Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
At present, commercial and home frequency conversion air conditioners and the like generally adopt the change of the temperature of an indoor coil pipe to judge the load used by the air conditioner and feed the load back to an external unit to control the output of a compressor so as to achieve the aim of adjusting the room temperature. However, the position of the indoor coil temperature sensor in the air conditioner control method, the failure of the indoor coil temperature sensor, the amount of refrigerant in the system and the like often cause inaccurate temperature detection of the indoor coil, and the comfort of the system is greatly reduced. Therefore, it is very important how to accurately and precisely detect the temperature and effectively control the air conditioning system.
The air conditioner control method provided by the embodiment can improve the indoor comfort when the variable frequency air conditioner is used, avoid inaccurate detection caused by poor position, drift distortion or difference of refrigerant quantity of the coil pipe temperature sensor, and can meet the actual requirements of users.
This embodiment is through comparing indoor coil pipe temperature and indoor air-out temperature, confirms that the load to the air conditioner is controlled through which temperature, and then realizes improving the travelling comfort. It is worth noting that when two temperatures are selected, whether the system is abnormal or not can be judged, and the signals can be fed back through an external device so as to be convenient for after-sale maintenance.
Referring to fig. 1, the present embodiment provides an air conditioner control method, which includes:
s1: obtaining indoor coil pipe temperature Tem and indoor air outlet temperature Te 1;
s2: judging the relation between the indoor coil temperature Tem and the indoor air outlet temperature Te 1;
s3: according to the relationship, one of the indoor coil temperature Tem and the indoor outlet air temperature Te1 is selected to control the load of the air conditioner.
The indoor coil temperature Tem is detected by a first temperature sensor 11 (shown in fig. 2, i.e., an indoor coil temperature sensor) installed near the indoor coil, and the indoor outlet air temperature Te1 is detected by a second temperature sensor 12 (shown in fig. 2, i.e., an indoor outlet air temperature sensor) installed near the indoor outlet. The two temperatures are compared to obtain the relationship between the two temperatures, and then one temperature is selected according to the relationship between the two temperatures to control the load of the air conditioner. In this way, if it is known that the indoor coil temperature Tem is accurate from the relationship between the two, the load control of the air conditioner is performed in accordance with the indoor coil temperature Tem. If the indoor coil temperature Tem is not accurately known from the relationship between the indoor coil temperature Tem and the indoor air outlet temperature Te1, the load control of the air conditioner is performed. By the mode, the temperature detection accuracy can be effectively improved, and the comfort is improved.
It should be noted that the load control of the air conditioner mentioned above may include control of the frequency of the compressor and control of the opening degree of the expansion valve. For example, the manner of control may be: the frequency of the compressor is increased and the opening degree of the expansion valve is decreased. The control mode can also be as follows: the frequency of the compressor is reduced and the opening degree of the expansion valve is increased. The control mode can also be as follows: the current operating state, i.e., the frequency of the compressor and the opening degree of the expansion valve, is maintained as it is.
Specifically, the step of selecting one of the indoor coil temperature Tem and the indoor outlet air temperature Te1 to control the load of the air conditioner according to the relationship includes:
case 1: if Te1-a is not less than Tem and not more than Te1, selecting the indoor coil temperature Tem to control the load of the air conditioner;
case 2: if Tem is more than Te1, selecting indoor air outlet temperature Te1 to control the load of the air conditioner;
case 3: if the Tem is less than Te1-a, selecting indoor air outlet temperature Te1 to control the load of the air conditioner;
wherein a is a preset value.

Generally, Tem is 0-3 ℃ lower than Te1, namely a is more than or equal to 0 ℃ and less than or equal to 3 ℃ due to the air conditioning system, the installation positions of two temperature sensors and the like. Thus, in one embodiment, a may be selected to be 3 ℃. Of course, the value of a may be set according to actual conditions for different air conditioners, different temperature sensors, different installation positions, and the like.
According to three different conditions, the load of the air conditioner can be effectively controlled, and the overall comfort is improved. For example, one implementation is as follows:
when the case 1 is established, that is, the condition Te1-a < Tem < Te1 is satisfied, the current operating state, that is, the frequency of the compressor and the opening degree of the expansion valve are maintained as they are.
When case 2 is established, that is, when condition Tem > Te1 is satisfied, the frequency of the compressor is increased and the opening degree of the expansion valve is decreased.
When case 3 is established, that is, when condition Tem < Te1-a is satisfied, the frequency of the compressor is reduced and the opening degree of the expansion valve is increased.
In this embodiment, the air conditioner control method further includes:
and outputting an electrical signal representing the relationship according to the relationship.
Correspond different circumstances through different relations, promptly, can show through the relation of two temperatures, through external equipment to the user can learn the condition of air conditioner directly perceivedly, promptly: whether the detection of the first temperature sensor 11 is abnormal or not can be known, or whether the position of the first temperature sensor 11 is not good or whether the amount of the refrigerant is too much can be known.
In this embodiment, the step of outputting the electrical signal representing the relationship according to the relationship includes:
case 1: if Te1-a is more than or equal to Tem and less than or equal to Te1, outputting a first electric signal;
case 2: if Tem is more than Te1, outputting a second electric signal;
case 3: if Tem is less than Te1-a, outputting a third electric signal;
wherein a is a preset value.
In this embodiment, the three mentioned situations are shown through different electric signals, so that a user can conveniently and accurately know the condition of the air conditioner, and the maintenance is facilitated. For example:
when the case 1 is established, that is, the condition Te1-a is satisfied, that is, the condition Te1-a is not more than Tem not more than Te1 is satisfied, it is determined that there is no abnormality in the detection of the entire air conditioning system and the first temperature sensor 11.
When case 2 is established, that is, when the condition Tem > Te1 is satisfied, it is considered that the first temperature sensor 11 is distorted and the detection result is misaligned.
When the condition 3 is satisfied, that is, when the condition Tem < Te1-a is satisfied, it is considered that the position of the first temperature sensor 11 is not good or the system refrigerant is excessive.
In this embodiment, if the relationship Te1-a ≦ Tem ≦ Te1 holds, the step of determining the relationship between the indoor coil temperature Tem and the indoor outlet air temperature Te1 is repeatedly performed.
When the case 1 is satisfied, the above determination step is repeatedly executed so that the condition can be dealt with in time when the condition is changed, and the timeliness of the detection control is improved.
