Importance.
Below in conjunction with attached drawing description according to blower control method, system and the air-conditioning of the air-conditioning of the embodiment of the present application.
Fig. 1 is the flow chart according to the blower control method of the air-conditioning of the embodiment of the present application.As shown in Figure 1, according to this Shen
Please one embodiment air-conditioning blower control method, include the following steps:
S101: the refrigerant concentration of predetermined sampled point under detection current time.
Wherein, refrigerant concentration is the refrigerant of leakage at leak position or near leak position in a smaller area
Refrigerant concentration.In specific example, refrigerant concentration (that is: refrigerant concentration) can be examined by corresponding refrigerant sensor
It surveys.
Predetermined sampled point refers to some several position outside the medium circulation pipeline of refrigerant, such as: by sensor arrangement
The line connection of refrigerant leakage is comparatively easy to happen in the medium circulation pipeline of refrigerant, to send out in refrigerant
When raw leakage, the refrigerant concentration of leakage can be effectively detected.
S102: the coolant leakage total amount by the end of current time is determined according to refrigerant concentration.
In specific example, fan operation parameter and operation of air conditioner spatial parameter can be obtained first, and according to refrigerant
Concentration, fan operation parameter and operation of air conditioner spatial parameter obtain coolant leakage total amount.
Wherein, fan operation parameter includes the air quantity and indoor fan operation that the indoor fan operation at current time generates
Initial time, operation of air conditioner spatial parameter includes the refrigerant density in operation of air conditioner space and the volume in operation of air conditioner space.
To simplify the description, indoor fan is alternatively referred to as blower.
Such as: current time t, then the refrigerant concentration detected according to current time t can be evaluated whether to obtain and open from blower
Coolant leakage total amount in (i.e. the initial time of fan operation) to this period at current time t at the time of beginning to run, wherein refrigerant
Leakage total amount is Mt。
In a particular application, coolant leakage total amount can be, but not limited to obtain by following formula, the formula are as follows:
Wherein, MtFor by the end of the coolant leakage total amount of current time t, QtThe wind generated for the fan operation of current time t
Amount,For the refrigerant concentration of current time t air-conditioner air outlet,For the refrigerant concentration of current time t air-conditioning air inlet, ρ is sky
Recall the refrigerant density in air port.In addition, the initial time of fan operation is denoted as 0 moment, in this example, MtUnit be g, Qt
Unit be m3/ h,WithUnit be ppm, the unit of ρ is kg/m3, the unit of t is the second.
It can be seen that coolant leakage total amount MtCalculating need by air-conditioning air inlet and air outlet refrigerant concentration and
Density p, and the refrigerant concentration and density p of air-conditioning air inlet and air outlet, can obtain in the following manner:
ρ takes density of the refrigerant at operation of air conditioner space (room as where air-conditioning) temperature and atmospheric pressure;Take detection
The refrigerant concentration of the predetermined sampled point arrived needs the time since refrigerant is spread in operation of air conditioner space, air-conditioning air inlet
Refrigerant concentration then has no more than the mean concentration of refrigerant in operation of air conditioner space:
Wherein, v indicates the space size in operation of air conditioner space (room as where air-conditioning), it may be assumed that volume, unit take m3,
Therefore, available when current time t, coolant leakage total amount MtMeet following relationship:
Wherein, MtIt is just coolant leakage total amount M when being minimizedt。
In the above description, operation of air conditioner space is, for example, the room where air-conditioning.
S103: according to the operating status of coolant leakage overall control blower.
Such as: can be determined according to coolant leakage total amount in air-conditioning remaining refrigerant total amount number, when remaining refrigerant is total
Amount is fewer, illustrates more coolant leakages, and with the continuous operation of blower, the refrigerant of leakage has fully been expanded
It is scattered in air, at this time, it is not easy to there is the phenomenon that local refrigerant excessive concentration, therefore, it is out of service to control blower,
Although, since refrigerant remaining in air-conditioning is more, also being leaked constantly conversely, blower is also being run, it is known that, with not
It leaks disconnectedly, the refrigerant of leakage is not sufficiently diffused in air very much, therefore, it is necessary to continue to control fan operation, to add
The diffusion of quickly cooling matchmaker avoids local refrigerant excessive concentration bring from endangering, such as: when refrigerant is combustible refrigerant, if office
The refrigerant excessive concentration in portion, may cause on fire.
Certainly, when controlling fan operation, the revolving speed of blower can also be adjusted according to refrigerant concentration, such as: if blower
After running a period of time, refrigerant concentration is still very high, then the revolving speed of blower can be promoted, conversely, blower can be reduced suitably
Revolving speed, thus the waste of the energy consumption during avoiding fan operation, and effectively refrigerant can be diffused into air.
In specific example, according to the operating status of coolant leakage overall control blower, comprising: according to coolant leakage total amount
Determine the remaining refrigerant total amount in air-conditioning, and when remaining refrigerant total amount is less than preset value, control blower shutdown, otherwise, control
Blower continues to run.
Such as: coolant injection amount is learnt in advance, so as to determine sky according to coolant leakage total amount and coolant injection amount
Remaining refrigerant total amount in tune, and when remaining refrigerant total amount is greater than preset value, illustrate the remaining refrigerant total amount also phase in air-conditioning
It to more, is also leaked constantly, at this point, control blower continuous service, is diffused into air for the refrigerant constantly leaked
In, it avoids local refrigerant excessive concentration and causes to endanger, it is such as on fire.When remaining refrigerant total amount is less than preset value, illustrate air-conditioning
In remaining refrigerant total amount it is less, leaked substantially, at this point, due to the operation of blower before, by the refrigerant of leakage
It is sufficiently diffused into air, therefore, can control fan parking, local refrigerant excessive concentration will not occur.
In the examples described above, preset value can previously according to experiment determine or it is empirically determined.Usual preset value is set
That sets is relatively small, such as: when total charging amount is 10, preset value can be set as 3 or less.In addition, blower is often referred to indoor wind
Machine, it may be assumed that the operation of indoor fan can accelerate the circulation of the refrigerant of leakage, reduce the concentration of the part of the refrigerant of leakage.
Pass through blower when the refrigerant of air-conditioning leaks according to the blower control method of the air-conditioning of the embodiment of the present application
Operation so that the refrigerant of leakage is sufficiently spread in air, avoid harm caused by local refrigerant excessive concentration,
In addition, can learn whether substantially the refrigerant in air-conditioning complete by leakage according to coolant leakage total amount, and determining that leakage is more abundant
Afterwards, control blower shutdown, the repeatedly starting and stopping of blower when avoiding coolant leakage while promoting air-conditioning service life, reduce leakage
Refrigerant bring security risk.
In one embodiment of the application, the blower control method of air-conditioning, further includes: if making a reservation for adopt under current time
When the refrigerant concentration of sampling point reaches the first predetermined concentration, judges that refrigerant leaks, alarm;When refrigerant concentration reaches second
When predetermined concentration, control blower brings into operation, wherein the second predetermined concentration is greater than or equal to the first predetermined concentration.That is,
When leakage takes place in refrigerant, the concentration in part of the refrigerant of leakage will be promoted constantly, at this point, when the concentration detected reaches
When to a certain amount (that is: the first predetermined concentration), leakage alarm is carried out, thus find that user in time, after further leakage,
Concentration constantly rises, and excessive concentration (as being higher than the second predetermined concentration) will will cause security risk, and therefore, control blower starts to transport
Row, refrigerant is diffused into air, local excessive concentration is avoided to bring security risk.
It is understood that the first predetermined concentration and the second predetermined concentration can be empirically determined, or pass through experiment
It obtains.
