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 obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Example one
Referring to fig. 1, a combined fresh air conditioning control method for a data center according to an embodiment of the present invention includes the following steps S101 to S103:
s101: and acquiring the environmental information.
As a preferable solution of this embodiment, the environment information includes: indoor temperature and humidity, outdoor temperature and humidity, indoor air pressure and outdoor air pressure.
It should be noted that the acquisition of the environmental information is realized by various sensors, including but not limited to a temperature and humidity sensor, a differential pressure sensor, and the like. Meanwhile, the temperature and humidity sensors and the differential pressure sensors which are arranged at different positions can acquire the environmental information of the approximate areas at different positions, and the arranged positions comprise indoor areas, outdoor areas, air conditioner air supply outlets and the like.
S102: judging the operation mode of the air conditioner according to the environment information; the operating modes include dew point temperature control, humidity control, and differential pressure control.
It should be noted that, for the acquired environment information, the environment information can be processed to obtain a corresponding operation mode, for example, in this embodiment, after the outdoor environment temperature and humidity are measured by the temperature and humidity sensor, the measured data is input into the calculation formula of the dew point temperature, so that the operation mode of the air conditioner can be determined according to the dew point temperature. Wherein the calculation formula of the dew point temperature is a Goff-Gratchy (Goff-Gratch) formula:
wherein T is the absolute temperature (unit: K); ew is the saturated vapor pressure (unit: hPa) of the level surface of pure water.
Further, as an exemplary scheme of this embodiment, the dew point temperature of the fresh air of the air conditioner is set to 12 ℃ as a determination mode of the operation condition of the air conditioner, and when the dew point temperature is greater than 12 ℃, the current operation mode of the air conditioner is output and displayed as a summer condition, that is, the air conditioner enters an operation mode targeting cooling and dehumidification, and a target value of the dew point temperature is used as a control value, that is, the dew point temperature is controlled; when the dew point temperature of the outdoor fresh air is lower than 12 ℃, outputting the current air conditioner operation working condition as an excessive working condition, and controlling the air conditioner by taking the supplied air humidity as a target control value, namely humidity; when the humidity of the outdoor fresh air is smaller than the humidity target value and the dew point temperature of the fresh air is smaller than the 12 ℃ dew point temperature judgment value, the current air conditioner operation working condition is output as a winter working condition, and the winter working condition is converted into a control mode of taking indoor pressure difference as a control mode, namely pressure difference control.
S103: and controlling the operation of an electric valve or a motor of the air conditioner according to the operation mode of the air conditioner.
As a preferable aspect of this embodiment, the controlling the operation of the electric valve or the motor of the air conditioner according to the operation mode of the air conditioner specifically includes:
when the operation mode of the air conditioner is dew point temperature control, controlling the opening of an electric valve of the air conditioner; when the operation mode of the air conditioner is humidity control, controlling the opening of an electric valve of the air conditioner; and when the operation mode of the air conditioner is pressure difference control, controlling the rotating speed of the air conditioner motor.
It can be understood that the corresponding electric valve or motor of the air conditioner is correspondingly controlled through different air conditioner operation modes, so that the function diversification can be finely controlled, the control errors under different air conditioner operation modes are reduced, and the air conditioner control accuracy is improved.
As a preferable aspect of this embodiment, when the operation mode of the air conditioner is dew point temperature control, controlling the opening of an electrically operated valve of the air conditioner specifically includes:
and when the operation mode of the air conditioner is dew point temperature control, calculating the dew point temperature according to the environment information, comparing the dew point temperature with a preset dew point temperature, and outputting an opening control instruction of an electric valve of the air conditioner.
It should be noted that, when the dew point temperature of the real-time air supply is greater than the target value of the preset dew point temperature, the opening of the electric water valve of the fresh air combined air conditioner is continuously increased to output on the basis of the opening of the existing electric water valve to perform refrigeration and dehumidification, and the opening of the electric water valve is up to 100% of the maximum value (the requirement of refrigeration and dehumidification can be met when the opening of the electric water valve is up to 100%), and the opening of the electric water valve of the maximum electric water valve is maintained until the dew point temperature of the real-time air supply drops, and when the dew point temperature of the air supply is less than or equal to the target value of the preset dew point temperature, the fresh air combined air conditioner reduces the opening of the electric water valve of the fresh air combined air conditioner according to the control requirement of the dew point temperature target value, tracks the change of the dew point temperature target value and the real-time dew point temperature value in real time, and continuously adjusts the opening of the electric water valve to meet the requirement that the opening drops to 0% or the dew point temperature of the real-time air supply remains within the dew point temperature target value range of the dew point temperature.
