Embodiment 1
[0029] Embodiment 1, a method for controlling a compressor.
[0030] This embodiment provides a compressor control method, including the following steps:
[0031] S1: Set the current of the motor 7 of the compressor 1 to X times the initial current;
[0032] The adjustment of the current magnitude when the motor 7 is in normal operation varies according to the load condition of the system. When the load of the compressor 1 is heavy and the torque requirement is large, the current passing through the motor 7 of the compressor 1 increases accordingly. Conversely, when the load of the compressor 1 is small and the torque requirement is small, the current passing through the motor 7 of the compressor 1 also decreases accordingly. After the compressor 1 is energized, the control module sets the current of the motor 7 of the compressor 1 to 1.4 times of the initial current, and realizes internal heating of the compressor 1 through the coil of the motor 7 of the compressor 1 and th...
Embodiment 2
[0039] Embodiment 2, a compressor.
[0040] This embodiment provides a compressor such as figure 1 As shown, the compressor 1 of this embodiment is used to realize the control method of the compressor 1 described in the first embodiment.
[0041] Compressor 1 includes current transmission line 2, heating resistance wire, lubricating oil 5, motor 7, lubricating oil 5 temperature detection device, exhaust temperature detection device and control module, one end of current transmission line 2 is connected to the coil of motor 7, the other end of current transmission line 2 One end is connected to one end of the heating resistance wire, the other end of the heating resistance wire is immersed in the lubricating oil 5, the lubricating oil 5 temperature detection device is set in the lubricating oil 5, the lubricating oil 5 temperature detection device is connected to the first port of the control module, and the exhaust The temperature detecting device is arranged at the exhaust ...

Abstract
The present invention provides a compressor, a control method, and an air conditioner. The control method of the compressor includes the following steps: S1: setting the current of the motor of the compressor to X times the initial current; S2: obtaining the discharge of the compressor in real time Air temperature T and lubricating oil temperature K; S3: The current of the motor of the compressor is adjusted according to the magnitudes of the fed back exhaust gas temperature T and lubricating oil temperature K. The invention adopts the method of increasing the motor current of the compressor at low frequency to increase the calorific value of the motor coil in the low-frequency operation state, and at the same time heats up through the heating resistance wire to heat the temperature of the refrigerant in the shell and the temperature of the lubricating oil in the compressor to increase the compression The effect of the exhaust temperature in the machine cavity increases the temperature of the lubricating oil at the same time, so that the temperature of the lubricating oil increases and the viscosity decreases, thereby ensuring the capacity and reliability of the compressor, reducing the power consumption of the compressor, and increasing the energy efficiency.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor, a control method and an air conditioner. Background technique [0002] At present, there are many air conditioners in the industry that use capillary tubes as throttling components in small household air-conditioning systems. Capillary tubes are widely used by most air-conditioning manufacturers because of their low cost and no moving parts. However, the adjustment ability of the capillary tube is poor, and the liquid supply volume cannot be adjusted arbitrarily according to the change of working conditions. Therefore, in the air conditioning system using the capillary tube as the throttling element, the state of the refrigerant at the outlet of the evaporator is unstable under the low-frequency working condition, and the degree of superheat is low. As a result, the suction state of the compressor is unstable, and there is liquid in the suction, so that there is...
