" embodiment ", which represents a particular feature, structure, or characteristic described in conjunction with the embodiments, in the present invention may be embodied in this
In at least one embodiment of application.In the description, the phrase, which occurs, in each position might not each mean identical implementation
Example, nor the independent or alternative embodiment with other embodiments mutual exclusion.It will be understood by those skilled in the art that this paper institute
The embodiment of description can be combined with other embodiments.
Air-conditioner control method according to the present invention is mainly used in heating mode.Air conditioner operates in heating mode
Under, since outdoor environment temperature is lower, outdoor heat exchanger meeting frosting needs to defrost in time, avoids the fortune for influencing air conditioner
Row effect.The mode of defrosting is consistent with the prior art, is commutated using four-way valve, and heating mode is changed to refrigeration mode.Freezing
Under mode, the higher refrigerant of temperature can flow through outdoor heat exchanger, melt the frost layer on outdoor sensor surface.
As shown in Figure 1, in a kind of embodiment air-conditioner control method the following steps are included:
Step S10, judges whether air conditioner current operating conditions meet defrosting condition.
Judgement of the judgement of defrosting condition mainly to defrost opportunity, that is, need to judge outdoor heat exchanger surface, especially
The degree of coil surface frosting determines when to start defrost.Outdoor coil pipe used frosting is affected by many factors, including outdoor empty
The corresponding different refrigerant properties of temperature degree, water capacity, different refrigerant types, coil pipe material etc., these factors can all influence
The speed of frosting, frosting degree；And corresponding different air conditioner type, frosting velocity and frosting degree can influence air-conditioning to some extent
It operates normally.When frosting, due to the increase of outdoor heat exchanger coil surface frost layer, the thermal resistance of outdoor heat exchanger is caused to increase, room
The heat exchange amount of external heat exchanger is gradually reduced.When frost layer increases to certain thickness, heat exchange amount just declines rapidly, corresponds to air-conditioning
The evaporating pressure and evaporating temperature of device will also start to accelerate decline.Decline in outdoor heat exchanger coil pipe pressure and coil temperature same
When, the coil temperature and pressure of indoor coil also decline therewith.Based on the above principles, defrosting condition is set as including time and temperature
Degree or two conditions of time and pressure, for example, being set as outdoor unit continuous operation to setting defrosting time, and outdoor disk simultaneously
Tube temperature degree is less than or equal to the first setting defrosting temperature and is determined as when indoor coil pipe is less than or equal to the second setting defrosting temperature
Meet defrosting condition.Setting defrosting time can be set to outdoor unit continuous operation 35 to 45 minutes, the first setting defrosting temperature
It is -5~-8 degrees Celsius, the second defrosting temperature is 40 to 45 degrees Celsius.Set defrosting time, the first defrosting temperature and the second defrosting
Temperature can be adjusted according to outdoor environment temperature, such as call the proportionality coefficient of storage, be removed to setting defrosting time, first
White temperature and the second defrosting temperature are corrected.
Step S11 executes defrosting process if meeting defrosting condition.
If meeting defrosting condition, start to defrost.A kind of optional defrosting process is that compressor, outdoor fan are simultaneously
It shuts down, the first timer starts timing until first effective time-count cycle, four-way valve power down commutation.Second timer starts timing
Until second effective time-count cycle, compressor is opened, and starts Defrost operation.The first effective time-count cycle that was delayed can make outdoor
Pressure difference between heat exchanger and indoor heat exchanger reduces, so that the operation of compressor is more steady, avoids causing not compressor
Necessary impact.It can be set to 30s first effective time-count cycle, can be set as 2 to 5 seconds for second effective time-count cycle.It removes
White process is also based on the prior art and carries out necessary adjustment, and details are not described herein.
Step S12 samples the supply air temperature of air outlet of indoor set.
