Problems solved by technology

When the frequency of the compressor is high, due to the poor heat dissipation effect, the condensation of the condenser is not complete, so that the temperature of the condenser is high
[0003] The temperature of the condenser is affected by the speed of the outdoor fan and the frequency of the compressor, so it is not accurate to use the temperature of the condenser to replace the outdoor temperature

Embodiment 1

[0049] A1. When a failure of the outdoor temperature sensor is detected, determine whether the compressor stops running before the failure of the outdoor temperature sensor.

[0050] If yes, execute step A2.

[0051] If not, go to step A5.

[0052] A2. Obtain the current stop operation duration △T.

[0053] If it is detected that the compressor stops running, the compressor stop running timer is started, and the compressor stop running timer stops counting until a failure of the outdoor temperature sensor is detected.

[0054]For example, after the compressor stops running for 30 minutes, it detects that the outdoor temperature sensor has failed, at this time, the chip stops timing, and calculates that the stop running time is 30 minutes.

[0055] A3. Obtain the suction temperature T currently detected by the suction temperature sensor 吸 .

[0056] Suction temperature T 吸 is the temperature detected by the suction temperature sensor located between the compressor and the ...

Embodiment 2

[0066] The length of stop operation △T is different, which means that the suction temperature T 吸 Different from the difference degree of the current outdoor temperature, it is necessary to adjust the suction temperature T according to the length of stop operation △T 吸 Corrected, the obtained suction temperature T 吸 The compensation value is used as the current outdoor temperature T 外 .

[0067] Calculate the suction temperature T according to the following formula 吸 Make a correction:

[0068] When 0外 =T 吸 +c1;

[0069] When t1外 =T 吸 +c2;

[0070] When t2≤ΔT, T 外 =T 吸 ;

[0071] Wherein, t1 is the first duration threshold, t2 is the second duration threshold, t1

[0072] c1 is the first temperature compensation value, c2 is the second temperature compensation value, c1>c2.

[0073] Exemplarily, the first duration threshold t1 is 30 minutes, or other values; the second duration threshold t2 is 60 minutes, or other values; the first temperature compensation valu...

[0079] Corresponding to the aforementioned embodiments of the method for implementing application functions, the present application also provides an air conditioner detection device and corresponding embodiments.

[0080] figure 2 It is a schematic structural diagram of the air conditioner detection device shown in the embodiment of the present application.

[0081] see figure 2 , the air conditioner testing equipment includes: a data acquisition device 2000 and a controller 1000 ; wherein, the controller 1000 includes: a memory 1010 and a processor 1020 .

[0082] In the embodiment of the present application, the data acquisition device is connected to the controller, and is used to obtain the suction temperature detected by the suction temperature sensor or the outdoor temperature value stored in the chip and send it to the controller, and the controller is used to The parameters collected by the data collection device are obtained, and the above-mentioned detection met...

Abstract

The invention relates to an outdoor temperature sensor fault operation method, air conditioner detection equipment and an air conditioner. The method comprises the steps that when it is detected that an outdoor temperature sensor breaks down, whether a compressor stops running or not before the outdoor temperature sensor breaks down is judged; if yes, the compensation value of the suction temperature Tsuction serves as the current outdoor temperature; the compensation value of the air suction temperature is a temperature value obtained by correcting the air suction temperature according to the operation stopping duration; the operation stopping duration is the interval duration from operation stopping of the compressor to detection of failure of the outdoor temperature sensor; the suction temperature is a temperature value detected by a suction temperature sensor located between the compressor and the gas-liquid separator. According to the scheme provided by the invention, temperature compensation can be carried out on the suction temperature of the suction sensor according to the running stop duration under the condition that the outdoor temperature sensor is detected to have a fault and the compressor stops running, and the temperature is used as the current outdoor temperature.

Description

technical field [0001] The present application relates to the field of intelligent control of air conditioners, in particular to an outdoor temperature sensor failure operation method, air conditioner detection equipment and an air conditioner. Background technique [0002] During the operation of the air conditioner, there is a certain probability that the outdoor temperature sensor will fail. The usual solution is to stop the air conditioner system and wait for the maintenance personnel to come to deal with it. From the system shutdown to the completion of maintenance, the air conditioner has been unavailable, resulting in poor user experience. An alternative is to use the condenser temperature instead of the outdoor temperature, but in the case of poor heat dissipation conditions, the air fluidity is poor, and the speed of the outdoor fan is small, which makes the condenser temperature higher. In the case of good heat dissipation conditions, the air flow is better, and t...
