ABSTRACT:
A multi-inverter air conditioner includes an outdoor heat exchanger having a refrigeration cycle, and a plurality of indoor heat exchangers connected to the outdoor heat exchanger by pipes and wire arrangements. Each indoor heat exchanger includes a control part for detecting a temperature of the respective pipe arrangement. Each pipe arrangement includes a pipe controller for opening the pipe. The outdoor heat exchanger comprises a control section for actuating the various pipe controllers and control parts for performing a test of the system. The outdoor heat exchanger further includes an input section for enabling a user to input a command signal to initiate the testing procedure, and a display section for displaying results of the test. During a test procedure, the temperatures of all pipe arrangements are detected before and after the refrigeration cycle has been actuated. If no temperature variation is detected in any of the pipe arrangements, the test procedure is terminated and a malfunction signal is displayed.
