Description
The interests of the korean patent application that proposes in Korea S Department of Intellectual Property on August 11st, 2005 2005-0073742 number are advocated in this application, and it is for reference that the disclosure content of described application is incorporated this paper at this.
Technical field
The present invention relates to a kind of operation control method of refrigerator, more specifically, relate to a kind of when surrounding air is in low temperature, can prevent from refrigerating chamber, the to carry out unnecessary cooling and the operation control method of refrigerator of heating operation.
Background technology
Refrigerator is the equipment that the cooling air that produces by utilizing in the cooling circuit makes various food long-period freshness preservings.Refrigerator generally includes and is used for frozen food is stored in the refrigerating chamber that is lower than under the solidification point (freezingtemperature), is used for chilled food is stored in the cooling circuit that is higher than the refrigerating chamber under the solidification point and is used to cool off refrigerating chamber and refrigerating chamber.
Fig. 1 is the schematic diagram of the cooling circuit 10 of usually said independently cooling means, and as an example of cooling circuit 10, wherein evaporimeter 41,51 and blower fan 43,53 are arranged in refrigerating chamber 40 and the refrigerating chamber 50 independently.Referring to diagram, cooling circuit 10 be provided with the refrigerant of high temperature and low pressure be compressed into the refrigerant of one of high temperature and high pressure compressor 11, make condenser 12 that the refrigerant that compressed condenses, the refrigerant that has condensed that makes low temperature and high pressure carry out the capillary (capillarytube) 13 of adiabatic expansion and be arranged on refrigerating chamber 40 and refrigerating chamber 50 in evaporimeter 41,51, described evaporimeter evaporates the refrigerant that has expanded respectively, and therefore produces the cooling air.Cooling circuit 10 further is provided with evaporimeter 41,51 cooling air supplies that produced to the blower fan 43,53 of refrigerating chamber 40 and refrigerating chamber 50 and be used for refrigerating chamber heater 45 and refrigerating chamber heater 55 that evaporimeter 41,51 is heated and defrosts.
The operation that now explanation is had the cooling circuit 10 of above-mentioned configuration.At first, refrigerating chamber 50 and refrigerating chamber 40 are configured to remain on and have preset upper limit temperature and predetermined lower limit temperature controlling temperature range.When the internal temperature of refrigerating chamber 50 or refrigerating chamber 40 is outside the scope of control temperature, compressor 11 can running so that evaporimeter 51 or 41 produces the cooling air.Usually, when the heat load of compressor during, start or close compressor 11 according to the internal temperature of refrigerating chamber 50 greater than the heat load of refrigerating chamber 40.
Compressor 11 when conforming to a predetermined condition (for example, the internal temperature of refrigerating chamber 50 is greater than ceiling temperature) under the situation about turning round, unless the internal temperature of refrigerating chamber is during less than lower limit temperature, the cooling of refrigerating chamber 40 is carried out with the cooling of refrigerating chamber 50 usually.Therefore, in many cases, when compressor 11 entrys into service, the cooling down operation of refrigerating chamber 40 begins.This is the frequency for the individual operation that reduces the compressor 11 that is used for refrigerating chamber 40, and the once running by can be by compressor 11 simultaneously refrigerated compartment 40 and refrigerating chamber 50 form cool cycles operator scheme clocklike, thereby increase the operational stability of cool cycles 10.
Yet, in traditional operation control method of refrigerator, have a shortcoming.Particularly, as the temperature difference T1 between the internal temperature of the temperature of surrounding air and refrigerating chamber 40 during less than the temperature difference T2 between the internal temperature of refrigerating chamber 40 and refrigerating chamber 50, because the temperature of the surrounding air around the refrigerator is very low, so the heat of refrigerating chamber 40 is sent to refrigerating chamber 50, thus the sub-cooled of generation refrigerating chamber 40.
Simultaneously, have the conventional refrigerator that adopts a kind of method, described method increases the internal temperature of refrigerating chamber 40 by use refrigerating chamber heater 45 and refrigerating chamber blower fan 43 when existence makes refrigerating chamber 40 supercooled risks.
Yet, in traditional refrigerator, determining whether to make 45 runnings of refrigerating chamber heater according to the surface temperature of evaporimeter 41, wherein said evaporator surface temperature is in very low temperature after the running of compressor 11 stops just.Therefore, refrigerating chamber heater 45 is running very continually, and this is a shortcoming.In addition, because even refrigerating chamber heater 45 arrives unnecessary heating refrigerating chamber 40 (promptly when the temperature height of surrounding air, Δ T1 〉=Δ T2) time or the internal temperature of refrigerating chamber 40 is high also can turn round when not having the refrigerating chamber of making 40 supercooled risks, so the internal temperature of refrigerating chamber 40 can raise with being out of favour.
Furthermore, there is another shortcoming.Because can causing, the internal temperature of the refrigerating chamber 40 that raises carries out cooling down operation once more, and the surface temperature of the evaporimeter 41 that descends because of cooling down operation causes 45 runnings of refrigerating chamber heater, so can repeat unnecessary cooling down operation and heating operation in the refrigerating chamber 40 in each cool cycles.
Therefore, in traditional operation control method of refrigerator, there are various shortcomings.For example, owing to cause when ambient air temperature is in low-temperature condition when being in the condition of high temperature specific consumption more energy mutually because of repeating unnecessary cooling and heating operation when the low-temperature condition.
Summary of the invention
