Abstract
The utility model discloses an energy-saving controller for an inverter compressor. The energy-saving controller comprises an MCU (microprogrammed control unit) control module, a temperature sensor and an inverter compressor control module, wherein the temperature sensor is connected with the MCU control module; the energy-saving controller also comprises a timing module; the timing module is connected with the MCU control module, and is used for calculating the single cumulative working time of the inverter compressor; when the single cumulative working time of the inverter compressor is higher than a set value, a frequency adjustment signal is output by the MCU control module to the inverter compressor control module. As the basic working frequency of a compressor is set by the freezer controller disclosed by the utility model, the freezer controller is suitable for the daily temperature control requirement that the weather is cool or the storage capacity of foods in a freezer is comparatively stable; under the condition that a freezer compressor works at low frequency for a longer time due to the factors that doors are opened frequently or summer temperature is higher, i.e. under the condition the freezer cannot be stopped for a long time, the working frequency of the compressor is adjusted according to the temperature in the freezer, and therefore the energy-saving effect of the inverter compressor is exerted to the maximum degree.
Description
Technical field
The utility model relates to control system technical field, and more particularly, it relates to a kind of frequency-changeable compressor energy-saving controller of intelligent refrigerator.
Background technology
Society science and technology, economic development are rapid, and refrigerator has been the electric equipment of universal every family.Refrigerator makes food fresh-keeping and low tempertaure storage, conventionally requires for a long time, stably to provide the environment of a low temperature, and therefore, the power consumption of refrigerator is relatively large.Advocate energy-conserving and environment-protective are fundamental state policies of China, the research of energy-saving refrigerator be production firm must developing direction.At present, for the conservation measures of refrigerator, be mainly that the running parameter of each important composition parts is optimized in refrigerator, to reach energy-conservation effect, still, carrying out reasonable control efficiency for refrigerator inside part, to reduce the scheme of complete machine energy consumption little.
Utility model content
the purpose of this utility model isovercome the deficiencies in the prior art, a kind of frequency-changeable compressor energy-saving controller is provided, can be to the heart component of refrigerator---frequency-changeable compressor, unify optimal control in conjunction with freezer temperature control procedure parameter, under different conditions, carry out different FREQUENCY CONTROL schemes, to reach energy-conservation object.
The utility model is achieved through the following technical solutions: frequency-changeable compressor energy-saving controller, comprise MCU control module, connect temperature sensor, the frequency-changeable compressor control module of MCU control module, also comprise timing module, described timing module connects MCU control module, adds up the working time for the single that calculates frequency-changeable compressor, when single accumulative total working time of frequency-changeable compressor is during higher than setting value, described MCU control module output frequency is adjusted signal to frequency-changeable compressor control module.
Preferably, described timing module automatic clear in the time that frequency-changeable compressor is shut down.
Preferably, described MCU control module is also connected with refrigerator doors closed condition detection module.
Preferably, described MCU control module is also connected with refrigerating chamber lighting lamp control module, and described refrigerating chamber lighting lamp control module is connected with refrigerating chamber illuminating lamp.
The beneficial effects of the utility model are: refrigerator controller is set the groundwork frequency of a compressor; be applicable to the day normal temperature control that weather is nice and cool or refrigerator food storage capacity is comparatively stable required; when the quantity of food just having put in is large or it is frequent to open the door or the more high factor of summer temperature makes freezer compressor longer with the working time of low frequency operation; in situation about can not shut down for a long time; adjust the operating frequency of compressor according to the temperature inside the box, thereby bring into play to the full extent the energy-saving effect of frequency-changeable compressor.
Brief description of the drawings
Fig. 1 is frequency-changeable compressor energy-saving controller theory diagram of the present utility model.
Fig. 2 is application refrigerator temperature power curve schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but structure of the present utility model is not limited only to following examples:
Referring to Fig. 1-2, the utility model frequency-changeable compressor energy-saving controller comprises MCU control module, connect temperature sensor, the frequency-changeable compressor control module of MCU control module, also comprise timing module, described timing module connects MCU control module, adds up the working time for the single that calculates frequency-changeable compressor, when single accumulative total working time of frequency-changeable compressor is during higher than setting value, described MCU control module output frequency is adjusted signal to frequency-changeable compressor control module.Timing module is automatic clear in the time that frequency-changeable compressor is shut down or while again startup, enters the refrigeration control of next round.And MCU control module can also connect refrigerator doors closed condition detection module, refrigerating chamber lighting lamp control module etc., wherein refrigerating chamber lighting lamp control module is connected with refrigerating chamber illuminating lamp, and in the time that refrigerator doors is opened, refrigerating chamber illuminating lamp is bright.And refrigerating chamber illuminating lamp also can be used as the heat input source of temperature of refrigerating chamber compensation.
The utility model is first controlled compressor with low frequency operation, in the time of compressor low frequency operation, its power is lower, in the time that the available machine time of compressor exceedes default single and starts the longest working time, while having reflected low-frequency operation, the refrigerating capacity of compressor can not meet the requirement of refrigerator, now, system is adjusted into the frequency of compressor higher frequency band operation again, reduces rapidly the temperature inside the box.Referring to Fig. 2, from the temperature curve 2 of refrigerator and the corresponding relation of power curve 1, can find out, in the time that refrigerator temperature is higher, refrigerator is with larger Power operation a period of time, until case temperature changes low-power stable operation into after reaching setting value, in the time that the accumulative total available machine time within a cycle of operation exceedes single and starts the longest working time and the temperature inside the box still fail to reach the temperature value of setting, system is transformed to high power operation, and case temperature is lowered rapidly.
