The invention relates to a preheating control method of an air conditioner compressor and an air conditioner. The preheating control method comprises the following steps that S1, an outdoor unit is controlled to be powered on; S2, an outdoor environment temperature To is collected, and compared with a preset outdoor temperature Tp, delta E=To-Tp is obtained; S3, when delta E is less than or equalto 0, an outdoor environment temperature Ti is collected; and S4, the situation that at least three preset temperature ranges of which Ti is in is determined, whether a user starting-up record existsin a preset temperature range or not is determined, if not, the S2 is returned, if yes, a user normal starting-up time point within the preset temperature range is determined, pre-heat is generated ata preset time before the user normal starting-up time point which is closest to the current time point, and the compressor is preheated with the pre-heat, wherein multiple temperature boundaries areset to divide the indoor temperature into at least three consecutive preset temperature ranges. Reduction of energy consumption is achieved, the preheating efficiency is improved, and user experienceis improved.
Description
technical field [0001] The invention belongs to the technical field of central air conditioning, and in particular relates to an air conditioner compressor preheating control method and an air conditioner. Background technique [0002] In recent years, the demand for air conditioners in various places has continued to expand, especially in northern areas where air conditioners are used for heating under low temperature conditions in winter. When the air conditioner is under low temperature outdoor conditions, the lubricating oil in the oil pool inside the compressor has a high viscosity, which requires a huge torque to start the compressor. In order to avoid damage to the compressor caused by a large torque, before starting the The compressor needs to be preheated to ensure that the lubricating oil meets the reliability requirements after the compressor starts. In order to realize the preheating of the compressor, an electric heating belt is installed on the outer wall of t...
