Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described more fully below by way of examples in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In one embodiment, referring to fig. 1, there is provided an air conditioner air supply amount adjusting method, comprising the steps of:
step S100: and acquiring a required energy value of the air conditioner and the space volume of the target area, wherein the required energy value is the energy consumed when the ambient temperature of the target area reaches a set temperature.
Specifically, the specific value of the required energy value changes with the change of the ambient temperature and the set temperature, generally speaking, the larger the difference between the ambient temperature and the set temperature, the more energy that needs to be consumed correspondingly when the ambient temperature is increased or decreased from the current temperature to the set temperature by the air conditioner through the heating or cooling operation mode, the larger the required energy value, conversely, the smaller the difference between the ambient temperature and the set temperature, the less energy that needs to be consumed correspondingly when the ambient temperature is increased or decreased from the current temperature to the set temperature by the air conditioner through the heating or cooling operation mode, the smaller the required energy value. The volume of the target area is an important parameter affecting the working effect of the air conditioner, and generally, the larger the spatial volume of the target area is, the heavier the air conditioner is, and the worse the corresponding cooling or heating effect is.
The method for obtaining the required energy value of the air conditioner is not unique, for example, after the air conditioner is turned on, the ambient temperature of the target area is detected, the target temperature set by the user is received, and the required energy value is obtained by calculation according to the ambient temperature and the target temperature. The device for detecting the ambient temperature of the target area is not unique, for example, a temperature controller may be adopted, the temperature controller detects the temperature of the target area and converts the detected signal into an electrical signal, and the ambient temperature value of the target area may be obtained by analyzing the obtained electrical signal. The temperature controller detection process is convenient, the use cost of the device is low, and it can be understood that in other embodiments, other devices can be used for detecting the ambient temperature of the target area, as long as the detection can be realized by those skilled in the art. The value of the spatial volume of the target region is not unique, and may be set when the air conditioner is installed, or may be an updated value of the target region input again during use by the user, and may be called directly during use. The number of the target areas is not unique, for a regional control system, the air conditioning unit can supply air to a plurality of areas, the space volume, the ambient temperature and the set temperature of each target area can be different, and during calculation, the parameters collected by the current target area are used as the standard.
Step S200: and calculating the required time consumed for the environment temperature of the target area to reach the set temperature according to the required energy value and the space volume.
Specifically, the specific value of the demand time varies with the change of the demand energy value and the space volume of the target area, and generally, the larger the demand energy value is, or the larger the volume of the target area is, the more energy needs to be consumed when the ambient temperature of the target area reaches the set temperature, and the longer the time taken for the ambient temperature of the target area to reach the set temperature is, the longer the demand time is. Conversely, the smaller the required energy value is, or the smaller the volume of the target region is, the smaller the required time is, the size of the required time is reflected by the required energy value and the size of the space volume of the target region, and a specific value of the required time can be calculated based on the required energy value and the space volume of the target region. The manner of calculating the demand time from the demand energy value and the space volume is not exclusive, and for example, a quotient obtained by dividing the demand energy value by the space volume is a value of the demand time. It is understood that in other embodiments, the required time may be calculated in other manners, as long as the skilled person realizes.
Step S300: and when the required time is less than the preset starting time sequence duration, reducing the air supply quantity of the air conditioner.
Specifically, the startup timing time refers to a duration that the air conditioner must be continuously started after being started, and when the startup time does not reach the duration, the air conditioner cannot be turned off. The duration time of the starting time sequence is preset before the air conditioner is started, and the specific value can be adjusted according to actual requirements. Taking the local control system as an example, the startup time sequence can be directly obtained from the control terminal of the local control system. In a regional control system, the air conditioning unit has a time sequence requirement of starting 6 and stopping 3, namely the air conditioning unit is required to be continuously started for 6 minutes to be shut down after being started, and is required to be continuously closed for 3 minutes to be opened after being shut down, so that the starting time sequence time is 6 minutes, and the arrangement can prevent the compressor from being damaged by frequent starting and stopping of the compressor. When the required time is less than the preset starting time sequence time, the time required for the environment temperature of the target area to reach the set temperature is less than the starting time sequence time, if the set temperature is reached according to the initial working state, the air conditioner cannot be shut down and can continue to be in the current working mode, when the working mode of the air conditioner is the refrigeration mode, the environment temperature can be continuously reduced to be below the set temperature, and when the working mode of the air conditioner is the refrigeration mode, the environment temperature can be continuously increased to be above the set temperature, so that the temperature is too high or too low. At the moment, the air supply quantity of the air conditioner is controlled to be reduced, the air conditioner can continue to work after the ambient temperature reaches the set temperature, the air supply quantity of the air conditioner is controlled to be reduced under the condition, specifically, the air supply quantity of the air conditioner is reduced before the running time of the air conditioner reaches the required time, smoothness control is carried out on the air supply quantity of the air conditioner, the time spent by the ambient temperature reaching the set temperature from the current temperature is prolonged, when the air conditioner is started to reach the duration time of the starting time sequence, the difference between the actual ambient temperature and the set temperature can be reduced, on the premise that the temperature setting requirement of a user is guaranteed, the temperature of a target area is prevented from being too high or too low, the resource waste of the air conditioner is.
