Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure.
In the related art, an air outlet temperature sensor is usually added at an air outlet of an air conditioner to obtain the air outlet temperature of the air conditioner, but the air outlet temperature of the air conditioner measured by the method has larger error and lower accuracy. Meanwhile, some air conditioners are not allowed due to cost or structural conditions, and the air conditioner air outlet temperature is difficult to measure under the condition that an air outlet temperature sensor is not designed at an air outlet of the air conditioner.
The application provides a method for determining air conditioner air outlet temperature, which is used for determining the air outlet temperature of an air conditioner based on each working coefficient of the air conditioner or the system inherent coefficient of the air conditioner, so that the air conditioner without an air outlet temperature sensor added at the air outlet of the air conditioner can obtain the air outlet temperature of the air conditioner. Meanwhile, the method can be used for replacing the air outlet temperature sensor of the air conditioner to participate in corresponding control when the air outlet temperature sensor of the air conditioner has faults, or judging whether the air conditioner is in an abnormal state or not by detecting the air outlet temperature of the air conditioner and calculating the air outlet temperature of the air conditioner.
Fig. 1 is a flowchart illustrating a method for determining an air conditioner outlet air temperature according to an exemplary embodiment, where as shown in fig. 1, the method for determining the air conditioner outlet air temperature includes the following steps.
In step S11, in response to determining that the conditions for calculating the outlet air temperature are satisfied, the inner tube temperature and the inlet air temperature of the air conditioner are obtained.
In the embodiment of the present disclosure, the condition for calculating the outlet air temperature may include determining that the air conditioner is turned on and operated for a period of time or that the air conditioning system is in a steady state. And acquiring the temperature of the inner pipe collected by a temperature sensor arranged on the inner pipe of the air conditioner. And simultaneously acquiring the air inlet temperature collected by a temperature sensor arranged at the air inlet of the air conditioner.
In step S12, the outlet air temperature of the air conditioner is determined according to the inner pipe temperature and the inlet air temperature.
In the embodiment of the present disclosure, the air outlet temperature of the air conditioner may be calculated by using the obtained inner tube temperature and the obtained air inlet temperature, so as to determine the air outlet temperature of the air conditioner.
According to the method for determining the air conditioner air outlet temperature, the air conditioner air outlet temperature can be obtained without adding a temperature sensor at the air conditioner air outlet by obtaining the temperature obtained by the existing sensor of the air conditioner, and calculation of the air conditioner air outlet temperature is facilitated.
The following embodiments of the present disclosure further explain and explain the method for determining that the conditions for calculating the outlet air temperature are satisfied in the above embodiments of the present disclosure.
Fig. 2 is a flowchart illustrating a method for determining that a condition for performing a wind outlet temperature calculation is satisfied according to an exemplary embodiment, and as shown in fig. 2, the method for determining that the condition for performing the wind outlet temperature calculation is satisfied includes the following steps.
In step S21, a compressor frequency of the air conditioner, a compressor characteristic parameter of the air conditioner, and an outdoor unit current of the air conditioner are acquired.
In the embodiment of the present disclosure, the frequency of the air conditioner compressor may be measured as follows: for example, the compressor speed may be measured. The universal meter can also be used for testing the frequency of the input power supply at the compressor end. The test can also be performed using an oscilloscope.
In the embodiment of the disclosure, the characteristic parameters of the air conditioner compressor may be related to the displacement and the mechanical structure of the air conditioner, and may be obtained through experiments under a standard environment according to the air conditioner. Wherein the standard environment is an outdoor environment between-5 ℃ and 35 ℃.
In the embodiment of the present disclosure, the current of the outdoor unit of the air conditioner may be measured in the following manner: the total current of the outdoor unit is given by a Micro Control Unit (MCU) of the air conditioning system, and the current can be calculated by connecting a non-inductive resistor with a small resistance value in series in the system and adopting a resistor shunt mode.
In step S22, a system characteristic value is determined based on the compressor frequency, the compressor characteristic parameter, and the outdoor unit current.
In the embodiment of the disclosure, the characteristic value of the air conditioning system is obtained by fitting calculation according to the frequency of the compressor, the characteristic parameter of the compressor and the current of the outdoor unit.
In step S23, if the system characteristic value is less than or equal to the preset threshold, it is determined that the condition for calculating the outlet air temperature is satisfied.
In the embodiment of the present disclosure, the preset threshold may be determined according to the air conditioner in a test in a standard environment. The system characteristic value can judge whether the current air-conditioning system is in a stable state or not, and whether the frequency of the compressor of the air-conditioning system is matched with the current of the outdoor unit or not.
According to the method for determining the condition meeting the calculation of the outlet air temperature, the characteristic value representing whether the air conditioner runs stably is obtained by obtaining the existing sensor of the air conditioner or measuring the relevant working parameters of the air conditioner outside the air conditioning system.

In step S32, if the system characteristic value is greater than the preset threshold, the determination of the outlet air temperature of the air conditioner is cancelled.
In the embodiment of the present disclosure, if the system characteristic value is greater than the preset threshold, it may be determined that the system is currently unstable, or the refrigerant flow is smaller than the design value due to reasons such as severe fluorine deficiency, or an abnormal condition occurs at the present time in the system, which may cause an excessively low outdoor unit current or an excessively high compressor frequency. And if the system is unstable, the calculation of the air outlet temperature of the air conditioner is cancelled.
According to the method for determining the condition meeting the air outlet temperature calculation condition, whether the air conditioning system is in a steady state or not is judged through the system characteristic value, and the step of calculating the air outlet temperature of the air conditioner is simplified or not.

In step S41, an inner pipe compensation value of the air conditioner is determined, and a refrigerant shortage compensation coefficient of the air conditioner is determined.
In the embodiment of the disclosure, the compensation value of the inner pipe of the air conditioner is related to the position of the flow path of the indoor heat exchanger of the air conditioner or the temperature sensor of the heat exchanger of the air conditioner. When the air conditioner is in a heating mode, the value of the inner pipe compensation value of the air conditioner can be 3-5 ℃. When the air conditioner is in a refrigeration mode, the value of the inner pipe compensation value of the air conditioner can be between minus 1.5 ℃ and minus 1 ℃.
In the embodiment of the present disclosure, the refrigerant shortage compensation coefficient of the air conditioner may be determined according to the system characteristic value.
In step S42, an equivalent coil temperature is determined based on the inner tube compensation value, the refrigerant starvation compensation factor, and the inner tube temperature.
In the embodiment of the disclosure, the equivalent coil temperature can be obtained by calculating according to the inner tube compensation value, the refrigerant lack compensation coefficient and the inner tube temperature fitting.

In the embodiment of the disclosure, the air inlet temperature of the air conditioner can be obtained according to the temperature sensor arranged at the air inlet of the air conditioner.
In step S52, a wind speed correction coefficient is determined based on the rotation speed of the indoor circulating fan of the air conditioner and the characteristic coefficient of the air conditioner.
In the embodiment of the present disclosure, the rotating speed of the indoor circulating fan of the air conditioner may be the maximum rotating speed of the outdoor unit of the air conditioner, and the unit is rpm.

The value range of the characteristic coefficient b can be 1050-1800, and the characteristic coefficient b is larger than the characteristic coefficient a.
In step S53, the difference is corrected based on the wind speed correction coefficient to obtain a correction value.
