Problems solved by technology

[0004] Based on this, it is necessary to address the above technical problems and provide a control method, an air conditioner, and a storage medium for re-powering on the air conditioner after power-off, aiming at solving the problems that are prone to occur when the air-conditioner is power-off and then on in the prior art. Two air conditioners start at the same time, causing the problem that the local power grid cannot operate normally

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Such as figure 1 As shown, the control method for powering on again after the air conditioner provided by the present invention includes steps:

[0036] S100. Obtain the AD value of the indoor ambient temperature sensor and / or the AD value of the indoor coil temperature sensor. The AD value refers to the value after converting the analog quantity (such as voltage, current) into a digital quantity. Usually, the formula AD=(V / VCC)*2^n=(NTC / (NTC+R))*2^n can be used Calculate, where V is the input voltage, VCC is the standard voltage, R is the fixed resistance, and NTC is the thermistor. Sinc...

Abstract

The present invention relates to a control method for powering on an air conditioner after it is powered off, the air conditioner and a storage medium. The method includes: acquiring the AD value of an indoor ambient temperature sensor and / or the AD value of an indoor coil temperature sensor; and then according to The AD value of the indoor ambient temperature sensor and / or the AD value of the indoor coil temperature sensor calculates a random value T according to preset rules; finally, the compressor is controlled to start after extending the standby time for T seconds. Based on this, the control method for powering on the air conditioner after power-off provided by the present invention can randomly prolong the start-up time of the compressor according to the random value calculated separately for each air-conditioner, and disperse the start-up time of the air-conditioner so that the same time The number of activated air conditioners is reduced, thereby reducing the impact on the grid and reducing the probability that the grid cannot operate normally due to excessive impact.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method for powering on the air conditioner after power failure, the air conditioner and a storage medium. Background technique [0002] With the development and progress of air conditioner technology, it is more intensively used in batches in public places such as schools, hospitals, hotels and other places. In order to facilitate management, most of the air conditioners used in batches are air conditioners with power-down memory function. However, when these regional power grids are powered off and then powered on again, multiple (or even dozens of) air conditioners will be started at the same time. Since the air conditioner compressor is an inductive load, the current at the moment of starting may be several times the rated current, which will cause a huge impact on the power grid. Due to the excessive impact current, it may cause some electrical appliances ...
