At this time, the indoor units in other rooms are often in a standby state or an off state. But the heat generated in the heating room is gradually transferred to the rest of the room due to the propagation of the walls and the air medium. In order to recover the waste heat, the related art proposes a defrosting control method including: acquiring the current running state and the accumulated running time of the inner fan; judging the room state of the inner fan according to the current running state and the accumulated running time of the inner fan; the room state of the inner fan comprises a normal use room, a common room and an unusual room; and determining the opening degree of the electronic expansion valve and/or the running parameters of the inner fan according to the room state of the inner fan.
The related art focuses on using idle heat during the defrosting stage to shorten the defrosting cycle. However, in the normal heating process of the air conditioner, the waste heat recovery function cannot be exerted.

By adopting the method for controlling the multi-split air conditioning system, which is provided by the embodiment of the invention, the working or idle conditions of the indoor units in different rooms can be better judged by monitoring the running states of the indoor units. Through monitoring the ambient temperature in the room that idle indoor set was located, this disclosed embodiment can screen out the indoor set that accords with waste heat recovery condition to control it and carry out refrigeration operation, in order to carry out recycle to the inside heat of room that is located.

Therefore, the working efficiency of the indoor unit can be further improved under the condition of ensuring the normal operation of the indoor unit.
Optionally, the processor adjusts the rotation speed of the inner fan and/or the opening of the electronic expansion valve of the non-running indoor unit according to the outdoor environment temperature, including: when the outdoor environment temperature is higher than the first outdoor preset temperature, the processor adjusts the rotating speed of the inner fan of the non-operating indoor unit to be the first rotating speed, and/or adjusts the opening of the electronic expansion valve of the non-operating indoor unit to be the first opening; when the outdoor environment temperature is smaller than or equal to the first outdoor preset temperature and larger than the second outdoor preset temperature, the processor adjusts the rotating speed of the inner fan of the non-operating indoor unit to be the second rotating speed, and/or adjusts the opening of the electronic expansion valve of the non-operating indoor unit to be the second opening; and when the outdoor environment temperature is less than or equal to the second outdoor preset temperature, the processor adjusts the rotating speed of the inner fan of the non-operating indoor unit to be a third rotating speed, and/or adjusts the opening of the electronic expansion valve of the non-operating indoor unit to be a third opening. Thus, based on different outdoor environment temperatures, the embodiment of the disclosure can control the inner fan and/or the electronic expansion valve to execute different functional adjustments so as to realize accurate adjustment of the refrigerating capacity of the indoor unit in unit time. The embodiment of the disclosure can more reasonably distribute the indoor and outdoor unit refrigerating capacity because the difference of the working conditions of the outdoor unit is fully considered. Is favorable for delaying the arrival of the defrosting stage of the outdoor unit.
Specifically, the first outdoor preset temperature is a critical environment temperature at which the outdoor unit heat exchanger starts to frost under the heating mode of the multi-split air conditioning system. In some embodiments, the first outdoor preset temperature may be set to 15 ℃. Under the condition that the multi-split air conditioning system is in a heating mode, the outdoor unit heat exchanger plays a role of an evaporator and can continuously absorb heat from the external environment. If the outdoor ambient temperature is lower than the first outdoor preset temperature, the temperature around the outdoor unit gradually decreases to the frost critical temperature due to the heat absorption process of the evaporator. After a period of time, the outdoor heat exchanger starts to frost, and the working efficiency of the heat exchanger is further affected.
Specifically, the second outdoor preset temperature is a critical ambient temperature at which the outdoor heat exchanger starts to frost when the multi-split air conditioning system is in a standby mode. In some embodiments, the second outdoor preset temperature may be set to 1 ℃. If the outdoor ambient temperature is lower than the second outdoor preset temperature, the outdoor heat exchanger starts to frost due to the fact that the ambient temperature is too low, and therefore the working efficiency of the heat exchanger is affected.
Alternatively, the first outdoor preset temperature and the second outdoor preset temperature may be adjusted according to specific outdoor environment information. But it should be noted that the first outdoor preset temperature should be greater than the second outdoor preset temperature. For example, in case of combining the outdoor environment humidity, the first outdoor preset temperature may be adjusted to 16 ℃ and the second outdoor preset temperature may be adjusted to 2 ℃.
Optionally, the first rotational speed is less than the second rotational speed, and the second rotational speed is less than the third rotational speed. Preferably, the first rotational speed is a low wind speed gear, the second rotational speed is a medium wind speed gear, and the third rotational speed is a high wind speed gear. Thus, if the outdoor unit is in a working environment with higher outdoor temperature, the heat exchanger of the outdoor unit is not easy to frost even if the multi-split air conditioning system is in a heating mode. Therefore, the embodiment of the disclosure can adaptively reduce the rotation speed of the inner fan of the indoor unit which is not operated so as to reduce the refrigeration capacity required to be born by the indoor unit, thereby being beneficial to reducing the possibility of frosting of the heat exchanger of the indoor unit. If the outdoor unit is in a working environment with lower outdoor temperature, the heat exchanger of the outdoor unit can generate frosting phenomenon when the multi-split air conditioning system is in a heating mode. At this time, the embodiment of the disclosure slightly increases the rotation speed of the inner fan of the non-running indoor unit, so as to utilize the idle indoor unit to share the refrigeration capacity of the outdoor unit, thereby reducing the frosting speed of the heat exchanger of the outdoor unit, and being beneficial to delaying the arrival of the defrosting stage. And if the outdoor unit is in the working environment with extremely low outdoor temperature, no matter the multi-split air conditioning system is in a heating mode or a standby mode, the outdoor unit heat exchanger can generate frosting. Therefore, in the embodiment of the disclosure, the inner fan needs to be rotated and adjusted to the maximum so as to reduce the refrigeration capacity required to be born by the outdoor unit as much as possible, thereby avoiding the phenomenon that the frosting degree of the heat exchanger of the outdoor unit is rapidly increased and the heating process is affected.
Optionally, the first opening is smaller than the second opening, and the second opening is smaller than the third opening. Preferably, the first opening is a small opening gear, the second opening is a medium opening gear, and the third opening is a large wind speed gear. Thus, if the outdoor unit is in a working environment with higher outdoor temperature, the heat exchanger of the outdoor unit is not easy to frost even if the multi-split air conditioning system is in a heating mode. Therefore, the embodiment of the disclosure can adaptively reduce the opening of the electronic expansion valve of the indoor unit which is not operated so as to reduce the refrigeration capacity required to be born by the indoor unit, thereby being beneficial to reducing the possibility of frosting of the heat exchanger of the indoor unit. If the outdoor unit is in a working environment with lower outdoor temperature, the heat exchanger of the outdoor unit can generate frosting phenomenon when the multi-split air conditioning system is in a heating mode. At this time, the embodiment of the disclosure slightly increases the opening of the electronic expansion valve of the non-operating indoor unit, so as to share the refrigerating capacity of the outdoor unit by using the idle indoor unit, thereby reducing the frosting speed of the heat exchanger of the outdoor unit, and being beneficial to delaying the arrival of the defrosting stage. And if the outdoor unit is in the working environment with extremely low outdoor temperature, no matter the multi-split air conditioning system is in a heating mode or a standby mode, the outdoor unit heat exchanger can generate frosting. Therefore, in the embodiment of the disclosure, the opening of the electronic expansion valve needs to be adjusted to the maximum so as to reduce the refrigeration capacity required to be born by the outdoor unit as much as possible, thereby avoiding the phenomenon that the frosting degree of the heat exchanger of the outdoor unit is rapidly increased, and the heating process is affected.

