The warm area compartment refers to the independent cooling region in refrigerator, and the evaporator may be mounted at the independent cooling area In domain, evaporator can not also be set in certain warm area compartment, and in process of refrigerastion, pass through the pipelines such as air passage, pore Structure obtains cold from other warm area compartments with evaporator, so as to complete the refrigeration in this warm area compartment.

What the pre-set target temperature control parameter was characterized can be an actual temp, for example, 5 DEG C, 10 DEG C etc..When So, it is described set target temperature control parameter characterization can also be an actual temp scope, for example, 10 DEG C to 13 DEG C, -12 DEG C To -6 DEG C etc..Also, the pre-set target temperature control parameter can be user voluntarily set need the warm area indoor Indoor the reached compartment temperature of temperature or the warm area of system default reached, and or pass through other temperature The compartment temperature of section room judges indoor compartment temperature that should reach of the warm area, etc. according to preset rules.

The controller 106 can be specifically general central processing unit (CPU), can be application-specific integrated circuit (English：Application Specific Integrated Circuit, referred to as：ASIC), can be that one or more is used for The integrated circuit for controlling program to perform.

Further, the refrigerator can also include memory, and the quantity of memory can be one or more.Memory It can include read-only storage (English：Read Only Memory, referred to as：ROM), random access memory (English：Random Access Memory, referred to as：) and magnetic disk storage RAM.

In actual mechanical process.The controller can be by controlling the electromagnetism being connected respectively with N number of evaporator Valve opening and closing is so as to control refrigerant to flow through the order of N number of evaporator and flow through the time of N number of evaporator, certainly also Can be by controlling the rotating speed of compressor and the operating power of condenser to control speed of the refrigerant when flowing through evaporator With the condition conversion speed of refrigerant, it is finally reached and controls the refrigeration order of each warm area compartment and the purpose of cryogenic temperature.

For example, a refrigerator includes three warm area compartment M1, M2, M3, M1 and M2 share an evaporator a1, and M3 has Independent evaporator a2, the corresponding pre-set target temperature control parameter of three warm area compartments are -15 DEG C, -5 DEG C and 6 DEG C, Controller can also determine that the corresponding pre-set target temperature scopes of M1 are -18 DEG C to -12 DEG C, M2 pairs according to above three parameter The pre-set target temperature scope answered is -8 DEG C to -2 DEG C, and the corresponding pre-set target temperature scopes of M3 are 3 DEG C to 9 DEG C.Therefore, control Device can also control refrigerant to make the indoor temperature of each warm area compartment reach corresponding pre-set target temperature scope Flow time more flows through speed and passes through a1 faster, and less flows through the slower process a2 of speed with respect to flow time, so that Respectively reach the refrigeration demand of three warm area compartments.

As it can be seen that controller can be controlled based on the pre-set target temperature of the M warm area compartment in actual mechanical process Parameter, by control the various ways such as compressor, condenser and solenoid valve control refrigerant the approach for flowing through evaporator, Time and speed, so as to achieve the purpose that to control the indoor temperature of each warm area in refrigerator.Due in actual mechanical process It is middle there are it is a variety of by way of controlling compressor, condenser and solenoid valve with to each warm area compartment system in refrigerator Cold, succinct in order to illustrate book does not just enumerate herein.

It can be seen from the above that the technical solution in the embodiment of the present application can the goal-selling temperature based on the M warm area compartment Control parameter is spent, and path and stream are flowed through to the compressor and the refrigerant for being output to N number of evaporator in various ways It is controlled through the time, so that each warm area compartment in the M warm area compartment is in pre-set target temperature, so as to avoid The existing control rule based on heterothermic refrigerator is only capable of carrying out alternating temperature control for specific alternating temperature compartment, can not be adapted to user couple The personalized customization demand of different warm area compartment demand combinations, by default parameter and method, intelligent sentences the control rule The demand of disconnected user and setting, make refrigerator be continuously under preferably operating mode and run, and have and improve applicability and lifting user The technique effect of impression.

Alternatively, the controller 106, to be obtained and described Q steaming based on the pre-set target temperature control parameter The one-to-one Q target evaporating temperature value of device is sent out, at least one warm area compartment in the M warm area compartment is determined as one A temperature control region, is obtained P temperature control region, is ranked up the P temperature control region based on the Q target evaporating temperature value First ray is obtained, controls the solenoid valve so that the refrigerant flows through and the P temperature controlled region according to the First ray The corresponding evaporator in domain, with according to the First ray to each temperature control region system in the P temperature control region It is cold, wherein, the target evaporating temperature value belongs to right with it for the indoor temperature of each warm area in the temperature control region During the pre-set target temperature scope answered, provide the estimated temperature value reached of evaporator of cold for the temperature control region, P be less than Positive integer equal to M.