In one embodiment, referring to fig. 2, step S100 includes step S110 and step S120.
Step S110: and acquiring the air volume, the air specific gravity, the air constant pressure specific heat, the air conditioner inlet and outlet temperature difference and the space volume of a target area.
Specifically, the air conditioner air volume refers to the air volume of the air conditioner and changes according to the working load state of the air conditioner. The specific gravity value of the air is generally equal to the density of the air, the specific value can be adjusted according to the actual situation, and generally can be 1.293kg/m3The air constant-pressure specific heat is the heat required for increasing the temperature of a certain substance per unit mass by 1 Kelvin under the condition of constant pressure, and the air specific heat has no fixed value and can change even under the condition of constant temperature, so the air constant-pressure specific heat is used for reflecting the size of the air specific heat. The specific value of the air constant pressure specific heat can be 1.005kJ/kg, and can also be adjusted according to actual requirements. The temperature difference between the inlet and the outlet of the air conditioner is Kelvin temperature, and can be obtained by conversion according to the temperature in centigrade:
T＝t+273.15 (1)
wherein T is Kelvin temperature and is represented by K, T is centigrade and is represented by 1K, the centigrade temperature obtained by conversion is-272.15 ℃, and the Kelvin temperature obtained by conversion is 274.15K, represented by 1 ℃.
Step S120: and calculating according to the air volume, the air specific gravity, the air constant pressure specific heat and the air conditioner inlet and outlet temperature difference of the air conditioner to obtain the required energy value of the air conditioner.
Specifically, the specific value of the required energy value changes with the change of the air conditioning air volume, the air specific gravity, the air constant pressure specific heat and the air conditioner inlet and outlet temperature difference, generally speaking, the larger the air conditioning air volume, the air specific gravity, the air constant pressure specific heat or the air conditioner inlet and outlet temperature difference is, the more energy is consumed when the ambient temperature of the target area reaches the set temperature, and the larger the required energy value is, and conversely, the smaller the air conditioning air volume, the air specific gravity, the air constant pressure specific heat or the air conditioner inlet and outlet temperature difference is, the less energy is consumed when the ambient temperature of the target area reaches the set temperature, and the smaller the required energy value is, and the required energy value can be calculated based on the air conditioning air volume, the air specific gravity, the air constant pressure specific heat and the air. The method for calculating the required energy value according to the air volume, the specific gravity, the specific heat at constant pressure and the temperature difference between the inlet and the outlet of the air conditioner is not exclusive, and for example, the following formula can be adopted for calculation:
P＝q*ρ*cp*△t (2)
wherein, P is the required energy value with the unit of W, q is the air conditioning air volume with the unit of m3Rho is the specific gravity of air in kg/m3When the air conditioner is used, the parameters are directly obtained from the air conditioner, wherein the temperature difference between the inlet and the outlet is obtained according to the collected ambient temperature and the set temperature.
In one embodiment, referring to fig. 2, step S200 includes step S210 and step S220.
Step S210: and calculating to obtain the initial demand time according to the demand energy value and the space volume.
The initial demand time refers to time obtained by calculation when the air conditioner is started, the initial demand time is obtained by calculation according to the space volume of a demand energy value target area, after a target temperature is set by a user, the demand energy value is calculated according to the difference value between the environment temperature and the target temperature, and the initial demand time can be obtained by calculation according to the volume of the obtained target area.