During Defrost operation, the supply air temperature of air outlet of indoor set depends on the surface temperature of indoor heat exchanger.Pass through
Supply air temperature can predict influence of the air-supply to air-conditioned room during defrosting.Supply air temperature can be gone out by the way that machine indoors is arranged
The wind pushing temperature sensor in air port measures.
Step S13, compares supply air temperature and set temperature.
Step S14 controls opening electric heater if supply air temperature is less than set temperature.
In frosting, due to the influence of frost layer, the surface temperature of outdoor heat exchanger and indoor heat exchanger can decline, but
It is that, since the heating operation of certain time has been carried out, room temperature is basically stable near set temperature, fluctuation is little,
It is the temperature that a user is comfortable on.And the surface temperature of indoor heat exchanger is still much higher than set temperature, such as second sets
Surely defrosting temperature is typically set in the section of 40 to 45 degree, much higher than air-conditioned room temperature achieved desired by user.
It blows under these conditions, supply air temperature is also higher.The decline that not will lead to indoor air temperature in air conditioned building not only, can also be one
Determine to compensate temperature loss caused by during defrosting in degree.If control electric heater is started to work at this time, send
Air temperature can increase sharply, and compressor may be easy to make with it also in shutdown status, the air-supply blow-through of overheat to user at this time
At sense of discomfort.And if counter-rotating, user is likely to be considered air conditioner abnormal running, further execute shutdown or again
Operation is opened, this will affect user experience.To avoid this case, in the present embodiment, when supply air temperature is higher than set temperature,
Control electric heater is maintained at halted state, when supply air temperature deteriorates to less than set temperature, then controls opening electric heater,
Supply air temperature is promoted to ideal range, keeps the room temperature of air-conditioned room in the preferred range.In above process, such as
Fruit defrost when compressor shutdown and maintain terminate to first effective time-count cycle, at least during this period of time, electric heater is
It is idle, thus, it is supposed that defrosting process maintains 4 minutes or so, then can at least shorten electrically heated starting time eight/
One.On the whole, can guarantee at least to save eighth energy consumption while controlling comfort.
The control method of above-mentioned air conditioner can be effectively prevented room temperature during defrosting and fluctuate widely, and lead to
When crossing monitoring supply air temperature and ensure not have cold wind and blow to user, while can more optimize the starting of electric heater
Between, energy saving, so that control process has better comfort.
It is understood that the growth of outdoor heat exchanger surface temperature is not at the uniform velocity, together during Defrost operation
When, the decline of indoor heat exchanger surface temperature is not at the uniform velocity, but to follow similar parabolical curve and decline yet, lower reduction of speed
Degree does not stop to change.Therefore, if issuing control signal opening electric heater again after detecting that supply air temperature is less than set temperature,
Then there may be the probability of the relatively rapid decline of heat exchanger surface temperature indoor in the delay time of control signal propagation delay, this
It then might have the too low air-supply of temperature in the case of kind and be sent into air-conditioned room, or be blown into user.It is a kind of optional, it keeps away
The control method for exempting from above situation occur is to calculate evenly spaced multiple continuous sampling points when executing Defrost operation process and send
The speed of air temperature decline, selects maximum speed and minimum speed therein, calculates the average speed of maximum speed and minimum speed
Degree, and the preset time that supply air temperature drops to set temperature is calculated according to average speed, and when reaching preset time, that is, control
Opening electric heater processed.In this way, the control signal for controlling opening electric heater is no longer dependent on feedback signal, relatively
For be it is preposition, can it is a degree of balance delayed start-up electric heater avoid room temperature it is too fast decline two control
The control effect of target.
