When the air conditioner works, the air conditioner operates according to target parameters and adjusts the room temperature, the room humidity and the like, so that the room environment meets the comfort requirement.
As for the parameter value of the target parameter of the air conditioner, one condition is a system recommended parameter value placed in the air conditioner, or a parameter value calculated according to the system recommended parameter value; another case is a parameter value set by the user or a parameter value calculated from a parameter value set by the user. For the first case, if the parameter value is the system recommended parameter value or a parameter value calculated from the system recommended parameter value, the system recommended parameter value is generally a suitable value in the experimental environment under the standard condition. However, when the air conditioner is actually used, the conditions change, and almost all conditions are not standard conditions, so the system recommended parameter value is not necessarily an appropriate value, and the room environment comfort obtained based on the system recommended parameter value is poor. For the second case, if the parameter value is set by the user or calculated according to the user setting, since the user generally does not know the performance of the air conditioner and the matched using environment, the room environment comfort is poor due to the fact that different air conditioners in the environment condition cannot reach the target parameter; or the air conditioner cannot more reasonably reach the target parameters, resulting in deterioration of the operation performance of the air conditioner.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to fig. 1, a flow chart of an embodiment of a heating operation control method of an air conditioner according to the present invention is shown.
As shown in fig. 1, the method for implementing the heating operation control of the air conditioner of the embodiment includes the following steps:
step 11: and acquiring the actual heating capacity of the air conditioner in operation in a set time period and the actual temperature change of the room in which the air conditioner is positioned in the set time period.
The set time period is a predetermined time value, for example, 1 hour. The actual heating amount refers to the sum of the heat provided by the room where the air conditioner is located in a set time period when the air conditioner is in heating operation. The actual heating capacity reflects the heating operation capacity of the air conditioner in the current environment. Please refer to the flowchart of fig. 2 and the following detailed description of fig. 2 for a method for acquiring the actual heating capacity.
Meanwhile, the actual temperature change of the room where the air conditioner is located in the set time period is obtained, and the actual temperature change reflects the comfort of the room where the air conditioner is located under the running condition of the air conditioner. Wherein the actual temperature change includes, but is not limited to, an actual temperature increase value or an actual temperature increase rate. For example, when heating operation is performed, the actual temperature change is an actual temperature increase value, which is an increase value of the room temperature in the set time period, and the room temperature at the beginning of the set time period and the room temperature at the end of the set time period are obtained, and then the difference between the room temperature at the end of the set time period and the room temperature at the beginning of the set time period is calculated, and the obtained difference is the increase value of the room temperature, that is, the actual temperature change.
Step 12: and determining the reference temperature change corresponding to the actual heating quantity.
Specifically, the reference temperature change corresponding to the actual heating amount is determined according to the actual heating amount obtained in step 11 and the known correspondence relationship between the heating amount and the reference temperature change.
The corresponding relation between the heating quantity and the reference temperature change is stored in advance and can be conveniently read by a controller of the air conditioner. Preferably, the correspondence between the heating amount and the reference temperature variation is obtained through experiments and stored in a controller of the air conditioner in a table form, or stored in a cloud server. And when the experiment is obtained, the air conditioner is placed in a standard room with standard values of room area, room height, room heat dissipation coefficient and the like, the air conditioner is controlled to continuously operate for a certain time, the sum of the heating capacity in the time and the room temperature change corresponding to the time are obtained, the room temperature change is used as the reference temperature change corresponding to the heating capacity, the corresponding relation between the heating capacity and the reference temperature change is formed, and the corresponding relation is stored in the table. And sequentially acquiring the corresponding relations of the reference temperature changes of the plurality of heating cores in different time periods, wherein all the corresponding relations form a complete table for storage. Then, after the actual heating amount is obtained in step 11, a heating amount that is the same as or closest to the actual heating amount in the table is looked up, and the reference temperature change corresponding to the heating amount is determined as the reference temperature change corresponding to the actual heating amount. Or, the reference temperature change corresponding to the actual heating amount may be determined by looking up two heating amounts adjacent to each other before and after the actual heating amount in the table and the reference temperature change corresponding to the two heating amounts according to a linear interpolation method, an averaging method, or another method.
