In this embodiment, the indoor energy storage heat exchanger 4 may be used to store cold, and the circulation pump 6 may be used to control the indoor energy storage heat exchanger 4 to release cold, so as to circulate cold in the energy release loop.
It will be appreciated that the indoor energy storing heat exchanger 4 is in the off state before the compressor 1 is started when the air conditioner is on. When the refrigeration working condition is a low-temperature refrigeration working condition and meets a preset first condition, the indoor energy storage heat exchanger 4 is controlled to start cold accumulation, and when the refrigeration working condition is a high-temperature refrigeration working condition and meets a preset second condition, the circulating pump 6 is started to release the cold energy of the indoor energy storage heat exchanger 4 to carry out cold energy circulation in the energy release loop, so that the effect of cooling the refrigerant in the second outdoor heat exchanger 3 is achieved.

Since the working scenario of this embodiment is when the air conditioner is in the cooling mode, when the indoor ambient temperature is lower than the air conditioner set temperature, it indicates that the cooling capacity of the air conditioner is greater than the load of the room.

It should be understood that when the first cut-off valve 8 is closed and the second cut-off valve 9 is opened, the refrigerant flows into the indoor energy-storing heat exchanger 4 first and then flows into the indoor heat exchanger 5. At this time, the indoor energy storage heat exchanger 4 can perform cold accumulation; when the first stop valve 8 is opened and the second stop valve 9 is closed, the refrigerant directly flows into the indoor heat exchanger 5, and at this time, the indoor energy storage heat exchanger 4 stops accumulating cold.

It can be understood that, if the cold accumulation of the indoor energy storage heat exchanger 4 is insufficient, and the temperature difference between the secondary refrigerant and the indoor energy storage heat exchanger 4 is small, the cold released at this time is circulated, the cooling effect may not be good and the indoor cooling effect is not good, and therefore, whether the indoor energy storage heat exchanger 4 is controlled to release the cold needs to be judged according to the first temperature difference value Δ T1.
It should be understood that after the first temperature difference Δ T1 is determined, the first temperature difference Δ T1 may be compared with a first preset temperature C2, wherein C2 is a set value, and the embodiment is not limited to the specific value thereof. When the first temperature difference value delta T1 is greater than the first preset temperature C2, the cold accumulation of the indoor energy storage heat exchanger 4 is sufficient at the moment, and the circulating pump 6 is started; controlling the circulating pump 6 to operate in a preset gear mode to control the indoor energy storage heat exchanger 4 to release cold energy for cold energy circulation; when the first temperature difference value delta T1 is less than or equal to the first preset temperature C2, the cold accumulation of the indoor energy storage heat exchanger 4 is insufficient, and the indoor energy storage heat exchanger 4 is not controlled to release cold.
