Embodiment Construction

[0046] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] An embodiment of the present invention provides a compressor quick start control method, including:

[0048] When the compressor is running in the preset frequency-up mode, the following parameters are obtained: the saturation temperature corresponding to the suction pressure of the compressor, the saturation temperature corresponding to the discharge pressure of the compressor, the outdoor ambient temperature and the indoor ambient temperature;

[0049] According to the parameters, it is judged whether the preset conditions are met;

[0050] When the preset condition is satisfied, the compressor is controlled to stop increasing the frequency, so that the compressor maintains the current frequency operation.

[0051] Wherein, the p...

Abstract

The invention provides a compressor quick start control method and device, an air conditioner and a storage medium. The compressor quick start control method comprises the steps that when a compressoroperates in a preset frequency rising mode, the following parameters including the saturation temperature corresponding to the suction pressure of the compressor, the saturation temperature corresponding to the exhaust pressure of the compressor, the outdoor environment temperature and the indoor environment temperature are obtained; whether a preset condition is met or not is determined according to the parameters; and when the preset condition is met, the compressor is controlled to stop frequency increasing, and the compressor is made to operate at the current frequency. According to the invention, the compressor frequency increasing process is buffered by maintaining the current frequency of the compressor, protection shutdown caused by too fast frequency increasing of the compressoris avoided, a guarantee is provided for fast and reliable starting of the compressor, and the situation that the user experience comfort is reduced due to frequent frequency increasing and decreasingof the compressor is avoided.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a compressor quick start control method and device, an air conditioner and a storage medium. Background technique [0002] For air-conditioning systems, especially multi-connected systems, in order to meet the user's demand for rapid cooling and heating of the room, most air-conditioning manufacturers will control the compressor by quickly starting it, so that the compressor can be raised to a higher frequency in a short period of time, so as to Output greater capacity. However, in the process of rapid frequency increase of the compressor, the air conditioner failure protection shutdown caused by "too fast frequency increase" often occurs, which brings an uncomfortable experience to the user. Contents of the invention [0003] The problem solved by the present invention is that existing compressors cannot be started quickly and reliably. [0004] In order to ...
