Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides an environmental conditioning method in a climate box, including the following steps:
s101, obtaining the temperature value in the climate box and the relative humidity value in the climate box.
In the embodiment of the present invention, the temperature value may be obtained by a temperature sensor, and the humidity value may be obtained by a humidity sensor, where a specific obtaining process is the prior art, and details of the embodiment of the present invention are not described herein.
In practical application, the climate box further comprises: the temperature adjusting unit comprises a refrigerating system, a heating system and a circulating system which are respectively connected with the controller, and the humidity adjusting unit comprises a refrigerating system, a heating system and a circulating system which are respectively connected with the controller. Temperature and humidity are adjusted through the temperature adjusting unit and the humidity adjusting unit.
S102, acquiring a preset temperature value and a preset relative humidity value.
In the embodiment of the invention, the temperature and the relative humidity are preset, the temperature and the relative humidity in the box are actually measured, the temperature in the temperature water box and the temperature in the dew point water tower are actually measured, and the dew point temperature is calculated according to the set temperature and the set relative humidity.
Specifically, the calculation of the dew point temperature is a semi-empirical formula when water vapor pressure is measured by adopting a dry bulb and wet bulb thermometer: namely, it is
And a calculation formula of relative humidity U:
wherein e is absolute humidity;
is the wet bulb temperature
The saturated water vapor pressure in hPa; a is the psychrometric constant, which is determined by the air flow rate near the wet bulb, taken 0.000667 in this calculation; p is the atmospheric pressure during monitoring, the unit is hPa, and 1000 is taken in the calculation; t' is the wet bulb temperature in units; t is the dry bulb temperature in units of;
is the saturated vapor pressure at the dry bulb temperature t, in units of hPa; u is relative humidity, expressed in percentage.
Wherein, the saturated water vapor pressure formula adopts an empirical formula-Tetens formula:
it should be noted that, in the specific calculation, an initial value, specifically a set temperature, is first given to the dry bulb temperature t, and substituted into the set temperature
The saturated vapor pressure under the set temperature condition is obtained, and then an initial value is assumed to be the wet bulb temperature t', and is substituted into
The actual water vapor pressure is obtained and substituted into the calculation
And calculating the difference value between the U value and the set relative humidity value;
if the difference is greater than the set error, the assumed wet bulb temperature is adjusted
Performs corresponding increase or decrease processing, and returns to assume an initial value for the wet bulb temperature t', substitutes
The step of obtaining the actual water vapor pressure is executed again; until the difference between the U value and the set relative humidity value is within the set error range, and the assumed wet bulb temperature is at the moment
I.e. the dew point temperature.
That is, the formula is substituted to obtain a corresponding relative humidity value (specifically, the formula may be labeled, for example, as a relative humidity value 1), the difference between the set relative humidity value and the relative humidity value 1 obtained at this time is compared, the wet bulb temperature value t' is adjusted according to the difference, iteration is performed in such a way until the difference between the relative humidity values reaches an allowable error range, and the wet bulb temperature used for calculation is the dew point temperature at this time.
S103, calculating the absolute value of the temperature difference between the temperature value in the box and the set temperature value and the absolute value of the humidity difference between the relative humidity value in the box and the set relative humidity value.
In the embodiment of the invention, in order to facilitate the comparison of the temperature and humidity difference values inside and outside the box, the temperature and humidity difference values are usually compared with a set temperature value or a set temperature and humidity so as to determine the corresponding difference values. In the specific calculation, the desired internal temperature value and the set temperature value are directly subtracted to obtain the difference.
As shown in fig. 3 to 5, a product term P is set by comparing the difference between the set temperature and the internal temperature with an error threshold, and when the product term P is greater than 1, it indicates that the error threshold is smaller than the difference between the set temperature and the internal temperature, and when the product term P is equal to 1, it indicates that the error threshold is equal to the difference between the set temperature and the internal temperature; when the product term P is less than 1, the error threshold is larger than the difference between the set temperature and the internal temperature.
In practical applications, then, the following two categories are available: the temperature in the box is greater than a set temperature value, and the absolute value of the difference value between the temperature in the box and the set temperature value is greater than a set temperature error threshold value;
or the temperature in the box is less than a set temperature value, and the difference value between the temperature in the box and the set temperature value is greater than a set temperature error threshold value.
And S104, starting temperature control of the temperature water tank according to the proportion of the absolute value of the difference value under the condition that the calculated absolute value of the temperature difference value is not less than the temperature error threshold, and performing dehumidification or humidification treatment according to the self-circulation system of the water tower and the refrigeration system under the condition that the calculated absolute value of the humidity difference value is not less than the humidity error threshold.
As shown in fig. 3, the measured temperature in the tank is greater than the set temperature, and a difference between the measured temperature and the set temperature is obtained, and when the difference is greater than the set temperature error threshold, that is, P is greater than 1, the proportional refrigeration control of the temperature tank is started according to the proportion of the difference. When the primary refrigeration time is up, the temperature water tank refrigeration system is closed, and the system self-circulates for 3 minutes. And after 3 minutes, judging the difference value between the measured temperature in the box and the set temperature again, comparing the difference value with the set temperature error threshold value, starting the proportional refrigeration control again according to the difference value of the measured temperature and the set temperature, and circulating the steps until the difference value between the measured temperature in the box and the set temperature is not more than the set temperature error threshold value.
When the temperature water tank is cooled, the difference value between the relative humidity in the actual measurement tank and the set relative humidity is judged, and when the difference value exceeds the set relative humidity error threshold value and humidification is needed, only a dew-point water tower self-circulation system is started; when the difference value exceeds the set relative humidity error threshold value and the humidity needs to be reduced, starting a dew point water tower refrigeration system until the temperature of the dew point water tower reaches a refrigeration lower limit value; and when the difference value does not exceed the set relative humidity error threshold value, carrying out the proportional refrigeration control of the dew-point water tower according to the refrigeration proportion of the temperature water tank.
