Description
Technical field
The present invention relates to air-conditioning technical field, be specifically related to the control method that a kind of convertible frequency air-conditioner intelligence enters silent mode.
Background technology
The indoor fan rotating speed of current split convertible frequency air-conditioner is generally 5 grades, is respectively powerful wind wind shelves, high wind wind shelves, apoplexy wind shelves, low wind wind shelves and gentle breeze wind shelves.Under normal refrigeration, heating mode, user can only use low wind wind shelves, and gentle breeze wind shelves are only just used when heating anti-cold wind.
As user needs a quiet environment, generally need to press quiet key and enter silent mode, under normal refrigeration, heating mode, convertible frequency air-conditioner cannot enter silent mode.Convertible frequency air-conditioner is when freezing or heating mode runs; if refrigerating capacity or heating capacity too much; and running frequency lower when; the compressor of convertible frequency air-conditioner usually can be out of service; and when the difference between indoor environment temperature and the design temperature of user preset meets certain relation time, compressor restarts again.Probably like this can cause high frequent start and stop, and on the impact caused the service life of compressor to a certain degree, and for user, user does not wish because the frequent start-stop of cooler compressor causes indoor environment temperature sometimes hot and sometimes cold yet.
Summary of the invention
An object of the present invention is to provide a kind of convertible frequency air-conditioner intelligence to enter the control method of silent mode, can be improved the comfortableness of convertible frequency air-conditioner by the method, be reduced the noise of energy consumption and indoor set thereof.
