Fig. 2 is the flow chart for being applied to the refrigerant transfer device 100 shown in Fig. 1 that present pre-ferred embodiments provide, under
It is described in detail in face of the idiographic flow shown in Fig. 2.
Step S101, obtain the identity information of the outer machine module of at least one failure.
Modular multi-connection formula air-conditioning is combined for the outer machine of several Large Copacities, so as to drive more interior machine system
A kind of cold or heating large-scale refrigeration plant., need to be to machine outside failure when one or more outer machine module breaks down
Module is repaired.In the present embodiment, in order to refrigerant will not be made to be discharged into air in maintenance process, cause environmental pollution with
And increase maintenance cost, the refrigerant outside failure in machine module need to be discharged into normal outer machine module.
In order to achieve the above object, the outer machine module of failure need to be determined first.In the present embodiment, can be by server 10 certainly
It is dynamic to utilize correlation data calculation during operation of air conditioner to go out whether outdoor machine of air-conditioner breaks down, it can be also manually entered by staff
The mode of the identity information of the outer machine module of failure determines the outer machine module of failure.It should be noted that in the present embodiment, identity letter
Cease to the numbering of each outer machine module, but in some other embodiments, identity information can also be other information, this implementation
Example does not do any restriction to this.
Step S102, obtain the quantity information of the outer machine module of the failure.
Because the outer machine module to be broken down in actual moving process may be more than one, so first need to obtain outside failure
The quantity information of machine module.In the present embodiment, server 10 can be directly according to the identity information of machine module outside the failure of acquisition
The quantity information of the outer machine module of failure judgement.For example, the identity information of machine module outside a failure is obtained when server 10 connects,
Then can determine whether the to be out of order quantity information of outer machine module of server 10 is 1.
Step S103, judges whether the quantity information of the outer machine module of the failure is less than presetting quantity information, if
It is then to perform step S104, if it is not, then terminating.
Because the refrigerant transfer method that the present embodiment provides is to be discharged into all refrigerants in machine module outside failure normally
In outer machine module, so needing to judge whether that all outer machine modules break down first, if it is, terminating flow, work people
Member directly repairs to all outer machine modules, if it is not, then performing next step.In the present embodiment, presetting number
The quantity information that information is outer machine module is measured, for example, a total of 4 outer machine modules of the air-conditioning equipment, then presetting quantity is believed
Breath is 4.
Step S104, the quantity information according to machine module outside the failure reduce the power of indoor set.
After one or more outer machine modules break down wherein, drive indoor set work be mainly it is remaining just
Normal outer machine module.And the maximum load of each outer machine module is constant, can be driven most when load has exceeded normal outer machine module
Big load, then it is likely to occur the appearance for the situation that remaining normal outer machine module can not drive indoor set to work.For example, before
Indoor set is driven to be operated by 4 outer machine modules, after an outer machine module breaks down wherein, then mainly by remaining 3
Individual normal outer machine module drive indoor set is operated, if now the power of indoor set has exceeded 3 normal outer machine modules
Maximum load, then the situation that 3 normal outer machine modules can not drive indoor set to work occurs.
In view of this, in the present embodiment, it is necessary to according to outside failure machine module quantity information reduce indoor set power,
So that remaining normal outer machine module can drive indoor set to be operated.In the present embodiment, indoor set is proportionally reduced
Power.For example, when there is 1 outer machine module to break down in 4 outer machine modules, then remaining normal outer machine module can provide
Energy be original 75%, so the power of 25% indoor set need to be reduced.Of course, in some other embodiments,
Also the power of indoor set can be reduced otherwise, and the present embodiment does not do any restriction to this.
Step S105, the aperture of liquid matchmaker's valve of the normal outer machine module is down to the first presetting position.
In the present embodiment, the refrigerant in machine module outside failure is drained into normal outer machine module in order to realize, needs to control
The outer machine module of failure processed is in heating state, and normal outer machine module is in refrigerating state.
