Switch between state, to switch between refrigeration, heating mode in air-conditioning system.
Air-conditioning system of the invention is specifically introduced respectively below by way of attached drawing 4 to 9 to be under refrigeration or two under heat pattern
Kind working condition and its working principle.(drawing in this case mainly indicates connection relationship and refrigerating fluid flow direction between component, and
The installation site of component is not limited.Solid arrow indicates the refrigerating fluid flow direction under refrigeration mode, and dotted arrow indicates heating mode
Under refrigerating fluid flow direction.)
As shown in Figs. 4-6, when air-conditioning system of the invention is in refrigeration mode, wherein the first indoor heat exchanger 7 and second
The air duct of indoor heat exchanger 9 be it is parallel, be each provided with first indoor fan 13 of a separately adjustable air quantity, wind in second Room
Machine 14, forms two air ducts side by side, two indoor heat exchangers can separately adjustable corresponding blower air quantity.
At this point, the first four-way reversing valve 5 and the second four-way reversing valve 6 of air-conditioning system of the invention are in the first conducting
State.The 51 connection third interface 53 of first interface of first four-way reversing valve 5, second interface 52 are connected to the 4th interface 54.Second
The 61 connection third interface 63 of first interface of four-way reversing valve 6, second interface 62 are connected to the 4th interface 64.
Refrigerating fluid divides two-way through the first four-way reversing valve 5 and the second four-way reversing valve 6, to converge respectively after the discharge of compressor 1
It is divided into two-way after always carrying out hot-cast socket to outdoor heat exchanger 4.Cryogenic refrigeration liquid is passed through into first throttling device 8 all the way, flows into the
Then high-temperature refrigeration liquid is flowed back into the first liquid storage of compressor 1 by one indoor heat exchanger 7 again by the first four-way reversing valve 5
Device 2.Cryogenic refrigeration liquid is passed through second throttling device 10 by another way, the second indoor heat exchanger 9 is flowed into, then by high-temperature refrigeration liquid
The second liquid storage device 3 of compressor 1 is flowed back into again by the second four-way reversing valve 6.
Also, the air duct of the first indoor heat exchanger 7 and the second indoor heat exchanger 9 is parallel.First indoor heat exchanger, 7 He
Second indoor heat exchanger 9 can work in different evaporating temperatures, such as: the evaporating temperature of the first indoor heat exchanger 7 is 18 °,
Meet sensible heat, realizes refrigeration effect.And the evaporating temperature of the second indoor heat exchanger 9 is 8 °, meets latent heat, it is real by condensation form
Existing effect on moisture extraction.
As shown in Figs. 7-9, when air-conditioning system of the invention is in heating mode, wherein the first indoor heat exchanger 7 and second
The air duct of indoor heat exchanger 9 be it is parallel, be each provided with first indoor fan 13 of a separately adjustable air quantity, wind in second Room
Machine 14, forms two air ducts side by side, two indoor heat exchangers can separately adjustable corresponding blower air quantity.At this point, sky of the invention
The first four-way reversing valve 5 and the second four-way reversing valve 6 of adjusting system are in the second on state, 51 connection the 4th of first interface
Interface 54, second interface 52 are connected to third interface 53.
At this point, the first four-way reversing valve 5 and the second four-way reversing valve 6 of air-conditioning system of the invention are in the second conducting
State.The 4th interface 54 of 51 connection of first interface of first four-way reversing valve 5, second interface 52 are connected to third interface 53.Second
The 4th interface 64 of 61 connection of first interface of four-way reversing valve 6, second interface 62 are connected to third interface 63.
Refrigerating fluid divides two-way after the discharge of compressor 1, flows into the first indoor heat exchanger 7 through the first four-way reversing valve 5 all the way,
Carry out heat exchange；Another way flows into the second indoor heat exchanger 9 through the second four-way reversing valve 6, carries out heat exchange.
First indoor heat exchanger 7 and the refrigerating fluid of the second indoor heat exchanger 9 outflow respectively pass through first throttling device 8 and the
Two throttling sets 10 summarize after carrying out hot-cast socket to outdoor heat exchanger 4 and are divided into two-way.It is returned all the way through the first four-way reversing valve 5
Flow to the first liquid storage device 2 of compressor 1.Another way flows back into the second liquid storage device 3 of compressor 1 through the second four-way reversing valve 6.And
And first indoor heat exchanger 7 and the second indoor heat exchanger 9 air duct be it is parallel, it is common to heat.
Since dining area D (referring to attached drawing 2), humidity is relatively large, during human body is had a meal, needs lower adjusting
Temperature may be configured as the lower latent heat region of evaporating temperature；It is higher that parlor region C (referring to attached drawing 2) may be configured as evaporating temperature
Sensible heat region.Time other than having a meal, based on the C of parlor region, evaporating temperature is relatively high, slightly larger air quantity, improves people
Body comfort；And at this time dining area D can low speed wind model operation, indoor humidity load is born, while because gentle breeze operates, to human body
Substantially uncomfortable feeling is not will cause.Air-conditioning system through the invention can control two evaporations in two regions simultaneously
Temperature realizes dining room, parlor region in different moments, and different evaporating temperatures improves the efficiency of system overall operation.
Compressor in the present invention is twin-tub, double suction gas, double liquid storage device compressors, and compressor is according to different load, two
Different volumetric ratios is arranged in cylinder, realizes the control of different evaporating temperatures.Double evaporating temperature compressor applications are in " warm and humid sub-control "
One drag two air-conditioning system when, dining room, parlor indoor unit undertake the load of latent heat, sensible heat respectively.The present invention is applied to " double steamings
When the one drag two air-conditioning system of hair temperature double-control ", two indoor units depending on the application, can be set different evaporating temperatures and be divided
It does not control, provides district grid air-conditioning solution in stateroom (such as: including the parlor region C and dining area D being connected)
Certainly scheme.
In summary, air-conditioning system of the invention can be realized in two regions while control two evaporating temperatures, realize
In different moments, different evaporating temperatures improves the efficiency of system overall operation for dining room, parlor region.
The above is only specific application examples of the invention, are not limited in any way to protection scope of the present invention.Except above-mentioned
Outside embodiment, the present invention can also have other embodiment.All technical solutions formed using equivalent substitution or equivalent transformation,
