Embodiment Construction

[0058]Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0059] It should be noted that the terms "first" and "second" in the specification, claims and drawings of the present disclosure are used to distinguish similar objects, and are not necessarily interpreted as describing a specific sequence or sequence.

[0060] In the related technology, the on-board air conditioner compressor is controlled to work at a fixed speed. When the temperature reaches the target temperature, the compressor is controlled to work at a low speed or the compressor is controlled to stop working. When the temperature reaches the starting temperature of the compressor, the compressor is controlled to start again at a fixed speed. Work. Co...

Abstract

The invention relates to a vehicle-mounted air conditioner compressor rotating speed control method and device, a vehicle-mounted air conditioner and a vehicle. The method comprises the steps that a compressor is controlled to run for preset time at the set rotating speed; when the preset time is up, the difference value between the actual evaporation temperature value and the target evaporation temperature value of an evaporator of the vehicle-mounted air conditioner is determined, and the following operations are started to be executed: the first target gradient grade where the difference value is located is determined; a first compressor rotating speed and a first preset duration corresponding to the first target gradient grade are determined; the rotating speed of the compressor is adjusted to the first compressor rotating speed within the first preset duration; and when the first preset duration is up, the difference value between the actual evaporation temperature value and the target evaporation temperature value of the evaporator is determined again. In this way, the rotating speed of the compressor in the refrigeration process can be reasonably controlled according to the difference value between the actual evaporation temperature value and the target evaporation temperature value of the evaporator.

Description

technical field [0001] The present disclosure relates to the technical field of automatic air-conditioning, and in particular, to a method and device for controlling the rotational speed of a vehicle-mounted air-conditioning compressor, a vehicle-mounted air conditioner, and a vehicle. Background technique [0002] The difference between the automatic air conditioner and the manual air conditioner is that the automatic air conditioner automatically controls the output power and air volume of the compressor according to the set target temperature, and quickly lowers the temperature to the set temperature value, without the need for the driver and passengers to manually adjust the air volume multiple times The size reduces the potential safety hazard during driving. In the cooling process of the automatic air-conditioning system, controlling the compressor speed is of great significance to improving the comfort, so that the temperature of the air outlet is smooth and fine, whi...
