In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 2, it is a schematic diagram of an implementation flow of an air conditioner control method provided in an embodiment of the present invention, where the method is applied to variable air volume control of an air conditioner terminal unit, and as shown in the figure, the method may include the following steps:
and step S201, acquiring a difference value between the return air temperature and the supply air temperature of the air conditioning unit.
In the embodiment of the invention, the return air temperature is the temperature of the return air inlet of the air conditioner, and some air can be returned into the air conditioning box by utilizing the return air channel of the air conditioner and mixed with a small amount of fresh air to prepare cold air which is sent into a room; the air supply temperature is the temperature of cold air or hot air blown out from the air outlet when the air conditioner is in operation, is not the temperature of a room, and can be influenced by the air supply amount to a certain extent.
In addition, when the area load changes, the return air temperature also changes, and the difference between the return air temperature and the supply air temperature of the air conditioning unit affects the supply and demand balance of the area load and the power of the blower.
And step S202, calculating the air supply quantity according to the difference under the condition of ensuring constant air supply temperature.
In the embodiment of the invention, when the return air temperature and the air supply temperature are kept stable, the cooling capacity of the air conditioning unit can be changed by adjusting the air supply capacity, so that the balance of supply and demand of regional load and the energy conservation of the air feeder can be ensured.
In addition, the variable air volume control adds the variable frequency driver of the air feeder and the air feeding temperature sensor in the tail air conditioning unit, so that the fan of the air conditioning unit can run in variable air volume; in the case of load change in the terminal area, the cooling load can be changed by adjusting the air supply amount and the chilled water valve so as to keep the load balance.
It should be noted that, under the variable air volume control logic, the following formula is satisfied:
Q＝G·C·(Ttemperature of return air-TTemperature of the air supply)
Q: area load
G: air quantity (controllable variable)
C: specific heat of air
When the area load Q changes, TTemperature of return airAnd the air supply quantity required to be adjusted can be calculated according to the difference value of the return air temperature and the air supply temperature under the condition that the air supply temperature is stable and the comfort of the regional environment is ensured.
Preferably, the calculating the air supply amount according to the difference value under the condition that the air supply temperature is kept constant includes:
step S2021, taking the detected return air temperature as a return air temperature feedback value;
and step S2022, performing Proportional Integral Derivative (PID) regulation on the rotating speed of the air feeder according to the difference value between the return air temperature feedback value and the return air temperature set value.
In the embodiment of the invention, the return air temperature of the cold supply area of the air conditioning unit is detected, and the closed-loop control is performed on the return air temperature, for example, in a return air temperature closed-loop control part in a schematic flow chart of the air conditioning control logic provided by the embodiment of the invention shown in fig. 3, the feedback value of the return air temperature is compared with the set value of the return air temperature to obtain the difference value of the feedback value and the set value of the return air temperature, and the air quantity of the air feeder is controlled by performing proportional-derivative-integral (PID) control on the difference value, so that the return air temperature is returned to the set value and is kept stable with the air supply temperature, the comfort of the area environment is ensured, and meanwhile.
Step S203, determining whether the calculated air volume is within a preset air volume interval.
In the embodiment of the invention, the preset air supply volume interval comprises the upper limit rotating speed and the lower limit rotating speed of the fan; the setting of the air supply volume interval is determined by the rated air volume of the fan and the requirement of the most remote static pressure of the cooling area, the required air supply volume is calculated according to the difference between the return air temperature and the air supply temperature and the load requirement of the cooling area, and if the calculated air supply volume is in the preset air supply volume interval, the fan is directly driven by the variable frequency driver to change the rotating speed, so that the air supply volume is adjusted.
And step S204, if the calculated air supply volume is outside the air supply volume interval, adjusting the air supply temperature set value.
