[0039] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of an air conditioner operation control device in the hardware operation environment involved in the embodiment of the present invention.

The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0042] Those skilled in the art will understand that Figure 1The structure shown in the figure does not constitute a limitation on the operation control device of the air conditioner, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0043] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and an operation control program of the air conditioner.

[0044] exist Figure 1 In the operation control device of the air conditioner shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the operation control device of the air conditioner of the present invention can be set in the operation control device of the air conditioner, and the operation control device of the air conditioner calls the operation control program of the air conditioner stored in the memory 1005 through the processor 1001, and executes the operation control method of the air conditioner provided by the embodiment of the present invention.

[0045] The embodiment of the present invention provides an operation control method of an air conditioner, referring to Figure 2 , Figure 2 FIG1 is a flow chart of a first embodiment of an operation control method for an air conditioner according to the present invention.

[0046] In this embodiment, the operation control method of the air conditioner includes the following steps:

[0047] Step S10: After the compressor of the air conditioner runs at an initial frequency for a first period of time, the outdoor ambient temperature of the area where the compressor is located and the outlet temperature and inlet temperature of the thermal storage oil separator are obtained.

[0048] It should be noted that the execution subject of this embodiment may be the air conditioner device, which has functions such as data processing, data communication, and program execution. The air conditioner device may be a controller for a multi-split air conditioner. Of course, other devices with similar functions may also be used, and this implementation condition does not impose any restrictions on this.

[0049] It is worth noting that the air conditioner in this embodiment refers to an air conditioner variable frequency system or a heat pump variable frequency system, which can realize the function of adjusting parameters such as air temperature, humidity, cleanliness and air flow rate in the room, including but not limited to cooling, heating, defrosting and fresh air circulation modes.

[0050] It should be noted that the reference Figure 3The air conditioner in this embodiment includes: a compressor 1, a thermal storage oil separator 2, a four-way valve 3, an outdoor heat exchanger 4, a throttling element 5, an indoor heat exchanger 6, an indoor fan 7, an outdoor fan 8, a vapor-liquid separator 9, an oil return capillary 10 and a filter 11, wherein the output end of the compressor 1 is connected to the input end of the thermal storage oil separator 2, and the output end of the thermal storage oil separator 2 is connected to the indoor heat exchanger 6 or the outdoor heat exchanger 4 through the four-way valve 3. In the heating mode, the output end of the thermal storage oil separator 2 is connected to the indoor heat exchanger 6 or the outdoor heat exchanger 4 through the four-way valve. 3 is connected to the indoor heat exchanger 6; in the cooling mode or the defrosting mode, the output end of the thermal storage oil separator 2 is connected to the outdoor heat exchanger 4 through the four-way valve 3, wherein the indoor fan 7 is installed at the indoor heat exchanger 6, and the outdoor fan 8 is installed at the outdoor heat exchanger 4. The return oil capillary 10 is connected to the thermal storage oil separator 2 through the filter 11. The thermal storage oil separator in this embodiment can be a filter-type oil separator with heat storage material, or can be a packing type, a centrifugal type, a washing type, etc., and this embodiment does not impose specific restrictions on this.

[0051] In the specific implementation, when the air conditioner is in heating operation, the refrigerant is compressed by the compressor to obtain high-temperature and high-pressure refrigerant. The high-temperature and high-pressure refrigerant is transported to the indoor heat exchanger through the four-way valve for condensation and heat dissipation. After the indoor heat exchanger exchanges heat with the indoor environment, medium-temperature and high-pressure refrigerant is obtained. Then, through throttling elements such as the electronic expansion valve and the main capillary tube, low-pressure and medium-temperature refrigerant is obtained, which is transported to the outdoor heat exchanger for evaporation to obtain low-temperature and low-pressure refrigerant. Finally, it flows back to the compressor through the four-way valve to complete a single heating process.

