Embodiment Construction

[0050] 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.

[0051] Apparently, the illustrated embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0052] In order to facilitate understanding, in the present invention, it is necessary to elaborate on the technical problems therein.

[0053]At present, since the fixed-frequency unit in the fixed-frequency air conditioner cannot adjust the operating frequency of the compressor, when the indoor ambient temperature is equal to or lower than the target set temperature during cooling operation, it is determined that the temperature-reach...

Abstract

The invention provides a fixed-frequency air conditioner control method and device and an air conditioner, and the method comprises the steps of obtaining a target set temperature and a real-time indoor environment temperature after the air conditioner is powered on; judging whether the difference temperature is greater than a first threshold value or not; if yes, starting a compressor and an outer draught fan, and controlling an inner draught fan to operate at a high wind gear; recording the running time of the compressor, and judging the difference temperature; when the difference value temperature is larger than or equal to a third threshold value and is smaller than or equal to a second threshold value, switching the inner draught fan into a low air gear; and after the difference temperature is smaller than the third threshold value and the running time is longer than first preset time, controlling the compressor and the outer fan to be stopped. Thus, the fluctuation range of the indoor environment temperature can be limited below a refrigeration temperature threshold value, the large temperature fluctuation is prevented, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular, to a control method and device for a fixed-frequency air conditioner, and an air conditioner. Background technique [0002] At present, since the fixed-frequency unit cannot adjust the operating frequency of the compressor, when the indoor ambient temperature is lower than the target set temperature during cooling operation, the temperature-up shutdown condition is met, and the air-conditioning system shuts down directly; after the temperature rises during the shutdown period, the air-conditioning system will Start the machine directly for cooling operation. [0003] Under this control method, if there is a large difference between the indoor temperature and the outdoor temperature, after the air conditioning system is shut down, the indoor temperature will rise rapidly and return to the restarting temperature in a short time; Decline rapidly until the air conditi...