Furthermore, in order to prevent the opening of the electric water valve of the air conditioner from being frequently opened and closed, the target value of the dew point temperature is set to be 1 ℃ of return difference so as to ensure the stability of the electric water valve.
It can be understood that when the operating mode of the air conditioner is dew point temperature control, the dew point temperature is calculated according to the environmental information, and then after the dew point temperature is compared with the preset dew point temperature, an opening control instruction of the air conditioner electric valve is output, so that the operating mode of the air conditioner during dew point temperature control is accurately controlled.
As a preferable aspect of this embodiment, when the operation mode of the air conditioner is humidity control, controlling the opening of the electrically operated valve of the air conditioner specifically includes:
and when the operation mode of the air conditioner is humidity control, obtaining the air supply humidity corresponding to the current dew point temperature according to the environment information, and outputting an opening control instruction of an electric valve of the air conditioner according to the air supply humidity.
When the real-time air supply humidity is less than or equal to the preset air supply humidity target value, the opening of the electric water valve of the fresh air combined air conditioner is reduced until the opening of the electric water valve is reduced to 0% or the real-time air supply humidity is controlled within the air supply humidity target value range.
And if the real-time air supply humidity rises in the opening adjusting and closing process of the electric water valve, outputting a control command again to improve the opening of the electric water valve for refrigeration and dehumidification, and maintaining the real-time air supply humidity within the target humidity. Furthermore, a 5% return difference is set for preventing the opening of the electric water valve of the air conditioner from generating frequent on-off state humidity target values, so as to ensure the stability of the electric water valve.
It can be understood that when the operation mode of the air conditioner is humidity control, the air supply humidity corresponding to the current dew point temperature is obtained according to the environment information, and then the opening control instruction corresponding to the air conditioner electric valve is output according to the numerical value of the air supply humidity, so that the operation mode of the air conditioner during humidity control is accurately controlled.
As a preferable scheme of this embodiment, when the operation mode of the air conditioner is the pressure difference control, the rotation speed of the air conditioner motor is controlled, specifically:
and when the operation mode of the air conditioner is pressure difference control, obtaining a real-time indoor pressure difference value according to the environment information, and outputting an air conditioner motor rotating speed control instruction according to the pressure difference value.
It should be noted that, when the indoor real-time differential pressure is smaller than the target differential pressure value, the control command of the air conditioner motor is output, the frequency of the air conditioner motor is increased (that is, the rotation speed of the motor is increased), the air supply amount of the air conditioner is increased until the rotation speed of the air conditioner motor reaches 100% (or the motor frequency is 50 Hz), and the maximum rotation speed is maintained. When the indoor real-time pressure difference begins to rise, and the real-time pressure difference is larger than or equal to the target pressure difference value, the rotating speed of the air-conditioning motor is reduced, the air-conditioning motor is maintained within the lowest allowable rotating speed range, or the indoor pressure difference is stabilized within the target pressure difference value range, the air-conditioning motor tracks the indoor real-time pressure difference value in real time, the rotating speed output of the motor is continuously adjusted, and the stability of the indoor pressure difference value is guaranteed.
When the indoor real-time pressure difference is larger than the target pressure difference value, outputting a control command of the air conditioner motor, reducing the rotating speed of the air conditioner motor, and reducing the air supply quantity of the air conditioner until the rotating speed of the air conditioner motor is in the lowest allowable rotating speed range and is maintained in the lowest rotating speed range or the indoor real-time pressure difference is stabilized in the target pressure difference value range. If the indoor real-time differential pressure value is smaller than the target differential pressure value in the process of adjusting the rotating speed of the motor, the air conditioner improves the rotating speed of the motor of the air conditioner according to the logic, and the indoor differential pressure value is controlled within the range of the target differential pressure value repeatedly and continuously.
It can be understood that when the operation mode of the air conditioner is the differential pressure control, the real-time differential pressure value corresponding to the current indoor is obtained according to the environmental information, and then the control instruction corresponding to the rotating speed of the motor of the air conditioner is output according to the differential pressure value, so that the operation mode of the air conditioner during the differential pressure control is accurately controlled.
