S1: Obtain the current temperature and temperature change trend of the heat dissipating component under the operating conditions of the air conditioner;

In step S1, in the case that the suction type air conditioner is operating and heating conditions, the controller can obtain the current temperature of the heat dissipation member 131 through the heat dissipation temperature sensor, based on the heat dissipation member 131 obtained multiple times. The controller can determine the temperature change trend of the heat dissipation member 131. It should be noted that the heating conditions described in the present invention are not limited to the case where the suction type air conditioner executes the heating mode, but may also include the case where the suction type air conditioner executes the indoor defrosting mode, etc. That is, as long as the indoor heat exchanger 11 is used as a condenser, it belongs to the heating operating condition described in the present invention.

These changes do not deviate from the basic principle of the present invention and belong to the protection scope of the present invention.

Next, refer to FIG. 3, which is a flowchart of the steps of a preferred embodiment of the control method of the present invention. As shown in Figure 3, based on the suction air conditioner described in the above preferred embodiment, the preferred embodiment of the control method of the present invention specifically includes the following steps:

S101: Obtain the current temperature and temperature change trend of the heat dissipating component under the operating and heating conditions of the air conditioner;

S102: Determine whether the current temperature is less than the first preset temperature; if yes, execute step S104; if not, execute step S103;

S103: According to the temperature change trend of the heat dissipation component, selectively control the shutdown of the air conditioner;

S104: Selectively adjust the speed of the indoor fan and/or the frequency of the inverter compressor according to the current temperature and temperature change trend of the heat dissipation component.

In step S101, in the case of the air suction type air conditioner operating and heating conditions, the controller can obtain the current temperature of the heat dissipation member 131 through the heat dissipation temperature sensor, based on the heat dissipation member 131 obtained multiple times. The controller can determine the temperature change trend of the heat dissipation member 131. It should be noted that the present invention does not impose any limitation on the manner in which the controller obtains the temperature change trend of the heat dissipation member 131, and the technician can set it according to actual usage requirements; for example, the difference between two adjacent current temperatures can be determined. To make a judgment, it can also be judged by the slope of a graph drawn by multiple current temperatures.

In step S102, the controller can firstly divide and adjust the operation status of the suction type air conditioner according to the comparison result of the current temperature of the heat dissipation member 131 and the first preset temperature, so as 131’s current heating conditions are used to select different adjustment methods, so as to ensure that the heat dissipation member 131 does not have excessive temperature and damage the electronic control module. Thermal effect. It should be noted that the present invention does not impose any restriction on the specific value of the first preset temperature, and the technician can comprehensively consider the specific structure of the electric control box 13 and the high temperature resistance capability of the electric control module to set it by himself; Ground, the first preset temperature is set to 95° C., so as to protect the electronic control module set in the electric control box 13 from high temperature damage to the greatest extent.

Based on the determination result of step S102, if the controller determines that the current temperature of the heat dissipation member 131 is greater than or equal to the first preset temperature, it indicates that the temperature of the heat dissipation member 131 at this time is already high. In this case, the The controller selectively controls the suction type air conditioner to stop according to the temperature change trend of the heat dissipation member 131, so as to effectively ensure that the electronic control module provided in the electric control box 13 is not damaged by high temperature. And if the controller determines that the current temperature of the heat dissipation member 131 is less than the first preset temperature, it means that the temperature of the heat dissipation member 131 at this time is not very high. In this case, the controller only needs to follow the heat dissipation member 131 The current temperature and the temperature change trend can selectively adjust the rotational speed of the indoor fan 12 and/or the frequency of the inverter compressor, so as to protect the electronic control module from high temperature damage while ensuring the suction to the greatest extent. Heating effect of air conditioner.

In the case that the current temperature of the heat dissipation member 131 is greater than or equal to the first preset temperature, the control methods for selectively controlling the shutdown of the suction air conditioner according to the temperature change trend of the heat dissipation member 131 include the following two:

If the temperature of the heat dissipating member 131 shows a non-decreasing trend, that is, it shows a rising trend or a constant trend, the temperature of the heat dissipating member 131 will soon become higher. Such a high temperature can easily affect the electric power installed in the electric control box 13. The control module is damaged, which affects the operation of the entire air conditioner; in this case, the controller controls the suction air conditioner to stop, thereby effectively preventing the temperature of the heat dissipation member 131 from further increasing, thereby effectively protecting the electronic control module Security.

