摘要:
A communication apparatus is provided which is capable of easily detecting an error that is difficult to detect, in a communication cable. The communication apparatus performs communication using a communication cable including plural sets of paired wires each of which has two core wires, and includes: an interface unit (310) connectable to the communication cable; a measuring unit (320) which obtains measurement values by measuring a value indicating a state of each set of the paired wires included in the communication cable connected to the interface unit (310); and an error information output unit (330) which outputs error information indicating an error in the communication cable when the measured values obtained by the measuring unit (320) are substantially different.

摘要:
An air conditioning system comprising a refrigerant circuit. A thermal storage device is arranged in the refrigerant circuit and can store heat and utilize the stored heat to increase heating capacity at the time of kickoff of heating. A temperature detector detects a temperature at a thermal storage portion of a thermal storage and radiating heat exchanger which is housed in the thermal storage device. A counter counts a thermal storage operation period required for the temperature detected at the thermal storage portion to achieve a predetermined value, outputs a signal indicative of stopping a thermal storage operation when the detected temperature has achieved the predetermined value, counts the lapse of a predetermined thermal storage operation stoppage period after stop of the thermal storage operation, and outputs a signal indicative of starting the thermal storage operation when a predetermined thermal storage operation stoppage time has passed. A controller controls comparing the counted thermal storage operation period with a present value, and determines the next thermal storage operation stoppage period, depending on the length of the counted thermal storage operation period.