In the embodiment of the invention, if the calculated air supply quantity exceeds the range of the air supply quantity interval, the rotating speed of the fan cannot be changed by the variable frequency driver to adjust the air supply quantity, but the set value of the air supply temperature can be adjusted to ensure the stability of the air supply temperature; as shown in the air supply setting temperature self-adjusting part of the logic flow diagram of the air conditioner control shown in fig. 3, the set value of the air supply temperature can be adjusted according to the set limit value of the air supply temperature, and the set limit value of the air supply temperature can be obtained from the initial value of the air supply temperature and the adjusted value of the air supply temperature.
Preferably, if the calculated air volume is outside the air volume interval, adjusting the air supply temperature setting value includes:
step S2041, if the rotating speed of the air blower is greater than or equal to the set upper limit rotating speed and the cooling capacity supplied by the air conditioning unit is less than the actual regional requirement, reducing the set value of the air supply temperature;
in the embodiment of the invention, if the rotating speed of the running fan is greater than or equal to the set upper limit rotating speed, the air volume cannot be increased by increasing the rotating speed of the fan, and meanwhile, if the cooling capacity supplied by the air conditioning unit is smaller than the actual load requirement of the area, the area temperature can be gradually increased to be higher than the set temperature of the area, and the rotating speed of the fan cannot be reduced, so that the cooling capacity needs to be increased by reducing the set value of the air supply temperature, the set temperature of the area is recovered, the energy saving can be realized by correspondingly reducing the rotating speed of the fan, and the adjustment value T of the air supply temperature is obtainedAir supply temperature adjustment valueFurther with the initial value T of the supply air temperatureInitial value of air supply temperatureCombined with obtaining a set limit value T for supply air temperatureAir supply temperature setting limit。
And step S2042, if the rotating speed of the air blower is less than or equal to the set lower limit rotating speed and the cooling capacity supplied by the air conditioning unit is greater than the actual regional requirement, increasing the set value of the air blowing temperature.
In the embodiments of the present inventionIf the rotating speed of the running fan is less than or equal to the set lower limit rotating speed, the air quantity can not be reduced by continuously reducing the rotating speed of the fan, meanwhile, the cooling capacity of the air conditioning unit is greater than the actual load demand of the area, the area temperature is gradually reduced to be lower than the set temperature, the cooling capacity can be reduced by increasing the set value of the air supply temperature through proportional-integral PI control, the area is recovered to the set temperature, and the adjustment value T of the air supply temperature is obtainedAir supply temperature adjustment valueFurther with the initial value T of the supply air temperatureInitial value of air supply temperatureCombined with obtaining a set limit value T for supply air temperatureAir supply temperature setting limit。
Further, the method for optimizing and controlling the central air-conditioning terminal unit further comprises the following steps:
step S301, using the detected air supply temperature as an air supply temperature feedback value;
and step S302, performing Proportional Integral Derivative (PID) adjustment on the chilled water valve according to the difference value between the air supply temperature feedback value and the air supply temperature set value.
In the embodiment of the invention, in order to ensure the comfort of the regional environment, the air supply quantity can be adjusted by closed-loop control on the return air temperature, the temperature can be self-adjusted according to the air supply setting, the set value of the air supply temperature can be adjusted according to the working condition of the fan, and the closed-loop control on the air supply temperature can be performed.
Taking the detected air supply temperature as an air supply temperature feedback value, performing Proportional Integral Derivative (PID) control according to the difference value between the air supply temperature feedback value and the air supply temperature set value, and adjusting a cold water valve to ensure the stability of the air supply temperature, as shown in fig. 3; through the closed-loop control of the air supply temperature, the problem that the comfort of the air conditioner nearby an air supply outlet is insufficient due to frequent change of the air supply temperature when an air conditioner user uses the air conditioner is solved.
According to the embodiment of the invention, the air quantity is changed to optimally control the air conditioning tail end unit, the air supply quantity can be adjusted according to the return air temperature difference, the heat exchange quantity of the cold water coil pipe can be adjusted according to the air supply temperature difference, and the air supply temperature set value can be adjusted according to the working condition of the fan, so that the comfort of the air conditioner is improved, the supply and demand balance of regional load is kept, and the energy consumption of the air conditioning unit is reduced.
