Sufficient certain proportion relationship.Such as the 3 circuit quantity of metal tube that first part 1 and second part 2 are arranged can be identical；Second
Points 23 circuit quantity of metal tube may be set to be 2-3 times of 3 circuit quantity of metal tube in first part 1, wherein can fit
When the 3 circuit quantity of metal tube for adjusting the second configuration section.
The specific control mode of the air-conditioning that an embodiment of the present invention is related to need to realize, controller can be adopted using controller
With existing single-chip microcontroller or PLC controller, or directly adopt the master that air-conditioning is commonly integrated with control circuit, power circuit
The integrated circuit board of plate, mainboard namely air-conditioning is also integrated with temperature sensor, basic shut-off valve 22, supplement on integrated circuit board
Shut-off valve 12 and electronic valve are electrically connected with the controller.The temperature information of temperature sensor acquisition is transferred to controller, controller
Temperature information is compared and is controlled according to pre-set programs: basic shut-off valve 22 and supplement shut-off valve 12 it is on and off with
And the opening quantity of supplement shut-off valve 12.
Air-conditioning can be realized according to pre-set programs and be automatically controlled, alternatively, another embodiment of the utility model is also settable outer
Portion's remote controler, external remote are provided with the button being electrically connected with the controller, and button is corresponding to control each shut-off valve, and user is according to reality
The shut-off valve and shut-off valve quantity that border is opened needed for needing to manually adjust.
Another embodiment of the utility model additionally provides a kind of control method of air-conditioning, and the air-conditioning is any of the above-described institute
The air-conditioning stated, control method include the following steps:
After controlling air-conditioning booting, target temperature value T2 is set；
After running preset time, acquisition air-conditioning ambient temperature value T1 in the room；
The ambient temperature value T1 is compared with set temperature value T2, obtains temperature difference △ T, according to the temperature difference △ T
Determination opens or closes the first part 1, the area that the evaporator participates in heat exchange is controlled whereby, to control air-conditioning
Run power.
In specific one embodiment, further comprise the steps of:
Air-conditioning actual operating efficiency value is calculated according to the temperature difference △ T, if the actual operating efficiency value is lower than default
Operational efficiency value then controls and increases the area that the evaporator participates in heat exchange；Alternatively,
Air-conditioning actual operating efficiency value is calculated according to the temperature difference △ T, is preset if the actual operating efficiency value is higher than
Operational efficiency value then controls and reduces the area that the evaporator participates in heat exchange.
The operational efficiency of air-conditioning refers to refrigeration or heating efficiency of the air-conditioning in certain area room.
In specific one embodiment, when usable floor area is bigger than normal (user, which opens all room doors, to cause), refrigeration is opened
Or heating, when refrigeration effect is bad, temperature declines slow；Or temperature rise is slow when heating, causes comfort bad.It is with refrigeration
Example, takes air conditioning control method provided in this embodiment at this time:
Under normal circumstances, supplement shut-off valve 12 belongs to closed state, and basic shut-off valve 22 is also at opening state (i.e. air-conditioning
In configurations operating status)；
After controlling air-conditioning booting, by several seconds after default gear operation 10min, the temperature difference △ T is detected:
When 5 DEG C of △ T >, specifically, the present embodiment at 5 DEG C -8 DEG C, opens the basic supplement of shut-off valve 22, first cut-off
Valve 121 and the second supplement shut-off valve 122, close third and supplement shut-off valve 123；
It when 5 DEG C 2 DEG C of < of < △ T, opens basic shut-off valve 22 and third supplements shut-off valve 123, close the first supplement and cut
Only valve 121 and the second supplement shut-off valve 122；
When 0 DEG C 2 DEG C of < of < △ T, basic shut-off valve 22 is opened, closes supplement shut-off valve 12.
Due to the temperature spot stopping function of air-conditioning, the temperature difference is at 0 DEG C of < without adjusting shut-off valve in the case of freezing.
Specific adjustment mode can be used automatic control or manually control remote controler.
Air-conditioning booting operation 10min, tends towards stability to room temperature control ability, passes through detection ambient temperature value and setting
The difference of temperature value, the shut-off valve opened needed for controlling is to adjust air-conditioning cold flow section size.
In another specific embodiment, when user is less than normal using room area (for example former parlor is transformed, and is increased
Interlayer, when room door is all closed), when opening refrigeration or heating, refrigeration temperature drop is too fast, and user feels too cold or temperature
What is risen is too fast, and user experience is too warm, causes comfort bad.It is configured by adjusting reducing, the room Lai Gaishan comfort.At this time
Take air conditioning control method provided in this embodiment:
And since compressor of air conditioner is to guarantee that compressor reliability has most short 6min runing time requirement, run in this 6min
It detects whether temperature overshot situation occur in time, after control air-conditioning booting, by default gear operation 5min and detects the temperature
Poor △ T,
When 5 DEG C of △ T >, basic shut-off valve 22 and supplement shut-off valve 12 are closed；
When 5 DEG C 2 DEG C of < of < △ T, basic shut-off valve 22 is opened, closes supplement shut-off valve 12；
When 0 DEG C 2 DEG C of < of < △ T, basic shut-off valve 22 and supplement shut-off valve 12 are closed, is handled by temperature spot shutdown.
Specific adjustment mode can be used automatic control or manually control remote controler.
The cooling capacity section of air-conditioning is adjusted, by above-mentioned control method to improve comfort.