[0052] It can be understood that this embodiment can distinguish different starting frequencies and durations according to the ambient temperature and exhaust temperature of the area where the compressor is located. The temperature is increased by the self-heating of the compressor at low frequency operation, thereby separating the oil and the refrigerant. The refrigeration oil returns to the compressor through the oil separator, but the above process will cause the starting process to take too long, the heating effect is slow, and the user experience is poor; or additional auxiliary electric heating is added to the exhaust port to increase the exhaust temperature. The electric heating situation of the exhaust is increased to increase the temperature of the refrigerant and the refrigeration oil, so that the electric heating power consumption of the refrigeration oil separation is large, and long-term use will increase a lot of energy consumption. At the same time, it is necessary to increase the electronic control components, which increases the risk of failure.

[0053] In addition, the solubility characteristics of the lubricating oil and refrigerant mixture are related to temperature. Generally speaking, the higher the temperature of the lubricating oil and refrigerant mixture, the lower the solubility. Therefore, if the outlet temperature of the thermal storage oil separator is higher, it can indicate to a certain extent that the solubility of the lubricating oil and the refrigerant is lower, and the less lubricating oil is carried out of the compressor. Therefore, this embodiment applies heat to the refrigerant flowing out of the compressor through the thermal storage oil separator, further heating the refrigerant, reducing the solubility of the refrigerant and the lubricating oil, and thus reducing the outflow of lubricating oil.

[0054] In a specific implementation, the initial frequency can be the lowest frequency supported by the air conditioner compressor, generally 30-60HZ, and the first duration ranges from 30s to 90s. In this embodiment, the first duration can be set to 60s, and this embodiment does not impose specific restrictions on this.

[0055] It should be noted that the ambient temperature of the area where the compressor is located refers to the outdoor ambient temperature, which can be collected by a temperature collection device installed on the outdoor heat exchanger, or by a temperature collection device on the outer casing of the air conditioner. The temperature collection device can be a temperature sensor or a temperature sensing package, or other equipment that can realize the temperature collection function. This embodiment does not impose specific restrictions on this.

[0056] In a specific implementation, the outlet temperature of the thermal storage oil separator can be collected by the temperature sensor between the compressor and the thermal storage oil separator, and the inlet temperature of the thermal storage oil separator can be collected through the refrigerant pipe installed between the thermal storage oil separator and the four-way valve.

[0057] Step S20: Correcting the initial frequency according to the outlet temperature, the inlet temperature, and the outdoor ambient temperature to obtain a current operating frequency.

[0058] It should be noted that, in this embodiment, the solubility of the mixture of lubricating oil and refrigerant can be determined by first judging the temperature range in which the outlet temperature is located. If the temperature range in which the outlet temperature is located is high, it means that the solubility is low, and the initial frequency of the compressor can be increased or the operation of the air conditioner can be controlled normally; if the temperature range in which the outlet temperature is located is moderate, it means that the solubility is low, and the initial frequency of the compressor can only be increased appropriately to avoid insufficient lubrication due to high-frequency operation of the compressor, which may lead to damage to the compressor; if the temperature range in which the outlet temperature is located is extremely low, it is necessary to maintain the compressor running at the initial frequency to increase the overall refrigerant temperature.

[0059] In this embodiment, if the outlet temperature is in a moderate temperature range, it is necessary to increase the operating frequency of the compressor while ensuring that the lubricating oil does not flow out too much. Therefore, when adjusting the operating frequency of the compressor, the outdoor ambient temperature of the area where the compressor is located and the outlet temperature and inlet temperature of the thermal storage oil separator can be combined to obtain the current operating frequency of the compressor.

[0060] Step S30: controlling the compressor to operate at the current operating frequency.

[0061] It is understandable that when controlling the compressor to operate at the current operating frequency, it is necessary to ensure that the current operating frequency does not exceed the rated operating frequency of the compressor to avoid damaging the compressor.

[0062] This embodiment controls the operation of the air conditioner compressor at a lower initial frequency. After a period of time, the operating frequency of the compressor is comprehensively adjusted according to the ambient temperature around the compressor and the inlet and outlet temperatures of the thermal storage oil separator, thereby improving the heating effect of the compressor. At the same time, when the temperature is low, the operation of the compressor is controlled at a relatively low frequency to reduce the outflow of lubricating oil, thereby avoiding the technical problem in the prior art that the compressor may be damaged due to insufficient lubrication when the air conditioner is started for heating, thereby improving the user experience.

