Detailed description of the invention
In the following detailed description, a large amount of specific detail is proposed, in order to provide of the present utility model
Thorough understanding.However it will be understood by those of ordinary skill in the art that, even if not having these specific detail can implement yet
This utility model.In other cases, be not described in well-known method, process, assembly and
Circuit, in order to avoid impact is to understanding of the present utility model.
In conjunction with shown in Figure 1, according to embodiment of the present utility model, outdoor heat exchanger includes that parallel connection sets
The multiple heat exchange branches 1 put, at least one heat exchange branch 1 are provided with and control heat exchange branch 1 break-make
Control valve 2.
When air-conditioner is in refrigerating state, the heat exchange branch 1 of outdoor heat exchanger all connects so that room
The condensation area of external heat exchanger is more than the disengagement area of indoor heat exchanger, so that outdoor heat exchanger is with indoor
Heat exchanger has identical heat exchange efficiency；When air-conditioner is in and heats state, now outdoor heat exchanger is made
Using for vaporizer, indoor heat exchanger uses as condenser, can pass through control valve 2 cutoff room
The heat exchange branch 1 of external heat exchanger, reduces the disengagement area of outdoor heat exchanger so that indoor heat exchanger cold
Solidifying area is more than the disengagement area of outdoor heat exchanger, so that outdoor heat exchanger has phase with indoor heat exchanger
Same heat exchange efficiency, and then make indoor set match with the heat exchange efficiency of off-premises station, improve the work of air-conditioner
Make efficiency.By the state of control valve 2 is adjusted, can heat exchange to outdoor heat exchanger easily
Area is adjusted so that it is match with the heat exchange area of indoor heat exchanger so that the condensation of air-conditioner is born
Lotus can match with evaporation load all the time, reduces the operation power of air-conditioner, improves the Energy Efficiency Ratio of complete machine.
Preferably, control valve 2 is check valve, and check valve turns on when outdoor heat exchanger is in refrigerating state,
It is in when heating state and ends.When air-conditioner is in refrigerating state, owing to now check valve turns on, because of
This heat exchange branch 1 is all in connected state, and the condensation area of outdoor heat exchanger is more than the steaming of indoor heat exchanger
Fermentation is long-pending, and the condensation load of air-conditioner can be made to match with evaporation load, and the work reducing air-conditioner is damaged
Consumption, improves the service behaviour of air-conditioner.
This control valve 2 can also be hydraulic valve, flow control valve or electromagnetic valve etc..
Outdoor heat exchanger also includes super cooled sect 3, connects with super cooled sect 3 after the parallel connection of multiple heat exchange branch 1.
Super cooled sect 3 can carry out cold treatment to outdoor heat exchanger 3 so that when air-conditioner is in cooling condition,
Indoor set can be entered into after super cooled sect 3 is supercool from the cold-producing medium of heat exchange branch 1 outflow to steam
Send out heat exchange, it is possible to be effectively improved the refrigerating capacity of air-conditioner, reduce the energy consumption of air-conditioner.
Preferably, each heat exchange branch 1 includes two heat exchanging pipes being arranged in parallel 4, two heat exchanging pipes
4 are positioned at same rectangular area.Two heat exchanging pipes 4 of same heat exchange branch 1 are arranged on unified act
In row region, it is simple to heat exchanging pipeline is arranged, and it is more uniform to enable to heat exchanging pipe distribution
Rationally, the heat exchange efficiency of heat exchange branch 1 entirety is improved.
Preferably, two heat exchanging pipes 4 of same heat exchange branch 1 are arranged in a crossed manner, can make two heat exchange
The heat distribution of pipeline 4 is more uniform, and heat exchange is more uniform, improves the heat exchange of outdoor heat exchanger further
Efficiency.
When heat exchanging pipe 4 is in refrigerating state, a heat exchanging pipe 4 of at least one heat exchange branch 1
Outlet is provided with the control valve 2 controlling this heat exchanging pipe 4 break-make.Owing to heat exchange branch 1 only one of which is changed
The outlet of pipe line 4 is provided with control valve 2, when operating control valve 2, can only disconnect one every time
Individual heat exchanging pipe 4, can improve the heat exchange area degree of regulation of heat exchanging pipeline 4 so that outdoor heat exchange
The heat exchange area of device can more accurately heat exchange area with indoor heat exchanger match.For heat-transfer surface
The outdoor heat exchanger that long-pending adjustment is bigger, can operate the control on the heat exchanging pipe 4 of multiple heat exchange branch 1
Valve 2 is adjusted.
At the exit position of arbitrary heat exchanging pipe 4 that control valve 2 can be arranged on same heat exchange branch 1,
At one of them heat exchanging pipe 4 of all of heat exchange branch 1, control valve 2 all can be set, it is also possible to only
Control valve 2 is set at one of them heat exchanging pipe 4 of part heat exchange branch 1, specifically can be according to sky
The disengagement area of outdoor heat exchanger under device heating condition is adjusted to determine with the condensation area of indoor heat exchanger.
It is provided with control valve 2 on pipeline between at least one heat exchange branch 1 and super cooled sect 3.This kind of feelings
Under condition, when operating control valve 2, control is the break-make of whole heat exchange branch 1, therefore changes outdoor
The adjustment amplitude of the heat exchange area of hot device is relatively big, regulates convenient.
When outdoor heat exchanger is in refrigerating state, the exit of heat exchange branch 1 is provided with hair fastener pipe 5, control
Valve 2 processed is arranged on the pipeline between hair fastener pipe 5 and super cooled sect 3.
According to embodiment of the present utility model, air-conditioner includes outdoor heat exchanger, and this outdoor heat exchanger is upper