Meanwhile, by adding the idle indoor units to the multi-split air conditioning system to execute refrigeration operation, the embodiment of the disclosure can effectively share the refrigeration capacity of the outdoor unit, so that the heat required to be absorbed from the outside by the outdoor unit can be reduced. By combining the monitoring of the working environment of the outdoor unit and the temperature of the coil pipe of the heat exchanger of the outdoor unit, the embodiment of the disclosure can more accurately adjust the operation parameters of the indoor unit so as to realize reasonable distribution of indoor and outdoor refrigeration capacity. Therefore, the frosting speed of the heat exchanger of the outdoor unit can be further reduced, and the arrival of the defrosting stage is facilitated to be delayed.
Alternatively, the method for controlling the multi-split air conditioning system may be performed in the multi-split air conditioning system, or may be performed in a server in communication with the multi-split air conditioning system.

Therefore, through monitoring the temperature of the coil pipe of the heat exchanger of the outdoor unit, the embodiment of the disclosure can more accurately judge the frosting condition of the outdoor unit, thereby reasonably adjusting the operation parameters of the indoor unit and realizing the reasonable distribution of indoor and outdoor refrigeration capacity. Especially, under the condition that the coil pipe of the heat exchanger of the outdoor unit is extremely low and the frosting phenomenon of the heat exchanger is easy to occur, the working parameters of the indoor unit can be increased to further share the refrigerating capacity of the outdoor unit. Therefore, the frosting speed of the heat exchanger of the outdoor unit can be reduced, and the arrival of a defrosting stage is facilitated to be delayed.
Specifically, the preset temperature of the second coil is the critical coil temperature of the outdoor heat exchanger, which is easy to frost. In some embodiments, the second coil preset temperature may be set at-2 ℃. If the temperature of the coil of the heat exchanger of the outdoor unit is lower than the preset temperature of the second coil, the heat exchanger of the outdoor unit can rapidly start to frost due to the fact that the temperature of the actual coil is too low, and therefore the working efficiency of the heat exchanger is affected.
