Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.
In the related art, an air outlet temperature sensor is added at an air outlet of the 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 outlet temperature of the air conditioner is difficult to measure under the condition that an air outlet temperature sensor is not designed at the air outlet of the air conditioner.
The application provides a method for determining the air-out temperature of an air conditioner, which is used for determining the air-out temperature of the air conditioner based on each working coefficient of the air conditioner or the inherent coefficient of a system of the air conditioner, so that the air conditioner without adding an air-out temperature sensor at the air outlet of the air conditioner can obtain the air-out temperature of the air conditioner. And the method can also 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 fails, or judging whether the air conditioner is in an abnormal state by detecting the air outlet temperature of the air conditioner and the calculated air outlet temperature of the air conditioner.
Fig. 1 is a flowchart illustrating a method of determining an air-conditioner outlet temperature according to an exemplary embodiment, and the method of determining an air-conditioner outlet temperature includes the following steps as shown in fig. 1.
In step S11, in response to determining that the air outlet temperature calculation condition is satisfied, the inner tube temperature and the air inlet temperature of the air conditioner are acquired.
In an embodiment of the present disclosure, performing the air outlet temperature calculation condition may include determining that the air conditioner is turned on for a period of time or that the air conditioning system is in a steady state. And acquiring the temperature of the inner pipe acquired by a temperature sensor arranged on the inner pipe of the air conditioner. And meanwhile, the air inlet temperature acquired by a temperature sensor arranged at the air inlet of the air conditioner is acquired.
In step S12, the outlet air temperature of the air conditioner is determined according to the temperature of the inner pipe and the inlet air temperature.
In the embodiment of the disclosure, the obtained inner tube temperature and the obtained air inlet temperature can be adopted to calculate the air outlet temperature of the air conditioner, and the air outlet temperature of the air conditioner is determined.
According to the method for determining the air outlet temperature of the air conditioner, the air outlet temperature of the air conditioner can be obtained by obtaining the temperature obtained by the existing sensor of the air conditioner without adding the temperature sensor at the air outlet of the air conditioner, and calculation of the air outlet temperature of the air conditioner is facilitated.

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 disclosure, the frequency of the air conditioner compressor can be measured in the following manner: for example, the compressor speed may be measured. The multimeter can also be used for testing the frequency of the input power supply at the compressor end. An oscilloscope may also be used for testing.
In the embodiment of the disclosure, the characteristic parameters of the air conditioner compressor can be related to the displacement and the mechanical structure of the air conditioner, and can be obtained according to experiments of the air conditioner in a standard environment.

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 calculated according to the compressor frequency, the compressor characteristic parameter and the outdoor machine current fitting.
In step S23, if the system characteristic value is less than or equal to the preset threshold value, it is determined that the condition for calculating the air outlet temperature is satisfied.
In the embodiment of the disclosure, the preset threshold value may be determined according to the air conditioner when testing in a standard environment. The system characteristic value can judge whether the current air conditioning system is in a steady state or not, and whether the frequency of the compressor of the air conditioning system is matched with the frequency of the outdoor machine current or not.
According to the method for determining whether the air-out temperature calculation conditions are met or not, the characteristic value representing whether the air conditioner operates stably is obtained by acquiring the existing sensor of the air conditioner or measuring the relevant working parameters of the air conditioner outside an air conditioning system.

In step S32, if the system characteristic value is greater than the preset threshold value, the determination of the outlet air temperature of the air conditioner is canceled.
In the embodiment of the disclosure, if the system characteristic value is greater than the preset threshold value, it may be determined that the system is currently unstable, or the refrigerant flow is smaller than the design value due to serious fluorine deficiency and other reasons, or the system is currently abnormal, so that the outdoor current is low or the frequency of the compressor is too high. And if the system is unstable, the calculation of the air outlet temperature of the air conditioner is canceled.
According to the method for determining whether the air-conditioning system is in the steady state or not according to the system characteristic value, the air-conditioning temperature calculation condition is met, and the step of calculating the air-conditioning air-out temperature is simplified or not.
