State controls opening or closing for the first valve 130.Second electronic valve can be electric expansion valve, and indoor unit control panel is used for root
Opening or closing for the second electronic valve is controlled according to the on-off state of indoor unit.
Specifically, under the heating mode of multi-line system, when indoor unit is in off-mode, branching box control panel
The first valve 130 on 140 the first output controlling branchers being connect with indoor unit according to the control of the off signal of indoor unit is closed,
To avoid thermal loss.Indoor unit control panel controls the second electronic valve and closes simultaneously, to avoid refrigerant from flowing through the second electricity
Liquid stream sound is generated when sub- valve, reduces the noise of system.When indoor unit is in open state, 140 basis of branching box control panel
The first valve 130 on starting-up signal control the first output controlling brancher of indoor unit is in the open state, while indoor unit control
It is in the open state that making sheet controls the second electronic valve.
Below in conjunction with the accompanying drawings 4 illustrate this implementation multi-line system operation principle：
In multi-line system heating operation, when each indoor unit is in open state, point of each branching box 100
Discrimination box control panel 140 controls the first valve on the first output controlling brancher thereon according to the starting-up signal of corresponding indoor unit
The first valve 130b on the output controlling branchers of door 130a and second is in opening state.
Wherein, the refrigerant flowed out from the first end of outdoor unit 200 is divided into two-way, the first via after first branching box 100a
Refrigerant is got in through the first output controlling brancher in machine 300a, through the second electronic valve 310a throttlings in indoor unit 300a
Afterwards, the second end of outdoor unit 200 is back to from first liquid side branch pipe 400a being connect with second circulation pipe 520.Second tunnel
Refrigerant enters the N-1 branching box 100b after the second output controlling brancher of first branching box 100a, and the second road refrigerant is again
It is divided into two-way, i.e. third road refrigerant and the 4th road refrigerant.Wherein, first output of the third road refrigerant through the N-1 branching box is controlled
Branch processed enters the N-1 indoor unit 300b, after the throttling of the second electronic valve 310b in the N-1 indoor unit 300b,
The second end of outdoor unit 200 is back to from the N-1 liquid side branch pipe 400b being connect with second circulation pipe 520.4th road is cold
Second output controlling brancher of the matchmaker through the N-1 branching box 100b enters N indoor unit 300c, and later, the 4th road refrigerant is through the
Two circulation pipes 520 are back to the second end of outdoor unit 200.
In multi-line system heating operation, when X (value range of X can be 1~N-1) a indoor unit is in shutdown
When state, then the first valve 130 before control on the second output controlling brancher of X-1 branching box 100 is in opening state,
So that the refrigerant flowed out from the first end of outdoor unit 200 can pass through first circulation pipe 510 and X-1 branching box 100
Second output controlling brancher enters in X branching box 100.The branching box of the corresponding X branching box of X indoor unit 100
The first valve 130 that control panel 140 controls on its first output controlling brancher is closed, meanwhile, the indoor unit control of X indoor unit
Making sheet controls the second electronic valve therein and closes, in this way, the refrigerant flowed out from the first end of outdoor unit 200 cannot pass through X
A indoor unit to reduce thermal loss, while avoiding refrigerant and forming liquid stream sound in X indoor unit, reduces and is
The noise of system.Only when+1 indoor unit of X to n-th indoor unit is in off-mode, then X branching box is controlled
The first valve 130 on 100 the second output controlling brancher is closed.
In another embodiment, as shown in figure 5, the quantity of branching box 100 is one, branching box 100 includes input pipe
Road 110 and N number of output pipe 120, connect first valve 130 of each output pipe 120 form output controlling brancher, i.e., this
Branching box 100 in embodiment is identical as the structure of branching box 100 shown in Fig. 2.N number of output controlling brancher and N number of indoor unit
It is arranged in a one-to-one correspondence, i.e., is arranged in parallel between N number of indoor unit.
Outdoor unit 200, first circulation pipe 510, intake line 110, n-th output controlling brancher, n-th indoor unit and the
Two circulation pipes 520 are connected by circulation successively.The refrigerant exported from the first end of outdoor unit 200 is through first circulation pipe 510 and input
It is divided into the roads N after pipeline 110, the roads N refrigerant enters the after n-th exports controlling brancher and its corresponding n-th indoor unit respectively
Two circulation pipes 520, in second circulation pipe 520 mixed refrigerant return to outdoor unit 200 second end.In the present embodiment,
It is arranged in parallel between each indoor unit, independent control is more convenient to use.
Further, each indoor unit includes indoor unit control panel and the second electronic valve, and each branching box 100 includes
Branching box control panel 140；Branching box control panel 140 is connected with the communication of indoor unit control panel, in the present embodiment, indoor unit control panel
Can be connected by way of the wireless communications such as purple peak, bluetooth or Wifi with branching box control panel 140, realize branching box 100 with
Information exchange between indoor unit.The switching on and shutting down for the indoor unit that branching box control panel 140 is used to be transmitted according to indoor unit control panel
State controls opening or closing for the first valve 130.Second electronic valve can be electric expansion valve, and indoor unit control panel is used for
Opening or closing for the second electronic valve is controlled according to the on-off state of indoor unit.
The operation principle of the multi-line system of 4 illustration the present embodiment below in conjunction with the accompanying drawings：
As shown in figure 4, the quantity of the output pipe of branching box is 5, be arranged in series on each output pipe there are one
First the first valve of 130,5, valve is respectively labeled as 130a~130e；The quantity of indoor unit is also 5, is respectively labeled as
300a~300e.
