PERFORMANCE TESTING DEVICE OF A REFRIGERATOR

摘要

The performance test device of a refrigerator includes: a control and testing part(10) for supplying a driving power to a tested refrigerator(28) and controlling the whole operation for the performance test thereto; an integrating wattmeter for transmitting an integrated watt value of the tested refrigerator(28) to the control and testing part(10) via a general purpose interface bus(12); a programmable logic controller(22) for controlling the operation of a door opening/closing part(26) which opens/closes a door of the tested refrigerator(28) on the basis of a control signal through a serial transmission interface(14) of the control and testing part(10); a temperature sensor(24) for digital-converting the internal temperature value of the tested refrigerator(28) via an analog/digital converter board(16) to thereby transmit the converted value to the control and testing part(10); and a software timer(18) for determining the operation time point of each of the integrating wattmeter(20), the programmable logic controller(22), and the temperature sensor(24).
