Compared with the prior art, the air conditioner has the beneficial effects that:
when the air conditioner is used as a single-cooling air conditioner, the first control valve and the second control valve are in a closed state under the regulation of a user, at the moment, a refrigerant in the circulating system is compressed into a high-temperature high-pressure gaseous form by the compressor, the gaseous refrigerant is sent into the outdoor heat exchanger, the outdoor heat exchanger exchanges heat with the high-temperature high-pressure gaseous refrigerant to be cooled to change the high-temperature high-pressure gaseous refrigerant into a normal-temperature high-pressure liquid form, the first control valve and the second control valve are in the closed state, the refrigerant in the circulating system cannot flow to the circulating pump through the first control valve and cannot be communicated with the indoor heat exchanger through the second control valve, the refrigerant at the moment is depressurized into a low-temperature low-pressure gas-liquid two-phase state through the throttling component, enters the indoor heat exchanger, and absorbs heat in the indoor heat exchanger to return to the compressor in a low-pressure low-temperature gaseous form, and the indoor heat exchanger reduces the temperature of indoor air due to heat absorption of the refrigerant, so that the refrigerant circulation of a normal refrigeration mode is completed, and the refrigeration demand is realized. Further, when the user needs to cool the sealed room under the condition that the outdoor environment temperature is low and the indoor temperature is high, the air conditioner can be controlled to enter a special low-temperature cooling mode, the compressor is controlled to stop running at the moment, the circulating pump is started, the first control valve and the second control valve are opened, the refrigerant in the circulating system flows at normal pressure along the direction opposite to the flowing direction of the refrigerant in the normal cooling mode under the driving of the circulating pump, the refrigerant exchanges heat with the outdoor low-temperature air at the outdoor heat exchanger to be changed into a normal-pressure low-temperature state, and then enters the indoor heat exchanger through the first control valve and the circulating pump, the refrigerant in the normal-pressure low-temperature state exchanges heat with the indoor high-temperature air at the indoor heat exchanger, and then the low-temperature cooling function in the outdoor low-temperature room is realized.

In addition, the air conditioner is further provided with an electric control assembly which is electrically connected with the components of the outdoor heat exchanger 2, the indoor heat exchanger 1, the compressor 4, the circulating pump 5, the first control valve 6, the second control valve 7 and the like and used for controlling the opening and closing of the components.
Based on the above structure, when the air conditioner is used as a single-cooling type air conditioner, the first control valve 6 and the second control valve 7 are in a closed state under the regulation of a user, at this time, the refrigerant in the circulating system is compressed into a high-temperature high-pressure gaseous form by the compressor 4 and is sent into the outdoor heat exchanger 2, the outdoor heat exchanger 2 exchanges heat with the high-temperature high-pressure gaseous refrigerant to cool the high-temperature high-pressure gaseous refrigerant so as to change the high-temperature high-pressure gaseous refrigerant into a normal-temperature high-pressure liquid form, because the first control valve 6 and the second control valve 7 are both in the closed state, the refrigerant in the circulating system cannot flow to the circulating pump 5 through the first control valve 6 and cannot be communicated with the indoor heat exchanger 1 through the second control valve 7, the refrigerant at this time is depressurized into a low-temperature low-pressure gas-liquid two-phase state through the throttling component 3 and enters the indoor heat exchanger 1, and absorbs heat in the indoor heat exchanger 1 to return into the compressor 4 in a low-temperature low-pressure gaseous form, and the indoor heat exchanger 1 reduces the temperature of the indoor air due to heat absorption of the refrigerant, and then the refrigerant circulation in a normal refrigeration mode is completed, and the refrigeration requirement is realized.

Because the refrigerant circulation avoids the throttling component 3 of the circulation system, the refrigerant does not need to throttle, the resistance of the whole circulation system is small, the refrigerant exchanges heat and circulates in a normal pressure state, the circulation pump 5 only needs to provide small pressure difference to realize the normal flow of the refrigerant, the small pressure difference is insufficient to enable the refrigerant to pass through the stalled compressor 4 to form a loop, and the refrigerant at the moment can only avoid the compressor 4 to circulate along the circulation pump 5, the first control valve 6, the outdoor heat exchanger 2, the second control valve 7 and the indoor heat exchanger 1, so that the low-temperature refrigeration function in the outdoor low-temperature indoor high temperature is realized.
