Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and specifically relates to a constant temperature and humidity unit and a control method thereof. Background Art

[0002] Traditional electric heating humidification units generate water vapor by boiling water through electric heating, and introduce it into the air outlet through a steam pipe and diffuse it into the air to humidify the surrounding air. However, restricted by the environment, the starting temperature cannot be controlled before the unit starts to operate. The humidification water tank may cause the initial temperature of the electric heating to drop due to the low ambient temperature. At this time, the temperature of the unit at the initial operation is too low. When the unit starts PID regulation, the water temperature of the humidification water tank drops so much that it is not enough to directly generate steam by heating. In the short term, no water vapor can be obtained in the air, and the humidity cannot reach the upper guide requirement. But in this state, the PID is still in the regulation operation state, that is, when the low-temperature start of the humidification water tank rises to the temperature at which water vapor can be generated, the PID control end has output parameters exceeding the conventional estimated values. The PID parameters of the humidification unit are adjusted to meet the standard humidification requirements under low-temperature start, and the overall humidification effect is poor. Especially when it comes to the synchronous operation of multiple units in a large space, due to the temperature difference between different areas, it is impossible to synchronously and accurately output after meeting the water vapor generation requirements within the same time interval.

The over-threshold shutdown module is used to analyze whether the output temperature within the current start-up duration meets the preset value, and upload it to the central control end for correcting the debugging parameter value of subsequent compensation.

[0014] Preferably, the steps for the collaborative calculation value sensing module to calculate the compensation amount according to the ambient temperature are as follows:

[0015] Step S1: Enable the parameter interference processing module to read the real-time data of the temperature sensing points set inside each humidification unit of the collaborative computing value sensing module, and set the real-time data obtained from the temperature sensing points in each single-group humidification unit end as:

Then, the feedforward compensation preheating end is allocated to compensate for the amount required for the low-temperature atomization startup of the humidification unit, and the time interval for each humidification unit to reach the compensation amount is uniformly set. After that, the feedforward compensation preheating end reads the compensation amount required for each humidification unit allocated by the low-temperature collaborative startup processing end and performs preheating operations on the inside of each humidification unit according to the compensation debugging parameters set by the low-temperature collaborative startup processing end. Until the internal environmental temperature of the humidification unit reaches the set compensation amount within the compensation time interval set by the low-temperature collaborative startup processing end, PID adjustment is started, so that the atomized liquid preheated by each humidification unit can be quickly heated to the atomization demand temperature without being affected by low-temperature response delay, and is uniformly output within the compensation time interval set by the compensation value, thereby ensuring that when multiple humidification units operate in the same area, the output of water vapor can be completed synchronously.

[0040] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0041] As Figure 1 - Figure 2 shown, a constant temperature and humidity unit of the present invention includes a plurality of humidification unit ends 5, and further includes:

[0042] A low-temperature collaborative startup processing end 1, which is used to set compensation debugging parameters that can reduce the initial thermal inertia inside the humidification unit end 5 according to the environmental temperature.

[0043] The PID delay terminal 2 is used to delay the start-up time of the PID regulation in the humidification unit end 5 when the humidification unit end 5 is in the compensation debugging stage.

[0044] In an alternative embodiment of the present embodiment, the PID delay terminal 2 is arranged inside the humidification unit end 5. The PID delay terminal 2 selects a delay device. When the temperature of the humidification water tank inside the humidification unit end 5 does not reach the temperature required for low-temperature start-up, the start-up time of the PID regulation in the humidification unit end 5 is delayed by the PID delay terminal 2.

[0045] The feed-forward compensation preheating terminal 3 is used to receive the compensation debugging parameters output by the PID delay terminal 2 and perform feed-forward compensation on the temperature difference between the internal and external environments of the humidification unit end 5.

[0046] The operation monitoring terminal 4 is used to monitor the PID regulation dynamics of the humidification unit end 5 in real time after the feed-forward compensation process is completed.

[0047] In the present embodiment, the low-temperature cooperative start-up processing terminal 1 includes a cooperative calculation value sensing module 11, an enabling parameter interference processing module 12, a timely distribution module 13, a distribution signal sending module 14, and a delay adjustment measurement module 15. The cooperative calculation value sensing module 11 is used to obtain the ambient temperature of each humidification unit end 5. The enabling parameter interference processing module 12 calculates and obtains the compensation amount for low-temperature atomization start-up according to the ambient temperature. The timely distribution module 13 is used to uniformly set the time interval for each humidification unit end 5 to perform low-temperature atomization start-up compensation, and distribute the compensation amount required for each humidification unit end 5 during low-temperature atomization start-up according to the compensation time interval. The distribution signal sending module 14 is used to send the corresponding compensation amount of each humidification unit end 5 to the feed-forward compensation preheating terminal 3. The delay adjustment measurement module 15 is used to measure whether the PID regulation continues to be delayed after the feed-forward compensation preheating terminal 3 completes the compensation according to the compensation amount. Among them, a number of temperature sensing points are arranged inside each humidification unit end 5 in the cooperative calculation value sensing module 11.