As shown in Fig. 2, the air-conditioner control method in another embodiment is further comprising the steps of: extremely such as Fig. 2 step S20
Shown in step S21, it is first determined whether meeting defrosting condition.If meeting defrosting condition, controlled while executing defrosting process
Indoor unit is run according to wind speed setting gear.This stage, since the heating operation of certain time, room temperature has been carried out
It is basically stable near set temperature, fluctuation is the temperature that a user is comfortable on less, and usually air-supply can also maintain low
Wind file position or mute gear.And the surface temperature of indoor heat exchanger is still much higher than set temperature simultaneously, such as the second setting
Defrosting temperature is typically set in the section of 40 to 45 degree, much higher than air-conditioned room temperature achieved desired by user.In
It blows under the conditions of this, supply air temperature is also higher.The decline that not will lead to indoor air temperature in air conditioned building not only, can also be certain
Temperature loss caused by during defrosting is compensated in degree.It is therefore preferable that control indoor fan is still according to setting
Wind-speed gear operation.As shown in Fig. 2 step S22 to S24, the supply air temperature of air outlet of indoor set is sampled, until supply air temperature is small
When set temperature, opening electric heater is controlled, while preferred control indoor fan is shut down.When electric heater is just switched on, increase
The effect of temperature may be unobvious in a short time, therefore, the too low situation of appearance supply air temperature that can be of short duration, to avoid the occurrence of
This case preferably controls indoor fan shutdown simultaneously.
Air-conditioner control method in another embodiment is further comprising the steps of: as shown in Fig. 3 step S35 and S36, In
After controlling indoor fan shutdown, continue to be monitored air outlet temperature.If air outlet temperature is greater than set temperature, control
Indoor fan restarts to run and be maintained at minimum wind-speed gear.By controlling the power of electric heater, preferably control outlet air
Mouth temperature rises the process greater than set temperature less than 30s again.On the one hand by being higher than the air-supply of set temperature to Indoor Temperature
Degree carries out temperature-compensating, on the other hand, so that air conditioner is restored air-supply as early as possible, thinks that air conditioner is in improper shape to avoid user
State and continually carry out switching on and shutting down operation.Especially in public space, such as hotel air conditioner in use, user often recognizes
It is in malfunction for air conditioner out-of-blast for a long time under heating state, to continually carry out operation control, this may
It will affect the service life of air conditioner.
Air-conditioner control method in another embodiment is further comprising the steps of: such as Fig. 4 step S47, S48, S49-1 and
Shown in S49-2, after control indoor fan restarts to run and be maintained at minimum wind-speed gear, it is first determined whether meeting
Exit defrosting condition.When outdoor heat exchanger coil temperature rises to mesh defrosting target temperature and lasting Defrost operation reaches setting
Between after, then be judged to meeting defrosting condition.Defrosting target temperature can be set as 16-18 degrees Celsius, and the Defrost operation time can be with
It is set as 3.5 to 4.5 minutes.When meeting defrosting condition, Defrost operation process is exited, air conditioner restores normal heating operation.
Further determine whether that receiving user triggers the electric heating operation signal generated, if receiving electric heater operation signal
It is out of service to control electric heater.Electric heater is controlled if being not received by electric heater operation signal to remain operational.I.e.
It is selected by user's further progress.Electric heater operation signal can by operation panel trigger generate, or by personal computer,
Remote server, hand-held device, smart phone and/or wearable device etc. generate by wireless communication.Wirelessly communicating to be
One-to-one communication pattern is perhaps communicated by one or more server communications in local area network or by Cloud Server.
After exiting Defrost operation, a standby signal is preferably fed back by air conditioner, and electric heater operation signal is generated by triggering
Equipment show, to inform that user's electric heater is in running order.
Please referring to Fig. 5 is a kind of air conditioner controlling device 100 provided by the invention, including defrosting judgment module 10, defrosting
Control module 11, sampling module 12, comparison module 13 and electric heating control module 14.
Air conditioner controlling device 100 is mainly used in heating mode.Air conditioner is run in a heating mode, due to outdoor ring
Border temperature is lower, and outdoor heat exchanger meeting frosting needs to defrost in time, avoids the operational effect for influencing air conditioner.Defrosting
Mode is consistent with the prior art, is commutated using four-way valve, and heating mode is changed to refrigeration mode.In cooling mode, temperature compared with
High refrigerant can flow through outdoor heat exchanger, melt the frost layer on outdoor sensor surface.
