Performance testing system and method for air conditioner

Abstract

A system for conducting performance tests of an air conditioner by operation modes, the system includes a test loader for loading an air conditioner to be tested; and a control unit for switching an operation mode of the air conditioner loaded on the test loader in order of cooling and heating operation modes at a preset lowest operating frequency and cooling and heating operation modes at a preset rated operating frequency, and executing the switched operation mode. Further, the system for conducting performance tests of an air conditioner by operation modes includes a checking unit for checking the existence of a malfunction in preset performances whenever each of the operation modes is executed; and a warning unit for visually and acoustically warning the check result on the existence of a malfunction in each of the operation modes.

1 . A system for conducting performance tests of an air conditioner by operation modes, the system comprising:
 a test loader for loading an air conditioner to be tested;   a control unit for switching the operation modes in order of cooling and heating operation modes at a lowest operating frequency and cooling and heating operation modes at a rated operating frequency to execute the switched operation modes;   a checking unit for checking the existence of a malfunction in preset performances whenever each of the operation modes is executed; and   a warning unit for warning the check result on the existence of a malfunction in each of the operation modes.   
   
   
       2 . The system of  claim 1 , further comprising:
 a display unit for displaying, on a monitor, the check results as final performance test results.   
   
   
       3 . The system of  claim 1 , wherein the warning unit includes:
 an LED for visually displaying the check result on the existence of a malfunction in each of the operation modes; and   a speaker for acoustically warning the check result on the existence of a malfunction in each of the operation modes.   
   
   
       4 . The system of any one of  claims 1  to  3 , wherein the preset performances include at least one of vibration level, noise level, existence of compression defects, switching state of a four-way valve, and normal operational states of sensors. 
   
   
       5 . A method for conducting performance tests of an air conditioner by operation modes, the method comprising the steps of:
 loading the air conditioner to be tested on a test loader;   operating the air conditioner in a cooling operation mode at a preset lowest operating frequency;   performing a first check on the existence of a malfunction in preset performances during the cooling operation for a specified period time;   switching the air conditioner to a heating operation mode after the first check is executed for a specified period of time;   operating the air conditioner in the heating operating mode at the preset lowest operating frequency to conduct a second check on the existence of a malfunction in preset performances;   switching the air conditioner to a cooling operation mode after the second check is executed for a specified amount of time, and operating the air conditioner at a preset rated operating frequency;   carrying out a third check on the existence of a malfunction in preset performances during the cooling operation at the preset rated operating frequency;   switching the air conditioner to a heating operation mode after the third check is executed for a specified period of time;   operating the air conditioner at the preset rated operating frequency to conduct a fourth check on the existence of a malfunction in preset performances; and   giving warnings every time the occurrence of a malfunction is detected during the first through the fourth tests.   
   
   
       6 . The method of  claim 5 , further comprising the step of:
 accumulating check results from the first through the fourth checks; and   displaying, on a monitor, the accumulated check results as final performance test results.   
   
   
       7 . The method of  claim 6 , wherein the include blinking LED light and outputting intermittent speaker sounds. 
   
   
       8 . The method of any one of  claims 5  to  7 , further comprising the step of:
 giving visual and acoustic warnings when the performance tests on the air conditioner are completed.   
   
   
       9 . The method of any one of  claims 5  to  7 , wherein the preset performances include at least one of vibration level, noise level, existence of compression defects, switching state of a four-way valve, and normal operational states of sensors.
