Abstract

The invention discloses a control method and device of a compressor electric heating band. The control method and device is characterized in that the highest value and the lowest value of the first temperature which reflects the temperature of a compressor oil tank are determined, the current value of the first temperature is detected, the electric heating band is controlled to be in an off state when the current value is larger than the highest value, unnecessary electric energy consumption is reduced, the standby power of an air conditioner is lowered, and energy conservation performance of the air conditioner is increased; when the current value is smaller than the lowest value, the electric heating band is controlled to be turned on so as to heat lubricating oil; when the current value is larger the lowest value and smaller than the highest value, the electric heating band is kept to be in a current state. By the control method and device, timely on/off of the electric heating band is achieved, unnecessary electric energy consumption of the air conditioner is reduced under the premise that the temperature of the lubricating oil satisfies requirements, the standby power of the air conditioner is lowered, the energy conservation performance of the air conditioner is increased, and problems in the prior art are solved.

Description

technical field [0001] The present application relates to the technical field of refrigeration control, in particular to a method and device for controlling an electric heating belt of a compressor. Background technique [0002] After the air conditioner compressor is shut down, it is necessary to ensure that the lubricating oil has a certain degree of superheat to prevent the refrigerant from migrating into the lubricating oil and diluting the lubricating oil; at the same time, it is necessary to avoid the rapid vaporization of the lubricating oil due to the low temperature when the compressor starts up again. resulting in a reduction in lubricating oil. For this reason, prior art is provided with an electric heating belt in compressor; When compressor starts, this electric heating belt is de-energized, and this electric heating belt is powered on when compressor shuts down, starts to heat lubricating oil. [0003] Although the above control method achieves the purpose of ...
