At S102, in response to the operation mode of the air conditioner being a heating mode, the first four-way valve and the second four-way valve both are controlled to be powered on.
In an embodiment of the present disclosure, in response to the operation mode of the air conditioner being the heating mode, the first four-way valve 151 and the second four-way valve 152 both are controlled to be powered on.
As shown in

In other words, when the operation mode of the air conditioner is changed from the heating mode to the defrosting mode, the outdoor heat exchanger 11 is converted from serving as the evaporator to serving as the condenser, the indoor heat exchanger 12 continues serving as the condenser, and the heat storage heat exchanger 13 is converted from serving as the condenser to serving the evaporator, and the heat is absorbed from the heat storage heat exchanger 13 for defrosting the outdoor heat exchanger 11 without adversely affecting the heating performance of the indoor heat exchanger 12, to improve the air conditioner for comfort and user's experience.
Summing up the above, according to embodiments of the present disclosure, the method for controlling the air conditioner identifies the operation mode of the air conditioner; controls the first four-way valve and the second four-way valve both to be powered on in response to the operation mode of the air conditioner being the heating mode; and controls the first four-way valve to be powered off and the second four-way valve to be powered on in response to the operation mode of the air conditioner being the defrosting mode. Accordingly, when the operation mode of the air conditioner is the defrosting mode, the outdoor heat exchanger and the indoor heat exchanger each serve as the condenser, while the heat storage heat exchanger serves as the evaporator, and heat is absorbed from the heat storage heat exchanger for defrosting the outdoor heat exchanger without adversely affecting the heating performance of the indoor heat exchanger, to improve the air conditioner for comfort and user's experience.
On the basis of any of the above embodiments, after controlling the first four-way valve to be powered off and the second four-way valve to be powered on at S103, the method further includes: controlling the first four-way valve and the second four-way valve both to be powered on, in response to identifying that the outdoor heat exchanger is of a first pipe-wall temperature higher than or equal to a first preset temperature and/or that a defrosting duration reaches a first preset duration.
It would be appreciated that identifying that the outdoor heat exchanger is of the first pipe-wall temperature higher than or equal to the first preset temperature and/or that the defrosting duration reaches the first preset duration indicates that the first pipe-wall temperature of the outdoor heat exchanger is relative high and/or that the defrosting duration is relative long at this time. Accordingly, it is determined that a criteria to finish defrosting is met in this circumstance, thus the first four-way valve and the second four-way valve both are controlled to be powered on, enabling the operation mode of the air conditioner to change from the defrosting mode to the heating mode.
The first preset temperature and the first preset duration each may be set according to an actual situation. For example, the first preset temperature may be set as 15° C. and the first preset duration may be set as 10 minutes.
On the basis of any of the above embodiments, as shown in
At S201, it is determined whether the air conditioner is in a target operation state, where the target operation state includes a heating target operation state and a cooling target operation state.
In an embodiment of the present disclosure, it is further determined whether the air conditioner is in the target operation state, where the target operation state includes the heating target operation state and the cooling target operation state. It should note that the target operation state refers to an operation state under a low load.
In one embodiment, determining whether the air conditioner is in the target operation state may include the following two possible implementing approaches.
Approach 1, in response to identifying that the air conditioner is of a heating capacity demand parameter (Nh) or a cooling capacity demand parameter (Nc) lower than or equal to a first preset threshold for a second preset duration, it is determined that the air conditioner is in the target operation state; or in response to identifying that the air conditioner is of a heating capacity demand parameter or a cooling capacity demand parameter greater than or equal to a second preset threshold for a third preset duration, it is determined that the air conditioner is not in the target operation state.
It would be appreciated that the heating capacity demand parameter or the cooling capacity demand parameter of the air conditioner may be used to characterize a load of the air conditioner. The smaller the heating capacity demand parameter or the cooling capacity demand parameter of the air conditioner, the lower the load of the air conditioner.
Identifying that the air conditioner is of the heating capacity demand parameter or the cooling capacity demand parameter lower than or equal to the first preset threshold for the second preset duration indicates that the heating capacity demand parameter or the cooling capacity demand parameter of the air conditioner is relative low for a relative long time period at this time. Accordingly, it is determined that the air conditioner is in the target operation state.