Since in actual mechanical process, the mesh of the evaporator of cold is provided for one or more of refrigerator warm area compartment Mark evaporating temperature value can be it is same or like, therefore, can in some warm area compartment in refrigerator in order to save application cost To set independent evaporator, evaporator can not also be set.Being also based on above application principle at the same time will be more in refrigerator A warm area compartment sets according to a pre-defined rule and is divided into same temperature control region.For example, can be by between target evaporating temperature value Multiple evaporators of the difference in preset threshold range corresponding to the warm area compartment of cold be provided be divided into a temperature control region, Warm area compartment with evaporator and warm area compartment of the part without evaporator can be divided into a temperature control region, when So, above-mentioned a variety of dividing modes are can be combined with, by the difference between the warm area compartment with evaporator and target evaporating temperature value Warm area compartment of part of the value in preset threshold range without evaporator is divided into a temperature control region, passes through transporting cold wind Or the mode of refrigerant, freeze to multiple warm area compartments in same temperature control region, multiple evaporation device wheels can also be used Flow mode freezed to same temperature control region, etc..As it can be seen that there are a variety of division temperature control regions in actual mechanical process Mode, succinct in order to illustrate book just do not enumerate herein.

The target evaporating temperature value can be obtained based on the pre-set target temperature control parameter according to preset rules Take.For example, a refrigerator includes two temperature control regions F1, F2, F1 includes warm area compartment M1 and M2, F2 including between a warm area The corresponding pre-set target temperature control parameter of room M3, M1, M2, M3 is -11 DEG C, -8 DEG C and 5 DEG C, and controller also can root Determine that the corresponding target evaporating temperatures of F1 are -20 DEG C according to a preset function correspondence according to above three parameter, F2 is corresponding Target evaporating temperature is -10 DEG C.

Simultaneously as in refrigerator each temperature control region thermic load parameter, that is, each warm area compartment in temperature control region Heat leak sizes values when interior constant temperature is in corresponding pre-set target temperature scope in the temperature control region.And Under normal conditions, refrigerator carries out conversion refrigeration between thermic load parameter value differs less warm area compartment, it runs in adjustment Change during state is smaller, can not only realize preferable regulated efficiency, and can realize less change of power consumption.Therefore, exist The P temperature control region can be ranked up based on the Q target evaporating temperature value in actual mechanical process and successively into Row refrigeration, so that reaching makes refrigerator be in the adjustment process of refrigerastion releived in proper order, is conducive to keep the steady operational status of refrigerator, Extend the service life of each component of refrigerator.

As it can be seen that technical solution in the embodiment of the present application can also be obtained by the pre-set target temperature control parameter with The one-to-one target evaporating temperature in temperature control region, so that it is determined that the refrigeration order in each temperature control region in refrigerator, finally makes Obtain refrigerator and be in the adjustment process of refrigerastion releived in proper order, be conducive to keep the steady operational status of refrigerator, have and improve refrigerator Freeze regulated efficiency and the technique effect of the service life of extension each component of refrigerator.

Alternatively, controller, three-temperature-zone compartment and four-temperature region compartment are determined as a temperature control region, its In, the target evaporating temperature value of the evaporator of cold is provided for three-temperature-zone compartment and is provided for four-temperature region compartment Difference between the target evaporating temperature value of the evaporator of cold obtains the P temperature control region within predetermined threshold value, And/or it is determined as a temperature without the warm area compartment of evaporator and a warm area compartment with evaporator by some or all Region is controlled, and then obtains the P temperature control region.

In actual mechanical process, if multiple warm area compartments provide cold multiple evaporators its target evaporating temperatures it Between difference within predetermined threshold value, the indoor temperature that the multiple warm area compartment finally needs to reach is also in preset temperature difference Within.It is therefore possible to use a small amount of evaporator provides cold for the multiple warm area compartment at the same time, multiple evaporations can also be used Device wheel stream provides cold for the multiple warm area compartment.So as to realize further reduction power consumption and reduce application cost Purpose.

On the other hand, can also be by one or more warm area compartments without evaporator and a temperature with evaporator Section room is arranged to a temperature control region, can be by way of pipeline, air passage air-supply, from evaporation during refrigeration The warm area compartment of device achievees the purpose that refrigeration to other warm area compartment transporting cold winds.

Certainly, can not also will have evaporator using with reference to by the way of above two method in actual mechanical process One or more warm area compartments with being arranged to a temperature control region, and the temperature controlled region with a warm area compartment of evaporator Difference between the pre-set target temperature control parameter of each warm area compartment in domain is within predetermined threshold value.Due to can be at the same time Both the evaporator for ensureing to use quantity to be less than warm area compartment quantity freezes for multiple warm area compartments, and needed for multiple warm area compartments The target temperature reached is close, and cooling time is close, therefore can realize and further reduce unnecessary power consumption.

As it can be seen that the technical solution in the embodiment of the present application can be by the way that the difference between target evaporating temperature value be being preset Multiple warm area compartments within threshold value are determined as a temperature control region, and/or will not have evaporator in the M warm area compartment Warm area compartment and a warm area compartment with evaporator are determined as the mode in a temperature control region, reach reduction in process of refrigerastion The quantity of the middle evaporator for needing to be in operating status, and reduce the purpose of cooling time.Therefore with further effective Save the technique effect of refrigerator power consumption.

