Disclosed are a variable capacity compressor operation mode determination method and device, a variable capacity compressor and an air conditioner. The variable capacity compressor operation mode determination method includes: detecting a current value of a compressor at present as A1 before switching an operation mode of the compressor; detecting the current value of the compressor at present as A2 after switching the operation mode of the compressor and reaching a preset time; comparing A1 and A2, determining that the switching of the operation mode of the compressor is successful when a ratio relationship between A1 and A2 satisfies a preset condition, and determining that switching of the operation mode of the compressor is failed when the ratio relationship between A1 and A2 dissatisfies a preset condition.

Provided are a method and device for controlling electric heating of an air conditioner compressor. The method may include: first request information is transmitted to a corresponding database server at an interval of a second preset duration, as to acquire weather forecast data of an area where an air conditioner is located within an upcoming third preset duration; the weather forecast data returned by the database server is received and stored in a built-in database of the air conditioner; it is monitored to learn that a shutdown duration of the air conditioner compressor exceeds a first preset duration, as to acquire the weather forecast data stored in the built-in database of the air conditioner; and a control strategy is generated according to the weather forecast data, to control the air conditioner compressor to start and stop electric heating.