In one embodiment, identifying that the air conditioner is of the heating capacity demand parameter or the cooling capacity demand parameter greater than or equal to the second preset threshold for the third preset duration indicates that the heating capacity demand parameter or the cooling capacity demand parameter of the air conditioner is relative high for a relative long time period at this time. Accordingly, it is determined that the air conditioner is out of the target operation state.
The first preset threshold, the second preset threshold, the second preset duration, and the third preset duration each may be set according to an actual situation, which is not further limited here.
Approach 2, in the case that the air conditioner includes the indoor heat exchangers, based on that the operation mode of the air conditioner is a mixed mode, where the mixed mode includes the heating mode for at least one of the indoor heat exchangers and a cooling mode for at least one of the indoor heat exchangers, a heating capacity demand parameter and a cooling capacity demand parameter are acquired; and in response to identifying that the heating capacity demand parameter is lower than or equal to the cooling capacity demand parameter, it is determined that the air conditioner is in the heating target operation state; in one embodiment, in response to identifying that the heating capacity demand parameter is greater than the cooling capacity demand parameter, it is determined that the air conditioner is in the cooling target operation state.
Taking
In an embodiment of the present disclosure, in the case that the air conditioner includes the indoor heat exchangers, in response to the operation mode of the air conditioner being the mixed mode, where the mixed mode includes the heating mode for at least one of the indoor heat exchangers and the cooling mode for at least one of the indoor heat exchangers, in this circumstance, acquiring the heating capacity demand parameter may include acquiring the heating capacity demand parameter of the indoor heat exchanger in the operation mode being the heating mode; and accordingly, acquiring the cooling capacity demand parameter may include acquiring the cooling capacity demand parameter of the indoor heat exchanger in the operation mode being the cooling mode.
Further, it is identified a relationship between the heating capacity demand parameter and the cooling capacity demand parameter, where identifying that the heating capacity demand parameter is lower than or equal to the cooling capacity demand parameter indicates that the heating capacity demand parameter is relative low, and it is then determined that the air conditioner is in the heating target operation state; in one embodiment, identifying that the heating capacity demand parameter is greater than the cooling capacity demand parameter indicates that the cooling capacity demand parameter is relative low, and it is then determined that the air conditioner is in the cooling target operation state.
At S202, in response to the air conditioner being in the target operation state, the throttling assembly is controlled to switch on; or in response to the air conditioner being out of the target operation state, the throttling assembly is controlled to switch off.
In an embodiment of the present disclosure, in response to the air conditioner being in the target operation state, the throttling assembly is controlled to switch on, enabling the bypass to be connected, allowing the refrigerant to enter the heat storage heat exchanger, and the heat storage heat exchanger is used to store heat in this circumstance, to adjust the load of the air conditioner by the heat storage heat exchanger, assisting in avoiding the air conditioner from being in the operation state under the low load for a long time period, thus improving operation reliability of the air conditioner.
In one embodiment, in response to the air conditioner being out of the target operation state, the throttling assembly is controlled to switch off, enabling the bypass to be disconnected, and the refrigerant cannot enter the heat storage heat exchanger and thus the heat storage heat exchanger is not used to store heat in this circumstance. Accordingly, the load of the air conditioner cannot be adjusted by the heat storage heat exchanger in this circumstance
Therefore, the method controls the throttling assembly to switch on or off according to whether the air conditioner is in the target operation state. When the air conditioner is in the target operation state, the throttling assembly is controlled to switch on, to adjust the load of the air conditioner by the heat storage heat exchanger, assisting in avoiding the air conditioner from being in the operation state under the low load for a long time period, thus improving operation reliability of the air conditioner.

The second preset temperature and the fourth preset duration each may be set according to an actual situation. For example, the second preset temperature may be set as 58° C. and the fourth preset duration may be set as 8 minutes.
At S305, in response to identifying that the heat storage heat exchanger is of an outlet pipe-wall temperature greater than or equal to a fourth preset temperature for a sixth preset duration, the first four-way valve is controlled to be powered off.
