Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

First, briefly describe the technical idea of the present invention:

How to improve the temperature adjustment comfort of the air conditioner and reduce the power consumption of the air conditioner has always been a hot spot and focus in the research of the air conditioner industry. Most of the existing air conditioners are inverter air conditioners. The prior art mostly focuses on the processing of the control algorithm of the air conditioner in terms of improving the comfort and reducing power consumption of the inverter air conditioner, for example, using PID algorithm and fuzzy control algorithm. Regardless of the control algorithm, when the current indoor temperature is used as a parameter, the indoor temperature detected by the indoor temperature sensor installed on the air conditioner is directly used as the current indoor temperature, and then the indoor temperature is used as a reference parameter to execute different control. However, a phenomenon has been overlooked in the prior art, that is, the installation position of the wall-mounted air conditioner is relatively high in the room, and is generally installed at a position about 2 meters away from the ground. The indoor temperature sensor used to detect the indoor temperature on the air conditioner is generally located at the air inlet of the air conditioner or on the evaporator. Therefore, the air temperature detected by the indoor temperature sensor is the temperature of the air at a height of about 2 meters from the ground. In the room, the user's main activity space is generally from the ground to the space area about 1.35 meters above the ground. According to molecular kinetic theory, warm air moves upward and cold air moves downward. Then, when the air conditioner is running in heating mode, because the hot air rises, the temperature of the air above is higher than that of the air below; It is also warmer than the air below. Therefore, the temperature detected by the indoor temperature sensor is slightly higher than the temperature of the user's main activity space. Based on this phenomenon, the present invention proposes an air conditioner control technical scheme that takes into account the comfort of indoor temperature adjustment of the air conditioner and the low power consumption and energy saving performance of the air conditioner from the perspective of the indoor temperature itself.

Please refer to FIG. 1 , which is a flow chart of an embodiment of an air conditioner control method of the present invention, specifically, a method flow of an embodiment of a wall-mounted inverter air conditioner.

As shown in Figure 1, the method for realizing air conditioner control in this embodiment includes the following process steps:

Step 11: Turn on the air conditioner and control the operation of the compressor.

After the air conditioner is turned on, it will control the operation of the compressor according to the user-set or default operation mode and operation parameters, and according to the predetermined control program.

Step 12: Determine whether the running time of the compressor reaches the set running time. If yes, execute the control of step 14; if not, execute the control of step 13.

Among them, the set running time is a time value stored in advance and can be recalled at any time. It is a value obtained by the air conditioner research and development personnel through specific test conditions and specific test methods before the air conditioner leaves the factory and written into the memory of the air conditioner.

A timer is provided in the air conditioner to time the running time of the compressor. When the air conditioner is turned on and the compressor starts to run, the timer starts timing, and when the timing reaches the set running time, it outputs a time signal. During the control process of the air conditioner, different controls will be performed according to whether the running time of the compressor reaches the set running time. Specifically, whether the running time of the compressor reaches the set running time is a necessary condition for determining whether to compensate the indoor temperature.

Step 13: If it is determined in step 12 that the running time of the compressor has not reached the set running time, control the compressor according to a conventional control method.

That is, if the running time of the compressor has not reached the set running time after starting up, the indoor temperature compensation process is not performed, but the compressor is controlled according to a conventional control method. Wherein, the conventional control method refers to the control method of the existing inverter air conditioner. For example, the control method of the existing air conditioner is: when the temperature difference between the indoor temperature and the indoor target temperature is greater than the set temperature difference, the compressor is controlled to run at high frequency until the temperature difference between the indoor temperature and the indoor target temperature is not greater than the set temperature difference. Then, when the running time of the compressor has not reached the set running time, if the compressor needs to run at high frequency in the conventional control method, it will maintain the high-frequency running state, so that the indoor temperature can quickly approach the indoor target temperature, and quickly provide users with A more suitable indoor environment.

In the process of controlling the operation of the compressor according to the conventional control method, the process of judging whether the operation time of the compressor reaches the set operation time is still continuously performed.

Step 14: If it is determined in step 12 that the running time of the compressor has reached the set running time, the indoor temperature will be compensated, and then the target frequency of the compressor will be obtained by using the compensated indoor temperature.

Specifically, after the running time of the compressor after starting up reaches the set running time, the current indoor temperature detected by the indoor temperature sensor is obtained as the first indoor temperature, and the difference between the first indoor temperature and the set compensation temperature is calculated as second room temperature.

Among them, the set compensation temperature is a temperature value stored in advance and can be recalled at any time. It is also a value obtained by the air conditioner research and development personnel through specific test conditions and specific test methods before the air conditioner leaves the factory and written into the air conditioner memory. When the running time of the compressor reaches the set running time, the condition for compensating and controlling the indoor temperature is satisfied, then the current indoor temperature detected by the indoor temperature sensor is obtained, and the current indoor temperature is used as the first indoor temperature. Then, the set compensation temperature is acquired, the difference between the first indoor temperature and the set compensation temperature is calculated, and the difference is used as the second indoor temperature. Then, go to step 15.

Step 15: Calculate the temperature difference between the second indoor temperature and the indoor target temperature to obtain the indoor temperature difference, obtain the compressor target frequency according to the indoor temperature difference, and control the compressor according to the compressor target frequency.

Among them, the process of obtaining the target frequency of the compressor according to the indoor temperature difference between the indoor temperature and the indoor target temperature is a prior art, but different from the prior art, the indoor temperature for calculating the indoor temperature difference is not the temperature detected by the indoor temperature sensor, but is the second indoor temperature obtained after temperature compensation is performed on the detected temperature.

