The temperature of the high temperature load in refrigerator is stored to be reduced to indoor temperature value between refrigerator 1, it is necessary to discharge
Heat out, so that it is very important for the computing system.Heat Calculation formula in the computing system is Q=c
M (t1-t2), wherein c is the specific heat capacity of load, and m is the quality of load, and t1 is the temperature value of food, and t2 is indoor between refrigerator 1
Temperature value.By taking high temperature food as an example, in the actual operation process, the value mode of the specific heat capacity c of food are as follows: will often pick and place
Food be averaged after for certain value, instead of the foods of all deposit refrigerators 1；The quality m of food is intelligently known by detection system
It does not detect；The temperature value t1 of food can replace (such as according to the ambient temperature value or constant certain value surveyed: 25 DEG C) by room temperature
Or the temperature that can also be used when infrared temperature sensor is stored in refrigerator 1 to food carries out precise measurement；Indoor temperature between refrigerator 1
Angle value t2 is obtained by the temperature sensor 15 detection.
Cooling capacity compensation device of the invention includes that the difference there are two types of embodiment, between two kinds of embodiments is: real
The temperature value t1 for applying the food in example one is that temperature when being stored in refrigerator 1 to food using infrared temperature sensor is accurately surveyed
It measures and obtains, accurately calculated with the heat to high temperature load, to accurately control the working time of compressor 51, cooling capacity
It is lost smaller；And the temperature value t1 of the food in embodiment two is replaced by room temperature, needs not move through precise measurement, to control roughly
The working time of compressor 51 processed, but to will lead to cold consumption larger for such design.
The working principle of the compressor 51 is the prior art, is no longer illustrated in this.
Cooling capacity compensation method applied to refrigerator 1 of the invention, mainly comprises the steps that
S1, provide a detection system, with when refrigerator 1 is stored in high temperature load to the volume of high temperature load and/or quality into
Row detection；
S2, a computing system is provided, to carry out heat Calculation according to the volume of high temperature load and/or quality；
S3, a control system is provided, it is cold required for reducing load temperature to be predicted according to the calculated result of computing system
Measure and control the working time of 1 refrigeration system of refrigerator.
As shown in Fig. 2, when for using the prior art and cooling capacity compensation device of the invention, indoor temperature between refrigerator 1
The curve of cyclical fluctuations compares figure.From this figure, it can be seen that after storing high temperature load, using the ice of cooling capacity compensation device of the invention
Indoor temperature fluctuation is less than indoor temperature fluctuation between the refrigerator 1 using the prior art between case 1, while evaporator 13 is averaged
Temperature again smaller than the evaporator 13 of existing general refrigerator mean temperature, to reduce energy consumption.
In conclusion refrigerator 1 of the invention is by being provided with cooling capacity compensation device in an interior, thus negative being put into high temperature
After load, which can predict required for reducing high temperature load according to the volume and/or quality of high temperature load
Cooling capacity, and the working time of refrigeration system is controlled in advance, to can not only reduce the fluctuation of 1 room temperature of refrigerator, simultaneously also
The mean temperature of evaporator 13 can be reduced, energy consumption is reduced.
