Describe in detail
The object of the invention is applied to any refrigerating equipment, and wherein the temperature adjustment of refrigerated storage compartment is by electronic controller
Control.In common document, a part for equipment, the temperature adjustment of refrigerated storage compartment is generally by temperature control system pipe
Reason, and managed by monitoring one or more the characteristic temperature trend measured by one or more hygrosensors.So
Temperature control system can pass through to supervise related to part (compressor, vaporizer, condenser, fan, see Fig. 1) and at which
The temperature of the lower adjustment equipment of control.
The input of such temperature control system is defined as：
" regulation hygrosensor " in by using the refrigerated storage compartment of the equipment that is placed on controls the temperature of article；
Evaporator temperature is controlled by using " the vaporizer detector " that be placed on evaporator surface.This input is warm
Degree control system is used to keep vaporizer and the high efficiency into the heat exchange between the air of refrigerated storage compartment.This input
Another kind of purposes (and also being performed by temperature control system) be to avoid ice accumulation on evaporator surface.
By using the condenser detector control condenser temperature being placed on condenser surface.This input by with
The high efficiency of the heat exchange between the surrounding air around holding condenser and equipment.
Additionally, some other functions, some parts of general knowledge document can be included in temperature control system：These work(
The maximum temperature for checking the maximum temperature of article and reaching due to condenser or compressor delay activation can be could be for
Security function, or other functions that those skilled in the art can realize.
Recently, some are had been incorporated into regard to the function of energy optimization.Some of which is related to manage thawing cycle.
The existing knowledge document of the optimization method that description is thawed can be summarized as follows：
Passive approach：Stop performing defrosting by compressor cycle.
Active method：By using steam, also referred to as circulation reversion, or using electrical heating elements performing solution
Freeze.
In both above situation, target is to melt the ice being present on evaporator surface.It is explained below and melts ice
Indirect effect：The quantity of position and the ice for existing depending on vaporizer, raises the temperature of refrigerated storage compartment.It is former for this
Cause, first requirement are the persistent period of optimization thawing cycle and timetable to limit the rising of refrigerated storage compartment temperature.
There are different modes to obtain this result：
Using special hygrosensor, vaporizer detector, once with check the temperature on evaporator surface and
The temperature value of measurement exceedes the operation that preset value just interrupts thawing cycle.This simple solution is not to thawing cycle
Persistent period and timetable are optimized, because it does not account for the actual quantity of ice present on evaporator surface.
The trend of evaporator temperature curve is analyzed to detect ice-out state, referred to as potential heated condition, and only
Just interrupt the operation of thawing cycle at the end of this melting state.It is this electronics thaw (active defreezing method) in the case of
The method that can be operated very well, does not adapt to all those situations using passive defreezing method (compressor shuts down)
In.
EP0328151B1 discloses the situation of the existing method for thawing cycle.In such solution, pass through
Thawing cycle is completed using the electrical heater elements of active drive, until potential heated condition terminates, and impulse modulation is straight
Reach end thawing condition.With prefixed time interval analyze evaporator temperature trend with detect potential heated condition end and
Terminate thawing condition.

On equipment using passive defreezing method：
Relative analyses evaporator temperature trend and obtained by the accurate driving method of compressor and evaporator fan
Adjust temperature.The difference adjusted between temperature and evaporator temperature is continually monitored to detect when that reaching default end thaws
Condition.
Start to start thawing cycle using any " energy saver mode ".This allows controller using due to from " routine
Pattern " changes the temperature caused to " energy saver mode " and increases, and this thermal gradient is used at the end of any thawing cycle
To reduce the demand to additional energy, to reach SETPOINT temperature.
Another kind of method of obtain energy-conservation is the working condition of equipment of the basis under control using different
SETPOINT.For example, there are some solutions from state of the art here：
Change temperature SETPOINT according to Preset Time table.This needs additional hardware, is referred to as real-time clock, and which must
Must be manually set and depending on the business hours for selling shop.If sell shop change it business hours or if
Time seasonally changes, then this solution does not reach desired result.
EP1540438B1 discloses a solution, and which uses different SETPOINT, it is allowed to dynamic produce and more
New time interval.Realization is used for from multiple signals of " using sensor (such as door trip or vibrating sensor) " to be in
The use pattern of the equipment under control.By this way, when some detected on equipment are movable, it is possible to use required
SETPOINT, and using the different temperatures value higher than SETPOINT temperature between craticular stage.This solution needs to make
With at least one " using sensor ", even if these sensors cause extra raw material and production cost for manufacturer.
The present invention is proposed and avoids any " using sensor " but the probability of the advantage for still providing energy-conservation.The present invention
A kind of method for disclosing analysis temperature change rather than analytical activity signal (from what is produced using sensor).With this side
Formula, simplifies production technology and ultimate cost is reduced for manufacturer.Replace at short notice and in a straightforward manner
It is also possible to change or repair any equipment (refrigerating equipment) deposited in the art.Another aspect of the present invention
It is to be incorporated in identical control system using different power-economizing methods and them, is preferably carried into execution a plan.
For recognizing the analysis model in energy-conservation period
Can be in the following operational mode for distinguishing control system (Fig. 1) between the two and the target of the present invention：
" normal mode "：This operational mode is identified as the regulation temperature of refrigerated storage compartment equal to SETPOINT's
Period
" energy saver mode "：This operational mode is identified as the regulation temperature of refrigerated storage compartment higher than SETPOINT's
Period.
The control system of the present invention uses electronic controller (C of Fig. 1), and what its offer came used in comfortable refrigerating equipment can
With the data collection of hygrosensor (A, B of Fig. 1).This electronic controller is converted to data set the data collected, and with
Post analysis this data sets.Analysis result is to change automatically refrigerating equipment according to available output (E, F, G and the H of Fig. 1)
The analysis model of operational mode.
Generally, control system object of the invention is consisted of：
In being placed on refrigerated storage compartment and be used to adjust for temperature and detection any temperature change one or more
Hygrosensor (A of Fig. 1, B).The temperature change measured by hygrosensor is classified as follows：
- short-term, changes, and which is defined as the temperature change of moment.It is due to the equilibrium-like of equipment in control
Any change of state and cause.This is likely due to any padding of opening door or refrigerated storage compartment and causes
's.
- middle period change, which is defined as slow temperature change.It is because of equipment in control towards week
The radiating in collarette border or subsequent day and night temperature change are caused due to seasonal temperature change.
One in these hygrosensors can be placed on evaporator surface, to measure evaporator temperature and control
Any thawing cycle.
Electronic controller (C of Fig. 1) can be collected, analyzes, classifies, processes and be stored from usable temp detector and detected