[0048] In a preferred embodiment of the present embodiment, at least three temperature sensing points (NTC temperature sensors) are arranged inside each humidification unit end 5 in the cooperative calculation value sensing module 11. The three temperature sensing points are respectively arranged inside the atomization water tank in the humidification unit end 5 and at the location where the humidification unit end 5 is located, so as to accurately obtain the temperature of the atomization water tank in the humidification unit end 5 before start-up.

[0049] In an alternative implementation of this embodiment, the feedforward compensation preheating end 3 includes a water tank heater, a signal reading unit, and a control and processing single board. The water tank heater is installed in the humidification unit end 5. The signal reading unit is signal-connected to the control and processing single board, and the control and processing single board is signal-connected to the water tank heater. Both the distribution signal sending module 14 and the delay adjustment measurement module 15 are signal-connected to the signal reading unit. Among them, the water tank heater can be a contact heat exchanger, and its heat forming surface is sleeved outside the atomization water tank for externally wrapping and electrically heating the atomization water tank in the humidification unit end 5, so that the temperature inside the atomization water tank rises more evenly.

[0050] In an alternative implementation of this embodiment, the operation monitoring end 4 includes a start timing unit 41, an output temperature detection unit 42, and an over-threshold shutdown module 43. The start timing unit 41, the output temperature detection unit 42, and the over-threshold shutdown module 43 are all signal-connected to the humidification unit end 5. The start timing unit 41 is used to record the activation duration after the atomization of the humidification unit end 5 starts. The output temperature detection unit 42 is used to measure the real-time temperature when the atomization output of the humidification unit end 5 occurs. The over-threshold shutdown module 43 is used to analyze whether the output temperature within the current activation duration meets the preset value and upload it to the central control end for correcting the debugging parameter value of subsequent compensation.

[0051] In this embodiment, before the operation, first, the over-threshold shutdown module 43 preset the maximum adjustable temperature range of the atomization water tank in the humidification unit end 5. When the atomization water tank in the humidification unit end 5 is heated by the feedforward compensation preheating end 3, the start timing unit 41 starts the heating start timing. After the atomization water tank in the humidification unit end 5 is heated to a fixed temperature, the start timing unit 41 records the total duration from the current heating start to the heating completion for later determination of whether the heating power of the current feedforward compensation preheating end 3 can meet the heating requirements within the preset heating duration. And after the heating is completed, when the humidification unit end 5 starts PID regulation for the heating output of the atomizing liquid, the output temperature detection unit 42 is used to detect whether the temperature of the atomizing liquid output from the atomization water tank to the outside is lower than the temperature inside the atomization water tank (that is, the temperature of the atomizing liquid output is not less than the temperature inside the atomization water tank ±3°C). That is, when the output temperature is close to the temperature inside the atomization water tank, the current low-temperature start compensation is successful. When it exceeds the set range, the compensation fails, and the PID delay end 2 continues to delay the PID regulation of the humidification unit end 5, and the low-temperature cooperative start processing end 1 compensates and distributes the heating amount again.

[0052] In an alternative implementation of this embodiment, the steps for the cooperative calculation value sensing module 11 to calculate the compensation amount according to the ambient temperature are as follows:

[0053] Step S1: Enable the parameter interference processing module 12 to read the real-time data of the temperature sensing points set inside each humidification unit 5 of the collaborative computing value sensing module 11, and set the real-time data obtained from the temperature sensing points in each single-group humidification unit 5 as follows:

[0054] ;

[0055] In the formula: refers to the set of real-time data obtained from the temperature sensing points in any single-group humidification unit 5, Z1 is the real-time sensing data of the first temperature sensing point, Z2 is the real-time sensing data of the second temperature sensing point, and Zn is the real-time sensing data of the nth temperature sensing point;

[0056] Step S2: Ascend the above-obtained measurement data to obtain an ordered sequence: = ;

[0057] In the formula, ≤ ≤ , where refers to the first minimum value of the real-time sensing data of the temperature sensing point, refers to the second minimum value of the real-time sensing data of the temperature sensing point, refers to the nth minimum value of the real-time sensing data of the temperature sensing point;

[0058] Step S3: Calculate the median option according to the number of temperature sensing points inside each humidification unit 5. When the number of temperature sensing points is odd, substitute it into the following formula:

[0059] ;

[0060] When the number of temperature sensing points is even, substitute it into the following formula:

[0061] ;

[0062] In the formula, is the number of temperature sensing points;

[0063] Step S4: Select the median value in the ordered sequence according to the median option , and use the median value as the temperature measurement parameter value before compensation, and set the corresponding temperature measurement parameter value as , , ;

[0064] Step S5: Compare the mutual difference between the conventional PID start temperature set at the humidification unit end 5 and the temperature measurement parameter value of the current corresponding group, and send the difference as a compensation debugging parameter to the feed-forward compensation preheating end 3.