[0063] refer to Figure 4 , Figure 4 FIG2 is a flow chart of a second embodiment of an operation control method for an air conditioner according to the present invention.

[0064] Based on the above first embodiment, in this embodiment, step S20 includes:

[0065] Step S201: when the outlet temperature is lower than a first temperature and higher than a second temperature, calculating a temperature difference between the outlet temperature and the inlet temperature, the first temperature being higher than the second temperature.

[0066] It should be noted that the value range of the first temperature can be 50575°C, and the value range of the second temperature can be 10525°C. In this embodiment, the first temperature is 60°C and the second temperature is 20°C as an example for description.

[0067] It can be understood that the temperature difference between the outlet temperature and the inlet temperature refers to the outlet temperature of the thermal storage oil separator minus the inlet temperature of the thermal storage oil separator.

[0068] Step S202: Determine a target frequency correction value corresponding to the outdoor ambient temperature.

[0069] It should be noted that since the temperature range of the outlet temperature is moderate, the initial frequency of the compressor will be appropriately increased. In this process, considering the influence of the outdoor ambient temperature on the solubility of the lubricating oil and refrigerant mixture, the frequency correction value for adjusting the compressor operating frequency can be determined by the outdoor ambient temperature. In this embodiment, the target frequency correction value is positively correlated with the outdoor ambient temperature, that is, the higher the outdoor ambient temperature, the larger the target frequency correction value; the lower the outdoor ambient temperature, the smaller the target frequency correction value. In this embodiment, the target frequency correction value can range from 1 to 1.5.

[0070] Furthermore, in order to accurately calculate the target frequency correction value corresponding to the outdoor ambient temperature, step S202 includes:

[0071] When the outdoor ambient temperature is greater than or equal to a second temperature, obtaining a rated operating ambient temperature of the air conditioner;

[0072] A target frequency correction value is obtained by calculation according to the rated operating environment temperature and the second temperature.

[0073] It is understandable that the rated operating ambient temperature of the air conditioner refers to the maximum ambient temperature operating range in which the air conditioner can operate, that is, the maximum temperature at which the air conditioner can operate normally.

[0074] In a specific implementation, if the outdoor ambient temperature is greater than or equal to 20°C, the formula for calculating the target frequency correction value is:

[0075]

[0076] Among them, β refers to the target frequency correction value, T4 refers to the outdoor ambient temperature of the area where the compressor is located, and T4 max Refers to the rated operating ambient temperature, and K2 refers to the second temperature.

[0077] In addition, if the outdoor ambient temperature is lower than the second temperature, the target frequency correction value is set to the preset frequency correction value. In this embodiment, the preset frequency correction value is 1, which is the minimum value of the target frequency correction value.

[0078] Step S203: When the temperature difference is greater than or equal to a preset temperature threshold, correcting the initial frequency according to the target frequency correction value and a preset first frequency correction value.

[0079] It should be understood that the preset temperature threshold is used to determine the temperature range of the outlet temperature and the inlet temperature of the thermal storage oil separator, thereby enabling more accurate adjustment of the compressor operating frequency.

[0080] In a specific implementation, the specific formula for correcting the initial frequency according to the target frequency correction value and the preset first frequency correction value is:

[0081] Fr2=Fr1*α1*β

[0082] Among them, Fr2 refers to the corrected initial frequency, that is, the current operating frequency of the compressor, Fr2 refers to the initial frequency, α1 refers to the preset first frequency correction value, and its value range is greater than 1, and β refers to the target frequency correction value.

[0083] Step S204 : When the temperature difference is less than a preset temperature threshold, correcting the initial frequency according to the target frequency correction value and a preset second frequency correction value, and the second frequency correction threshold is less than the second frequency correction threshold.

[0084] In a specific implementation, the specific formula for correcting the initial frequency according to the target frequency correction value and the preset second frequency correction value is:

[0085] Fr2=Fr1*α2*β

[0086] Among them, Fr2 refers to the corrected initial frequency, that is, the current operating frequency of the compressor, Fr2 refers to the initial frequency, α2 refers to the preset second frequency correction value, and its value range is greater than 1, and the preset second frequency correction value is less than the preset first frequency correction value, and β refers to the target frequency correction value.