Step S220: and calculating the required time consumed by the environment temperature of the target area to reach the set temperature according to the initial required time and a preset correction coefficient.
After the initial demand time is obtained, the initial demand time can be corrected according to a preset correction coefficient so as to obtain more accurate demand time, and the preset correction coefficient is directly called when the device is used. The preset correction coefficient is not acquired in a unique manner, and may be a correction coefficient calculated when the air conditioner is started last time. It is understood that in other embodiments, the preset correction coefficient may be obtained in other manners, such as directly set by a user, etc., as long as the implementation is considered by those skilled in the art.
In one embodiment, referring to fig. 2, after step S200, step S400 is further included.
Step S400: and updating the correction coefficient according to the corresponding relation among the space volume, the required energy value and the required time.
Specifically, the correction coefficient may be updated by obtaining data after the air conditioner is turned on for multiple times, for example, the data is obtained according to a fitting result of a corresponding relationship between a required energy value obtained after the air conditioner is turned on, a spatial volume of a target area, and a required time, after the air conditioner is turned on and off for multiple times, the correction coefficient of each time is counted, and the updated correction coefficient is obtained by taking an average value of historical correction coefficients and the like. And calculating to obtain the required time by using the updated correction coefficient, the required energy value and the space volume after the air conditioner is started next time.
Taking a multi-zone control system as an example, the calculation method of the demand time may be:
T1＝(P/V)*α+β (3)
wherein T1 is the demand time, P is the demand energy value, which may be the demand energy value during cooling or the demand energy value during heating, V is the space volume of the target zone, which is set by the zone controller, α, β are correction coefficients, and after each start-up of the unit, the relationship between P, V and T1 is calculated in the zone control terminal, and correction coefficients α and β are generated for calculating T1 next time.
In one embodiment, referring to fig. 2, after step S200, step S500 is further included.
Step S500: and when the required time is longer than or equal to the preset starting time sequence duration, keeping the air supply quantity of the air conditioner unchanged.
When the required time is greater than or equal to the preset starting time sequence time, the time required by the environment temperature of the target area to reach the set temperature is greater than or equal to the starting time sequence time, if the set temperature is reached according to the initial working state, the starting time length of the air conditioner is greater than the starting time sequence duration, the air conditioner can be turned off, the temperature of the target area cannot be continuously increased or reduced due to continuous working of the air conditioner, and therefore the air supply quantity of the air conditioner is kept unchanged.
In one embodiment, referring to fig. 3, step S300 includes step S310.
Step S310: and when the required time is less than the duration time of the starting sequence, reducing the opening degree and/or the opening number of the air valve of the target area so as to reduce the air supply quantity of the air conditioner.
The manner of reducing the air-conditioning air blowing amount is not exclusive, and in the present embodiment, the air-conditioning air blowing amount may be reduced by reducing the damper opening degree of the target zone. The opening degree of the air valve has different levels, and the air supply amount corresponding to different levels is different, and generally, the larger the opening degree of the air valve is, the larger the air supply amount is, and the smaller the opening degree of the air valve is, the smaller the air supply amount is. Taking the example that the opening degree of the air valve includes 0, 20%, 30%, 50% … 100%, etc., when the opening degree of the air valve is 0, the air valve is completely closed and the air valve cannot supply air, and when the opening degree of the air valve is 100%, the air valve is completely opened, and at this time, the air supply amount of the air valve is maximum. The air supply quantity of the air conditioner can be adjusted by adjusting the opening degree of the air valve, so that the time required by the ambient temperature of the target area to reach the target temperature is taken as an example under the heating mode of the air conditioner, when the heating quantity is fixed, if the opening degree of the air valve is 100%, the heat can be provided in 10 minutes, and if the opening degree of the air valve is 50%, the heat can be provided in 20 minutes. In addition, the air supply quantity of the air conditioner can be reduced by reducing the opening number of the air valves, and when a plurality of air valves are arranged in a target area, the air valves can be partially closed to reduce the opening number of the air valves so as to achieve the purpose of reducing the air supply quantity of the air conditioner. By reducing the opening degree of the air valves or the opening number of the air valves, the demand time can be prolonged, the time spent by the ambient temperature reaching the set temperature from the current temperature is prolonged, when the air conditioner is started to reach the duration time of the starting time sequence, the difference between the actual ambient temperature and the set temperature can be reduced, the temperature of a target area is prevented from being too high or too low, and the use reliability of the air conditioner air supply quantity adjusting method is improved.
