Specific embodiment
Below with reference to specific embodiment shown in the drawings, the present invention will be described in detail.But these implementation methods are simultaneously
The present invention is not limited, structure that one of ordinary skill in the art is made according to these implementation methods, method or functionally
Conversion is all contained in protection scope of the present invention.
In embodiments of the present invention, specific explaination is done to startup control method of the invention by taking refrigerator as an example, but
It should be noted that involved skill spirit in embodiment disclosed below can alternatively be used the system of other forms
On cool equipment, exemplarily, such as refrigerator.The present invention is input into linear compressor with big power of trying one's best in startup stage, with fast
Speed reduces the generation of noise through the resonant belt of compressor, while avoiding compressor energization moment from producing violent pressure drop.With reference to figure
1, startup control method of the invention includes:
Judge whether refrigerator enters starting state by halted state;
If so, then calling start-up mode, linear compressor is set to run preset time T 1 with preset input power;Preset input power
More than the normal startup input power matched with the linear compressor, less than or equal to the maximum input work of the linear compressor
Rate, also, when start-up mode starts, i.e., it is while compressor is powered, refrigerant system feature or all blocking one is shorter
Preset time T 2.
If refrigerator is entered by halted state when starting, for example, start after pause, then into ordinary control mode.
Specifically, halted state, refers to the state for not having electric current to pass through refrigerator during electronic device in refrigerator.For example, refrigerator
Before first upper electricity, or before being once again powered up after power-off for a long time, or before the energization for the first time of user place.
It is understood that under the halted state, refrigerator cold-storage compartment is consistent with freezing compartment temperature, refrigerator compartment
Temperature can be same or like with room temperature.
Under linear compressor ordinary control mode, start 8-10 times that input power is usually stable operation input power.
Such as linear compressor stable operation input power is 10w, then, the normal startup input power of linear compressor matching can
80w ~ 100w is reached, the preset input power in the present embodiment can be more than 100W, certainly, also can directly be set to maximum input work
Rate, such as 160w.
Usually, the linear compressor of most models is to enter steady-working state behind a minute of upper electricity, so this
Preset time T 1 is at least one minute in embodiment.Certainly, the linear compressor of a small number of models is also not excluded for the one of upper electricity
Steady-working state can just be entered in minute, now preset time T 1 is it can also be provided that be less than one minute.
When refrigerator enters starting state by halted state for linear compressor is provided more than matched normal startup
Input power, the piston stroke of compressor faster increases, rapid pressure drop in housing.In order to avoid compressor pressure drops rapidly
The stability of low process influence part, while compressor is powered, is made by partly or entirely blocking refrigeration system circuit
Compressor air-discharging side pressure drop rate slows down, and each part of compressor reaches dynamic equilibrium during relatively being relaxed at one.Blocking
Time T2 is shorter than the time T1 that compressor under start-up mode is run with foregoing preset input power, to recover cooling cycle system
Unobstructed rear compressor remains to be run with preset input power, fast-refrigerating.Now, although compressor maintains a power higher,
But due to having reached dynamic equilibrium in compressor, the damage to part is smaller.
With reference to Fig. 1, in an embodiment of the present invention, while compressor is powered, close blower fan to reduce refrigeration system
The speed of cold is conveyed to compartment, and opens blower fan after 5 seconds, recover air-supply.
With reference to Fig. 2, in still another embodiment of the process, while compressor is powered, closes in refrigerant loop and set
In the magnetic valve of capillary upstream to block refrigerant passage, and Open valve after 5 seconds, refrigerant recovers to evaporator stream
It is dynamic.
With reference to Fig. 3, in still another embodiment of the process, the air door in air channel is closed to prevent cold air from being circulated to compartment, and 5
Air door is opened after second, the unobstructed of refrigerating circuit is realized.
Further, before start-up mode is called, whether compartment is judged higher than preset temperature, if so, then calling startup
Pattern, if it is not, then entering ordinary control mode.Preferably, the compartment is freezing compartment.The preset temperature is, for example, -5 DEG C.Such as
This, when compartment is consistent with environment, when being in low temperature, such as, in the winter of area of high latitudes, can be avoided shakedown run pattern,
Reduce loss and the energy saving of compressor.
After linear compressor operation preset time T 1, start-up mode is exited, according to temperature in refrigerator compartment and external environment condition
Temperature control linear compressor runs.
With reference to Fig. 4, refrigerator refrigeration system includes being in turn connected to form the evaporator in loop, capillary, magnetic valve 10, condensation

43, capillary includes refrigeration capillary 51 and freezing capillary 53.Refrigeration evaporator 41 and refrigeration capillary 51 are connected, frozen steamed
Hair device 43 and freezing capillary 53 are connected, and both are in parallel again.Magnetic valve 10 by refrigerant branch to refrigeration capillary 51 and/or
Freezing capillary 53, to realize that freezer room institute chilling requirement is distributed.Further, magnetic valve 10 is triple valve, controllable refrigeration
Freeze or refrigerating system difference or collaboration refrigeration.
Refrigerator at least includes refrigerating chamber and refrigerating chamber, the arrangement of the two in the vertical direction.Refrigeration evaporator 41 and refrigeration wind
Road 61 is connected, and refrigerating chamber is led in air channel 61;Refrigerating evaporator 43 is connected with freezing air channel 63, and refrigerating chamber is led in air channel 63, makes cold
Evaporator 41 is hidden only to refrigeration chamber, refrigerating evaporator 43 only freezes to refrigerating chamber.Air channel 61,63 is enclosed by several walls
Passage, the air for evaporator 41,43 to be cooled down imports corresponding compartment.Refrigeration air channel 61 is respectively equipped with cold with freezing air channel 63
Blower fan 81, freezing blower fan 83 are hidden to improve refrigerating efficiency.Air door can be set between air channel 61,63(It is not shown), air door can
Controllably open, to allow refrigerating evaporator 43 and refrigeration evaporator 41 to carry out air exchange.
Refrigerator also includes computer board, for judging whether refrigerator by halted state enters starting state, and control straight line
The mode of operation of compressor.
If so, then calling start-up mode, control linear compressor runs preset time T 1 under preset input power.
Wherein, Preset Time uses single-chip microcomputer timing.Preset input power with the linear compressor more than matching just
Often start input power, less than or equal to the maximal input of the linear compressor.
Computer board is also controlled when start-up mode starts, and cooling cycle system at least partly blocks preset time T 2.T2<
T1。
Specifically, computer board can control blower fan 81 and/or 83 to close 5 seconds while compressor is powered, it is then turned on.
The magnetic valve 10 in refrigerant loop can also be controlled to close 5 seconds, be then turned on;Or control air door closes 5
Opened after second.
Further, the backed off after random start-up mode of preset time T 1 is run, according to temperature in refrigerator compartment and external environment condition temperature
Degree control linear compressor operation.
Specifically, temperature can be used to control the start and stop of the linear compressor in refrigerator compartment.Ambient temperature can divide
It is multiple continuous temperature ranges, the operational factor that each temperature range sets linear compressor is corresponded to, in current refrigerator compartment
Linear compressor is transported according to corresponding operational factor when temperature is more than target temperature and is more than fiducial temperature to the temperature difference of target temperature
OK.
