[0002] Air conditioners have become an important household appliance in our lives. When used for cooling in summer or tropical areas, the inverter module of the air conditioner outdoor unit determines whether the compressor works normally or not, and can also affect the operating frequency of the compressor, thereby affecting the cooling capacity of the air conditioner. Therefore, if the heat dissipation effect of the inverter module is not good, it will not only greatly affect the efficiency of the compressor, but also cause the air conditioning system to shut down, causing accidents and adverse effects.

[0054] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Combine the following Figure 1-Figure 4 The present invention describes a control method, device, equipment and air conditioner for an air conditioner frequency conversion module component. The embodiments provided by the present invention increase the rotation speed of the external fan to increase the ventilation volume of the radiator, thereby achieving rapid cooling of the frequency conversion module and improving the operating efficiency of the compressor.

[0056] The present invention discloses an air conditioner, comprising a controller and an outdoor unit connected to the controller through electrical signals, wherein the outdoor unit at least comprises a frequency conversion module component, an outdoor fan and a compressor, wherein the frequency conversion module component at least comprises a frequency conversion module, and a radiator and a temperature sensor connected to the frequency conversion module.

[0057] The temperature sensor is used to collect the inverter module temperature of the inverter module. The heat sink is used to absorb the heat of the inverter module.

[0058] like Figure 1 As shown, it is one of the implementation flow diagrams of a control method of an air-conditioning frequency conversion module assembly provided by an embodiment of the present invention. A control method of an air-conditioning frequency conversion module assembly may include but is not limited to steps S100 to S400.

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

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

[0061] S300, when it is determined that the temperature of the frequency conversion module is greater than or equal to the temperature threshold, increasing the initial speed of the external fan to a target speed;

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

[0063] It should be noted that the execution subject of the control method of an air-conditioning variable frequency module assembly in the embodiment of the present application may be a hardware device with data information processing capabilities and / or the necessary software required to drive the hardware device to work.

[0064] Optionally, the execution subject may include but is not limited to workstations, servers, computers, user terminals and other intelligent devices. Among them, user terminals include but are not limited to mobile phones, computers, intelligent voice interaction devices, smart home appliances, vehicle-mounted terminals, etc.

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

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

[0067] Based on the temperature comparison result, a module temperature acquisition instruction is generated, and the module temperature acquisition instruction is sent 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, and the frequency conversion module temperature is set to T3.

[0068] Furthermore, the execution step of generating a module temperature acquisition instruction based on the temperature comparison result may specifically be:

[0069] When the temperature comparison result indicates that the outdoor ambient temperature T1 is greater than or equal to the temperature threshold T2, the module temperature collection instruction is automatically generated, indicating that the outdoor ambient temperature is high, and therefore the frequency conversion module temperature of the frequency conversion module needs to be collected to adjust the frequency conversion module temperature.

[0070] When the temperature comparison result indicates that the outdoor ambient temperature T1 is less than the temperature threshold T2, the operating time of the outdoor unit is obtained, that is, the time the outdoor unit is turned on and running. Because the outdoor unit will also generate heat after it is running, it is necessary to avoid the situation where the outdoor ambient temperature is not high, but the outdoor unit also generates a large amount of heat, resulting in poor heat dissipation effect of the frequency conversion module, thereby affecting the operating efficiency of the compressor.

[0071] The compressor operation time is H1, and the first preset time is H2.

[0072] The compressor operation time H1 and the first preset time H2 are compared and processed. When the operation time H1 reaches the first preset time H2, the module temperature acquisition instruction is generated, and the module temperature acquisition instruction is sent 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 determined whether the temperature of the frequency conversion module is greater than or equal to a preset temperature threshold.

[0074] It is understandable that after executing step S100 of collecting the frequency conversion module temperature of the frequency conversion module, the specific execution steps may be: comparing the frequency conversion module temperature T3 with 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, when it is determined that the temperature of the frequency conversion module is greater than or equal to the temperature threshold, the initial rotation speed of the external fan is increased to a target rotation speed.