In one embodiment, referring to fig. 3, step S300 includes step S320.
Step S320: and when the required time is less than the duration time of the starting sequence, reducing the frequency of a compressor of the air conditioner so as to reduce the air supply quantity of the air conditioner.
The compressor frequency is one of important parameters affecting the operation performance of the air conditioner, and generally, the larger the compressor frequency is, the better the cooling or heating performance of the air conditioner is, and the smaller the compressor frequency is, the worse the cooling or heating performance of the air conditioner is. When the required time is less than the duration time of the starting sequence, if the current compressor frequency is maintained, the target area continues to refrigerate or heat after the ambient temperature reaches the set temperature, so that the temperature of the target area exceeds or is lower than the set temperature, the compressor frequency is controlled to be reduced at the moment, the required time can be prolonged, when the air conditioner is started to reach the duration time of the starting sequence, the difference between the actual ambient temperature and the set temperature can be reduced, the temperature of the target area is prevented from being too high or too low, and the use reliability of the air conditioner air supply quantity adjusting method is improved. It can be understood that the method of reducing the opening degree of the air valve and/or the number of the opened air valves in the target area and reducing the frequency of the compressor can be used to reduce the air supply amount of the air conditioner, and the method can be specifically adjusted according to different requirements.
In one embodiment, referring to fig. 5, after step S300, step S610 and step S620 are further included.
Step S610: and detecting the adjustment required time consumed for the environment temperature of the target area after the air supply quantity of the air conditioner is reduced to reach the set temperature.
The time for detecting and adjusting the required time is not unique, for example, the required time can be detected and adjusted in real time, and the obtained required time can be continuously compared with the preset starting time sequence time, so that the working accuracy can be improved. Or, the adjustment required time can be detected according to a preset time interval so as to meet the user-defined requirement, and the use is flexible.
Step S620: and when the adjustment required time is greater than or equal to the duration time of the starting sequence, controlling to maintain the air supply quantity of the air conditioner unchanged.
After the air supply amount is reduced, the calculated demand time of the air conditioner when the air conditioner is started can be properly prolonged, the adjustment demand time consumed when the ambient temperature of the target area after the air supply amount of the air conditioner is reduced reaches the set temperature is continuously detected, when the adjustment demand time is still less than the duration time of the starting time sequence, the air supply amount of the air conditioner is continuously reduced until the adjustment demand time is detected to be more than or equal to the duration time of the starting time sequence, the air supply amount of the air conditioner is not changed, the ambient temperature of the target area is prevented from exceeding the set temperature, and the use reliability of the air supply amount adjusting method of the air.
For a better understanding of the above embodiments, the following detailed description is given in conjunction with a specific embodiment. In one embodiment, referring to fig. 6, the air conditioner air supply amount adjusting method includes the following steps: when the unit is started, the required time T1 from the current environment temperature to the temperature set by the user is calculated, in the system, the current environment temperature is obtained from the temperature controller, the set temperature is obtained from the regional control terminal, and data integration and processing are carried out in the regional control terminal. T1 is calculated according to equation (3) in the above embodiment, P is the cooling/heating amount, and taking the heating amount as an example (the cooling condition and the heating condition are the same), the heating amount is determined by the air volume, the specific heat, the average temperature, and the like. The calculation formula is formula (2) in the above embodiment. Then, the sizes of the cooling/heating demand time (T1) and the unit startup sequence duration (T2) are judged in real time, and the size of T2 can be obtained from the regional control terminal, assuming that the size of T2 is 6 minutes. There are the following situations:
if the calculated T1 is 4 minutes, only one air valve is opened at this time, which indicates that the current ambient temperature can reach the set temperature after the unit is opened for 4 minutes, and at this time, the current ambient temperature does not satisfy 6 minutes (T2), and the unit cannot be stopped at the time of starting up, so the air valve cannot be closed, which causes the temperature to be too high/too low, in this case, the opening of the air valve needs to be adjusted before 4 minutes, and the heating/cooling amount is reduced, so that the T1 is increased until the T2 is equal.