Step 13: and determining a target parameter according to the comparison result of the actual temperature change and the reference temperature change corresponding to the actual heating capacity, and controlling the air conditioner to operate according to the target parameter.
The target parameters are all target parameters that the air conditioner may have when operating, including but not limited to target temperature, target frequency, target capacity operating parameters, etc.
The method is adopted to control the heating operation of the air conditioner, so that the target parameter of the operation of the air conditioner is dynamically adjusted according to the actual heating quantity and the actual temperature change of the room during the operation of the air conditioner, and the actual heating quantity and the actual temperature change of the room reflect the operation capacity of the air conditioner and the real-time temperature condition representing the room comfort in real time, so that the target parameter determined based on the actual heating quantity and the actual temperature change of the room better accords with the operation capacity and the room comfort of the air conditioner, and the room comfort is improved and the operation performance of the air conditioner can also be improved when the target parameter is used for controlling the operation of the air conditioner. More specifically, the determination of the target parameter and the resulting technical effect are detailed as follows:
step 13 determines target parameters including a target temperature, i.e. a temperature which is desired to be reached by the room. If the actual temperature change is the actual temperature increase value or the actual temperature increase rate when the air conditioner is in heating operation, and the corresponding relationship between the heating capacity and the reference temperature change is the corresponding relationship between the heating capacity and the reference temperature increase value or the reference temperature increase rate, the target temperature is determined according to the comparison result of the actual temperature change and the reference temperature change corresponding to the actual heating capacity, which specifically comprises the following steps:
and (3) during the heating operation of the air conditioner, comparing the actual temperature change with the reference temperature change corresponding to the actual heating quantity, and specifically calculating the ratio of the actual temperature change to the reference temperature change. Then, the target temperature is determined according to the magnitude relation between the ratio and the threshold value.
And if the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is greater than a first threshold value, reducing the target temperature, and determining the reduced target temperature as a target parameter. The target temperature is decreased, which means that the target temperature is decreased based on the current target temperature. Wherein the first threshold is a known value greater than 1. As a preferred embodiment, the first threshold is 1.2. If the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is greater than the first threshold value, that is, greater than 1, it indicates that the actual temperature change is greater than the reference temperature change corresponding to the actual heating capacity. In this case, it is determined that the temperature in the room is excessively rapidly increased during heating, and the excessively rapid temperature increase is likely to affect the comfort of the room due to the temperature-reaching shutdown. Therefore, in this case, the target temperature is reduced so that the difference between the target temperature and the room temperature becomes small, and then, when the temperature adjustment control is performed based on the difference between the target temperature and the room temperature, the indoor temperature increase speed can be slowed down, and the room discomfort caused by too fast temperature increase can be avoided. Meanwhile, due to the fact that the target temperature is reduced, the operation energy consumption, the heating capacity and the operation noise of the air conditioner can be reduced, and the operation performance of the air conditioner is improved.
And if the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is smaller than a second threshold value, increasing the target temperature, and determining the increased target temperature as the target parameter. The target temperature is increased based on the current target temperature. Wherein the second threshold is a known value less than 1. As a preferred embodiment, the second threshold is 0.8. If the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is smaller than the second threshold, that is, smaller than 1, it indicates that the actual temperature change is smaller than the reference temperature change corresponding to the actual heating capacity. Under the condition, the temperature in the room is determined to be heated too slowly in the heating process, and the room temperature cannot reach the required comfort temperature as soon as possible due to the too-slow heating process, so that the room comfort is influenced. Therefore, in this case, the target temperature is raised so that the difference between the target temperature and the room temperature becomes large, and then, when the temperature adjustment control is performed based on the difference between the target temperature and the room temperature, the indoor temperature raising speed can be increased, thereby avoiding the room discomfort caused by too slow temperature raising.
In other preferred embodiments, the heating minimum target temperature and the heating maximum target temperature are preset. When the air conditioner is in heating operation, if the reduced target temperature is less than the minimum heating target temperature, determining the minimum heating target temperature as a target parameter; and if the increased target temperature is greater than the maximum heating target temperature, determining the maximum heating target temperature as a target parameter.