[0087] Furthermore, in the above calculation, there may be a situation where the current operating frequency obtained after correction is greater than the rated operating frequency of the air conditioner compressor in the current state. Therefore, when the current operating frequency is greater than the preset operating frequency, the current operating frequency can be corrected to the preset operating frequency. The preset operating frequency refers to the rated operating frequency of the air conditioner compressor in the current operating state. The preset operating frequency is related to the current operating mode of the air conditioner, the air conditioner model and the operating parameters.

[0088] In addition, if the outlet temperature of the thermal storage oil separator is greater than the first temperature of 60°C, it indicates that the temperature of the mixture of refrigerant and lubricating oil is higher and the solubility is lower, and the probability of damage to the compressor is lower. Therefore, the air conditioner can be controlled to operate normally according to the mode and parameters set by the user.

[0089] If the outlet temperature of the thermal storage oil separator is lower than the second temperature of 20°C, it indicates that the temperature of the mixture of refrigerant and lubricating oil is too low, and the lubricating oil may even freeze. At this time, if the compressor is high frequency, the probability of damage to the compressor is extremely high. The current operating frequency of the compressor can be maintained at the initial frequency for a period of time, and then its outlet temperature can be detected to see if it meets the frequency modulation conditions. Therefore, in this embodiment, after the air conditioner is started, the air conditioner control method described above can be executed at intervals to avoid damage to the air conditioner compressor.

[0090] In addition, considering that when the air conditioner is running the heating function at low temperature, it is affected by the low outdoor temperature environment, and the outdoor heat exchanger may be frosted. In the initial startup, the refrigerant temperature output by the compressor is not high. At this time, the refrigerant at the compressor outlet can be reheated through the heat storage oil separator to improve the defrosting efficiency.

[0091] Among them, the defrost mode of the air conditioner means that the air conditioner is in a low temperature environment. Because the air conditioner is heating, the temperature of the outdoor heat exchanger of the outdoor unit is low, resulting in frost. At this time, by reversing the four-way valve, the outdoor heat exchanger is used as a condenser, thereby increasing the temperature of the outdoor heat exchanger, which is similar to the heating mode. At this time, the outdoor heat exchanger is a condenser and the indoor heat exchanger is an evaporator.

[0092] Furthermore, in order to ensure that the air conditioner can meet the user's heating needs, when the current operating frequency of the air conditioner's compressor is greater than or equal to the preset frequency threshold, or the continuous operation time of the air conditioner is greater than the preset time, the air conditioner can be controlled to operate normally according to the mode, parameters and duration set by the user to meet the user's heating needs.

[0093] In this embodiment, by increasing the inlet temperature, outlet temperature and T4 correction coefficient of the thermal storage oil separator, multi-parameter coupling control adjustment can not only ensure the reliable startup of the compressor, but also shorten the startup phase duration according to actual parameters, realize rapid heating of the air conditioner, and improve the user experience.

[0094] In addition, an embodiment of the present invention further provides a storage medium storing an operation control program for an air conditioner. When the operation control program for the air conditioner is executed by a processor, the steps of the operation control method for the air conditioner described above are implemented.

[0095] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0096] Reference Figure 5 , Figure 5 FIG. 1 is a structural block diagram of a first embodiment of an operation control device for an air conditioner according to the present invention.

[0097] like Figure 5 As shown, the operation control device of the air conditioner proposed in the embodiment of the present invention includes:

[0106] In one embodiment, the control module 30 is further configured to control the air conditioner to operate normally when the current operating frequency is greater than or equal to a preset operating frequency, or when the continuous operation time of the air conditioner is greater than a preset time.

[0107] The present embodiment discloses an operation control method for an air conditioner, wherein the air conditioner is provided with a compressor for adjusting the temperature of a refrigerant, and a heat storage oil separator for separating a lubricating fluid and a refrigerant is provided at the outlet of the compressor.
