[0002] Air conditioners are important home appliances in our lives. In summer or in tropical regions, the variable frequency module of the air conditioner outdoor unit determines whether the compressor works normally and can affect the compressor operating frequency, thereby affecting the air conditioner cooling capacity.

[0054] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described below in connection with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0055] The present application will be described below in connection with Figures 1-4 The present application provides an air conditioner variable frequency module assembly control method, device, equipment and air conditioner. The embodiments provided by the present application increase the rotation speed of the outdoor fan, increase the ventilation of the radiator, realize rapid cooling of the variable frequency module, and improve the operation efficiency of the compressor.

[0056] The present application discloses an air conditioner, comprising a controller and an outdoor unit connected with the controller through an electrical signal, wherein the outdoor unit comprises at least a variable frequency module assembly, an outdoor fan and a compressor, and the variable frequency module assembly comprises at least a variable frequency module, a radiator connected with the variable frequency module and a temperature sensor.

[0057] The temperature sensor is used to collect the temperature of the variable frequency module. The radiator is used to absorb the heat of the variable frequency module.

[0058] As Figure 1 shown, it is one of the implementation flow diagrams of the control method of the air conditioner variable frequency module assembly provided by the embodiments of the present application, and the control method of the air conditioner variable frequency module assembly can include but is not limited to steps S100 to S400.

[0059] S100, collecting the temperature of the variable frequency module;

[0060] S200, determining whether the temperature of the variable frequency module is greater than or equal to a preset temperature threshold;

[0061] S300, in the case where the temperature of the variable frequency module is greater than or equal to the temperature threshold, increasing the initial rotation speed of the outdoor fan to a target rotation speed;

[0062] S400, control the external fan to operate at the target rotating speed.

[0063] It should be noted that the execution subject of the control method of the air conditioner variable frequency module assembly in the embodiments of the present application can be a hardware device with data information processing capability and / or necessary software required to drive the hardware device to work.

[0064] Optionally, the execution subject can include but is not limited to a workstation, a server, a computer, a user terminal and other intelligent devices. The user terminal includes but is not limited to a mobile phone, a computer, a smart voice interactive device, a smart household appliance, a vehicle-mounted terminal and the like.

[0065] In step S100 of some embodiments, the variable frequency module temperature of the variable frequency module is collected.

[0066] It can be understood that first, the outdoor environment temperature of the environment where the outdoor unit is located is collected by using a temperature sensor, the outdoor environment temperature is T1, the temperature threshold is T2, the outdoor environment temperature T1 and the temperature threshold T2 are compared to obtain a temperature comparison result.

[0067] Based on the temperature comparison result, a module temperature collection instruction is generated, and the module temperature collection instruction is issued to the temperature sensor, so that the temperature sensor collects the variable frequency module temperature of the variable frequency module according to the module temperature collection instruction, and the variable frequency module temperature is T3.

[0068] Further, the execution step of generating the module temperature collection instruction based on the temperature comparison result can be:

[0069] In the case where the temperature comparison result indicates that the outdoor environment temperature T1 is greater than or equal to the temperature threshold T2, the module temperature collection instruction is automatically generated, which indicates that the outdoor environment temperature is high, and therefore the variable frequency module temperature of the variable frequency module needs to be collected to adjust the variable frequency module temperature.

[0070] In the case where the temperature comparison result indicates that the outdoor environment temperature T1 is less than the temperature threshold T2, the operating time length of the outdoor unit, i.e. the time length of the operation of the outdoor unit, is obtained, because the outdoor unit also generates heat after operation, to avoid the case where the outdoor environment temperature is not high, but the outdoor unit also generates a large amount of heat, resulting in poor heat dissipation effect of the variable frequency module and affecting the operating efficiency of the compressor.

[0071] Let the compressor operating time length be H1 and the first preset time length be H2.

[0072] The compressor operating time H1 and the first preset time H2 are compared, and in the case where the operating time H1 reaches the first preset time H2, the module temperature acquisition instruction is generated to issue the module temperature acquisition instruction to the temperature sensor, so that the temperature sensor acquires the frequency conversion module temperature of the frequency conversion module according to the module temperature acquisition instruction.

[0073] In step S200 of some embodiments, it is judged whether the frequency conversion module temperature is greater than or equal to a preset temperature threshold.

[0074] It can be understood that after the step of acquiring the frequency conversion module temperature of the frequency conversion module in step S100 is executed, the specific execution step can be: comparing the frequency conversion module temperature T3 and the temperature threshold T2 to determine whether the frequency conversion module temperature T3 is greater than or equal to the temperature threshold T2.

[0075] In step S300 of some embodiments, in the case where it is determined that the frequency conversion module temperature is greater than or equal to the temperature threshold, the initial speed of the external fan is increased to the target speed.

[0076] It can be understood that after the step of judging whether the frequency conversion module temperature is greater than or equal to a preset temperature threshold in step S200 is executed, the specific execution step can be: in the case where it is determined that the frequency conversion module temperature T3 is greater than or equal to the temperature threshold T2, the initial speed of the external fan is increased to the target speed. For example, the initial speed is 50 revolutions per minute, and the target speed to be adjusted is 100 revolutions per minute.

