Operating condition in one of them when, control assembly can be directly transferred to meeting the tendency of according to the current operating condition of air conditioner 1000
The optimal value of refrigerant circulation under row operating mode, then, control assembly control to adjust component 200 and adjust current refrigerant circulation
The optimal value of section extremely refrigerant circulation corresponding with current operating condition.For example, being pre-stored with the low wind mould of refrigeration in control assembly
Formula, Refrigeration pattern, the high wind pattern of freezing, low wind pattern is heated, apoplexy pattern is heated, heats several operations such as high wind pattern
Operating mode, at the same be pre-stored with control assembly with the low wind pattern of freezing, Refrigeration pattern, high wind pattern of freezing, heat low wind
Pattern, optimal value A1, A2, A3, A4, A5, the A6 for heating apoplexy pattern, heating the high one-to-one refrigerant circulation of wind pattern,
When current operating condition for freeze low wind when, control assembly control to adjust component 200 by current refrigerant circulation adjust to
A1, after the adjustment, if operating condition is adjusted to the high wind that freezes by user, control assembly controls to adjust component 200 will be current
Refrigerant circulation A1 adjust to A3.
Or, the different operating conditions and different refrigerant circulations of air conditioner 1000 are pre-stored with control assembly
Functional relation between optimal value, control assembly can calculate refrigerant corresponding with the operating condition according to current operating condition and follow
The optimal value of circular rector, then, control assembly control to adjust component 200 act with by current refrigerant circulation adjust to it is current
The optimal value of the corresponding refrigerant circulation of operating condition.
Here, it is necessary to which explanation, the optimal value of refrigerant circulation refers to enable to sky under different operating conditions
Ability efficiency of the device 1000 under the operating condition is adjusted to be in optimum state and the coolant quantity circulated in refrigerant circulation stream.
Thus, air conditioner 1000 according to embodiments of the present invention, by setting adjusting part 200 and control assembly, is utilized
Control assembly is controlled to adjust in the regulation refrigerant circulation of component 200 stream 100 according to the different operating conditions of air conditioner 1000
Refrigerant circulation, so as to advantageously ensure which kind of running status no matter air conditioner 1000 be in, can ensure that refrigerant circulation is
Optimal value under correspondence operating mode, can so effectively improve the ability efficiency of air conditioner 1000, it is to avoid in correlation technique because
The problem of ability efficiency of air conditioner 1000 is low caused by the internal circulating load all same of refrigerant under different operating modes.
In some embodiments of the invention, as shown in fig. 4-5, adjusting part 200 includes fluid reservoir 201, adjustable plate
202 and driving part 203.Specifically, there is in fluid reservoir 201 storage area 2011, adjustable plate 202 it is removable (for example can on
Lower movement) be located in storage area 2011 and accommodated so that storage area 2011 is separated into first receiving space 2011a and second
Space 2011b, such as stepper motor of driving part 203 is connected to drive regulation under the control of control assembly with adjustable plate 202
The movement in storage area 2011 of plate 202 is big to adjust first receiving space 2011a and the second receiving space 2011b volume
It is small.
As shown in Fig. 1-Fig. 3 and Fig. 6, first receiving space 2011a is connected with refrigerant circulation stream 100.Thus, driving is worked as
It is adjustable from first receiving space by the size for adjusting first receiving space 2011a when part 203 drives adjustable plate 202
2011a flows to the number of the coolant quantity in refrigerant circulation stream 100 or adjustment flows to the first appearance from refrigerant circulation stream 100
Receive space 2011a coolant quantity number.
Specifically, as shown in figure 3, adjusting part 200 is multiple, multiple adjusting parts 200 can be connected to refrigerant and follow
In circulation road 100.Thus, it is simple and reliable for structure.
Further, as shown in Fig. 1-Fig. 3 and Fig. 6, first receiving space 2011a is connected to the second of outdoor heat exchanger 2
On refrigerant circulation stream 100 between end and the second end of indoor heat exchanger 3.For example, first receiving space 2011a is connected to room
On refrigerant circulation stream 100 between second end of external heat exchanger 2 and restricting element 4 or first receiving space 2011a connections
To the refrigerant circulation stream 100 between the second end of indoor heat exchanger 3 and restricting element 4.
