Background
When the variable frequency air conditioner operates, multiple protection measures are designed for ensuring the operation reliability of the compressor, so that the compressor is prevented from operating for a long time under the conditions of high current, high temperature and high pressure. Such as condensation temperature overload protection, can trigger overload protection when the system is in high pressure operation, and frequency is reduced, so that the system pressure is controlled within a reasonable range.
However, if the high pressure is not very high, but the low pressure is abnormally low, the compression ratio is abnormally increased, and when the compressor runs for a long time under the abnormally high compression ratio, the crankshaft of the compressor can be distorted and eccentric due to acting force generated by the high pressure ratio, so that the crankshaft of the compressor is eccentrically worn, and finally the cylinder of the compressor is blocked and cannot be operated.
Currently, variable frequency air conditioners are generally designed with high pressure protection of a system, but the high pressure protection is not carried out correspondingly, and once the air conditioner operates for a long time under certain severe working conditions, the high pressure protection can lead to damage of a compressor.

Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
[ first embodiment ]
Referring to fig. 1, the present embodiment provides a control method of an air conditioner, where the control method includes:
s100: acquiring the ambient temperature of the air conditioner;
s200: determining an operating frequency upper limit value of a compressor of the air conditioner according to the ambient temperature, and controlling the operating frequency of the compressor to be smaller than or equal to the operating frequency upper limit value;
wherein the ambient temperature includes an outdoor ambient temperature, or an outdoor ambient temperature and an indoor ambient temperature.
In this embodiment, a control method of an air conditioner is provided, where in implementation, it is required to obtain an ambient temperature of the air conditioner, and then determine an operating frequency upper limit value of a compressor of the air conditioner according to the ambient temperature, where the frequency of the compressor cannot be higher than the operating frequency upper limit value when the compressor is operating. The ambient temperature may include an outdoor ambient temperature, and may also include an outdoor ambient temperature and an indoor ambient temperature.
Further, in S100, it is necessary to sense the ambient temperature through a temperature sensor in the air conditioner, that is, sense the outdoor ambient temperature, or sense the outdoor ambient temperature and the indoor ambient temperature, and after detecting the ambient temperature, transmit the detected temperature value to the controller of the air conditioner, so as to help the controller of the air conditioner to perform the subsequent frequency control action on the compressor.
Further, in S200, the controller of the air conditioner determines an operation frequency upper limit value of the compressor of the air conditioner according to the ambient temperature, and the current operation frequency of the compressor cannot exceed the operation frequency upper limit value. The method comprises the steps of judging whether the current air conditioner is in a high compression ratio state or not according to the current environment temperature of the air conditioner, and controlling the operation frequency upper limit value of the compressor of the air conditioner under the condition that the current air conditioner is in the high compression ratio state, namely the high compression ratio state, so that the compression ratio of the compressor is always in a reasonable range.
Illustratively, when the air conditioner is in the heating mode, the outdoor ambient temperature is lower than the indoor ambient temperature, which is typically between 20 degrees and 30 degrees. When the environment temperature obtained by the air conditioner only comprises the outdoor environment temperature, if the outdoor environment temperature is 10 ℃, the outdoor temperature is higher, the evaporation pressure is higher, namely the low pressure is higher, the compression ratio of the compressor is not very high, and the upper limit value of the running frequency of the compressor can be controlled at a higher level; when the environment temperature obtained by the air conditioner comprises the outdoor environment temperature and the indoor environment temperature, if the indoor temperature is 30 ℃ higher at this time, the outdoor temperature is 20 ℃ below zero, the evaporation pressure is lower at this time, namely the low pressure is lower, the compression ratio of the compressor is easy to be too high, the upper limit value of the operation frequency of the compressor needs to be controlled at a lower level at this time, and the situation that the operation frequency of the compressor is too high to cause the compression ratio of the compressor is avoided.