[0076] It is understandable that after executing step S200 to determine whether the temperature of the frequency conversion module is greater than or equal to the preset temperature threshold, the specific execution steps may be: when it is determined that the temperature T3 of the frequency conversion module 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 is now adjusted to 100 revolutions per minute.

[0077] It should also be noted that, after the step of determining whether the temperature of the frequency conversion module is greater than or equal to a preset temperature threshold, the method further includes:

[0078] When 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 obtained. The indoor environment temperature is set to T4, T4 is 30 degrees Celsius, and the set temperature is set to T5, T5 is 24 degrees Celsius.

[0079] The indoor environment temperature T4 and the set temperature T5 are subjected to a difference calculation process to obtain a temperature difference T6, that is, 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 is compared with the preset difference threshold T7. Taking T7 as 3 degrees Celsius and T6 as 6 degrees Celsius as an example, the temperature difference T6 is greater than or equal to the preset difference threshold T7.

[0081] When the temperature difference is greater than or equal to a preset difference threshold, the operating frequency of the compressor is increased. For example, in a cooling mode, increasing the operating frequency of the compressor can enhance the cooling effect.

[0082] In step S400 of some embodiments, the external fan is controlled to operate at the target speed. It is understandable that the operation of the external fan at an increased target speed can increase the ventilation volume through the radiator. The greater the ventilation volume of the radiator, the better the cooling effect of the frequency conversion module, so that the frequency conversion module is within a normal temperature range, so that the frequency conversion module can better drive the compressor to operate, thereby improving the operating efficiency of the compressor.

[0083] In some embodiments of the present invention, the frequency conversion module assembly further comprises at least: a heat sink;

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

[0085] When the external fan runs at the target speed for a second preset time, collecting the air inlet temperature and the air outlet temperature of the radiator;

[0086] Calculating and processing the air inlet temperature and the air outlet temperature to obtain a temperature influence factor;

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

[0088] It is understandable that as the external ambient temperature decreases, the temperature of the frequency conversion module will also decrease. If the temperature of the frequency conversion module is too low, it will also affect the operating efficiency of the compressor. Therefore, it is necessary to reasonably control the speed of the external fan to keep the frequency conversion module within the normal temperature range.

[0089] Therefore, when the external fan is running at the target speed for the second preset time, the air inlet temperature and the air outlet temperature of the radiator are collected, and the air inlet temperature is set to T8 and the air outlet temperature is set to T9.

[0090] Furthermore, the step of calculating and processing the air inlet temperature and the air outlet temperature to obtain the temperature influence factor may specifically be:

[0091] Calculating a radiator difference between the air inlet temperature and the air outlet temperature, and calculating a radiator sum of the air inlet temperature and the air outlet temperature;

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

[0093] A radiator difference value T10 between the air inlet temperature T8 and the air outlet temperature T9 is calculated, and a radiator sum value T11 between the air inlet temperature T8 and the air outlet temperature T9 is calculated.

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

[0095] Among them, T10 is the radiator difference value, T11 is the radiator sum value, T8 is the air inlet temperature, and T9 is the air outlet temperature.

[0096] Let the temperature influence factor be K, K=T10 / T11, where K is the temperature influence factor, T10 is the heat sink difference, and T11 is the heat sink sum value.

[0097] The calculated temperature influence factor K is compared with the preset factor threshold P, where P can be 0.5. When the temperature influence factor K is less than the preset factor threshold P, the external fan is controlled to operate at the initial speed. That is, the speed of the external fan is reduced to reduce noise and prevent the temperature of the frequency conversion module from being too low, thereby affecting the operating efficiency of the compressor.

[0098] Figure 2 This is the second flow chart of the control method of the air conditioner frequency conversion module assembly provided by the present invention. The outdoor environment temperature is collected by using the outdoor environment temperature sensor, and the outdoor environment temperature is compared with the temperature threshold. 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 the temperature sensor. The frequency conversion module temperature is compared with the temperature threshold. When the frequency conversion module temperature is less than the temperature threshold, the operating frequency of the compressor is increased to improve the cooling effect of the air conditioner.

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

[0100] The present invention provides a control method, device, equipment and air conditioner of an air conditioner frequency conversion module assembly.