Specifically, it is connected to the second of outdoor heat exchanger 2 in first receiving space 2011a with shown in Fig. 6 as shown in Figure 1, Figure 2
Hold the second end of indoor heat exchanger 3 between refrigerant circulation stream 100 on the basis of, the second receiving space 2011b also with
Refrigerant circulation stream 100 is connected, and the second receiving space 2011b is connected between the first end of compressor 1 and indoor heat exchanger 3
Or on the refrigerant circulation stream 100 between the first end of compressor 1 and outdoor heat exchanger 2.For example, as shown in fig. 6, working as air conditioner
1000 when being single cold type air conditioner, the second receiving space 2011b may be connected to exhaust outlet 11 and outdoor heat exchanger 2 first end it
Between or the first end of gas returning port 12 and indoor heat exchanger 3 between；As Figure 1-Figure 2, when air conditioner 1000 is cold-warm type air-conditioning
During device, the second receiving space 2011b may be connected between the first end and above-mentioned the second valve port B of outdoor heat exchanger 2, exhaust outlet
11 and first between valve port A, between the valve port D of gas returning port 12 and the 4th or the 3rd valve port C and indoor heat exchanger 3 first end it
Between.
Thus, no matter air conditioner 1000 is in refrigeration mode or heating mode, due to compressor 1 and indoor heat exchanger 3
First end between and the first end of compressor 1 and outdoor heat exchanger 2 between the refrigerant that circulates be gaseous coolant, outdoor is changed
The refrigerant circulated between second end of hot device 2 and the second end of indoor heat exchanger 3 is liquid refrigerants, so when air conditioner 1000
When refrigerant circulation under current operating condition is more than the optimal value of the refrigerant circulation under the operating condition, then control assembly can
Control driving part 203 drives adjustable plate 202 to move to increase first receiving space 2011a volume in storage area 2011
And reduce the second receiving space 2011b volume, consequently facilitating the liquid refrigerants in refrigerant circulation stream 100 enters the first appearance
Receive space 2011a, although the gaseous coolant in the second receiving space 2011b also can be because of the reduction of the volume of the second receiving space 2011
Refrigerant circulation stream 100 is back to, but is due to matter of the liquid refrigerants than the gaseous coolant in unit volume in unit volume
Amount is much larger, and therefore, control assembly still controllable adjustable component 200 subtracts the refrigerant circulation amount in refrigerant circulation stream 100
Optimal value as low as corresponding with current operating condition；When the refrigerant circulation under the current operating condition of air conditioner 1000 is less than
During the optimal value of the refrigerant circulation under the operating condition, then control assembly can control the driving adjustable plate 202 of driving part 203 and exist
The volume to reduce first receiving space 2011a is moved in storage area 2011 and increases the second receiving space 2011b volume,
Consequently facilitating the liquid refrigerants in first receiving space 2011a is entered in refrigerant circulation stream 100, although refrigerant circulation stream
Gaseous coolant in 100 can also flow to the second receiving space 2011b because of the increase of the second receiving space 2011b volumes, but by
More much larger than the quality of the gaseous coolant in unit volume in the liquid refrigerants in unit volume, therefore, control assembly is still controllable
Adjusting part 200 processed by the refrigerant circulation amount in refrigerant circulation stream 100 increase to it is corresponding with current operating condition most
The figure of merit.
And for example, as shown in figure 3, adjusting part 200 is only connected to refrigerant circulation stream by first receiving space 2011a
100 and first receiving space 2011a is connected between the second end of outdoor heat exchanger 2 and restricting element 4 or adjusting part 200
Refrigerant circulation stream 100 is only connected to by first receiving space 2011a and first receiving space 2011a is connected to indoor heat exchange
Between second end of device 3 and restricting element 4, thus, when the refrigerant circulation under the operating condition of air conditioner 1000 is more than the fortune
During the optimal value of the refrigerant circulation under row operating mode, then control assembly can control the driving adjustable plate 202 of driving part 203 in storage
Moved in space 2011 to increase first receiving space 2011a volume, consequently facilitating the liquid in refrigerant circulation stream 100 is cold
Matchmaker enter in first receiving space 2011a with by the refrigerant circulation amount in refrigerant circulation stream 100 be decreased to it is current
The corresponding optimal value of operating condition；When the refrigerant circulation under the operating condition of air conditioner 1000 is less than cold under the operating condition
During the optimal value of matchmaker's internal circulating load, then control assembly can control the driving adjustable plate 202 of driving part 203 and be moved in storage area 2011
The dynamic volume to reduce first receiving space 2011a, consequently facilitating the liquid refrigerants in first receiving space 2011a enter it is cold
It is corresponding with current operating condition so that the refrigerant circulation amount in refrigerant circulation stream 100 to be increased in matchmaker's circulation stream 100
Optimal value due to the refrigerant circulated between the second end of outdoor heat exchanger 2 and the second end of indoor heat exchanger 3 be liquid, this
Sample set can ensure that first receiving space 2011a can store more refrigerant, it is to avoid because first receiving space 2011a directly with
Gaseous coolant circulation section in refrigerant circulation stream 100 is connected and causes first receiving space 2011a can not store more gas
The problem of regulating effect of adjusting part 200 is not good caused by state refrigerant.
Below with reference to Fig. 1-Fig. 6 being described in detail to the structure of the air conditioner 1000 of several embodiments of the invention.