In some other more preferred embodiments, the following process is further included:
when the air conditioner is in heating operation, if the reduced target temperature is less than the minimum heating target temperature, a prompt that the room area is too small is sent; and if the raised target temperature is higher than the maximum heating target temperature, sending a prompt of overlarge room area. If the reduced target temperature is less than the heating minimum target temperature, which indicates that the heating speed is faster under the condition that the target temperature is less than the heating minimum target temperature, at this time, the room area is too small relative to the rated heating capacity of the air conditioner, that is, the air conditioner with too large heating capacity is installed, a prompt that the room area is too small is sent out so as to provide a reference basis for replacing the air conditioner. If the increased target temperature is higher than the maximum heating target temperature, the heating speed is too slow, which is probably because the room area is too large relative to the rated heating capacity of the air conditioner, that is, the air conditioner with too small heating capacity is installed, and the target temperature is difficult or not easy to reach under the current working condition, a prompt that the room area is too large is sent out so as to provide a reference basis for replacing the air conditioner.
In addition, step 13 determines the target parameters, which also includes determining a target frequency, i.e., a target frequency for controlling the operation of the compressor of the air conditioner. If the actual temperature change is the actual temperature increase value or the actual temperature increase rate when the air conditioner is in heating operation, and the corresponding relationship between the heating capacity and the reference temperature change is the corresponding relationship between the heating capacity and the reference temperature increase value or the reference temperature increase rate, then the target frequency is determined according to the comparison result of the actual temperature change and the reference temperature change corresponding to the actual heating capacity, which specifically comprises the following steps:
in the heating operation of the air conditioner, the actual temperature change is compared with the reference temperature change corresponding to the actual heating quantity, and specifically, the ratio of the actual temperature change to the reference temperature change is calculated. Then, the target frequency is determined according to the magnitude relation between the ratio and the threshold value.
And if the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is greater than a third threshold value, reducing the target frequency, and determining the reduced target frequency as the target parameter. The target frequency is reduced based on the current target frequency, which may be a frequency value obtained according to a conventional method. Wherein the third threshold is a known value greater than 1. As a preferred embodiment, the third threshold is 1.2. If the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is greater than the first threshold value, that is, greater than 1, it indicates that the actual temperature change is greater than the reference temperature change corresponding to the actual heating capacity. In this case, it is determined that the temperature in the room is excessively rapidly increased during heating, and the excessively rapid temperature increase is likely to affect the comfort of the room due to the temperature-reaching shutdown. Therefore, in this case, the target frequency is reduced, so that the compressor of the air conditioner operates in a frequency-reducing manner, the indoor temperature rise speed can be reduced, and the discomfort of the room caused by too fast temperature rise can be avoided. Meanwhile, due to the fact that the target frequency is reduced, the operation energy consumption, the heating capacity and the operation noise of the air conditioner can be reduced, and the operation performance of the air conditioner is improved.
And if the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is smaller than a fourth threshold value, increasing the target frequency, and determining the increased target frequency as the target parameter. Raising the target frequency means raising on the basis of the current target frequency. Wherein the fourth threshold is a known value less than 1. As a preferred embodiment, the fourth threshold is 0.8. If the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is smaller than the fourth threshold, that is, smaller than 1, it indicates that the actual temperature change is smaller than the reference temperature change corresponding to the actual heating capacity. Under the condition, the temperature in the room is determined to be heated too slowly in the heating process, and the room temperature cannot reach the required comfort temperature as soon as possible due to the too-slow heating process, so that the room comfort is influenced. Therefore, in this case, the target frequency is increased, so that the air conditioner compressor is operated in an increasing frequency, the indoor temperature rise speed can be increased, and the room discomfort caused by too slow temperature rise can be avoided.
