Abstract

PURPOSE:To considerably save labor and time, and use existing transmission lines to reduce the cost by transmitting voice information through control information transmission lines between an outdoor unit and indoor units. CONSTITUTION:An outdoor unit 1 has a controller 3, and indoor units 2 each have controllers 4 so that the indoor units 3 are controlled and operated independently. Mutual exchange of control information is required for integrated control and operation of two or more indoor units 2a-2f with the outdoor unit 1 as the core, and at least two transmission lines 5 are provided. The voice information that is input through a microphone 9 is modulated by a transmission modulator 10, passes through a filter 11, mixed by a mixing-separating circuit 8 with control information transmitted from a transmission circuit 6, and transmitted to the outdoor unit and indoor units through the transmission lines 5. On the other hand, incoming signals from the outdoor unit and the indoor units through the transmission lines 5 are separated into control information and voice information by the mixing-separating circuit 8, and only the voice information is modulated by a receiving modulator 13 after passing through the filter 14 and output from a microphone 12 as voice.

As shown in 1988-7, a plurality of indoor units are connected to an outdoor unit through refrigerant piping, so that each room can be heated and cooled individually. In this way, in order to integrate the distributed indoor units and operate them with the outdoor unit, a transmission line is provided between the outdoor unit and the indoor unit, and control information is exchanged through this line. Therefore, it has a transmission circuit for this signal and two signal lines.

Recent multi-air conditioning systems are becoming increasingly large-scale, with an indoor unit connected to an outdoor unit. At this time, the indoor units are distributed over several tens of meters in the horizontal direction and the height direction, and their operation is controlled individually. For this reason, trial runs and adjustments after installation currently require a large amount of manpower and time. On the other hand, if it becomes possible to mutually exchange information between indoor and outdoor units, it can be expected to save a considerable amount of manpower and time. Therefore, one method is to input information using a keyboard input device and display the information using a liquid crystal display device. However, this method may not be able to efficiently exchange a large amount of information, and there is also concern that the price of the device itself will increase.
