Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present application clearer, the present application 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 application, and are not intended to limit the present application.

[0035] This embodiment provides a control method for adjusting the frequency of the air conditioner compressor 110, which is used to prevent the operating frequency of the compressor 110 from oscillating due to the triggering of exhaust protection during a period of time when the air conditioner 100 is started. This control method is preferably executed when the air conditioner 100 is running in cooling mode after starting up, because in the cooling mode of the air conditioner, the ambient temperature of the outdoor unit of the air conditioner 100 is high, and the exhaust t...

Abstract

The invention provides a control method used for frequency adjusting of an air conditioner compressor and a refrigerator. The method comprises the steps of obtaining outdoor environment temperature ofenvironment where an outdoor unit of an air conditioner is located, and according to the outdoor environment temperature, determining the exhaust target temperature of the compressor; obtaining the starting event of the compressor, and controlling the compressor to run at the initial frequency; detecting the exhaust temperature of the compressor, and determining the temperature rise speed of theexhaust temperature; after the preset compressor adjusting time is achieved, judging whether the temperature rise speed is larger than the preset first speed threshold value or not; if not, increasingthe compressor running frequency to the set frequency value, and returning to execute detection of the exhaust temperature again, and determining of the temperature rise speed until the exhaust temperature is larger than the exhaust target temperature. The running frequency of the compressor can be improved only when the condition that the rising speed of the exhaust temperature is smaller than the first speed threshold value is met, and the oscillating of the running frequency of the compressor can be well avoided.

Description

technical field [0001] The invention relates to an air conditioner control method, in particular to a control method for frequency regulation of an air conditioner compressor and an air conditioner. Background technique [0002] In the existing air conditioners, in order to ensure a good cooling and heating effect, on the premise of protecting the compressor, the frequency of the compressor should be increased as much as possible to increase its exhaust temperature. In addition to current protection, the compressor is more likely to perform exhaust protection by detecting the exhaust temperature. [0003] At present, when the air conditioner is turned on, the compressor frequency will directly increase to the maximum operating frequency. When the compressor runs directly at the maximum operating frequency, its exhaust temperature rises rapidly, so it is very easy to trigger the exhaust protection program set in the system. For example, if the discharge protection is set to...
