A method for controlling a mobile air conditioner according to a second embodiment of the present invention will be described in detail with reference to fig. 5.

In the embodiment, the control method of the electric control software is upgraded and improved, and the operation of the upper fan and the compressor of the mobile air conditioner is controlled according to the temperature detected by the condenser temperature sensor, so that the high-temperature protection function of the condenser is added, and the condenser temperature sensor not only can play a role in controlling defrosting during heating, but also can play a role in high-temperature protection of the condenser during refrigeration.

Specifically, an environment temperature sensor and a condenser temperature sensor of the mobile air conditioner are used for detecting the indoor environment temperature T1 of the space where the indoor unit is located and the temperature T3 of the middle part of the condenser, and parameters are set for a software program, so that the software program can control the running states of a fan and a compressor according to the indoor environment temperature of the space where the indoor unit is located and the temperature of the middle part of the condenser, and the condenser is protected at high temperature.

The specific operation is shown in fig. 5, and comprises the following steps:

and step S502, starting the air conditioner and controlling the mobile air conditioner to run in a refrigeration mode.

In step S504, after the operation time reaches T0 (i.e., the first preset time), the indoor ambient temperature T1 (i.e., the first temperature value) of the space where the indoor unit is located is detected n times within T1 (i.e., the fourth preset time), and the temperature T3 (i.e., the second temperature value of the condenser middle tube temperature T3) of the condenser middle portion is detected n times.

Specifically, after the cooling operation time of the mobile air conditioner reaches T0, the ambient temperature of the space where the indoor unit is located and the temperature of the middle part of the condenser are respectively detected for n times within the time of T1, so that n T1 and n T3 are obtained.

In step S506, it is determined whether T1 is greater than or equal to T8 (i.e., the first preset temperature) and T3 is greater than or equal to T9 (i.e., the second preset temperature), if yes, step S508 is performed, and if no, step S504 is performed.

Specifically, when the number of n T1 greater than or equal to T8 is greater than or equal to a first preset value (i.e., a fourth preset number), it may be determined that T1 is greater than or equal to T8, although it is also possible to calculate an average value of n T1 and compare the average value with T8, when the average value is greater than or equal to T8, it may be determined that T1 is greater than or equal to T8, when the number of n T3 greater than or equal to T9 is greater than or equal to a second preset value (i.e., a fifth preset number), it may be determined that T3 is greater than or equal to T9, and it is also possible to calculate an average value of n T3 and compare the average value with T9, and when the average value is greater than or equal to T9, it may be determined that T3 is greater than or equal to T9.

And step S508, the rotating speed of the upper fan is adjusted to be low, and the lower gear is operated.

In step S510, the indoor ambient temperature T1 (i.e., the third temperature value) of the space where the indoor unit is located is detected n times within T2 (i.e., the third preset time), and the temperature T3 (i.e., the fourth temperature value of the condenser middle tube temperature T3) of the condenser middle is detected n times.

Specifically, after the upper fan is operated at the low gear for a certain time, which needs to be set according to the operating environment of the air conditioner, the ambient temperature of the space where the indoor unit is located and the temperature of the middle part of the condenser are respectively detected n times within the time T2, so as to obtain n new T1 and n new T3.

In step S512, it is determined whether T1 is greater than or equal to T8 and T3 is greater than or equal to T10 (i.e., the third preset temperature), if yes, step S514 is executed, and if no, step S516 is executed.

Specifically, after the updraft fan speed is reduced, when the number of T8 in n newly acquired T1 is greater than or equal to a third preset value (i.e., a second preset number), it may be determined that T3 is greater than or equal to T8, of course, an average value of n T1 may be calculated and compared with T8, when the average value is greater than or equal to T8, it may be determined that T1 is greater than or equal to T8, when the updraft fan speed is reduced, the number of T10 in n newly acquired T3 is greater than or equal to a fourth preset value (i.e., a third preset number), it may be determined that T3 is greater than or equal to T10, of course, the average value of n T3 may be calculated and compared with T10, and when the average value is greater than or equal to T10, it may be determined that T3 is greater than or equal to T10.

And step S514, controlling the compressor to stop running.

In other embodiments of the present invention, when it is determined that T1 is greater than or equal to T8 and T3 is greater than or equal to T10, the rotation speed of the upper fan may be controlled to be reduced again, and if the desired effect cannot be achieved after the rotation speed of the upper fan is reduced again, the compressor is controlled to stop operating; when the rotating speed of the upper fan can be adjusted and the compressor can be controlled to stop running at the same time, so that the aim of cooling is fulfilled.

And step S516, the rotating speed of the upper fan is restored, and the step S504 is executed in a returning mode.

In step S518, the temperature T3 of the middle portion of the condenser (i.e., the fifth temperature value of the pipe temperature T3 of the middle portion of the condenser) is detected n times within the time T3 (i.e., the second preset time).

Specifically, after controlling the compressor to stop operating for a specific time, which is set according to the operating environment of the air conditioner, the tube temperature in the middle of the condenser is detected n times within the time T3 to obtain n new T3.

In step S520, it is determined whether T3 is less than or equal to T11 (i.e., the fourth predetermined temperature), if not, step S514 is executed, and if so, steps S522 and S516 are executed.

Specifically, when the number of the n T3 retrieved after the compressor is controlled to stop running and smaller than or equal to T11 is greater than or equal to a fifth preset value (i.e., the first preset number), it may be determined that T3 is less than or equal to T11, an average value of the n T3 may be calculated and compared with T11, and when the average value is greater than or equal to T11, it may be determined that T3 is less than or equal to T11.

In step S522, the compressor is controlled to start operation, i.e., to return to the operation state before the stop, and then the process returns to step S516.

It is understood that when T3 is less than or equal to T11, step S522 may be executed first, step S516 may be executed first, and step S522 and step S516 may be executed simultaneously.

Specifically, T0 preferably takes 5 minutes to 10 minutes, T1, T2 and T3 preferably takes 10 seconds to 30 seconds, n preferably takes 30 times to 60 times, T8 preferably takes 35 ℃ to 40 ℃, T9 preferably takes 70 ℃ to 75 ℃, T10 preferably takes 75 ℃ to 80 ℃, and T11 preferably takes 65 ℃ to 70 ℃, and it is understood that the values of T0, T1, T2, T3, n, T8, T9, T10 and T11 are one of preferable examples, and may be set to other values according to actual conditions.
