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] The traditional electric heating humidification unit makes water boil to generate water vapor through electric heating, and the water vapor is introduced into the air outlet through a steam pipe and diffused into the air to humidify the surrounding air. However, affected 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 environmental 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 and 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 temperature of the humidification water tank rises from low temperature startup to the temperature at which water vapor can be generated, the PID control end has output parameters exceeding the conventional estimated values. The PID parameter adjustment of the humidification unit reaches the standard humidification requirement under low temperature startup, and the overall humidification effect is poor. Especially when it is applied to the synchronous operation of multiple units in a large space, due to the temperature difference between each interval, it is impossible to synchronously and accurately output after meeting the water vapor generation requirements in the same time interval.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] 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.

[0017] As Figure 1 - Figure 2 shown, a constant temperature and humidity unit of the present invention includes a plurality of humidification units 5, and further includes: A low-temperature collaborative start-up processing end 1, which is used to set compensation debugging parameters that can reduce the initial thermal inertia inside the humidification unit 5 according to the ambient temperature.

[0018] A PID delay end 2, which is used to delay the start time of PID regulation in the humidification unit 5 when the humidification unit 5 is in the compensation debugging stage.

[0019] In an alternative implementation of this embodiment, the PID delay terminal 2 is disposed inside the humidification unit terminal 5. The PID delay terminal 2 selects a delay device. When the temperature of the humidification water tank inside the humidification unit terminal 5 does not reach the temperature required for low-temperature startup, the PID delay terminal 2 delays the startup time of the PID regulation in the humidification unit terminal 5.

[0020] The feedforward compensation preheating terminal 3 is configured to receive the compensation debugging parameters output by the PID delay terminal 2 and perform feedforward compensation on the temperature difference between the internal and external environments of the humidification unit terminal 5.

[0021] The operation monitoring terminal 4 is configured to perform real-time monitoring on the PID regulation dynamics of the humidification unit terminal 5 after the feedforward compensation process is completely executed.

[0022] In this embodiment, the low-temperature cooperative startup processing terminal 1 includes a cooperative calculation value sensing module 11, an enabling parameter interference processing module 12, a timely allocation module 13, an allocation signal sending module 14, and a delay adjustment measurement module 15. The cooperative calculation value sensing module 11 is configured to obtain the ambient temperature of each humidification unit terminal 5. The enabling parameter interference processing module 12 calculates the compensation amount for low-temperature atomization startup based on the ambient temperature. The timely allocation module 13 is configured to uniformly set the duration interval for each humidification unit terminal 5 to perform low-temperature atomization startup compensation and allocate the compensation amount required for each humidification unit terminal 5 during low-temperature atomization startup according to the compensation duration interval. The allocation signal sending module 14 is configured to send the compensation amount corresponding to each humidification unit terminal 5 to the feedforward compensation preheating terminal 3. The delay adjustment measurement module 15 is configured to measure whether the PID regulation continues to delay after the feedforward compensation preheating terminal 3 completes the compensation according to the compensation amount. Among them, a plurality of temperature sensing points are provided inside each humidification unit terminal 5 in the cooperative calculation value sensing module 11.

[0023] In a preferred mode of this embodiment, at least three temperature sensing points (NTC temperature sensors) are provided inside each humidification unit terminal 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 terminal 5 and at the location where the humidification unit terminal 5 is located, for accurately obtaining the temperature of the atomization water tank in the humidification unit terminal 5 before startup.

[0024] In an alternative embodiment 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 and 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 formation 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.

[0025] In an alternative embodiment 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 the subsequent compensation.

[0026] In this embodiment, before the operation, first, the over-threshold shutdown module 43 preset the maximum adjustment 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, which is used to determine whether the heating power of the current feedforward compensation preheating end 3 can meet the heating requirements within the preset heating duration in the later stage. And after the heating is completed, when the humidification unit end 5 starts PID adjustment for the heating output of the atomization liquid, the output temperature detection unit 42 is used to detect whether the temperature of the atomization 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 atomization 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 adjustment of the humidification unit end 5, and the low-temperature cooperative start processing end 1 compensates and distributes the heating amount again.