Further, the controller, to be obtained and the P temperature controlled region based on the Q target evaporating temperature value One-to-one P thermic load parameter is distinguished in domain, and the P thermic load parameter is descending or ascending according to value Order, which is ranked up, obtains thermic load sequence, determines warm correspondingly with each thermic load parameter in the thermic load sequence Control region is ordered as the First ray, wherein, the thermic load parameter is the temperature controlled region under current refrigerating state When the indoor constant temperature of each warm area in domain is in corresponding pre-set target temperature scope in the temperature control region Heat leak size.

In actual mechanical process, the thermic load parameter corresponding with temperature control region not only evaporates temperature with corresponding target Spend it is closely bound up, and with current refrigerator local environment temperature and with the relevant each parameter of the heat leak of refrigerator, such as foam Layer thickness, door weather strip length, the parameter such as power of associated heat component are directly related.Different thermic load parameters are then meaned The refrigerator different states residing when pair temperature control region corresponding from the thermic load parameter is freezed.Therefore, obtain accurate State when true thermic load parameter could freeze refrigerator pair temperature control region corresponding with the thermic load parameter carries out accurate Really assessment.

In actual mechanical process can will corresponding with each temperature control region thermic load parameter carry out it is descending or by small To big sequence, so as to determine the refrigerating state of refrigerator according to actual thermic load parameter, realize refrigerator incremental Refrigerating state adjustment process.

In actual mechanical process specifically can according to the corresponding target evaporating temperature value in each temperature control region to it is other related Parameter obtains the thermic load parameter corresponding to each temperature control region using preset algorithm.For example, when first temperature control region includes Warm area compartment A, warm area compartment B and warm area compartment C, and the target evaporating temperature value of A is -9 DEG C, the target evaporating temperature value of B for - 11 DEG C, certainly, can be to the model of each evaporating temperature in actual mechanical process when the target evaporating temperature value of C is -14 DEG C Enclose and be any limitation as, and the difference between the temperature residing for the evaporator being guaranteed in same temperature control region is less than predetermined threshold value. Then finally definite target can be taken according to preset function relation according to the corresponding temperature value of three target evaporating temperature values at this time Evaporating temperature value be -18 DEG C, then by obtain current refrigerator local environment temperature and with the relevant each parameter of the heat leak of refrigerator, Such as power of depth of foam, door weather strip length, associated heat component etc. is counted using weighting scheme, so as to obtain Thermic load parameter corresponding with -18 DEG C is obtained, namely is that of obtaining thermic load parameter corresponding with first temperature control region.Certainly, in reality Thermic load parameter corresponding with each temperature control region can also be obtained in the operating process of border in several ways, in order to illustrate book Just do not enumerate herein succinctly.

As it can be seen that the technical solution in the embodiment of the present application can also be by according to the corresponding thermic load parameter in each temperature control region To control the control refrigerant to flow through the order of each evaporator, so as to play the operating status of accurate definite refrigerator, make ice Case freezes according to the adjustment state of incremental formula, therefore has the refrigeration regulated efficiency for further effectively improving refrigerator, Save the technique effect of refrigerator power consumption.

Further, the controller, to the first thermic load parameter acquiring based on the first temperature control region and described the The corresponding refrigerating capacity in one temperature control region, the refrigerating capacity are the unit time interior produced cold in the first temperature control region Size, in the evaporator during the refrigerant flows through the first temperature control region, control the rotating speed of the compressor for institute State the corresponding first rotating speed operation of refrigerating capacity.

In actual mechanical process, the refrigerating capacity produced cold under specific operation for the refrigeration system in refrigerator Size.For example, the refrigerating capacity can refer to be produced in refrigerating chamber when the compressor of refrigerator is under 150w power operating states Raw cold, the refrigerating capacity may also mean that when the overall power consumption of refrigerator is under 200w power operating states in refrigerating chamber Caused cold, etc..

As it can be seen that there are certain proportion relation, i.e. COP values for the power consumption of the refrigerating capacity and the practical power of refrigerator (Coefficient Of Performance, refrigerating efficiency).Simultaneously as thermic load parameter is in current refrigerating state Under, the temperature control region is continuously in heat leak size during corresponding pre-set target temperature, therefore, the refrigerating state Also include referring to current power supply power consumption.

In order to ensure to complete refrigeration, under normal circumstances, it is necessary to make the refrigerating capacity in each temperature control region be more than thermic load parameter. And the operation principle based on refrigerator, namely the start and shutdown of refrigerator can be produced so that the temperature province in each temperature control region is steady It is fixed, and the start of refrigerator can then correspond to another parameter with shutting down：Homes Using TV, the Homes Using TV are in one for compressor continuous In secondary open state and total duration in a holding state, duration during in open state accounts for the ratio of total duration.Cause Average refrigerating capacity in each temperature control region in a cycle, in actual mechanical process, can be approximately equal to thermic load ginseng by this Number, and refrigerating capacity of each temperature control region in refrigerating operaton should be greater than actual heating load parameter, and refrigerating capacity and actual heating load Size of the difference between parameter depends on wishing the size of the Homes Using TV reached.
