Embodiment 1

[0034] Such as figure 1 As shown, an operation method for controlling the reliability of an air conditioner includes the following steps:

[0035] According to the temperature signal sent by the temperature sensor, it is judged whether the temperature sensor is invalid. If so, the air conditioner continues to obtain the real-time outdoor ambient temperature. After the various operating parameters of the system continue to run; otherwise, continue to run in normal mode.

[0036] The control method of the present invention can continue to control the normal operation of the air conditioner after the temperature sensor fails, satisfying people's normal use.

Embodiment 2

[0038] Such as figure 2 As shown, an operation method for controlling the reliability of an air conditioner specifically includes the following steps:

[0039] S1. Determine whether the temperature sensor detection deviates from the normal range by ±55°C, and if so, continue to count the time that continues to deviate from the normal range; otherwise, continue to operate in the normal mode;

[0040] S2. Judging whether the time of continuous deviation from the normal range is greater than the first preset time, if yes, it is determined that the sensor is invalid; otherwise, continue to operate according to the normal mode;

[0041] The range of the first preset time is: 40-70s; preferably, the first preset time is: 60s.

[0042] It should be noted that the first preset time can be changed according to experimental data or the model of the air conditioner.

[0043] S3. After determining that the sensor is invalid, obtain the outdoor ambient temperature in real time; automati...

Embodiment 3

[0049] The difference between this embodiment and the above-mentioned embodiment is that after automatically matching the various operating parameters of the system corresponding to the current outdoor ambient temperature, it also includes steps:

[0050] S4. After automatically matching the various operating parameters of the system corresponding to the current outdoor ambient temperature, the air conditioner performs automatic matching every 2 minutes during operation. The invention can effectively prevent other parameter changes caused by load changes.

Abstract

The invention provides an operation method for controlling the reliability of an air conditioner, a control system and the air conditioner. The operation method for controlling the reliability of theair conditioner comprises the following steps that whether a temperature sensor fails or not is judged according to a temperature signal sent by the temperature sensor, if the temperature sensor fails, the air conditioner continues to acquire real-time outdoor environment temperature, the air conditioner automatically matches each operation parameter of the system corresponding to the outdoor temperature according to the real-time outdoor temperature, and continues to operate according to each operation parameter of the system after automatic matching; and otherwise, normal mode operation is continued. The operation method for controlling the reliability of the air conditioner can continuously control normal operation of the air conditioner after the temperature sensor fails, so that the normal use of people is met.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an operation method and system for controlling the reliability of an air conditioner and an air conditioner. Background technique [0002] At present, during the operation of the inverter air conditioner, various temperature sensors are required to detect and continuously feed back to the electronic control in real time to guide the compressor and various components to perform actions. After long-term operation, the resistance value of the temperature sensor changes or the temperature sensor fails. For the reliability of the air conditioner, the air conditioning unit cannot run during the failure of the temperature sensor. And if the air conditioner cannot operate in the summer, the indoor temperature cannot meet people's normal living environment, which will affect people's normal rest. Contents of the invention [0003] In view of this, the present invention aims to...
