Specific embodiment
To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below
It will be described in further detail in conjunction with technical solution of the attached drawing to the embodiment of the present invention, it is clear that described embodiment is only
It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
As shown in Figure 1, the structural schematic diagram of its indoor unit 10 for the present embodiment comprising heat exchanger.The cabinet of indoor unit 10
Heat exchanger, expansion valve 9, coolant distributor 6 and blower 8 etc. are provided in 7.A side bottom on cabinet 7 far from heat exchanger opens up
There is air intlet (not shown), the top of cabinet 7 offers air outlet slit (not shown).Indoor air is in blower
Enter in cabinet 7 under the action of 8 from the air intlet of bottom, by heat exchanger, temperature in the higher air of temperature and heat exchanger
Heat exchange occurs for lower refrigerant, and finally from the air outlet slit discharge at 7 top of cabinet.
Coolant distributor 6 is connected to expansion valve 9 and heat exchanger, and the refrigerant in expansion valve 9 is through 6 inflow heat exchanger of coolant distributor
In.Heat exchanger includes cooling fin 1, the multiple tracks refrigerant pipeline 2 in cooling fin 1 and the first collection being set to outside cooling fin 1
Pipe 3 and the second collector 4.Several fin (not shown)s are provided in cooling fin 1, to increase overall heat exchange area.Refrigerant pipe
The one end on road 2 is refrigerant inlet, and the other end is refrigerant exit.The refrigerant exit of part refrigerant pipeline 2 is connected to the first collector 3,
The refrigerant exit of remaining refrigerant pipeline 2 is connected to the second collector 4.It is additionally provided with dehumidification valve 5 on first collector 3, passes through dehumidification valve 5
Opening and closing can control circulation and stagnation of the refrigerant in the first collector 3 and the refrigerant pipeline 2 being connected to the first collector 3.The
The one end not connect with refrigerant exit on one collector 3 and the connection of the second collector 4.Refrigerant is flowed in refrigerant pipeline 2 and is finally passed through
First collector 3 and the second collector 4 are only flow in the compressor of outdoor unit through the second collector 4.
When air-conditioning is substantially carried out refrigeration, the dehumidification valve 5 on the first collector 3 is in the open state, low temperature refrigerant pass through with it is swollen
The connected coolant distributor 6 of swollen valve 9 flows into the refrigerant pipeline 2 being located in cooling fin 1, and the temperature of entire heat exchanger is lower.Room
The interior higher air of temperature by blower 8 sucks cabinet 7 and by the cooling fin 1 of heat exchanger, be located in cooling fin 1 and temperature compared with
Heat exchange occurs for the low higher air of refrigerant and temperature, and air is cooled down, and at the same time, the portion of water in air is to the cold
And dew is condensed on the surface of cooling fin 1, effectively freezed and the air after centainly dehumidifying is finally from the air at 7 top of cabinet
Outlet discharge.Meanwhile the refrigerant of liquid absorbs the heat in air and is sublimed into gaseous state, high-temperature gas refrigerant is in refrigerant pipeline 2
Middle flowing, and finally flow in the compressor of outdoor unit through the first collector 3 and the second collector 4.The unlatching of dehumidification valve 5 can make
Refrigerant circulates in all refrigerant pipelines 2 in entire heat exchanger, efficiently use whole heat exchange areas, improve heat exchange
The heat exchange efficiency of device, mainly to realize refrigerating function and carry out a degree of dehumidifying.
When air-conditioning is substantially carried out dehumidifying, the dehumidification valve 5 on the first collector 3 is closed, be now placed in the first collector 3 with
And the refrigerant in the refrigerant pipeline 2 being connected to the first collector 3 will be unable to circulate, the exchange capability of heat very little of this part refrigerant, heat exchange
Effective refrigerant in device is the refrigerant to circulate in the refrigerant pipeline 2 being connected in the second collector 4 and with the second collector 4.Pass through
Dehumidification valve 5 is closed, come the effective heat exchange area of the amount of the refrigerant for the circulation being substantially reduced in heat exchanger and heat exchanger, thus quickly
The overall heat exchange ability of heat exchanger is reduced, refrigerant is changed into gaseous transformation ability by liquid and reduces in heat exchanger, in heat exchanger
Integral pressure reduce, and then reduce heat exchanger in refrigerant evaporating temperature, i.e., quickly reduce whole system temperature, make system
Temperature be rapidly achieved the dew-point temperature of air, condense out more moisture, realize rapid moisture removal.
Further, the quantity for the refrigerant exit that settable first collector 3 is connected is connected cold greater than the second collector 4
The quantity of matchmaker outlet, so that the flow of effectively refrigerant substantially reduces in heat exchanger after the closing of dehumidification valve 5, faster to reduce heat exchanger
Bulk temperature and to drop to the temperature of heat exchanger lower.
In addition, since the flow for flowing through the refrigerant in expansion valve 9 is reduced, so that the energy consumption of expansion valve 9 also accordingly reduces.
Heat exchanger provided in this embodiment quickly reduces the amount of effective refrigerant in system, reduces by closing dehumidification valve 5
The overall heat exchange ability of heat exchanger to quickly reduce the pressure in heat exchanger, and then reduces the evaporating temperature of refrigerant, so that changing
The bulk temperature of hot device can be rapidly achieved the dew-point temperature of air, realize rapid moisture removal.
The present embodiment also provides a kind of air-conditioning, and the indoor unit 10 of the air-conditioning includes above-mentioned heat exchanger, is able to carry out and quickly removes
It is wet, and energy consumption is lower.Drainpipe (not shown) is additionally provided in the air-conditioning, one end of drainpipe is located at the machine of indoor unit 10
In case 7, the liquid water for being condensed in 1 surface of cooling fin can be guided to outdoor.
Note that the above is only a better embodiment of the present invention and the applied technical principle.It will be appreciated by those skilled in the art that
The invention is not limited to the specific embodiments described herein, be able to carry out for a person skilled in the art it is various it is apparent variation,
It readjusts and substitutes without departing from protection scope of the present invention.Therefore, although being carried out by above embodiments to the present invention