For example, when the air conditioner controls the upper limit value of the operation frequency of the compressor, it may be implemented in such a manner that the ambient temperature of a certain section corresponds to a certain upper limit value of the operation frequency of the compressor. The environment temperature and the upper limit value of the operation frequency of the compressor are in one-to-one correspondence, so that the air conditioner can be helped to quickly respond to the corresponding actual environment condition, and the protection of the compressor is realized.
It can be appreciated that the prior art is generally designed with high pressure protection of the system, but for the case of high compression ratio, the prior art generally detects high pressure and low pressure values, and adjusts the frequency of the compressor when the compression ratio exceeds a certain limit value according to the high pressure and low pressure values; in the scheme of the invention, the upper limit value of the running frequency of the compressor is controlled according to the ambient temperature of the air conditioner. The upper limit value of the running frequency of the compressor corresponding to different environment temperatures is different, and the scheme of the invention controls the upper limit value of the running frequency of the compressor through the actual environment temperature of the air conditioner, so that the upper limit value of the running frequency of the compressor can be more suitable for different environment temperatures; meanwhile, the scheme of the invention controls the upper limit value of the operating frequency of the compressor, namely the operating frequency of the compressor does not exceed the upper limit value of the operating frequency of the compressor, and the scheme ensures the operating efficiency of the compressor under the condition of safe operation, and effectively avoids the abrasion problem of the compressor caused by the long-term high-pressure ratio condition of the compressor.
[ second embodiment ]
In a specific embodiment, the control method is performed with the air conditioner operating in a heating mode.
In the present embodiment, the control method of the air conditioner needs to be performed in a case where the air conditioner is operated in the heating mode. Specifically, when the air conditioner is in refrigeration operation, the indoor temperature is comfortable temperature sensed by human body, the indoor temperature is not too low, and the indoor temperature is basically unlikely to exceed the allowable compression ratio range of the compressor, so that a control method for protecting the high-pressure ratio is not needed in the refrigeration mode; when the air conditioner is in heating operation, the evaporating pressure is lower due to the lower outdoor temperature, and the compression ratio exceeds the allowable value due to the higher indoor temperature, so the control method of high-pressure ratio protection is needed in heating mode.
It can be understood that the control method of the air conditioner is only executed when the air conditioner operates in a heating mode, namely, the control is performed under the condition that the high-pressure ratio is most likely to occur, and the control method is not executed under the condition that the high-pressure ratio is not likely to occur, so that the control process of the control method of the embodiment is effectively simplified, the control computing resource of the air conditioner controller is saved, and the operation efficiency of the air conditioner is further improved.
[ third embodiment ]
In a specific embodiment, in case the outdoor ambient temperature is greater than or equal to the first threshold value, the ambient temperature comprises only the outdoor ambient temperature; in the case that the outdoor ambient temperature is less than the first threshold, the ambient temperature includes an outdoor ambient temperature and an indoor ambient temperature.
In this embodiment, when the air conditioner is operated in the heating mode, the outdoor environment temperature is higher than or equal to the first threshold value, that is, the low pressure is higher, and since the indoor environment temperature is a comfortable temperature for the human body, the compression ratio is generally not too high, and therefore the compression ratio is operated in the allowable compression ratio range of the compressor, in this case, the operation frequency upper limit value of the compressor at this time can be determined only by the outdoor environment temperature, and the operation frequency upper limit value at this time can be controlled in a higher state; in the case where the outdoor ambient temperature is less than the first threshold value, the outdoor temperature is low at this time, i.e., the low pressure is low, and when the indoor ambient temperature is high, the compression ratio exceeds the allowable value, and therefore, in this case, it is necessary to control the upper limit value of the operation frequency of the compressor by the outdoor ambient temperature and the indoor ambient temperature.
