Temperature control device for refrigerating apparatus and method thereof

A temperature control device of a refrigerating apparatus comprising:

• a temperature detecting unit installed in a chilling chamber of a refrigerating apparatus for outputting a temperature detecting signal when temperature in the chilling chamber exceeds a predetermined temperature;
• a heat generating lamp mounted in the chilling chamber of the refrigerating apparatus for emitting heat according to a control signal;
• and
• a microcomputer for controlling a driving of a compressor installed in the refrigerating apparatus on the basis of the temperature detecting signal of the temperature detecting unit or for calculating an operation rate of the compressor and outputting the control signal on the basis of the calculated compressor operation rate, thereby controlling the driving of the compressor.

A temperature control device of a refrigerating apparatus comprising:

• a temperature setting unit for setting temperature of a chilling chamber and a freezing chamber according to a user's demand;
• a temperature detecting unit installed in the chilling chamber of the refrigerating apparatus for outputting a temperature detecting signal when temperature of the chilling chamber exceeds a predetermined temperature;
• a heat generating lamp mounted in the chilling chamber of the refrigerating apparatus for emitting heat according to a control signal;
• and
• a microcomputer for controlling a driving of the compressor installed in the refrigerating apparatus on the basis of the temperature detecting signal of the temperature detecting unit or for calculating an operation rate of the compressor and outputting the control signal on the basis of the calculated compressor operation rate, thereby controlling the driving of the compressor, wherein the operation rate of the compressor is determined by a rate of the temperature detecting signal outputted from the temperature detecting unit.

A method for controlling temperature of a freezing chamber and a chilling chamber of refrigerating apparatus having a compressor and a heat generating lamp, the method comprising the steps of:

• calculating an operation rate of the compressor installed in the refrigerating apparatus;
• determining whether the calculated operation rate of the compressor is less than a predetermined operation rate or not;
• determining that peripheral temperature of the refrigerating apparatus is low and operating the compressor, when the calculated operation rate of the compressor is less than the predetermined operation rate;
• and
• operating the compressor by a temperature detecting signal of a temperature detecting unit installed in the chilling chamber and stopping an operation of the heat generating lamp when the calculated operation rate of the compressor is more than the predetermined operation rate, wherein the operation rate of the compressor is determined on the basis of a rate of the temperature detecting signal of the temperature detecting unit installed in the chilling chamber of the refrigerating apparatus.
