  • Patent number: 7765812
    Abstract: A system for detecting a mis-connected state between communication lines for a multi-type air conditioner and a method thereof. The system comprises an indoor unit pipe temperature detection unit for detecting a temperature of an indoor unit pipe, and a microprocessor for controlling an opening of an electronic expansion valve based on a temperature detected by the indoor unit pipe temperature detection unit, comparing a temperature response characteristic of the indoor unit pipe with a preset temperature response characteristic of a normal indoor unit pipe based on an opening of the electronic expansion valve, and thereby judging whether the communication lines are mis-connected to one another or not. An indoor unit from which the mis-connection has been generated is fast detected, and error information is displayed. Accordingly, the mis-connected state between the communication lines is restored, thereby preventing a damage of the system due to the mis-connection.

  • Patent number: 7735328
    Abstract: An apparatus and method for monitoring state information in a trial run mode of a multi-airconditioning system in which a plurality of indoor units are controlled by only one outdoor unit is disclosed. The apparatus and method connects a dedicated controller to the outdoor unit in a trial run mode of the multi-airconditioning system, such that it controls the indoor units and monitors state information of the indoor and outdoor units. The apparatus includes a trial-run-mode controller and a control input & state display unit. The trial-run-mode controller connected to the outdoor unit includes a trial-run-mode program for automatically detecting poor installation of the multi-airconditioning system.