[0077] It should be further pointed out that after the step of judging whether the frequency conversion module temperature is greater than or equal to a preset temperature threshold, the method further comprises:

[0078] In the case where it is determined that the frequency conversion module temperature T3 is less than the temperature threshold T2, the indoor environment temperature and the set temperature are acquired. Let the indoor environment temperature be T4, T4 is 30 degrees Celsius, and the set temperature be T5, T5 is 24 degrees Celsius.

[0079] The indoor environment temperature T4 and the set temperature T5 are calculated to obtain the temperature difference T6, i.e. T6 = |T4-T5|, wherein T6 is the temperature difference, T4 is the indoor environment temperature, and T5 is the set temperature.

[0080] The temperature difference T6 and the preset difference threshold T7 are compared, for example, T7 is 3 degrees Celsius and T6 is 6 degrees Celsius, and the temperature difference T6 is greater than or equal to the preset difference threshold T7.

[0081] In the case that the temperature difference is greater than or equal to a preset difference threshold, the operating frequency of the compressor is increased, such as in a refrigeration mode, and the operating frequency of the compressor is increased to enhance the refrigeration effect.

[0082] In step S400 of some embodiments, the external fan is controlled to operate at the target rotating speed. It can be understood that the external fan operates at the increased target rotating speed, which can improve the ventilation of the radiator, and the greater the ventilation of the radiator, the better the cooling effect of the variable frequency module, so that the variable frequency module is within the normal temperature range, so that the variable frequency module can better drive the compressor to operate, and the operating efficiency of the compressor is improved.

[0083] In some embodiments of the application, the variable frequency module assembly further comprises at least a radiator;

[0084] After the step of controlling the external fan to operate at the target rotating speed, the method further comprises:

[0085] In the case that the external fan operates at the target rotating speed for a second preset time, the inlet temperature and the outlet temperature of the radiator are collected;

[0086] The inlet temperature and the outlet temperature are calculated to obtain a temperature influence factor;

[0087] In the case that the temperature influence factor is less than a preset factor threshold, the external fan is controlled to operate at the initial rotating speed.

[0088] It can be understood that as the external environment temperature decreases, the variable frequency module temperature will also decrease, and then the variable frequency module temperature is too low, which will also affect the operating efficiency of the compressor, so the rotating speed of the external fan is reasonably controlled to make the variable frequency module within the normal temperature range.

[0089] Therefore, in the case that the external fan operates at the target rotating speed for a second preset time, the inlet temperature and the outlet temperature of the radiator are collected, the inlet temperature is T8, and the outlet temperature is T9.

[0090] Further, the step of calculating the inlet temperature and the outlet temperature to obtain the temperature influence factor can be:

[0091] The radiator difference of the inlet temperature and the outlet temperature is calculated, and the radiator sum of the inlet temperature and the outlet temperature is calculated;

[0092] The radiator difference and the radiator sum are calculated to obtain the temperature influence factor.

[0093] Calculate the radiator difference T10 of the inlet temperature T8 and the outlet temperature T9, and calculate the radiator sum T11 of the inlet temperature T8 and the outlet temperature T9.

[0094] T10 = |T8 - T9|, T11 = T8 + T9

[0095] Wherein, T10 is the radiator difference, T11 is the radiator sum, T8 is the inlet temperature, and T9 is the outlet temperature.

[0096] Let the temperature influence factor be K, K = T10 / T11, wherein K is the temperature influence factor, T10 is the radiator difference, and T11 is the radiator sum.

[0097] The calculated temperature influence factor K and the preset factor threshold P are compared and processed, P can be 0.5, in the case that the temperature influence factor K is less than the preset factor threshold P, the outer fan is controlled to operate at the initial speed. That is, the speed of the outer fan is reduced to reduce the noise, and the temperature of the frequency conversion module is prevented from being too low to affect the operating efficiency of the compressor.

[0098] Figure 2 It is the second flowchart of the control method of the air conditioner frequency conversion module assembly provided by the application, the outdoor environment temperature is collected by using an outdoor environment temperature sensor, the outdoor environment temperature and the temperature threshold are compared and processed, when the outdoor environment temperature is greater than or equal to the temperature threshold, the frequency conversion module temperature of the frequency conversion module is collected by using a temperature sensor. And the frequency conversion module temperature and the temperature threshold are compared and processed, when the frequency conversion module temperature is less than the temperature threshold, the operating frequency of the compressor is increased to improve the refrigeration effect of the air conditioner.

[0099] Of course, when the frequency conversion module temperature is greater than or equal to the temperature threshold, the speed of the outer fan is increased to increase the wind speed to cool the frequency conversion module, thereby improving the operating efficiency of the compressor.

[0100] The application provides a kind of air conditioner frequency conversion module assembly control method, device and equipment and air conditioner, a kind of air conditioner frequency conversion module assembly control method, applied to air conditioner, the air conditioner at least includes outdoor unit, the outdoor unit at least includes frequency conversion module assembly and outer fan, the frequency conversion module assembly at least includes frequency conversion module, the air conditioner frequency conversion module assembly control method is by collecting the frequency conversion module temperature of the frequency conversion module;Determine whether the frequency conversion module temperature is greater than or equal to preset temperature threshold;In the case that the frequency conversion module temperature is greater than or equal to the temperature threshold, the initial speed of the outer fan is increased to target speed;The outer fan is controlled to operate at the target speed. By increasing the speed of the outer fan, the ventilation of the radiator is increased, the frequency conversion module is rapidly cooled, and the operating efficiency of the compressor is improved.
