Compared with the traditional electric heating mode, the electromagnetic reaction heating has higher heat conversion rate, and is more efficient and energy-saving.

Here, the induction coil 21 may be provided in contact with the flash evaporator 10, or may be provided in non-contact with the flash evaporator, and when the magnetizer 22 is provided in the alternating magnetic field of the induction coil 21, the magnetizer 22 may generate an eddy current in the energized state of the induction coil 21.

Optionally, the induction coil 21 is sleeved on the outer wall of the flash evaporator 10. Here, the induction coil 21 is disposed in contact with the flash evaporator 10. The induction coil 21 is arranged on the outer wall of the flash evaporator 10, so that the magnetizer 22 in the flash evaporator 10 is arranged in the alternating magnetic field generated by the induction coil 21, and the magnetizer 22 generates heat to heat the refrigerant in the flash evaporator 10 under the electrifying state of the induction coil 21, thereby forming a gaseous refrigerant and providing a stable air supplement amount for the compressor.

At this time, the liquid level in the flash evaporator 10 is low, and when the control power is turned on, the heat generated by the magnetizer 22 is large, and the heat that can be absorbed by the refrigerant with a small volume is also small, which is likely to cause a failure.

Here, the first threshold value refers to the currently required air supplement amount of the compressor. When the air flow is greater than or equal to the first threshold value and the current air supplement amount is too large, the controller 40 reduces the heating power of the electromagnetic heating module 20 to slow down the output of the gaseous refrigerant; when the air flow is smaller than the first threshold value, the current air supplement amount is smaller, and at this time, the controller 40 increases the heating power of the electromagnetic heating module 20 to accelerate the output of the gaseous refrigerant.

As shown in fig. 6, the air conditioner includes a refrigerant circulation circuit formed by connecting a compressor 50, a four-way valve 52, an indoor heat exchanger, and an outdoor heat exchanger through pipes. The gas refrigerant outlet 11 of the flash evaporator 10 is connected to the compressor air supplementing port 51 through a pipeline, the liquid refrigerant outlet 13 of the flash evaporator 10 is arranged at the bottom of the flash evaporator 10 and is connected with the evaporator 54 through a pipeline; the refrigerant input pipe 12 of the flash evaporator 10 is arranged at the top of the flash evaporator 10, the output end of the refrigerant input pipe 12 extends to the bottom of the flash evaporator 10 inside the flash evaporator, and the input end of the refrigerant input pipe 12 is connected with the condenser 53 through a pipe. Wherein, a solenoid valve 55 is arranged between the gaseous refrigerant outlet 11 and the compressor air supplementing port 51; a first throttling device 56 is arranged between the liquid refrigerant outlet 13 and the evaporator 54; a second throttling device 57 is arranged between the refrigerant inlet and the condenser 53; the controller 40 is connected to the solenoid valve 55, and controls the opening degree of the solenoid valve 55 according to the operating state of the electromagnetic heating module 20. That is, when the electromagnetic heating module 20 is turned on, the electromagnetic valve 55 is opened, the pipeline in which the electromagnetic valve is located is conducted, and the gaseous refrigerant generated by heating the liquid refrigerant entering the flash evaporator 10 flows to the compressor air supplement port 51 through the electromagnetic valve 55 via the gaseous refrigerant outlet 11 at the top of the flash evaporator 10.

The operation of the air supply device for the compressor in the air conditioner will be described below by taking the heating state of the air conditioner as an example. In a normal heating state, the compressor 50 compresses a low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, the refrigerant flows to an indoor heat exchanger (condenser 53) through the four-way valve 52 and is condensed into a liquid refrigerant, and the process is a heat release process to realize indoor heating; the liquid refrigerant enters the flash evaporator 10 through the refrigerant input pipeline 12 after being throttled by the second throttling device 57, enters the outdoor heat exchanger (evaporator 54) through the first throttling device 56 through the liquid refrigerant outlet 13 to be evaporated and absorb heat, and then turns into the gas refrigerant which flows to the suction port of the compressor 50 through the four-way valve 52 to complete the primary cycle.

In the case where it is necessary to supplement air to the compressor 50 to increase the refrigerant circulation amount in the low-temperature cooling state or the like, the controller 40 opens the electromagnetic valve 55 and controls the electromagnetic heating module 20 to heat the flash evaporator 10, as shown in fig. 7. The gaseous refrigerant generated by heating the liquid refrigerant entering the flash evaporator 10 flows to the compressor air supplement port 51 through the gaseous refrigerant outlet 11 at the top of the flash evaporator 10 via the electromagnetic valve 55. Because the magnetizer 22 is arranged in the flash evaporator 10, and the induction coil 21 is arranged outside the flash evaporator 10, the liquid refrigerant in the flash evaporator 10 can be directly heated, the heat loss in the heating process is reduced, the heating efficiency is higher, the heating is uniform, the increase of the refrigerant circulation amount of the compressor is realized by supplying air to the compressor 50, and the low-temperature heating effect of the air conditioner is obviously improved.
