Abstract: An air conditioning apparatus includes a refrigerant circuit including a plurality of heat exchangers (a condenser and an evaporator), and an axial fan configured to send air to the heat exchangers. The refrigerant circuit and the axial fan are accommodated in a case. The heat exchangers are disposed in a direction orthogonal to an air flow direction, and the axial fan is disposed on one side of an arrangement direction of the heat exchangers, and supplies the air to the heat exchangers.

Abstract: A multiplex transmission system includes a multiplex transmission network through which normality and abnormality processing control specification information (PCSI) for loads are transmitted. A master load control unit (LCU) is connected to the multiplex transmission network. The master load control unit can multiplex the abnormality PCSi for a load as a main operation. A slave load control unit (LCU) is connected to the multiplex transmission network. The slave load control unit can multiplex the abnormality PCSI as a slave operation between itself and the main LCU. A storage device is mounted in the master and slave LCUs. The storage device can update and hold the information and read it at any time. In this multiplex transmission system, multiplexing abnormality can be detected and abnormality processing in the LCU in an abnormal state is controlled to urge its recovery of the LCU to a normal state.