Wherein, defrosting judgment module 10 is for judging whether current operating conditions meet defrosting condition.Defrosting condition is sentenced
The disconnected judgement mainly to defrost opportunity, that is, need to judge outdoor heat exchanger surface, the especially degree of coil surface frosting, really
It is fixed when to start defrost.Outdoor coil pipe used frosting is affected by many factors, including outside air temperature, water capacity, different systems
The corresponding different refrigerant properties of cryogen type, coil pipe material etc., these factors can all influence speed, the frosting degree of frosting；And
Corresponding different air conditioner type, frosting velocity and frosting degree can influence the normal operation of air-conditioning to some extent.When frosting, due to
The increase of outdoor heat exchanger coil surface frost layer causes the thermal resistance of outdoor heat exchanger to increase, the heat exchange amount of outdoor heat exchanger by
It is decrescence small.When frost layer increases to certain thickness, heat exchange amount just declines rapidly, corresponds to the evaporating pressure and evaporation temperature of air conditioner
Degree will also start to accelerate decline.While outdoor heat exchanger coil pipe pressure and coil temperature decline, the coil pipe temperature of indoor coil
Degree and pressure also decline therewith.Based on the above principles, defrosting condition is set as including time and temperature or time and pressure two
A condition, if outdoor unit continuous operation is to setting defrosting time, and outdoor coil temperature is less than or equal to the first setting defrosting simultaneously
Temperature is judged to meeting defrosting condition when indoor coil pipe is less than or equal to the second setting defrosting temperature.Setting defrosting time can
To be set as outdoor unit continuous operation 35 to 45 minutes, first set defrosting temperature be -5~-8 degrees Celsius, second defrost temperature
It is 40 to 45 degrees Celsius.Setting defrosting time, the first defrosting temperature and the second defrosting temperature can be according to outdoor environment temperature
It is adjusted, such as calls the proportionality coefficient of storage, school is carried out to setting defrosting time, the first defrosting temperature and the second defrosting temperature
Just.
Defrosting control module 11, if meeting defrosting condition, starts to defrost for executing defrosting process.It is a kind of optional
The control process that defrosts includes that compressor, outdoor fan are shut down simultaneously, and the first timer starts timing until first effective timing week
Phase, four-way valve power down commutation.Second timer starts timing until second effective time-count cycle, compressor are opened, start to defrost
Operation.The first effective time-count cycle that was delayed can make the pressure difference between outdoor heat exchanger and indoor heat exchanger reduce, so that pressure
The operation of contracting machine is more steady, avoids causing compressor unnecessary impact.First effective time-count cycle can be set to
30s, second effective time-count cycle can be set as 2 to 5 seconds.
Sampling module 12 is used for when meeting defrosting condition, samples the supply air temperature of air outlet of indoor set.Comparison module 13
For comparing supply air temperature and set temperature.Electric heating control module 14 is used for the control when supply air temperature is less than set temperature
Opening electric heater.
In frosting, due to the influence of frost layer, the surface temperature of outdoor heat exchanger and indoor heat exchanger can decline, but
It is that, since the heating operation of certain time has been carried out, room temperature is basically stable near set temperature, fluctuation is little,
It is the temperature that a user is comfortable on.And the surface temperature of indoor heat exchanger is still much higher than set temperature, such as second sets
Surely defrosting temperature is typically set in the section of 40 to 45 degree, much higher than air-conditioned room temperature achieved desired by user.
It blows under these conditions, supply air temperature is also higher.The decline that not will lead to indoor air temperature in air conditioned building not only, can also be one
Determine to compensate temperature loss caused by during defrosting in degree.If control electric heater is started to work at this time, send
Air temperature can increase sharply, and compressor may be easy to make with it also in shutdown status, the air-supply blow-through of overheat to user at this time
