Embodiment Construction

[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0033] Such as figure 1 As shown, the control method of the air conditioner compressor in this embodiment includes the following steps:

[0034] Step (1), when the air conditioner is on standby, determine whether the air conditioner compressor is running; if so, proceed to step (6); if not, monitor the outdoor temperature in real time, and proceed to the next step;

[0035] Step (2), judging whether the outdoor temperature ≤ set temperature T1+2°C is established; if not, proceed to step (6); if yes, proceed to the next step;

[0036] Among them, the set temperature T1 refers to the minimum temperature of the lubricating oil when the air conditioner compressor can start smoothly. When the air conditioner leaves the factory, it is set in the form...

Abstract

A control method of an air conditioning compressor includes that if the air conditioning is in a standby state and the air conditioning compressor stops working, a coil of the air conditioning compressor soaked in refrigerants with lubricating oil is automatically communicated with direct current with a certain current, and the coil fevers and heats the lube, when the outdoor temperature is too low (minus 20 degrees). The control method not only solves the problem that the air conditioning compressor cannot be started due to the fact that temperature of the lubricating oil is too low, and has the advantages of being energy-saving and environmental-friendly in control process.

Description

technical field [0001] The invention relates to a control method of an air conditioner compressor, which belongs to the field of indoor air conditioning. Background technique [0002] There is refrigerant and lubricating oil in the cavity of the air conditioner compressor. Lubricating oil lubricates soaked bearings, rotating mechanisms, etc. When the outdoor temperature is too low in winter (such as -20°C), the viscosity of the lubricating oil increases and the lubricating function is greatly reduced. The air conditioner compressor often cannot be started, and even start-up wear, burnout and other adverse problems occur. [0003] For this reason, some air conditioner compressors have heating bands installed on their crankcases. When the outdoor temperature is too low, the heating belt is energized to generate heat, heat the crankcase, and then indirectly heat the lubricating oil through the crankcase, so that the viscosity of the lubricating oil becomes smaller, thereby en...
