Embodiment one
Described cooling fluid, at least containing part water, adopts the method for ice sheet cold-storage, makes cooling fluid maintain constant temperature.
As shown in Figure 2, the method for described ice sheet cold-storage is:
Refrigeration system starts and freezes to the perisporium of the cooled containers of splendid attire cooling fluid, and make coolant temperature drop near freezing point, the internal perisporium of cooled containers starts to freeze;
Along with the perisporium carrying out cooled containers of refrigeration forms ice sheet gradually, when ice layer thickness is increased to certain thickness, refrigeration system stops refrigeration, and cooling fluid and ice sheet maintain the temperature close to freezing point in cooled containers;
Along with the cooling to tank/bottle drink, ice sheet melts gradually, when ice sheet is reduced to certain thickness, again starts refrigeration system; Circulate successively, maintenance coolant temperature maintains the temperature near freezing point.
Cooling fluid needs the article of cooling for cooling, as tank/bottle drink, if the temperature of cooling fluid is not fixed, accurately can not control the temperature that tank body beverage is cooled to, so cooling fluid maintenance constant temperature is quite important to the control of chilling temperature, if also have simple set temperature sensor to detect the start and stop that coolant temperature controls refrigeration system, refrigeration system needs frequent start-stop, have a strong impact on the service life of refrigeration system, refrigeration system mostly is compressor cooling simultaneously, during compressor start, also has very large noise.
The present invention is ingenious when utilizing solid-liquid, absorbs or release between heat energy and interior energy to transform, and temperature-resistant principle, controlled cooling model liquid, under solid-liquid state, can maintain the long-time constant temperature of cooling fluid.Evenly freeze to cooled containers perisporium, making, cooled containers internal perisporium freezes forms ice sheet, and inner isothermal liquid can as cooling solution.Use the stop frequency of the reduced refrigeration system of ice sheet cold-storage, extend the service life of refrigeration system, reduce frequency noise.
The stop frequency frequency of refrigeration system reduces simultaneously, the number of times of start and stop in the set time reduces, any electric elements number of times of start and stop within service life is fixing, so the number of times of start and stop in the set time reduces, the life-span of refrigeration system can be extended, especially compressor, during compressor start, have noise, the initiation culture reducing compressor can also reduce noise pollution.
Control the method for refrigeration system start and stop: described ice layer thickness is by ice layer thickness sensor direct-detection, and the method is also the most direct method, ice layer thickness sensor is set in cooled containers inside and detects ice layer thickness sensor.Ice layer thickness sensor, according to resistance, electric capacity, the isoparametric difference of conductance in the process of water freezing and ice-out, can judge ice layer thickness, or the sensor such as laser range sensor or thickness transducer also can be adopted to detect ice layer thickness.
During refrigeration, when cooled containers internal perisporium has an ice sheet, ice layer thickness sensor detects ice layer thickness, and when ice layer thickness meets or exceeds maximum set value, refrigeration system stops refrigeration;
After stopping refrigeration, when ice layer thickness sensor detect ice layer thickness reach or lower than minimum setting value time, refrigeration system starts refrigeration, and width or the diameter of the maximum set value of ice layer thickness and minimum setting value and described cooled containers are corresponding.
In the process of refrigerastion of cooling fluid, width or the diameter of the maximum set value of ice layer thickness and minimum setting value and described cooled containers are corresponding.When cooled containers is larger, it is relative large that maximum set value and the minimum setting value of ice layer thickness should be arranged, when cooled containers is less, it is relative less that maximum set value and the minimum setting value of ice layer thickness should be arranged, internal liquid heat absorption during such guarantee cooling fluid cooling tank body beverage, when temperature does not also have enough time to raise, just absorbed by during ice-out, and the initial stage of freezing also needs certain hour, cooled containers is larger, the cold needed is more and the time is longer, this stage also needs remaining ice sheet to maintain the constant temperature of cooling fluid, therefore the width of the maximum set value of ice layer thickness and minimum setting value and described cooled containers or diameter match.
The maximum set value of preferred ice layer thickness and the width of minimum setting value and described cooled containers or diameter proportional, the maximum set value of described ice layer thickness is in the width of cooled containers or 1/50 ~ 1/10 scope of diameter, and the minimum setting value of described ice layer thickness is in the width of cooled containers or 1/80 ~ 1/50 scope of diameter.
Also have a kind of method controlling refrigeration system start and stop: the temperature being detected cooling fluid in cooled containers by temperature sensor, by timer detection time, the time of being down to freezing point by detecting coolant temperature judges ice layer thickness.
During refrigeration, the temperature of cooling fluid reduces gradually, and after temperature sensor detects that cooling solution is down to freezing point, timer starts timing, and after reaching setting-up time T1, ice layer thickness meets or exceeds maximum set value, and refrigeration system stops refrigeration;
After stopping refrigeration, in certain hour, the temperature of cooling fluid maintains near freezing point, and after temperature sensor detects that cooling solution increases to over freezing point, start timing, after reaching setting-up time T2, ice sheet all melts, and refrigeration system starts refrigeration again.The method needs the power of refrigeration system comparatively large, and the time expand at refrigeration initial stage is shorter.
In the process of refrigerastion of cooling fluid, width or the diameter of setting-up time T1 with T2 and described cooled containers are corresponding, and width or the diameter of setting-up time T1 and T2 and described cooled containers are proportional.
During refrigeration, refrigeration system is at least evenly freezed to cooled containers perisporium, is absorbed the part cold of cooled containers and refrigeration system radiation by a cooling-storage structure, when ice sheet melts or coolant temperature rises, this part cold discharges, and reduces the frequency that refrigeration system starts.Increase the utilization rate of cold to the full extent, reduce the waste of cold.Outermost layer can also arrange heat-insulation layer, stops that external temperature is on the impact of inner constant temperature.