It will be appreciated that the upper limit value of the operating frequency of the compressor is controlled according to different temperatures in different situations, i.e. in situations where an indoor ambient temperature is not required, the upper limit value of the operating frequency of the compressor may be controlled only by the outdoor ambient temperature. The scheme of the embodiment can improve the operation efficiency of the control method and the practicability of the control method.
[ fourth embodiment ]
In a specific embodiment, the air conditioner stores a preset frequency upper limit value, and determines an operation frequency upper limit value of a compressor of the air conditioner according to an ambient temperature, including:
s210: determining a frequency limiting coefficient of the compressor according to the ambient temperature;
s220: the operating frequency upper limit is determined based on the product of the multiplication of the frequency limiting coefficient and the preset frequency upper limit.
In this embodiment, the air conditioner stores a preset frequency upper limit value, which is a highest frequency preset according to the compression ratio of the compressor after laboratory testing before the air conditioner leaves the factory, that is, the compressor cannot exceed the preset frequency upper limit value when running. And the value obtained after multiplying the frequency limiting coefficient and the preset frequency upper limit value is the current running frequency upper limit value of the compressor.
Further, in S210, a frequency limiting coefficient of the compressor is determined according to the ambient temperature. Specifically, the temperature range of the environmental temperature can be a temperature range corresponding to a frequency limiting coefficient.
Further, in S220, an operation frequency upper limit value is determined based on a product of multiplication of the frequency limit coefficient and a preset frequency upper limit value. And multiplying the frequency limiting coefficient corresponding to the current environment temperature by a preset frequency upper limit value to obtain the current running frequency upper limit value of the compressor.
It will be appreciated that the scheme of the present embodiment uses a frequency limiting coefficient to obtain the operating frequency upper limit value. The logic level of the control method is optimized, different fixed frequency limiting coefficients are output according to different environment temperatures, the output operation frequency upper limit value can be more in line with the current environment, the normal operation of the air conditioner is ensured while the compressor is protected, and the user experience is improved.
[ fifth embodiment ]
In a specific embodiment, the range of values of the frequency limiting coefficient is: greater than 0 and less than or equal to 1.
In the present embodiment, the upper limit value of the operating frequency of the compressor cannot exceed the preset upper limit value of the frequency, and thus the frequency limiting coefficient cannot be greater than 1.
It can be appreciated that the scheme of the embodiment can ensure that the current running frequency of the compressor is not too high, and improves the safety of the whole system.
[ sixth embodiment ]
In a specific embodiment, determining the frequency limiting coefficient of the compressor based on the ambient temperature includes:
s211: determining a frequency limiting coefficient of the compressor according to the outdoor environment temperature under the condition that the outdoor environment temperature is smaller than a second threshold value and the indoor environment temperature is larger than a third threshold value, wherein the value of the frequency limiting coefficient is high when the outdoor environment temperature is high; and/or
S212: in the case where the indoor environmental temperature is less than or equal to the third threshold value, the frequency limiting coefficient is determined to be a fixed value that is not related to the outdoor environmental temperature.
In the practical application process, the second threshold value in the present embodiment is the same as the first threshold value in the third embodiment.
Further, in S211, when the outdoor ambient temperature is less than the second threshold and the indoor ambient temperature is greater than the third threshold, the outdoor ambient temperature is lower, the evaporation pressure is lower, i.e. the low pressure is lower, when the indoor ambient temperature is higher, the compression ratio of the compressor easily exceeds the safety range, when the outdoor ambient temperature is higher, the low pressure is higher, the possibility of occurrence of a high compression ratio is reduced, and the upper limit value of the operating frequency of the compressor, i.e. the value of the frequency limiting coefficient, can be appropriately increased.
Further, in S212, in the case where the indoor environment temperature is less than or equal to the third threshold, the indoor environment temperature is low at this time, the condensing pressure is low, that is, the high pressure is low, and the compression ratio of the compressor at this time does not substantially exceed the compression ratio range in which the compressor operates, so that the frequency limiting coefficient can be determined directly from the indoor environment temperature.
