FIG. 1 is a flowchart showing a control method of a cooling rate controller according to an embodiment of the present invention. FIG. 2 is a logic diagram showing a cooling rate of operation according to an embodiment of the present invention. FIG. 4 is a logic diagram illustrating an alarm according to an operation rate of a compressor according to an exemplary embodiment of the present invention. Referring to FIG.

As shown in Figs. 1 to 4, the control method of the cooling rate controller of the present invention is a control method of the controller that calculates and displays the cooling rate of operation of the refrigerating and freezing equipment. First, the cooling operation of the refrigerating and freezing equipment is started S100). At this time, the cooling operation operation means the time when the cooling operation is restarted after the refrigeration refrigeration equipment is powered on or the defrosting operation is terminated.

Then, the cooling / refrigerating apparatus is operated to select either the cooling operation or the defrost operation according to the cooling setting condition during the cooling operation (S200). Here, the cooling setting condition refers to a condition such as a defrosting operation condition when the refrigerator is supercooled to a predetermined cooling temperature or higher and a condensation or the like occurs in the refrigerating and cooling equipment.

Then, in the defrosting operation, the defrosting operation is performed, and then the electronic side operation time and the entire elapsed time of the cooling operation are reset (S700) and the cooling operation is started again.

In the defrosting operation, as shown in FIG. 3, in order to prevent unnecessary defrosting, the present cooling operation rate is compared with the previous cooling operation rate, and when the present temperature is measured, the defrosting time To prevent unnecessary defrosting. At this time, the set temperature range means set temperature + deviation within 1.5 range.

That is, when the defrost cycle time during which the defrosting operation is to be performed is determined to be non-defective, the defrosting operation is not performed within the set maximum time within the set maximum time period and the defrosting operation is not performed It means the maximum time that unwanted defenses will not enter.

In addition, the criterion determining that there is no malfunction means that the temperature maintenance during cooling is considered to be safe in consideration of the previous cooling operation rate, the current cooling operation rate, and the maintenance state of the current temperature range, as shown in FIG. The comparison of the maximum cooling utilization rate of FIG. 3 shows that if the current cooling utilization rate is maintained at a high level, the risk of cumulative accumulation is increased irrespective of the comparison with the previous cooling utilization rate and the maintenance of the current temperature range. So that the defrosting period is set.

Then, the operating time (SOn Time) of the electromagnetic valve during the cooling operation is measured (S300), and the time of the electromagnetic valve ON (the time the electromagnetic valve is operated) and the time of the electromagnetic valve OFF Check and measure.

after that. The total elapsed time (T Time) of the cooling operation during the cooling operation is cumulatively checked and measured (S400).

The current operating rate is calculated by applying the measured electronic side operating time (SOn Time) and the total elapsed time of the cooling operation (T Time) to the following expression 1, and the calculated present operating rate is displayed on a display or the like S500).

[Formula 1]

(SOn Time / T Time) * 100 [%]

Here, SOn Time is the elapsed time of the electromagnetic valve, T Time is the total elapsed time of the cooling operation, and 100 is the percentage (%).

Then, the calculated current operating rate is input as a previous operating rate of the cooling (S600), that is, the operating rate inputted in this case is the data that is compared with the measured current operating rate .

Here, by comparing the inputted cooling operation rate (which is referred to as the previous cooling operation rate) with the newly calculated current cooling operation rate and generating alarms according to numerical values, It can be convenient.

After the current cooling operation rate is input as the previous cooling operation rate, the electronic side operation time and the entire cooling operation time are reset (S700).

Finally, after the resetting, the cooling operation is restarted from the beginning or the refrigeration cooling apparatus is terminated as it is.

In other words, according to the present invention, there is a controller in refrigerating and freezing equipment, and the controller calculates the time at which the cooling starts, the time at which the cooling starts, and the time at which the temperature reaches the set value, And expressed as a percentage, and the percentage is expressed as a cooling operation rate.

4, when the operation rate of the compressor is compared with the current operation rate of the compressor and the operation rate of the compressor is equal to or larger than the error rate of the current operation rate, And notifies the user.

In general, when the electromagnetic valve is operated, the compressor is also operated. When the electromagnetic valve stops, the compressor is also stopped. However, when there is a problem in operation of the compressor as shown in FIG. 4, the present invention considers that the difference between the operation time of the electromagnetic valve and the operation time of the compressor And automatically generates an alarm.

For example, if the compressor operation time is shorter than the electronic operation time, there may be a problem that the compressor operation setting is wrong or the compressor refrigerant is insufficient. On the other hand, if the compressor operation time is larger than the electronic operation time, It is possible to grasp the problem such as whether it is erroneous or is continuously open due to malfunction of the electronic valve.
