s200, determining a corresponding preset temperature according to an operation mode;
and step S300, controlling the opening and closing state of the first throttling device according to the outdoor environment temperature and the preset temperature.
Specifically, the embodiment of the present invention is used for dealing with a high temperature refrigeration scene or a low temperature heating scene, and therefore, in order to identify whether a current scene is a high temperature refrigeration scene or a low temperature heating scene, an operation mode of an air conditioner needs to be obtained first, and it is determined whether the current operation mode of the air conditioner is a refrigeration mode or a heating mode; then, determining a preset temperature corresponding to the operation mode according to the operation mode, wherein the preset temperatures corresponding to the refrigeration mode and the heating mode are inconsistent; then, the embodiment of the invention obtains the outdoor environment temperature, and judges whether the current scene is a high-temperature refrigeration scene or a low-temperature heating scene according to the outdoor environment temperature and the preset temperature, if the current scene is the high-temperature refrigeration scene or the low-temperature heating scene, the embodiment of the invention controls the first throttling device to be started; if the first throttling device does not belong to the high-temperature refrigeration scene or the low-temperature heating scene, the first throttling device is controlled to be closed.
According to the technical scheme of the embodiment of the invention, the first throttling device and the radiator are additionally arranged, specifically, when the high-temperature refrigerating capacity or the low-temperature heating capacity of the air conditioner needs to be improved according to the outdoor environment temperature and the preset temperature, the first throttling device can be opened, and the liquid refrigerant can flow through the first throttling device through the second refrigerant flow path to become the low-pressure refrigerant; meanwhile, the embodiment of the invention also utilizes the characteristic that an electric control module in the air conditioner is a heating element, so that the low-pressure refrigerant can be changed into a gaseous refrigerant after continuously flowing through a radiator to absorb partial heat and then is injected into an enthalpy-increasing port of the compressor, thereby realizing the enthalpy-increasing operation of the compressor; because the embodiment of the invention does not need to additionally arrange a flash evaporator or a plate heat exchanger, the embodiment of the invention not only can simplify the assembly structure of the air conditioner, but also can reduce the cost.
It should be noted that, as for the above-mentioned obtaining manner of the outdoor environment temperature, the outdoor environment temperature may be collected by setting a temperature sensor, or the outdoor environment temperature corresponding to the current address may be obtained from the internet.
In addition, it is understood that the preset temperature may be set manually or may be automatically generated according to the actual operation condition of the air conditioner and according to a preset rule.
In addition, as shown in fig. 5, fig. 5 is a flowchart of a control method of an air conditioner according to another embodiment of the present invention. In the case that the switch state is on, the control method further includes, but is not limited to, step S400 and step S500.
S400, acquiring the exhaust temperature of a compressor and the temperature of a radiator;
and S500, controlling the opening degree of the first throttling device according to the exhaust temperature of the compressor and/or the temperature of the radiator.
Specifically, after the first throttling device is opened, the embodiment of the invention can also perform adaptive adjustment on the opening degree of the first throttling device. Firstly, after the first throttling device is opened, the embodiment of the invention can acquire the exhaust temperature of the compressor and the temperature of the radiator in real time, and then carry out linkage adjustment on the opening degree of the first throttling device according to the exhaust temperature of the compressor and the temperature of the radiator.
For controlling the opening degree of the first throttling device according to the discharge temperature of the compressor, for example, when the discharge temperature of the compressor is low, the embodiment of the invention may increase the opening degree of the first throttling device; when the discharge temperature of the compressor is higher, the embodiment of the invention can reduce the opening degree of the first throttling device.
For controlling the opening degree of the first throttling device according to the temperature of the radiator, for example, when the temperature of the radiator is higher, that is, the radiator can change more low-pressure refrigerant into gaseous refrigerant to be injected into an enthalpy increasing port of the compressor, for this, the opening degree of the first throttling device can be increased in the embodiment of the present invention; when the temperature of the radiator is lower, namely, the radiator can not change more low-pressure refrigerant into gaseous refrigerant to be injected into the enthalpy-increasing port of the compressor, therefore, the opening degree of the first throttling device can be reduced.