Here, it should be noted that the refrigerant valve of all outer machine modules includes liquid matchmaker valve and gas matchmaker's valve, its
In, when outer machine module is in refrigerating state, refrigerant flows out from liquid matchmaker valve, while is flowed into from gas matchmaker valve；When outer machine module
During in heating state, refrigerant flow direction with refrigerant flow direction during refrigerating state on the contrary, refrigerant flows into from liquid matchmaker valve, while from gas
Matchmaker's valve is flowed out, and refrigerant can be had gaseous compressed into liquid by compressor.
And it is further desired that explanation, in whole module multi-online air-conditioning system, high pressure main liquid tube is connection, always
Tracheae is also connection, i.e., all outer machine modules and indoor set form an annular, refrigerant circulation in this toroidal system, profit
With the continuous change of refrigerant state, refrigeration or the effect of heating are realized.
Because the purpose of the present embodiment is that the refrigerant of machine module outside failure is transferred into normal outer machine module, so needing to the greatest extent
Refrigerant is flowed into normal outer machine module possible more, meanwhile, refrigerant outflow as few as possible normally outer machine module is controlled, with this
Refrigerant is set to be transferred in normal outer machine module.In view of this, in the present embodiment, refrigerant is transferred to more quickly in order to realize
In normal outer machine module, the aperture of liquid matchmaker's valve of normal outer machine module need to be reduced, while keep the gas of normal outer machine module
Matchmaker's valve is opened completely.When being in refrigerating state in normal outer machine module, refrigerant is flowed out by liquid matchmaker valve, while by gas matchmaker's valve
Door flows into, and passes through above-mentioned control mode, it is possible to achieve the amount for flowing into the refrigerant of normal outer machine module does not change, but flows out normal
The amount of the refrigerant of outer machine module is greatly lowered, and the effect that refrigerant is transferred in normal outer machine module is realized with this.
It should be noted that in the present embodiment, due in the course of the work when, refrigerant needs not stop to circulate, so that whole
Individual operation of air conditioner, if now completely closing liquid matchmaker's valve of normal outer machine module, the compressor of normal outer machine module can be caused
Damage.Study and find through inventor, can be by normal outer machine module on the premise of ensureing that normal outer machine compressor does not damage
Liquid matchmaker's valve is closed to 1/3rd state.In view of this, in the present embodiment, the first presetting position as will be normally outer
Machine module is closed to 1/3rd position, i.e., the current amount for flowing out the refrigerant in normal outer machine module is only to flow out before normally
/ 3rd of the amount of refrigerant in outer machine module.
It is also desirable to explanation, in the present embodiment, the aperture of liquid matchmaker's valve is automatically controlled using server 10
Mode realizes control, but in some other embodiments, also can be by setting manually-operated gate, by staff's manual modulation valve
The mode of door is controlled, and the present embodiment does not do any restriction to this.
Step S106, the aperture of liquid matchmaker's valve of machine module outside the failure is down to the second presetting position.
It is similar with step S105, because machine module can be controlled as heating mode and be operated outside failure, so its refrigerant
Flow direction and the refrigerant of normal outer machine module flow direction on the contrary, i.e. refrigerant is flowed into by liquid matchmaker valve, by the outflow of gas matchmaker valve.In order to
Realize that, by machine module outside refrigerant discharge failure as fast as possible, the liquid matchmaker valve of the outer machine module of the present embodiment control failure, which reduces, to be opened
Degree, so that refrigerant keeps constant by the amount flowed out in machine module outside failure, when the amount for flowing into the refrigerant outside failure in machine module is big
Amplitude reduces, so as to which the refrigerant in machine module outside failure gradually be discharged.
It should be noted that in the present embodiment, the second presetting position is also by liquid matchmaker's valve of machine module outside failure
Close to 1/3rd position.
It is also desirable to explanation, in the present embodiment, step S102- steps S104, step S105 and step
S106 has no sequencing.
Step S107, the four-way valve for controlling the outer machine module of each failure to include are in power-up state, and except described
The four-way valve of normal outer machine module outside the outer machine module of failure is in power-down state.
When needing the refrigerant in machine module outside failure to be transferred in normal outer machine module, need to control the outer machine module of failure
In heating state, while normal outer machine module is controlled to be in refrigerating state.In the present embodiment, by controlling outer machine module
Four-way valve is in different states, so as to control outer machine module to be in different working conditions.The meeting of server 10 in the present embodiment
The four-way valve of the outer machine module of control failure works when being in power-up state, as heating mode, and controls normal outer machine module
Four-way valve is in power-down state work, as refrigeration mode.So the tracheae of the outer machine module of failure is high-pressure side, and normal outer machine
The tracheae of module is low-pressure side.The outer machine inside modules refrigerant of failure can eject slowly in running, and normal outer machine module meeting
Refrigerant is slowly reclaimed, it is achieved thereby that the transfer of refrigerant.
It should be noted that because the part in the present embodiment, the outer machine module of failure has had damage, so should reduce
The ability to work (i.e. the working frequency of the outer machine module of failure) of the outer machine module of the failure, is further damaged with machine module outside fail-safe
It is bad, cause more difficult in maintenance.In view of this, in practical work process, the work frequency of the outer machine module of failure should be reduced
The working frequency of machine module outside failure is down to the 25% of original working frequency by rate, the present embodiment, of course, some other
In embodiment, working frequency can be also down to other numerical value, the present embodiment does not do any restriction to this.
It should also be noted that, in the present embodiment, step S105, step S106 and step S107 is without successively suitable
Sequence.
Step S108, liquid matchmaker's valve of machine module outside the failure is controlled to completely close after the presetting time.
Machine module is in heating state outside by failure, and normal outer machine pattern is in refrigerating state and worked after a period of time,
Refrigerant in the outer machine module of failure can be gradually discharged into normal outer machine module, i.e., after a period of operation, the outer machine module of failure
In refrigerant almost all discharges, in order that the refrigerant in the outer machine module of failure is all discharged, the outer machine module of failure need to be made
In liquid matchmaker's valve completely close, ensure that refrigerant can not be discharged into the outer machine module of failure, the used time is due to air-conditioning also in work
State, so the refrigerant in the outer machine module of failure can also be discharged by gas matchmaker valve.
It should be noted that because after a period of operation, the refrigerant in the outer machine module of failure is substantially drained, so
, can be by the refrigerant in machine module outside failure within the extremely short time after liquid matchmaker's valve of machine module outside failure is completely closed
It is completely exhausted out, so externally machine module will not cause further to damage.Tested through inventor, it is in the present embodiment, presetting
Time be 3min, of course, in other embodiments, can also have more actual conditions and different preheating setting time is set.
The another way realized as the present embodiment, also can be by way of measuring the pressure value outside failure in machine module
Liquid matchmaker's valve of the outer machine module of control failure completely closes.For example, when pressure value is less than or equal to 1Kg, that is, represent the outer machine of failure
Refrigerant in module is completely expelled, i.e., when pressure value is equal to 1.1Kg, represents that refrigerant is soon discharged completely, now control event
Liquid matchmaker's valve of the outer machine module of barrier completely closes.
Step S109, gather the internal pressure value of the outer machine module of each failure.
Step S110, judges whether the pressure value of the outer machine module of each failure is respectively less than or equal to presetting pressure
Value, if it is, performing step S111, if fruit is no, returns and perform step S107.
In the present embodiment, by whether judging to hinder the internal pressure value of outer machine module in or equal to presetting pressure value
Mode, judge whether the refrigerant in the outer machine module of each failure is completely expelled.Because the pressure in outer machine module can be with
The reduction of the amount of refrigerant and reduce, so when being reduced to extreme value, that is, represent that refrigerant is completely expelled.In the present embodiment, in advance
The pressure value set is 1kg, but in some other embodiments, due to the difference of the specification of outer machine module, so presetting
Pressure value it is also different, the present embodiment does not do any restriction to this.
Step S111, close the refrigerant valve that the outer machine of the failure includes, and control the outer machine module of the failure with it is described
Normal outer machine module from service.
When whether the pressure value of machine module outside each failure is respectively less than or equal to presetting pressure value, that is, represents event
Refrigerant in the outer machine module of barrier is all discharged, now needs to stop machine module outside control failure and the normal outer machine module
Work, so that the outer machine of staff's degree failure is repaired.
