摘要:
When a prior-art transmission scheme is to be applied to an airconditioning equipment already installed in a building or a house, refrigerant pipes serving as communication media and an in-room unit as well as an out-room unit need to be insulated, so that steel pipes near both the ends of each refrigerant pipe have been inevitably replaced with electrical insulation devices.(Means for Resolution)An airconditioning equipment having an in-room unit 2 connected to one end of refrigerant pipes 3, 4, and an out-room unit 1 connected to the other end of the refrigerant pipes 3, 4, is characterized by comprising signal coupling portions 7 which are respectively disposed at both the end parts of the refrigerant pipes 3, 4, each of which couples an AC control signal to the refrigerant pipes 3, 4, and each of which exhibits a predetermined impedance with respect to an AC electric signal.Owing to such a configuration, the present invention brings forth the advantages that the electrical insulation devices as in the prior art are dispensed with, and that the signal transmissions between the in-room unit 2 and the out-room unit 1 can be performed by the simple apparatus configuration.

A test device simulator simulates the behavior of a test device to be tested on the basis of content indicating an input operation by a user, data transmitted from an air-conditioning system simulator, and device object data stored in a data storage. In the case in which the simulation generates data to transmit to the air-conditioning system simulator, the test device simulator transmits that data to the air-conditioning system simulator. The air-conditioning system simulator includes multiple simulation process sections. Each simulation process section, on the basis of content indicated by the input operation performed by the user on the device simulated by the simulation process section itself, data addressed to that device transmitted from the test device simulator, and the device object data stored in the data storage and corresponding to that device, simulates the behavior of that device.

The present invention is to provide a system connection adapter and a terminal device, which allow a function which is newly developed and added by a maker on a system A to be handled on an open system B even in the case where the system A which is an existing system for supervising and controlling such as an air conditioning apparatus and a lighting apparatus installed in a building or at home is connected with the open system B which is made up by using a protocol different from that used by the system A. This allows for ease in expanding functions. According to the system connection adapter, a conventional command, which is the original of the system A, and therefore not specified in the open system B and has no correspondence available, is added with a frame header B by a frame encapsulation and decapsulation means, and transmitted in its original form. Then, the terminal device connected on the system B is provided with the function of extracting a command A 104 from a frame B transmitted, and interpreting the command A to be processed.