[0027] In an alternative embodiment 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: 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 by the collaborative calculation value sensing module 11, and set the real-time data obtained by the temperature sensing points in each single-group humidification unit 5 as follows: ; In the formula: refers to the set of real-time data obtained by 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; Step S2: Ascend the above-obtained measurement data to obtain an ordered sequence: = ; 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; 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: ; When the number of temperature sensing points is even, substitute it into the following formula: ; In the formula, is the number of temperature sensing points; 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 , , ; Step S5: Compare the mutual difference between the set conventional PID start temperature of the humidification unit 5 and the current temperature measurement parameter value of the corresponding group respectively, and send the difference as a compensation debugging parameter to the feedforward compensation preheating end 3.

[0028] In an alternative implementation of this embodiment, the steps for the collaborative calculation value sensing module 11 to determine whether the humidification unit 5 continues to delay PID start are as follows: Step S1: Obtain the starting temperature of the humidification unit end 5 at each distribution position during the normal temperature period, and set the normal starting temperature as , , , ; Step S2: Obtain the static weights according to the influence of the temperature at the installation position of each humidification unit end 5 on the low-temperature start , , , ; Step S3: Substitute the normal temperature value into the static weights to obtain the stable measurement value: ; Step S4: Substitute the temperature measurement parameter value into the static weights to obtain the stable measurement value: ; Step S5: Compare the and numerical error values, and the delay adjustment determination module 15 determines whether the humidification unit end 5 continues to delay the PID start, that is, the delay adjustment determination module 15 determines that when 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 the 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 stop continuous heating signal to the feed-forward compensation preheating end 3, so that the feed-forward compensation preheating end 3 maintains the current temperature heating power, and sends a PID debugging start signal to the humidification unit end 5; when the delay adjustment determination module 15 determines that is higher than by more than 3.1°C, the distribution signal sending module 14 directly sends a stop heating signal to the feed-forward compensation preheating end 3, controls the humidification unit end 5 to continue to delay the PID start through the PID delay end 2, until the collaborative calculation value induction module 11 measures that the median temperature in the atomization water tank of the humidification unit end 5 drops to the interval, the PID adjustment unit in the humidification unit end 5 starts power adjustment and atomizes and outputs the atomization liquid in the atomization water tank.

[0029] In an alternative embodiment of this example, 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 startup processing end 1 reads the internal environmental temperature of each humidifying unit end 5, and the parameter interference processing module 12 is enabled to set corresponding compensation debugging parameters according to the difference between the internal environmental temperature of each humidifying unit end 5 and the atomization demand temperature. Then, the feedforward compensation preheating end 3 is allocated by the timely distribution module 13 with the compensation amount required for the low-temperature atomization startup of the humidifying unit end 5, and the time interval when each humidifying unit end 5 reaches the compensation amount is uniformly set. After that, after the feedforward compensation preheating end 3 receives the compensation amount required for each humidifying unit end 5 allocated by the timely distribution module 14 through the distribution signal issuing 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 parameter interference processing module 12. During the preheating operation stage, the startup time of the PID regulation in each humidifying unit end 5 is extended accordingly; until each humidifying unit end 5 receives the preheating compensation from the feedforward compensation preheating end 3, and its internal environmental temperature reaches the set compensation amount within the compensation time interval set by the low-temperature collaborative startup processing end 1, the internal environmental temperature of the humidifying unit end 5 reaches the normal atomization temperature value. At this time, the PID regulation in the humidifying unit end 5 is started, so that the atomized liquid preheated in each humidifying unit end 5 is quickly heated to the atomization demand 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 atomization output, the real-time temperature during the atomization output of the humidifying unit end 5 is measured by the operation monitoring end 4, and it is analyzed whether the output temperature meets the preset value, so as to confirm whether the current low-temperature startup compensation is successful.
