Abstract: A frequency characteristics measurer is disposed in the vicinity of an end of refrigerant piping, the end of which is connected to an outdoor unit, that connects the outdoor unit and an indoor unit of an air conditioner, and measures frequency characteristics of the refrigerant piping. A filter is attached at a position between the outdoor unit and a position where a terminal of the frequency characteristics measurer is connected, so as to wrap the refrigerant piping. A piping length calculator is connected to the frequency characteristics measurer via an interface cable, and acquires, via the interface cable, frequency characteristics measured by means of the frequency characteristics measurer. The piping length calculator extracts a lowest anti-resonant frequency from the acquired frequency characteristics, and calculates the length of the refrigerant piping on the basis of the extracted lowest anti-resonant frequency.

Abstract: Probes of a conductor length measurement device are connected to piping, and an output voltage is applied to the piping through the probes. A frequency spectrum curve is subsequently calculated by subjecting a voltage signal to FFT. Resonant frequencies of the piping are then determined from this frequency spectrum curve, and the total length of the piping is calculated on the basis of the resonant frequencies. The total length of the piping can therefore be easily measured without the need to install, for example, any measurement instruments at branch terminals.

Abstract: A sampler samples a receive signal received via a dedicated communication line. A data transfer rate adjuster measures a data transfer rate based on a number of start bit samples contained in the receive signal. A bit determiner makes a bit determination regarding the receive signal at the data transfer rate measured by the data transfer rate adjuster, to thereby acquire serial data contained in the receive signal. A transmitter sends, via the dedicated communication line, a transmit signal containing serial data sent by an MPU. An MPU communicator outputs to the transmitter the serial data sent by the MPU, and outputs to the MPU the serial data acquired by the bit determiner. The data transfer rate adjuster adjusts, when the transmitter sends the transmit signal multiple times at different data transfer rates, the data transfer rate based on the receive status of respective response signals thereto.

A demodulator demodulates a voltage signal based on the potential difference between the communication wire and the shared wire, and outputs the signal as a demodulated signal.