[0065] In an alternative embodiment of this example, the calculation steps for the collaborative calculation value sensing module 11 to determine whether the humidification unit end 5 continues to delay PID start are as follows:

[0066] Step S1: Obtain the start temperature of the humidification unit end 5 at each distribution position in the normal temperature cycle, and set the conventional start temperature as , , , ;

[0067] Step S2: Obtain the static weights , , , according to the influence of the temperature at the installation position of each humidification unit end 5 on low-temperature start.

[0068] Step S3: Substitute the conventional temperature value into the static weight through the following formula to obtain the stable measurement value: ;

[0069] Step S4: Substitute the temperature measurement parameter value into the static weight through the following formula to obtain the stable measurement value: ;

[0070] Step S5: Compare and for the numerical error value. The delay adjustment determination module 15 determines whether the humidification unit end 5 continues to delay PID start, that is, when the delay adjustment determination module 15 determines that is lower than by more than 2°C, the distribution signal sending module 14 sends a delay signal to the PID delay end 2, and controls the humidification unit end 5 to continue to delay PID adjustment start through the PID delay end 2, while the feed-forward compensation preheating end 3 continues to heat; when the delay adjustment determination module 15 determines that is higher than by 1 - 3°C, the distribution signal sending module 14 sends a signal to stop continuous heating to the feed-forward compensation preheating end 3, so that the feed-forward compensation preheating end 3 maintains the current temperature heating power, and the humidification unit end 5 sends a PID debugging start signal; and when the delay adjustment determination module 15 determines that is higher than ​After exceeding 3.1°C, the distribution signal sending module 14 directly sends a stop heating signal to the feed-forward compensation preheating end 3, and controls the humidifying unit end 5 to continue to delay the PID start through the PID delay end 2 until the median temperature of the atomizing water tank in the humidifying unit end 5 measured by the collaborative calculation value sensing module 11 drops to When it is in the range, the PID regulation unit in the humidifying unit end 5 starts power regulation and atomizes and outputs the atomizing liquid in the atomizing water tank.

[0071] In an alternative implementation manner of this embodiment, the control method of the constant temperature and humidity unit is as follows: First, the collaborative calculation value sensing module 11 in the low-temperature collaborative start processing end 1 reads the internal environment temperature of each humidifying unit end 5, and the enabled parameter interference processing module 12 sets corresponding compensation debugging parameters according to the difference between the internal environment temperature of each humidifying unit end 5 and the atomizing required temperature. Then, the timely distribution module 13 distributes the compensation amount required for the low-temperature atomizing start of the humidifying unit end 5 by the feed-forward compensation preheating end 3, and uniformly sets the time interval when each humidifying unit end 5 reaches the compensation amount; after the feed-forward compensation preheating end 3 receives the compensation amount required for each humidifying unit end 5 distributed by the timely distribution module 13 through the distribution signal sending module 14, it performs the preheating operation on the inside of each humidifying unit end 5 according to the compensation debugging parameters set by the enabled parameter interference processing module 12. During the preheating operation stage, the start time of the PID regulation in each humidifying unit end 5 is appropriately extended; until each humidifying unit end 5 receives the preheating compensation from the feed-forward compensation preheating end 3 and its internal environment temperature reaches the set compensation amount within the compensation time interval set by the low-temperature collaborative start processing end 1, the internal environment temperature of the humidifying unit end 5 reaches the normal atomizing temperature value. At this time, the PID regulation in the humidifying unit end 5 is started, so that the atomizing liquid preheated in each humidifying unit end 5 is quickly heated to the atomizing required temperature in the state of not being affected by the low-temperature response delay, and is uniformly output within the compensation time interval set by the compensation value; finally, when the humidifying unit end 5 starts normal atomizing output, the real-time temperature during the atomizing output of the humidifying unit end 5 is measured by the operation monitoring end 4, and it is analyzed whether the output temperature conforms to the preset value, so as to confirm whether the current low-temperature start compensation is successful.

Step S3: After each humidification unit terminal (5) receives the preheating compensation from the feedforward compensation preheating terminal (3) and its internal ambient temperature reaches the set compensation amount within the compensation duration interval set by the low-temperature collaborative start processing terminal (1), the internal ambient temperature of the humidification unit terminal (5) reaches the normal atomization temperature value. At this time, PID regulation is started, so that the atomized liquid preheated in each humidification unit terminal (5) can be quickly heated to the atomization required temperature without being affected by the low-temperature response delay, and uniformly output within the compensation duration interval set by the compensation value. Step S4: When the humidification unit end (5) starts normal atomization output, the operation monitoring end (4) measures the real-time temperature during the atomization output of the humidification unit end (5), analyzes whether the output temperature meets the preset value, and further confirms whether the current low-temperature start-up compensation is successful.