Under all elements equipment, needing energy, part, such as the compressor, fan, lamp and heating element (Fig. 1 in equipment
E, F, G, H).By data set process, and by using internal algorithm, electronic controller can set up the analysis mould of operation
Type.By using this model, electronic controller can make the function of equipment be applied to any particular case, in business temperature and section
Optimum optimization can be provided between requiring.By this way, analysis model can allow for equipment and run in two different situations：
" energy saver mode " above-mentioned and " normal mode ".Any time for detecting temperature change " is often identified as by analysis model
Scale formula ", and any time for not having detection temperature change is identified as into " energy saver mode ".When in " energy saver mode "：
- SETPOINT will be moved into the value higher than business SETPONT and rely on preset value.
- in the beginning of any " energy saver mode ", thawing cycle (Fig. 4) will be performed.
- by controlling to adjust temperature and vaporizer detector, (the 17 of Fig. 4,18,19) difference between temperature is optimizing solution
The persistent period in jelly cycle.By analyzing this difference, in that case it can be decided that stop the proper timing of the operation of defrosting.This allows to thaw
Cycle automatization, without any outside intervention of the 3rd people.
- make thawing cycle automatization and optimization, reduce in refrigerated storage compartment (due to related to any course of defrosting
Physical process and cause) the increased temperature of the temperature of commodity raises, and after thawing and terminating operation, needs less energy
Maintain SETPOINT.
Following paragraph statement completes the detailed description of the analysis model：
A, upon power-up (1 of Fig. 2) reset the data storage of electronic controller.Electronic controller performs and adjusts to reach
To business SETPOINT (SETPOINT used during any " normal mode "), then by using temperature change point

B, in the setting stage (the 2 of Fig. 2) for analyzing new PERIOD (period), and depend on preset configuration, Electronic Control
Device will start the new PERIOD analyses of scheduled period (from 1 to 20 days).Any PERIOD is divided into the son interval per 30 minutes simultaneously
And referred to as unit (CELLs).CELL is used for all temperature datas (figure collected, analyze and classify from usable temp detector
3)。
C, in the time intervals of any 30 minutes (be equal to a CELL) (Fig. 3), algorithm storage is higher than coefficient CDS (Fig. 3
Temperature change (VT) (the 14 of Fig. 3) 11,12,13) quantity.That CELL (CDC) at the end of any one CELL
Middle diffusion coefficient is updated (the 15 of Fig. 3).
D, once a day, or any 48 CELLs are once, by the average (MVT) of temperature change, as the nearest of VT
The meansigma methodss of 48 storage values.Then by CDS coefficient updates (the 8 of Fig. 2) be it is nearest 48 storage CDC values meansigma methodss.So
Appropriate VT numbers according to CELL afterwards, algorithm classification belong to the CELL of the PERIOD for just having completed：
If the VT numbers of-n-th CELL are greater than or equal to meansigma methodss MVT (the 11 of Fig. 2), then n-th CELL is classified
Belong to " normal mode " (NM-CELL).
If VT number subaverages MVT (the 11 of Fig. 2) of-n-th CELL, then n-th CELL is classified and belongs to " section
Energy pattern " is (ES-CELL).
The last operation of-algorithm is for equipment systematic function model (the 11 of Fig. 2), wherein belonging to the CELL quilts of same pattern
It is divided into one group.Filter is used for forcing any ES-CELL sequences less than preset value (which depends on configuring) to belong to " conventional mould
Formula ".
E, perform below step during any new PERIOD is analyzed：
- repeat to implement part above (B) here
- repeat to implement part above (C) here
If-by analysis, real CELL shows the pattern for belonging to different (relative to previous PERIOD), then this
The operational mode of individual CELL is changed (the 6,7 of Fig. 2) at once.
- repeat to implement part above (D) here.
Following paragraph provides the detailed description of management of thawing automatically：