If the temperature of the heat dissipating member 131 shows a downward trend, the temperature of the heat dissipating member 131 may also be automatically lowered. Therefore, the controller does not control the shutdown of the suction type air conditioner, so as to effectively ensure its heating effect to meet the user's needs. Heat demand. At the same time, in order to effectively protect the safety of the electronic control module, the controller needs to control the speed of the indoor fan 12 and the frequency of the inverter compressor not to increase; specifically, when other control logic needs to control the speed of the indoor fan 12 or When the frequency of the inverter compressor increases, the controller will not issue an increase command, so as to effectively control the speed of the indoor fan 12 and the frequency of the inverter compressor no longer increase. Of course, the indoor fan 12 is controlled. The control logic for reducing the speed of the inverter and the frequency of the inverter compressor can be executed normally.

In the case that the current temperature of the heat dissipation member 131 is less than the first preset temperature, the rotation speed of the indoor fan 12 and/or the frequency of the inverter compressor is selectively adjusted according to the current temperature and the temperature change trend of the heat dissipation member 131 Control methods include:

When the current temperature of the heat dissipation member 131 is less than the first preset temperature and greater than or equal to the second preset temperature, it indicates that the temperature of the heat dissipation member 131 is still in a higher temperature range. At this time, the controller Corresponding measures need to be taken to control the temperature of the heat dissipation member 131 not to continue to rise. It should be noted that the present invention does not impose any limitation on the value of the second preset temperature, and technicians can set it according to actual use requirements, as long as the second preset temperature is less than the first preset temperature. Yes; Preferably, the second preset temperature is set to 80°C.

In the above temperature range, if the controller determines that the temperature of the heat dissipating member 131 is increasing, the rotation speed of the indoor fan 12 is controlled to decrease and the frequency of controlling the inverter compressor is decreased, so that the temperature of the heat dissipating member 131 can be reduced. Under timely control, it will not rise rapidly to a very high level. Of course, the present invention does not specifically limit the amount of reduction in the rotation speed and the amount of reduction in the frequency, and the technician can set it by himself according to the actual situation. As a preferred adjustment amount, for the extremely regulated indoor fan 12, the speed of the indoor fan 12 is controlled to decrease by one gear, and the frequency of the inverter compressor is controlled to decrease by 10 Hz, so as to better ensure the suction type The heating effect of the air conditioner. However, if the controller determines that the temperature of the heat dissipation member 131 is in a constant trend, both the rotation speed of the indoor fan 12 and the frequency of the inverter compressor must not increase, so as to effectively maintain the trend that the temperature no longer increases. In addition, if the controller determines that the temperature of the heat dissipating member 131 is in a downward trend, the speed of the fan 12 in the control room increases, and the frequency of the inverter compressor can be adjusted freely according to the control results of other control logic, thereby effectively ensuring that the The heating effect of the suction air conditioner is described.

When the current temperature of the heat dissipation member 131 is less than the second preset temperature and greater than or equal to the third preset temperature, it indicates that the temperature of the heat dissipation member 131 is still within the normal temperature range. At this time, the controller is based on Selective measures can be taken for the temperature change trend. It should be noted that the present invention does not impose any restriction on the value of the third preset temperature, and technicians can set it according to actual use requirements, as long as the third preset temperature is less than the second preset temperature. Yes; Preferably, the third preset temperature is set to 70°C.

In the above temperature range, if the controller determines that the temperature of the heat dissipating member 131 is on the rise, it is sufficient to control the speed of the indoor fan 12 and the frequency of the inverter compressor not to increase, so as to effectively prevent the heat dissipating member 131 The temperature rises rapidly, thereby effectively protecting the safety of the electronic control module. If the controller determines that the temperature of the heat dissipation member 131 is in a constant trend, the rotation speed of the fan 12 in the control room increases, and the frequency of the inverter compressor can be adjusted freely according to the control results of other control logic, thereby effectively ensuring that the The heating effect of the suction air conditioner is described; of course, the present invention does not specifically limit the reduction of the rotation speed, and the technician can set it according to the actual situation. Preferably, for the extremely regulated indoor fan 12, the indoor fan is controlled The speed of 12 is reduced by one gear. In addition, if the temperature of the heat dissipating member 131 shows a downward trend, it means that the heat dissipating member 131 has not yet faced the risk of excessive temperature at this time. In this case, the rotation speed of the indoor fan 12 and the frequency of the inverter compressor can be based on other factors. The control result of the control logic is freely adjusted, so as to effectively ensure the normal operation of the suction air conditioner.

In addition, it should be noted that when the current temperature of the heat dissipation member 131 is less than the third preset temperature, the temperature of the heat dissipation member 131 is still in a lower range, and the controller is free to adjust according to the control results of other control logics. The speed of the indoor fan 12 and the frequency of the inverter compressor are sufficient, so as to effectively ensure the heat exchange effect of the suction air conditioner, thereby effectively improving the user experience.

So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the drawings. However, those skilled in the art will readily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
