Fig. 1 shows the flow chart of the method for the internal temperature for controlling refrigerating equipment according to one embodiment of the present invention.
As shown in the figure, in step S101, detect the whether decent zero crossing of alternating voltage of refrigerating equipment.Such as can voltage between direct-detection live wire and zero line or the voltage that detects between the live wire and zero line of transformer pressure-reducing.
In step s 102, when the decent zero crossing of alternating voltage, judge whether to there is at least one control signal produced, this at least one control signal is for controlling at least one thermostat unit, and this at least one thermostat unit is compressor in described refrigerating equipment and/or low temp compensating heater strip.
In step 103, when there is at least one control signal produced, export at least one control signal described at least one thermostat unit.
By the method shown in Fig. 1, only when the alternating voltage zero passage of powering for refrigerating equipment, just and then judge whether will export control signal with control temperature regulon, thus the impact of reduction to electrical network.
Before step S101 in FIG, this at least one control signal can be produced in several ways.Exemplarily enumerate three kinds of modes below.
According in one embodiment of the present invention, the temperature of the refrigeration evaporator in refrigerating equipment and the environment temperature of refrigerating equipment can be obtained, and produce at least one control signal according to the temperature of refrigeration evaporator and environment temperature.Such as, the threshold value corresponding to this environment temperature in the multiple refrigeration evaporator temperature thresholds preset can be determined according to current environment temperature, again the temperature of this threshold value with the refrigeration evaporator obtained is compared, to determine whether to need start or close down compressor, and the need of access or disconnection low temp compensating heater strip.
According in another embodiment of the invention, the temperature of the refrigeration evaporator in refrigerating equipment, the environment temperature of refrigerating equipment and refrigerated space temperature can be obtained, and produce at least one control signal according to the temperature of this refrigeration evaporator, environment temperature and refrigerated space temperature.At this such as, the refrigerated space temperature of current environment temperature can be considered, to determine the threshold value corresponding to this environment temperature in the multiple refrigeration evaporator temperature thresholds preset.
According in another embodiment of the invention, the temperature of the refrigeration evaporator in the temperature controller gear and refrigerating equipment arranged by user can be obtained, and produce at least one control signal according to the temperature of temperature controller gear and refrigeration evaporator.At this such as, can directly determine according to temperature controller gear the threshold value corresponding to this environment temperature in the multiple refrigeration evaporator temperature thresholds preset.
One according to the present invention preferred embodiment in, user can arrange temperature controller gear by panel or control handle.But, it will be appreciated by those skilled in the art that can also in other manners, such as remote controllers control temperature controller gear.
One according to the present invention preferred embodiment in, at least one control signal is for starting or stop the signal of compressor and/or the signal for connecting or disconnecting low temp compensating heater strip.Such as, but this control signal can also be other the signal for control temperature regulon, controls the signal of compressor rotary speed.
Fig. 2 shows the schematic diagram of the device of the internal temperature for controlling refrigerating equipment according to one embodiment of the present invention.At this, illustrate only the exemplary device being carried out control temperature regulon by the temperature of refrigeration evaporator, the environment temperature of refrigerating equipment and the refrigerated space temperature obtained in refrigerating equipment, but the present invention is not restricted to this.
As shown in Figure 2, the device 200 for controlling the internal temperature of refrigerating equipment comprises the second sensor input module 201, second control module 205, zero passage detection module 206, judge module 207 and output module 208.
Second sensor input module 201 can comprise further again refrigeration evaporator temperature sensor 202, environment temperature sensor 203 and refrigerated space temperature sensor 204, second sensor input module 201 obtain corresponding temperature value according to those temperature sensors and sent to the second control module 205.
Second control module 205 produces at least one control signal according to received multiple temperature values, and this at least one control signal is continued to send judge module 207 to.
Zero passage detection module 206 detects alternating voltage, and produces such as pulse signal when alternating voltage zero passage, and sends this pulse signal to judge module 207.
When judge module 207 obtains pulse signal, it can judge whether to there is the control signal produced then, and this control signal is continued to send output module 208 to when there is control signal.
Output module 208 exports this control signal to compressor 209 and/or low temp compensating heater strip 210.With the break-make of the start and stop and/or low temp compensating heater strip 210 that control compressor 209.
Fig. 3 shows the circuit diagram of the zero passage detection module according to one embodiment of the present invention.But, the present invention can adopt in known zero cross detection circuit any one, and be not restricted to this.
As shown in the figure, during alternating voltage zero passage between live wire (L) and zero line (N), triode P2 conducting, therefore exports a positive pulse.Because mains frequency is 50Hz, therefore this circuit can produce the positive pulse signal of 50Hz, and by sending this signal to judge module, only to start or to close down thermostat unit when alternating voltage zero passage.
Although the foregoing describe the specific embodiment of the present invention, those skilled in the art can make various changes and modifications within the scope of the appended claims.
