Embodiment
The embodiment of the embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this
The embodiment of place description is merely to illustrate and explain the present invention embodiment, is not intended to limit the invention embodiment.
Fig. 1 is the flow chart for the air conditioner system control method that one embodiment of the invention is provided.As shown in figure 1, the present invention is real
Apply example and a kind of air conditioner system control method is provided, the air-conditioning includes outer machine and the interior machine being connected with the outer machine, and this method includes：
When the outer machine is shut down, it is determined that causing the reason for outer machine is shut down (step S101)；According to causing what the outer machine was shut down
Reason, controls the power on/off (step S102) of the four-way valve of the outer machine.
When outer machine is shut down, the reason for judgement causes outer machine to be shut down is that artificial shutdown, failure or interior reach predetermined temperature
Different Deng, the reason for being shut down according to outer machine, the four-way valve of external machine performs different control system of switching on or off electricity, and specific control mode is as follows
Text is described in detail.
Fig. 2 is the flow chart for the air conditioner system control method that another embodiment of the present invention is provided.As shown in Fig. 2 this method
Including：When the outer machine is shut down, it is determined that causing the reason for outer machine is shut down (step S201)；Reached in the interior machine predetermined
When temperature causes the outer machine shutdown, the four-way valve of the outer machine is controlled to remain powered on (step S202).
When outer machine is shut down, system can be judged, if when interior machine reaches that predetermined temperature causes outer function shutdown,
Mean that and run again when outer machine will also wait indoor temperature departure predetermined temperature, the time started twice will not be too
Long, so compressor is just always maintained at "on" position.
Fig. 3 is the flow chart for the air conditioner system control method that another embodiment of the present invention is provided.As shown in figure 3, this method
Including：When the outer machine is shut down, it is determined that causing the reason for outer machine is shut down (step S301)；In artificial shutdown or fail close