Step 13 determines target parameters, and also includes determining target capacity operating parameters. In order to increase the compatibility of the air conditioner with the use environment, a plurality of sets of capacity operation parameters are preset in some air conditioners, for example, two sets of capacity operation parameters are preset, namely a small capacity operation parameter and a large capacity operation parameter. Different capacity operation parameters correspond to different frequency control strategies, wind speed control strategies, expansion valve opening degree control strategies, different rated heating quantities and the like. If the actual temperature change is the actual temperature increase value or the actual temperature increase rate when the air conditioner is in heating operation, and the corresponding relationship between the heating capacity and the reference temperature change is the corresponding relationship between the heating capacity and the reference temperature increase value or the reference temperature increase rate, then the target capacity operation parameter is determined according to the comparison result of the actual temperature change and the reference temperature change corresponding to the actual heating capacity, and the method specifically comprises the following steps:
and (3) during the heating operation of the air conditioner, comparing the actual temperature change with the reference temperature change corresponding to the actual heating quantity, and specifically calculating the ratio of the actual temperature change to the reference temperature change. And then, determining a target capacity operation parameter according to the magnitude relation between the ratio and the threshold value.
If the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is greater than a fifth threshold, determining the low-capacity operation parameter as a target parameter when the current operation parameter of the air conditioner is a non-low-capacity operation parameter; and when the current operation parameter of the air conditioner is a low-capacity operation parameter, a prompt that the room area is too small is sent. Wherein the fifth threshold is a known value greater than 1. As a preferred embodiment, the fifth threshold is 1.2. If the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is greater than the fifth threshold, that is, greater than 1, it indicates that the actual temperature change is greater than the reference temperature change corresponding to the actual heating capacity. In this case, it is determined that the temperature in the room is excessively rapidly increased during heating, and the excessively rapid temperature increase is likely to affect the comfort of the room due to the temperature-reaching shutdown. Therefore, in this case, the selected low-capacity operation parameter is determined as the target capacity operation parameter, so as to slow down the indoor temperature rise speed and avoid the room discomfort caused by too fast temperature rise. If the current operating parameter is not the low-capacity operating parameter, the low-capacity operating parameter can be directly determined as the target capacity operating parameter. However, if the current operating parameter is a low-capacity operating parameter, which indicates that the temperature rising speed is still faster under the low-capacity operating parameter, the room area is too small relative to the rated heating capacity of the air conditioner, that is, the air conditioner with too large heating capacity is installed, and since the operating parameter cannot be selected any more, a reminder that the room area is too small is sent out, so as to provide a reference basis for replacing the air conditioner.
And if the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is smaller than a sixth threshold, determining the high-capacity operation parameter as a target parameter when the current operation parameter of the air conditioner is a non-high-capacity operation parameter, and sending a prompt of overlarge room area when the current operation parameter of the air conditioner is the high-capacity operation parameter. Wherein the sixth threshold is a known value less than 1. As a preferred embodiment, the sixth threshold is 0.8. If the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating capacity is smaller than the sixth threshold, that is, smaller than 1, it indicates that the actual temperature change is smaller than the reference temperature change corresponding to the actual heating capacity. Under the condition, the temperature in the room is determined to be heated too slowly in the heating process, and the room temperature cannot reach the required comfort temperature as soon as possible due to the too-slow heating process, so that the room comfort is influenced. Therefore, in this case, the selected high-capacity operation parameter is determined as the target capacity operation parameter, so as to accelerate the indoor temperature rise speed and avoid the room discomfort caused by too slow temperature rise. If the current operating parameter is not a high-capacity operating parameter, the high-capacity operating parameter can be directly determined as a target capacity operating parameter. However, if the current operation parameter is a high-capacity operation parameter, which indicates that the heating rate is slower under the high-capacity operation parameter, the room area is too large relative to the rated heating capacity of the air conditioner, that is, the air conditioner with too small heating capacity is installed, and since the operation parameter cannot be selected any more, a warning that the room area is too large is sent out so as to provide a reference basis for replacing the air conditioner.
In the air conditioner control process, the target temperature, the target frequency and the target capacity operation parameter can be determined separately according to the comparison result of the actual temperature change and the reference temperature change corresponding to the actual heating capacity, but the method is not limited to this, and two or three target parameters can be determined simultaneously.
In addition, in some other preferred embodiments, the following control process is also included:
and when the air conditioner is in heating operation, if the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating quantity is smaller than a seventh threshold value, sending a prompt for checking the room airtightness. The seventh threshold is also a known value smaller than 1, and is smaller than the second threshold, the fourth threshold and the sixth threshold, for example, the seventh threshold is 0.4. When the air conditioner is in heating operation, if the ratio of the actual temperature change to the reference temperature change corresponding to the actual heating quantity is smaller than the seventh threshold, the actual temperature rise is very slow, in this case, the room tightness is not good, such as window opening or door opening, a prompt for checking the room tightness is sent out, so as to reduce the discomfort problem caused by too slow temperature rise due to the tightness problem.