In addition, in the embodiment of the present invention, in addition to controlling the opening degree of the first throttling device according to the discharge temperature of the compressor and/or the temperature of the radiator, the opening degree of the first throttling device according to the outdoor environment temperature may be additionally controlled.

It should be noted that, since the operation modes of the air conditioner are divided into a cooling mode and a heating mode, for the two operation modes, the control manners of the first throttling device, the second throttling device and the third throttling device are all different, and the following description is provided in detail for the two cases of the cooling mode and the heating mode:
in the case that the operation mode is the cooling mode, the controlling of the on-off state of the first throttling device according to the outdoor ambient temperature and the preset temperature in the above step S300 may include, but is not limited to, the two cases of fig. 6 or fig. 7.

Under the condition that the operation mode is a refrigeration mode, the preset temperature corresponds to a first preset temperature; regarding the step S300, there may be, but is not limited to, step S310.
Step S310, when the outdoor environment temperature is higher than a first preset temperature, a first throttling device is started.
As shown in fig. 7, fig. 7 is a flowchart of a control method of an air conditioner according to another embodiment of the present invention. Under the condition that the operation mode is a refrigeration mode, the preset temperature corresponds to a first preset temperature; regarding the step S300, there may be, but is not limited to, step S320.
Step S320, when the outdoor ambient temperature is less than or equal to the first preset temperature, the first throttling device is turned off.
Specifically, in the refrigeration mode, if the outdoor environment temperature is greater than a first preset temperature, it indicates that the current scene is a high-temperature refrigeration scene, and therefore the first throttling device needs to be started; if the outdoor environment temperature is less than or equal to the first preset temperature, the current scene is not a high-temperature refrigeration scene, and therefore the first throttling device does not need to be started.
Exemplarily, if the first preset temperature in the cooling mode is 30 ℃ and the current outdoor environment temperature is 32 ℃, since the outdoor environment temperature is greater than the first preset temperature at this time, it indicates that the current scene is a high-temperature cooling scene, and then the first throttling device needs to be turned on; if the first preset temperature in the refrigeration mode is 30 ℃ and the current outdoor environment temperature is 28 ℃, the current scene is not a high-temperature refrigeration scene because the outdoor environment temperature is lower than the first preset temperature, and the first throttling device does not need to be started.
In addition, as shown in fig. 8, fig. 8 is a flowchart of a control method of an air conditioner according to another embodiment of the present invention. The air conditioner also comprises a second throttling device, a public end is arranged between the first refrigerant flow path and the second refrigerant flow path, and the second throttling device is arranged between the public end and the indoor heat exchanger; the control method further includes, but is not limited to, step S610 and step S620.

The embodiment of the invention can calculate the difference between the discharge temperature of the compressor and the target discharge temperature, then compare the difference with the preset difference, and then control the opening of the second throttling device according to the comparison result.
For example, when the difference between the compressor discharge temperature and the target discharge temperature is negative and smaller than the first preset difference, it indicates that the compressor discharge temperature has not yet reached the target discharge temperature, and for this reason, the embodiment of the present invention may appropriately reduce the opening degree of the second throttling device; when the difference between the compressor discharge temperature and the target discharge temperature is a positive number and greater than a second preset difference, which indicates that the compressor discharge temperature has far exceeded the target discharge temperature, embodiments of the present invention may suitably increase the opening degree of the second throttle device.

And step S340, when the outdoor environment temperature is greater than or equal to a second preset temperature, closing the first throttling device.
Specifically, in the heating mode, if the outdoor environment temperature is lower than a second preset temperature, it indicates that the current scene is a low-temperature heating scene, and therefore the first throttling device needs to be started; if the outdoor environment temperature is greater than or equal to the second preset temperature, the current scene is not a low-temperature heating scene, and therefore the first throttling device does not need to be started.
Exemplarily, if the second preset temperature in the heating mode is 10 ℃ and the current outdoor environment temperature is 8 ℃, since the outdoor environment temperature is lower than the second preset temperature at this time, it indicates that the current scene is a low-temperature heating scene, and the first throttling device needs to be started; if the second preset temperature in the heating mode is 10 ℃ and the current outdoor environment temperature is 12 ℃, since the outdoor environment temperature is higher than the second preset temperature, it is indicated that the current scene is not a low-temperature heating scene, and the first throttling device does not need to be started.
