The pressure value of refrigerant in amount air-conditioner refrigerating circuit, and the data is activation that will be measured gives the drive mechanism 107, the driving
The plunger member 102 according to the data-driven for receiving of mechanism 107 is moved.
It should be noted that the inlet 104 and leakage fluid dram 105 of adjustable refrigerant memory 1 are directed to air-conditioner and exist
For situation about being run under refrigeration mode, because refrigerant flows to outdoor heat exchanger 4 from compressor 2 under refrigeration mode, and from
The adjustable refrigerant memory 1 of the flow direction of outdoor heat exchanger 4.And be directed to the air-conditioner under heating mode, due to refrigerant from
Indoor heat exchanger 3 is introduced into after being flowed out in compressor 2, then enters adjustable refrigerant memory 1 by throttling arrangement 6, this
When refrigerant adjustable refrigerant memory 1 is entered into by " leakage fluid dram 105 ", and by " inlet 104 " from adjustable restraining
Cryogen memory 1 is discharged.
It should be noted that operation of the present embodiment one only for air-conditioner in refrigeration mode is illustrated.As for sky
Device is adjusted to be in the situation of heating mode, due to entering into the refrigerant pressure of adjustable refrigerant memory 1 by throttling arrangement 6
Very little, so that adjustable refrigerant memory 1 does not play refrigerant adjustment effect now substantially.Therefore in a heating mode, drive
Mechanism 107 need not control the motion of plunger member 102, only plunger member 102 need to be fixed on into a certain ad-hoc location, so that connecing
The adjustable refrigerant memory 1 for entering is equal to refrigerant line.Thus, the air-conditioner of the present embodiment one, it can also
The machine of refrigeration is used exclusively for, so that it can be not provided with reversing arrangement 5.
Additionally, the pressure value in order to measure refrigerant in air-conditioner refrigerating circuit, the position of pressure sensor can be flexible

When the air-conditioner of the present embodiment is used to freeze, when air conditioner refrigerant high-pressure is too high, drive mechanism control
Plunger member processed 102 is moved, to cause that the volume of fluid reservoir 103 increases, so that the part of refrigerant storage in the pipeline of air-conditioner
In fluid reservoir 103, the pressure reduction of refrigerant, requires, now until refrigerant high pressure pressure value meets in air-conditioner hose
The control of drive mechanism 107 plunger member 102 is still in current location.
Especially when being freezed under air-conditioner is placed on high temperature or hyperthermal environments, from the system out of outdoor heat exchanger 4
Cryogen has pressure very high, and now storing refrigerant by adjustable refrigerant memory 1 discharges pressure, can effectively solve
The problem that user's high temperature cannot freeze.
Wherein, environment temperature is higher, and the refrigerant high pressure pressure value of air-conditioner is bigger, so that the control plug of drive mechanism 107
The stroke of the motion of part 102 is bigger, and fluid reservoir 103 can store more refrigerants, effectively to alleviate air conditioner refrigerant high pressure
The too big problem of pressure value.Assuming that environment temperature is 65 DEG C of limiting temperature, then the now control of drive mechanism 107 plunger member 102
Minimum point is moved to, now the volume of fluid reservoir 103 reaches maximum, so as to store refrigerant to greatest extent, reduce participation and follow
The refrigerant amount of ring, it is ensured that normally freeze under hyperthermal environments in air-conditioner, solves user's high temperature air-conditioner stop jumping without legal system
Cold problem.
Similarly, when the refrigerant pressure of refrigerant in air-conditioner is too low, if stored in adjustable refrigerant memory 1
Have if refrigerant, then by drive mechanism 107 plunger member 102 can be driven to move to cause that the volume of fluid reservoir 103 reduces,
So as to adjustable refrigerant memory 1 is to refrigerant release in the refrigerating circuit of air-conditioner.Until refrigerant high pressure pressure value is full
Foot is required, or refrigerant in fluid reservoir 103 discharges completely, the now control of drive mechanism 107 remains stationary of plunger member 102.

The pressure value of refrigerant in S2, measurement air-conditioner refrigerating circuit, including air conditioner refrigerant high-pressure value PIt is real, and
The data is activation that will be measured is to drive mechanism；
S3, by PIt is realThe maximum refrigerant high pressure pressure value P allowed when freezing with air-conditionerIfContrasted：
If PIt is real≤PIf, then driving mechanisms control plunger member transfixion, so as to keep PIt is realIt is constant；
If PIt is real＞ PIf, then driving mechanisms control plunger member motion is increased with the volume for causing fluid reservoir, so that PIt is real
Value reduces, until PIt is real=PIf；
S4, when be stored with fluid reservoir refrigerant when, if PIt is real≤PIf, then driving mechanisms control plunger member motion with cause
The volume of fluid reservoir reduces, so as to refrigerant release in air-conditioner refrigerating circuit.
In the present embodiment one, refrigerant in air-conditioner refrigerating circuit is mainly judged by refrigerant high pressure pressure value
Whether pressure value meets requirement, can also carry out the judgement of pressure value by other equivalent parameters certainly.
It is further comprising the steps of when the throttling arrangement 6 is electric expansion valve：

Determine suction temperature T0Difference is done, the return-air degree of superheat Δ T=T of compressor 2 is tried to achieves-T0：
If △ T ＜ -1, illustrate that refrigerating system coolant flow is too big, evaporating temperature is relatively low, and electronic expansion valve opening turns one down
Level；
If △ T ＞ 1, illustrate that refrigerating system coolant flow is less than normal, evaporating temperature is higher, and electronic expansion valve opening tunes up one
Level；
If -1≤△ T≤1, current refrigeration system running state is illustrated preferably, keep Current electronic expansion valve opening constant.
Obviously, as the electric expansion valve of throttling arrangement, its aperture regulation with air-conditioner whole service process, its
Although S4, it is not intended that the time is upper and S1-S3 has precedence relationship.And it is possible to an execution cycle t is set,
So as to judge a size of return-air degree of superheat Δ T every time t, and electronic expansion valve opening is adjusted according to each judgement.