As described above, when the air conditioner operates in cooling mode, the temperature detected by the indoor temperature sensor is higher than the temperature of the user's main activity space. If the temperature detected by the indoor temperature sensor is used as the indoor temperature to obtain the compressor target frequency, for example, the compressor target frequency is obtained through the room temperature PID calculation, then if the detected temperature is used as the indoor temperature to participate in the PID calculation, the indoor temperature difference during the PID calculation Too high, the calculated target frequency of the compressor is too high, and the compressor is controlled to run at the high target frequency, resulting in too much energy consumption of the air conditioner. With the method of this embodiment, the detected indoor temperature is first subtracted by a compensation temperature to obtain a second indoor temperature that is lower than the detected current indoor temperature, and the second indoor temperature more truly reflects the temperature of the user's main activity space . When the relatively small second indoor temperature is used to participate in the PID calculation, a smaller target frequency of the compressor can be obtained, and the operation of the compressor can be controlled by using the smaller target frequency, thereby reducing energy consumption. Moreover, since the second indoor temperature more truly reflects the temperature of the user's main activity space, the adjusted indoor temperature will be closer to the indoor set temperature without the problem of overshooting. While adjusting the comfort, the energy consumption of the air conditioner is reduced.

Similarly, when the air conditioner operates in the heating mode, the temperature detected by the indoor temperature sensor is higher than the temperature of the user's main activity space. If the temperature detected by the indoor temperature sensor is still used as the indoor temperature to participate in the PID calculation, the indoor temperature difference during the PID calculation is relatively small, and the calculated target frequency of the compressor is relatively low. It cannot or needs to run for a long time to reach the indoor target temperature. The comfort of indoor temperature adjustment is poor, and the compressor running at a relatively high target frequency for a long time is not conducive to reducing energy consumption. With the method of this embodiment, the detected indoor temperature is first subtracted by a compensation temperature to obtain a second indoor temperature that is lower than the detected current indoor temperature, and the second indoor temperature more truly reflects the temperature of the user's main activity space . When the relatively small second indoor temperature is used to participate in the PID calculation, a relatively higher compressor target frequency can be obtained, and the indoor temperature can quickly reach the indoor target temperature, thereby improving the comfort of indoor temperature adjustment. Moreover, since the time to reach the indoor target temperature is shortened, it is beneficial to reduce energy consumption.

Moreover, in the whole control process, instead of performing indoor temperature compensation when the compressor starts to run, the compressor is kept running according to the conventional control strategy to ensure that the indoor temperature can quickly approach the indoor target temperature according to the conventional control method. It will not affect the speed of indoor temperature comfort adjustment.

In the above embodiments, when to perform the compensation control of the indoor temperature and how much temperature compensation is performed on the indoor temperature are key factors related to the control comfort and energy saving of the air conditioner. That is to say, the selection of the set running time and the set compensation temperature are the key factors.

As a preferred embodiment, the set running time stored in advance and recalled at any time in the air conditioner is a running time corresponding to the indoor target temperature and the outdoor temperature, and the set compensation temperature stored in advance and recalled at any time is the same as the indoor target temperature. An offset temperature corresponding to the outside temperature. Based on the indoor target temperature and outdoor temperature, the set running time and set compensation temperature can be determined, and the temperature compensation control can be reasonably regulated in terms of compensation time and compensation degree based on the operating load of the air conditioner, achieving temperature comfort adjustment and low energy consumption. gender balance.

Moreover, the air conditioner prestores an indoor target temperature range, an outdoor temperature range, and a plurality of running times and a plurality of compensation temperatures corresponding to the indoor target temperature range and the outdoor temperature range. When the temperature compensation control is executed during the operation of the air conditioner, the set running time and set compensation temperature are respectively called through the following procedures:

The set running time is called by the following method: compare the current indoor target temperature detected by the indoor temperature sensor with the pre-stored indoor target temperature range, and determine the indoor target temperature range to which the current indoor target temperature belongs; compare the current indoor target temperature detected by the outdoor temperature sensor The outdoor temperature is compared with the pre-stored outdoor temperature range to determine the outdoor temperature range to which the current outdoor temperature belongs; according to the pre-stored multiple running times corresponding to the indoor target temperature range and the outdoor temperature range, the current indoor target temperature is searched. The running time corresponding to the indoor target temperature range and the outdoor temperature range to which the current outdoor temperature belongs is used as the set running time and called;

The set compensation temperature is invoked by the following method: compare the current indoor target temperature with the pre-stored indoor target temperature range to determine the indoor target temperature range to which the current indoor target temperature belongs; compare the current outdoor temperature with the pre-stored outdoor temperature range Compare and judge the outdoor temperature range to which the current outdoor temperature belongs; find the indoor target temperature range and the current outdoor temperature to which the current indoor target temperature belongs according to multiple compensation temperatures stored in advance corresponding to the indoor target temperature range and the outdoor temperature range The compensation temperature corresponding to the outdoor temperature range is used as the set compensation temperature and called.

Of course, in the actual control process, the indoor target temperature range to which the current indoor target temperature belongs and the outdoor temperature range to which the current outdoor temperature belongs only need to be judged once, and then search and call the corresponding set running time and set compensation according to the judgment result. temperature, without the need to determine the range twice, the above description is only for a complete description of the process of calling the set running time and setting the compensation temperature.

The above method determines and invokes the set running time and set compensation temperature in the form of temperature range, the amount of data processing is small, and the control process is simple, which is more conducive to timely and effective control of the air conditioner, improving the speed of temperature comfort adjustment, reducing Operating energy consumption.
