no need to adjust the humidity. Since we have exceeded the upper limit of management at point H, historical data of the past is retrieved to determine if humidity control is needed (here, the humidity of five points in the near past). Here, points C to D except for point H are within the upper and lower limits of management, so they are regarded as random fluctuations that do not need to be controlled, and humidity control is not performed. The same situation continues from point I to point S. However, at the last point T, since the humidity of six points (the current point and the past five points) is out of the upper limit of six times in the range of interest, it is judged that the humidity is higher than the reference humidity and the humidity control process is started. It is important to note that this is beyond the scope of management. If all six points exceed the upper management limit or the lower management limit, the humidity control process is started. However, if the management upper limit and the management lower limit are alternately switched, the humidity control process is not started.

The humidity control process is performed by the humidity control process section of the controller. 4, the humidity control in the process and step (s21) of calculating the current average humidity, the present temperature of the step (s22), and an electric heater for calculating the difference (ΔH) of the current average humidity and the reference humidity (T H , p), the current input power (W H, p), monthly cumulative amount of power (CW H, p), the current speed (V F1, p of step (s23-1) and the first fan to determine up to now), A step S23-2 of confirming the current power input amount W F1 p and the monthly cumulative power amount CW F1 p at the present time and the current speed V F2 p of the second fan, W F2, p ), and a step (s23-2) of confirming the monthly accumulated power amount (CW F2, p ) up to the present.

The current average humidity of step s21 is calculated as follows.

The compressor of the pre-cooling means and / or the compressor of the after-cooling means may be included in consideration. In this case, a step of checking the current motor speed, the power input amount and the monthly accumulated power amount of the compressor will be added.

After step s21 and step s22 and steps s23-1, s23-2 and s23-3 are performed in step s24, among the elements including the electric heater, the first fan and the second fan, The amount of power is determined and the process goes to step s22.

At this time, the objective formula is as follows.

Where A W is a constant in the cost per watt table, D a is the cost incurred due to humidity control failure, and D b is the cost incurred due to excessive power consumption.
