Be described in detail below in conjunction with the implementation procedure of example inventive embodiments.
Fig. 3 is the flow chart according to the processing method of the air conditioner refrigerant of the embodiment of the invention one.
In the present embodiment, indoor set 10 is connected to form loop with off-premises station 40 by tracheae tube connector 20 and liquid pipe connected pipe 30, be provided with the big valve 41 and the minor valve 42 that are used to take on the off-premises station, wherein big valve 41 is connected with tracheae tube connector 20 1 ends, and minor valve 42 is connected with liquid pipe connected pipe 30 1 ends.Before big valve 41, first magnetic valve 43 is being set, and second magnetic valve 431 is being set before the minor valve 42.
As shown in Figure 3, this method comprises the steps:
Step S301 receives off signal.Air-conditioner receives off signal, and off signal comprises normal shutdown and abnormal shutdown.
Step S302 judges running state of air conditioner.
Step S303 judges whether the running status of air-conditioning is the refrigerating operaton state, execution in step S304 under refrigerating state, otherwise, change step S307 over to.
Step S304 closes second stop valve 431.
Under refrigerating state, air-conditioner receives off signal in the present embodiment, and controller controls second magnetic valve 431 and cuts out, and cuts off the passage that the off-premises station cold-producing medium enters indoor set, and indoor cold-producing medium still can reclaim into off-premises station through big valve simultaneously,
Step S305 judges time delay.By timer be set the scheduled time, judge whether delay time arrives the scheduled time.When delay time arrives the scheduled time, execution in step S306, otherwise continue execution in step S305.
In the embodiment of the invention, through the certain time-delay time (different concrete fixed according to the type refrigerating capacity, to the 1P machine time about 10 seconds; 1.5P about 12 seconds of air-conditioning; More than 2P reaches, about 15 seconds), this moment, indoor pusher side cold-producing medium almost entered off-premises station all.
Step S306 closes first stop valve 43.After indoor pusher side cold-producing medium almost enters off-premises station all, close first magnetic valve 43 this moment again, air-conditioner is controlled the complete machine shutdown again.
The embodiment of the invention has realized the closing sequence of two magnetic valves of control when air-conditioner shuts down, and cold-producing medium all is enclosed in the outside.After two closed electromagnetic valves of air-conditioner, air conditioner is carried out the complete machine shutdown, and shutdown process successfully finishes.
Step S307, control air-conditioning transformation of ownership cold operation.When the running status of air-conditioning was the heating operation state, controller control air-conditioner transferred the refrigerating operaton state to.
Heat under the state in the present embodiment, air-conditioner receives off signal, and controller control air-conditioning transfers refrigerating operaton to, then closes second stop valve 431, certain scheduled time of process is closed first stop valve 43, last complete machine shutdown (the same refrigerating state of the control mode behind the transformation of ownership cold operation).
Fig. 4 is the flow chart according to the processing method of the air conditioner refrigerant of the embodiment of the invention two.
As shown in Figure 4, this method comprises the steps:
Step S401 to step S404 with step S301 to step S304, wherein, among the step S403, execution in step S404 under refrigerating state, otherwise, change step S407 over to.
Step S405, whether the force value that detects first stop valve, 43 places is zero.Execution in step S406 when force value is 0, otherwise, execution in step S405 continued.
In the present embodiment, on first stop valve 43, increase a pressure-detecting device.Under the refrigerating state, air-conditioner receives off signal, controls second magnetic valve 431 and closes, and treats that it is 0 that pressure-detecting device on first stop valve 43 detects pressure, then controls first stop valve 43 and closes.
Step S406 is with step S306.
Step S407, control air-conditioning transformation of ownership cold operation.
Heat under the state in the present embodiment, air-conditioner receives off signal, control air-conditioning transformation of ownership cold operation, then close second stop valve 431, treat that it is 0 that pressure-detecting device on first stop valve 43 detects pressure, then control first stop valve 43 and close, last complete machine shutdown (the same refrigerating state of the control mode behind the transformation of ownership cold operation).
From above description, as can be seen, the above embodiments of the present invention have realized following technique effect: by adopting the technical scheme of the foregoing description, during the air-conditioner shutdown, through the processing of technical scheme, the indoor refrigerant is reclaimed, can be with at least 95% refrigerant-recovery to the outside, the residual cold-producing medium in indoor was not very little when air-conditioner was not worked, and reached the purpose of expectation.
Need to prove, can in computer system, carry out in the step shown in the flow chart of accompanying drawing such as a set of computer-executable instructions, and, though there is shown logical order in flow process, but in some cases, can carry out step shown or that describe with the order that is different from herein.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