In the embodiment of the invention, the starting and stopping interval of the refrigerating system is 3 minutes, so that the frequent starting of the refrigerating compressor is avoided, and the protection effect is achieved. The temperature water tank is started in a self-circulation mode within 3 minutes of the closing of the refrigerating system, so that fluctuation caused by temperature hysteresis is reduced, and the energy consumption of the system is reduced.
It should be noted that the humidity control is based on the characteristics of the dew point temperature control method, that is, the temperature in the tank is constant, the dew point temperature is increased, the relative humidity is increased, the dew point temperature is decreased, and the relative humidity is decreased, to control the temperature of the temperature water tank and the dew point water tower, so that the system can reach the stable state quickly. Because the whole system structure of the climate box is different from a standard dew point water tower humidity control system, the calculated dew point temperature is used as a reference lower limit value of refrigeration control of the dew point water tower.
As shown in fig. 4, when the measured temperature in the tank is less than the set temperature and the difference is greater than the set temperature error threshold, the proportional heating control of the temperature tank is started according to the proportion of the difference, when the heating time reaches one time, the heating system of the temperature tank is closed, the system self-circulates for 2 minutes, and after 2 minutes, the difference between the measured temperature in the tank and the set temperature is judged again and compared with the set temperature error threshold, and the proportional heating control is started again according to the difference between the measured temperature and the set temperature, and the process is circulated until the difference between the measured temperature in the tank and the set temperature is within the range of the set temperature error threshold.
When the temperature water tank is heated, the difference value between the relative humidity in the actual measurement tank and the set relative humidity is judged, when the difference value exceeds the set relative humidity error threshold value and the humidity is required to be reduced, the difference value is compared with the humidity reduction threshold value, when the difference value is large, the proportional refrigeration control is started until the temperature of the dew-point water tower reaches the refrigeration lower limit value, and when the difference value is small, the self-circulation system of the dew-point water tower is only started; when the difference exceeds the set relative humidity error threshold and humidification is needed, proportional heating control is started when the difference is large, and only a dew-point water tower self-circulation system is started when the difference is small.
In the embodiment of the invention, the self-circulation mode is started within 2 minutes of the closing of the heating system, so that the fluctuation caused by temperature hysteresis is reduced, and the energy consumption of the system is also reduced. The control of humidity is according to the characteristics of dew point control temperature method, and temperature water tank and dew point water tower are controlled to make the system reach steady state fast according to the characteristics that the temperature in the tank is unchanged, the dew point temperature rises, the relative humidity increases, the dew point temperature decreases, and the relative humidity decreases.
It should be noted that, because the overall system structure of the climate box is different from that of a standard dew point water tower humidity control system, the calculated dew point temperature is used as a reference lower limit value of the refrigeration control of the dew point water tower and is not used as a final target value.
And S105, under the condition that the calculated absolute value of the temperature difference is not larger than the temperature error threshold, stabilizing temperature balance control and simultaneously adopting a heating system or a refrigerating system to adjust humidity according to the absolute value of the humidity difference.
And when the difference value between the actually measured temperature in the box and the set temperature is not greater than the set temperature error threshold, starting a control method for balancing threshold proportional temperature control to enable the temperature in the box to be always stabilized within the range of the set temperature error threshold.
When the temperature balance control is stabilized, the difference value between the relative humidity in the actual measurement box and the set relative humidity is judged, when the difference value exceeds the set relative humidity error threshold value and the humidity is required to be reduced, the proportional refrigeration control is started when the difference value is large until the temperature of the dew-point water tower reaches the refrigeration lower limit value, and the dew-point water tower proportional refrigeration control is carried out according to the refrigeration proportion of the temperature water tank when the difference value is small; and when the difference exceeds a set relative humidity error threshold and humidification is needed, starting proportional heating control when the difference is large, and performing proportional refrigeration control of the dew-point water tower according to the refrigeration proportion of the temperature water tank when the difference is small.
It should be noted that, when the temperature and the relative humidity reach the equilibrium state, the refrigeration system and the heating system are stopped for 3 minutes and 2 minutes, and the system self-circulation is started within the stop time. When the stop time is up, the temperature threshold value proportion control of the temperature and the relative humidity is started to keep the error of the temperature and the relative humidity within the set error range. The starting and stopping interval of the refrigerating system is 3 minutes, so that the frequent starting of the refrigerating compressor is avoided, and the protective effect is achieved. And the self-circulation mode is started within 3 minutes after the refrigeration system is closed, so that the fluctuation caused by temperature hysteresis is reduced, and the energy consumption of the system is reduced. The self-circulation mode is started within 2 minutes of the shutdown of the heating system through the dew-point water tower, so that the fluctuation caused by temperature hysteresis is reduced, and the energy consumption of the system is reduced.
It can be understood that the control of the humidity is based on the characteristics of the dew point temperature control method, namely, the characteristics that the temperature in the box is unchanged, the dew point temperature is increased, the relative humidity is increased, the dew point temperature is reduced and the relative humidity is reduced are adopted to control the temperature of the temperature water box and the dew point water tower, so that the system can reach a stable state quickly.
In the embodiment of the invention, the whole system structure of the climate box is different from a standard dew point water tower humidity control system, so the calculated dew point temperature is used as the reference lower limit value of the refrigeration control of the dew point water tower and is not used as the final target value.
Furthermore, as shown in fig. 6, the present invention also discloses an environmental conditioning apparatus 600 in a climate box, wherein the apparatus 600 comprises a processor 610, and a memory 620 connected to the processor 610 through a communication bus 630; wherein,
