Description

[0001] The present invention relates to the technical field of air conditioning, and in particular to a control method, device, equipment, storage medium and a motorhome for a motorhome air conditioner. Background Art

[0002] RVs are also usually equipped with air conditioners, but compared to traditional rooms, the air conditioners in RVs are used in different environments, so traditional air conditioning control solutions are no longer applicable.

[0003] For example, in summer, the temperature inside the RV cabin is often higher than the temperature outside the cabin. If the compressor frequency is limited according to the temperature outside the cabin, the cooling or heating effect will be poor. And the temperature at the top of the cabin is higher than the user's body temperature at the bottom, which will cause the air conditioner to fail to start and stop normally.

[0004] If the measure of limiting the compressor frequency by the ambient temperature outside the vehicle is cancelled, the air-conditioning compressor will start running at a high frequency when the outdoor temperature is high, resulting in excessive current, which will affect the life of the compressor.

[0046] 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.

[0047] Combine the following Figure 1-Figure 3 The present invention describes a control method, device, equipment, storage medium and RV of a motorhome air conditioner, which can achieve quietness and energy saving of the RV air conditioner by controlling the compressor frequency of the RV air conditioner.

[0048] like Figure 1 As shown, it is a schematic diagram of an implementation flow of a control method for a motorhome air conditioner provided by an embodiment of the present invention. A control method for a motorhome air conditioner may include but is not limited to steps S100 to S400.

[0049] S100, obtaining the set temperature of the air conditioner and detecting the temperature inside the cabin of the RV;

[0050] S200, calculating the set temperature and the temperature in the vehicle compartment to obtain a temperature difference;

[0051] S300, comparing the temperature difference with a preset temperature threshold, and sending the compressor frequency generated in the indoor unit to the outdoor unit when the temperature difference is greater than or equal to the temperature threshold;

[0052] S400: determining a target frequency of the compressor based on the compressor frequency received by the outdoor unit and a limited frequency of the outdoor unit, and controlling the compressor to operate at the target frequency.

[0053] It should be noted that the executor of the control method of a motorhome air conditioner in an 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.

[0054] 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.

[0055] In step S100 of some embodiments, the set temperature of the air conditioner is obtained, and the temperature inside the cabin of the RV is detected.

[0056] It is understandable that the controller obtains the set temperature set by the user for the air conditioner, and sets the set temperature to T1. The temperature sensor in the compartment detects the temperature in the compartment of the RV to obtain the temperature in the compartment, and sets the temperature in the compartment to T2.

[0057] In step S200 of some embodiments, the set temperature and the temperature in the vehicle compartment are calculated to obtain a temperature difference.

[0058] It can be understood that after executing step S100 to obtain the set temperature of the air conditioner and detect the temperature inside the cabin of the RV, the specific execution steps may be: calculating the set temperature T1 and the cabin temperature T2 to obtain the temperature difference, and setting the temperature difference to T3.

[0059] T3 = |T1-T2|, where T3 is the temperature difference, T1 is the set temperature, and T2 is the temperature inside the vehicle.

[0060] In step S300 of some embodiments, the temperature difference is compared with a preset temperature threshold, and when the temperature difference is greater than or equal to the temperature threshold, the compressor frequency generated in the indoor unit is sent to the outdoor unit, and the outdoor unit at least includes a compressor.

[0061] It is understandable that after executing step S200 of calculating the set temperature and the temperature in the vehicle compartment to obtain the temperature difference, the specific execution steps may be:

[0062] The temperature difference T3 is compared with the preset temperature threshold T4. Taking the temperature threshold T4 as 6 degrees Celsius as an example, when the temperature difference T3 is greater than or equal to T4, the compressor frequency P1 is sent from the indoor unit to the outdoor unit.

[0063] In step S400 of some embodiments, a target frequency of the compressor is determined based on the compressor frequency received by the outdoor unit and a limited frequency of the outdoor unit, and the compressor is controlled to operate at the target frequency.

[0064] It can be understood that after executing step S300 of comparing the temperature difference with the preset temperature threshold, and sending the compressor frequency generated by the indoor unit to the outdoor unit when the temperature difference is greater than or equal to the temperature threshold, the specific execution steps may be: comparing the compressor frequency received by the outdoor unit with the limited frequency of the outdoor unit to obtain a frequency comparison result;

[0065] The target frequency of the compressor is determined according to the frequency comparison result.

[0066] Furthermore, the limited frequency of the outdoor unit is set to P3.

[0067] The compressor frequency P1 received by the outdoor unit is compared with the limited frequency P3 to obtain a frequency comparison result.

[0068] When the frequency comparison result indicates that the compressor frequency P1 is greater than or equal to the limited frequency P3, the compressor frequency P1 is used as the target frequency of the compressor;

[0069] When the frequency comparison result indicates that the compressor frequency P1 is less than the limited frequency P3, the limited frequency P3 is used as the target frequency of the compressor.

[0070] This can more accurately control the compressor to run at the target frequency, achieving energy and power saving.