Referring to fig. 2, a flow chart for determining the actual heating capacity in fig. 1 is shown.
First, a technical idea of obtaining an actual heating amount will be briefly described:
the heating amount when the air conditioner is operated for heating may be obtained according to the heating energy efficiency ratio and the operation power. Theoretical analysis and experimental verification prove that the factors which have larger influence on the heating energy efficiency ratio during air heating operation are indoor temperature and compressor frequency, and outdoor temperature, indoor machine rotating speed and outdoor machine rotating speed have smaller influence on the heating energy efficiency ratio. Therefore, in order to simplify the on-line detection process of the heating energy efficiency ratio and ensure the detection accuracy, the application proposes that the heating energy efficiency ratio influenced by the real-time indoor temperature and the real-time press frequency is taken as the core energy efficiency ratio and is determined by adopting an experimental data calculation mode; and the energy efficiency ratio of the factor having a small influence on the heating energy efficiency ratio is determined by correcting the energy efficiency ratio according to the real-time value and the rated value. And then, determining the total real-time heating energy efficiency ratio under the influence of all factors. And finally, determining the actual heating quantity based on the real-time heating energy efficiency ratio.
As shown in fig. 2, the method for acquiring the actual heating capacity of the air conditioner in the embodiment includes the following steps:
step 21: in the running process of the air conditioner, the real-time press frequency f, the real-time indoor temperature tn, the real-time outdoor temperature tw, the real-time indoor machine rotating speed nn, the real-time outdoor machine rotating speed nw and the real-time running power P in a set time period are obtained.
Because the compressor, the indoor fan and the outdoor fan are all controlled by the frequency and the wind speed by the instruction sent by the main controller of the air conditioner, the real-time frequency f of the compressor, the real-time rotating speed nn of the indoor unit and the real-time rotating speed nw of the outdoor unit can be conveniently obtained by the main controller of the air conditioner. The real-time indoor temperature and the real-time outdoor temperature can be detected and acquired by temperature detection devices arranged indoors and outdoors, respectively. The real-time operating power P can be obtained by using the prior art, and is not specifically described herein.
Step 22: determining a real-time core energy efficiency ratio COPc corresponding to the real-time press frequency f and the real-time indoor temperature tn, and determining a real-time outdoor temperature energy efficiency ratio correction factor COPTw, a real-time indoor machine rotating speed energy efficiency ratio correction factor COPnn and a real-time outdoor machine rotating speed energy efficiency ratio correction factor COPNw.
Specifically, the real-time core energy efficiency ratio COPc corresponding to the real-time compressor frequency f and the real-time indoor temperature tn is determined according to a known core energy efficiency ratio reference table. The core energy efficiency ratio reference table generally refers to a table which is measured in a laboratory before the air conditioner leaves a factory and is written into a memory of the air conditioner, and a specific example is shown in table 1 below.
TABLE 1 core energy efficiency ratio reference Table
In the core energy efficiency ratio reference table shown in table 1 above, five reference indoor temperatures, 15 ℃, 20 ℃, 25 ℃, 30 ℃ and 35 ℃, respectively, are included, and nine reference press frequencies, 20hz, 30hz, 40hz, 50hz, 60hz, 70hz, 80hz, 90hz, and 100hz, respectively, are included. And forming a table with 9 rows and 5 columns by taking each reference press frequency as a row and each reference indoor temperature as a column, wherein each reference press frequency and each reference indoor temperature respectively correspond to one core energy efficiency ratio reference value, and the total number of 45 core energy efficiency ratio reference values (the core energy efficiency ratio reference values in the table are values amplified by 100 times) form table contents. Taking a core energy efficiency ratio reference value 704 corresponding to a reference indoor temperature of 15 ℃ and a reference press frequency of 20hz as an example, a method for acquiring a core energy efficiency ratio reference table is briefly described as follows:
