Fig. 2 is the flow chart applied to refrigerant transfer device 100 shown in FIG. 1 that present pre-ferred embodiments provide, under
It is described in detail in face of detailed process shown in Fig. 2.
Step S101 obtains the identity information of the outer machine module of at least one failure.
Modular multi-connection formula air-conditioning is that the outer machine of several large capacities is combined, to drive more interior machine system
A kind of cold or heating large-scale refrigeration equipment.It, need to be to machine outside failure when one or more outer machine module breaks down
Module repairs.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.It in the present embodiment, can be by server 10 certainly
It is dynamic that correlation data calculation when operation of air conditioner is utilized to go out whether outdoor machine of air-conditioner breaks down, it can also be 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
It ceases to the number of each outer machine module, but in other some embodiments, identity information may be other information, this implementation
Example does not do any restriction to this.
Step S102 obtains the quantity information of the outer machine module of the failure.
Since the outer machine module to break down in actual moving process may be one more than, so need to first 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
Judge the quantity information of the outer machine module of failure.For example, working as server 10 connects the identity information for obtaining the outer machine module of a failure,
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 to then follow the steps S104, if it is not, then terminating.
Since refrigerant transfer method provided in this embodiment is to be discharged into all refrigerants outside failure in machine module normally
In outer machine module, so needing to judge whether that all outer machine modules break down first, if it is, terminating process, work people
Member directly repairs all outer machine modules, if it is not, then performing the next step rapid.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 reduces the power of indoor unit according to the quantity information of machine module outside the failure.
After one or more outer machine modules break down wherein, drive indoor unit work be mainly it is remaining just
Normal outer machine module.And the maximum load of each outer machine module is constant, when load has been more than that normal outer machine module is able to drive most
Big load is then likely to occur the appearance for the case where remaining normal outer machine module is unable to drive indoor unit work.For example, before
Indoor unit is driven to work by 4 outer machine modules, after an outer machine module breaks down wherein, then mainly by remaining 3
A normal outer machine module drives indoor unit to work, if the power of indoor unit has been more than 3 normal outer machine modules at this time
Maximum load then will appear the case where 3 normal outer machine modules are unable to drive indoor unit work.
In view of this, in the present embodiment, need to reduce the power of indoor unit according to the quantity information of machine module outside failure,
So that remaining normal outer machine module is able to drive indoor unit and works.In the present embodiment, indoor unit is proportionally reduced
Power.For example, then remaining normal outer machine module is capable of providing when there is the failure of 1 outer machine module in 4 outer machine modules
Energy be original 75%, so the power of 25% indoor unit need to be reduced.Of course, in some other embodiments,
The power of indoor unit can also be reduced otherwise, and the present embodiment does not do any restriction to this.
The aperture of liquid matchmaker's valve of the normal outer machine module is down to the first presetting position by step S105.
In the present embodiment, the refrigerant outside failure in machine module 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.
Herein, it should be noted that the refrigerant valve of all outer machine modules includes liquid matchmaker valve and gas matchmaker valve,
In, when outer machine module is in refrigerating state, refrigerant is flowed out from liquid matchmaker's valve, while being flowed into from gas matchmaker's valve；When outer machine module
When in heating state, refrigerant flow direction when refrigerant flow direction is with refrigerating state is on the contrary, refrigerant is flowed into from liquid matchmaker's valve, while from gas
Refrigerant can be had gaseous compressed at liquid by the outflow of matchmaker's valve, compressor.
And it is further desired that explanation, in entire 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 unit constitute an annular, refrigerant circulation in this toroidal system, benefit
With the continuous change of refrigerant state, the effect of refrigeration or heating is realized.
Since the purpose of the present embodiment is that the refrigerant of machine module outside failure is transferred to normal outer machine module, so needing to the greatest extent
Flowing into refrigerant in normal outer machine module possible more, meanwhile, refrigerant outflow as few as possible normally outer machine module is controlled, with this
It is transferred to refrigerant 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 keeping the gas of normal outer machine module
Matchmaker's valve fully opens.When being in refrigerating state in normal outer machine module, refrigerant is flowed out by liquid matchmaker's valve, while by gas matchmaker's valve
Door flows into, and by above-mentioned control mode, the amount that may be implemented to flow 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 realizes the effect that refrigerant is transferred in normal outer machine module with this.
It should be noted that in the present embodiment, due to during the work time when, refrigerant needs not stop to recycle, so that whole
A operation of air conditioner will lead to the compressor of normal outer machine module if completely closing liquid matchmaker's valve of normal outer machine module at this time
Damage.It, can be by normal outer machine module through inventor the study found that under the premise of guaranteeing that normal outer machine compressor does not damage
Liquid matchmaker's valve is closed to the state of one third.In view of this, in the present embodiment, the first presetting position is will be normally outer
Machine module is closed to the position of one third, i.e., the current amount for flowing out the refrigerant in normal outer machine module flows out normal before being only
The one third of the amount of refrigerant in outer machine module.
It is also desirable to which explanation automatically controls the aperture of liquid matchmaker valve using server 10 in the present embodiment
Mode realizes control, but in some other embodiments, can also be by the way that manually-operated gate is arranged, by staff's manual modulation valve
The mode of door is controlled, and the present embodiment does not do any restriction to this.
The aperture of liquid matchmaker's valve of machine module outside the failure is down to the second presetting position by step S106.
It is similar with step S105, since machine module can be controlled as heating mode and work 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 by liquid matchmaker's valve, by the outflow of gas matchmaker's valve.In order to
Realize that, by machine module outside refrigerant discharge failure as fast as possible, liquid matchmaker's valve reduction of the outer machine module of the present embodiment control failure is opened
Degree, so that refrigerant is remained unchanged 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 that the refrigerant outside failure in machine module is gradually 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
It closes to the position of one third.
It is also desirable to explanation, in the present embodiment, step S102- step S104, step S105 and step
S106 has no sequencing.
Step S107 controls the four-way valve that the outer machine module of each failure includes and is 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 for the refrigerant outside failure in machine module to be transferred in normal outer machine module, the outer machine module of failure need to be controlled
In heating state, while controlling normal outer machine module and being in refrigerating state.In the present embodiment, by controlling outer machine module
Four-way valve is in different states, so that the outer machine module of control is in different working conditions.10 meeting of server 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 operational process, and normal outer machine module meeting
Refrigerant is slowly recycled, to realize the transfer of refrigerant.
It should be noted that since the component 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, the work frequency of the outer machine module of failure should be reduced in practical work process
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 also be 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 that machine module outside the failure is controlled after the presetting time completely close.
When being in heating state by machine module outside failure, normal outer machine mode is in refrigerating state after a period of work,
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 need to make the outer machine module of failure in order to which refrigerant outside failure in machine module is discharged all
In liquid matchmaker's valve completely close, guarantee that refrigerant can not be discharged into the outer machine module of failure, the used time is since air-conditioning is also in work
State, so the refrigerant in the outer machine module of failure can be also discharged by gas matchmaker's valve.
It should be noted that the refrigerant in the outer machine module of failure is substantially drained due to after a period of operation, so
It, in a very short period of time can be by the refrigerant outside failure in machine module after completely closing liquid matchmaker's valve of machine module outside failure
It is completely exhausted out, so externally machine module will not cause further to damage.It is tested through inventor, it is in the present embodiment, presetting
Time be 3min of course in other embodiments, actual conditions can also be had more, different preheating setting times is set.
It, can also be by way of the pressure value outside measurement failure in machine module as the another way that the present embodiment is realized
Liquid matchmaker's valve of the outer machine module of control failure completely closes.For example, indicating the outer machine of failure when pressure value is less than or equal to 1Kg
Refrigerant in module is completely expelled, i.e., when pressure value is equal to 1.1Kg, indicates that refrigerant is soon discharged completely, at this time control event
The liquid matchmaker's valve for hindering outer machine module completely closes.
Step S109 acquires 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 so, thening follow the steps S111, if fruit is no, returns to 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.Since 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, i.e. expression 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 closes 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, indicates event
The refrigerant hindered in outer machine module is all discharged, and the outer machine module of failure will be controlled at this time by needing stops with the normal outer machine module
Work, so that the outer machine of staff's degree failure be made to repair.