[0071] In some embodiments of the present invention, after the steps of obtaining the set temperature of the air conditioner and detecting the temperature inside the cabin of the RV, the method includes:

[0072] Comparing the set temperature T1 with the cabin temperature T3;

[0073] When the set temperature T1 and the cabin temperature T3 are the same, determining the operation mode of the air conditioner;

[0074] When it is determined that the operation mode is the cooling mode and the set temperature is the same as the temperature in the vehicle compartment, the compressor and the external fan are controlled to stop running, and the set temperature and the compensation threshold are calculated and processed to obtain a first compensation temperature;

[0075] The cabin temperature is compared with the first compensation temperature, and when the cabin temperature is greater than the first compensation temperature, the compressor and the external fan are controlled to operate.

[0076] It should be noted that when the set temperature is different from the temperature inside the car, the compressor and the external fan continue to be controlled to operate normally.

[0077] It is understandable that when it is determined that the operation mode of the air conditioner is the cooling mode, the compressor and the external fan are controlled to stop running, and the internal fan operates normally. Let the compensation threshold be T5, and T5 is 0.5 degrees Celsius.

[0078] The set temperature T1 and the compensation threshold T5 are processed and calculated to obtain the first compensation temperature T6.

[0079] T6=T1+T5

[0080] Wherein, T6 is the first compensation temperature, T1 is the set temperature, and T5 is the compensation threshold.

[0081] The cabin temperature T3 is compared with the first compensation temperature T6. If the cabin temperature T3 is greater than or equal to the first compensation temperature T6, the compressor and the external fan are controlled to operate, which can reduce power consumption and noise generated by the operation of the air-conditioning compressor.

[0082] In some embodiments of the present invention, after the step of determining the operating mode of the air conditioner, the method further includes:

[0083] When it is determined that the operation mode is the heating mode and the set temperature is the same as the temperature in the vehicle compartment, the compressor, the external fan and the internal fan are controlled to stop running, and a difference calculation process is performed between the set temperature and a compensation threshold to obtain a second compensation temperature;

[0084] The cabin temperature and the second compensation temperature are compared and processed, and when the cabin temperature is lower than the second compensation temperature, the interior fan is controlled to operate.

[0085] Furthermore, when it is determined that the operation mode of the air conditioner is the heating mode, the compressor and the external fan are controlled to stop running, and the internal fan operates normally. Let the compensation threshold be T5, and T5 is 0.5 degrees Celsius.

[0086] The difference calculation process is performed between the set temperature T1 and the compensation threshold T5 to obtain the second compensation temperature T7.

[0087] T7=T1-T5

[0088] Wherein, T7 is the second compensation temperature, T1 is the set temperature, and T5 is the compensation threshold.

[0089] The cabin temperature T3 and the second compensation temperature T7 are compared and processed. If the cabin temperature T3 is lower than the second compensation temperature T7, the interior fan is controlled to operate.

[0090] In some embodiments of the present invention, after the step of controlling the operation of the internal fan, the method further comprises:

[0091] Detecting the temperature at the air outlet of the internal fan to obtain the air outlet temperature;

[0092] The air outlet temperature is compared with the second compensation temperature, and when the air outlet temperature is less than the second compensation temperature, the compressor and the external fan are controlled to operate.

[0093] It can be understood that the temperature at the air outlet is collected by using an air outlet temperature sensor provided at the air outlet of the internal fan to obtain the air outlet temperature T8.

[0094] The air outlet temperature T8 is compared with the second compensation temperature T7. If the air outlet temperature T8 is less than the second compensation temperature T7, the outdoor unit is controlled, that is, the compressor and the outdoor fan are controlled to operate.

[0095] In some embodiments of the present invention, it also includes: during the operation of the RV air conditioner, if the temperature difference T3≤2°C is detected for 60 seconds, the indoor unit sends the current compressor frequency -5Hz to the outdoor unit, and judges every 3 minutes until the current compressor frequency is the minimum frequency P2.

[0096] During the operation of the air conditioner, if the temperature difference T3 is greater than the temperature threshold T4 = 6°C for 60 seconds, the indoor unit sends the current target frequency + 5Hz to the outdoor unit for operation, and the judgment is made every 3 minutes until the current compressor frequency reaches the maximum frequency of the system.

[0097] The present invention provides a control method, device, equipment, storage medium and RV for a motorhome air conditioner, which obtains the set temperature of the air conditioner and detects the temperature in the cabin of the motorhome; calculates the set temperature and the temperature in the cabin to obtain a temperature difference; compares the temperature difference with a preset temperature threshold, and when the temperature difference is greater than or equal to the temperature threshold, sends the compressor frequency generated in the indoor unit to the outdoor unit, the outdoor unit at least including a compressor; determines the target frequency of the compressor based on the compressor frequency received by the outdoor unit and the limited frequency of the outdoor unit, and controls the compressor to operate at the target frequency. By controlling the compressor frequency of the motorhome air conditioner, the motorhome air conditioner can be made quiet and energy-saving.
