Abstract: PURPOSE:To simplify wiring work by a method wherein a receiver of a signal of a radio remote control for a remote operation is connected with an air conditioner by a signal line. CONSTITUTION:Air-conditioned air sent from an air conditioner 3 is blown off from an air port 6 via an air passage 5, so as to air-condition a living room 1. In this construction, the air port 6 is fitted to a ceiling 14 and has a receiver 7 of a signal of a radio remote control 9 incorporated, and the signal receiver 7 and a control device 4 of the air conditioner 3 are connected together electrically by a signal line 8. This signal line 8 is not passed through a space, such as the rear of a wall surface or an underfloor space, in which wiring is difficult, but is laid through a space 11 in the ceiling. According to this constitution, wiring work can be conducted simply.

Abstract: PURPOSE:To enable a refreezing of brine after releasing a freezing operation to be prevented by a method wherein normally a temperature of brine at an outlet port of a cooling unit is kept at a predetermined target temperature so as to control a capacity of a freezer and when a flow passage resistance of brine in the cooling unit is increased to show an abnormal state so as to decrease a capacity of the freezer, the target temperature of the brine is increased to control the capacity. CONSTITUTION:Under a normal operation, a flow passage resistance is detected by a differential pressure transmitter 5, a brine temperature is outputted to a capacity controller device 2 by a micro-computer 3 in such a way as it is kept at a target temperature at an outlet port of a first cooling unit so as to control a capacity of a freezer. In case that the flow passage resistance is increased to show an abnormal state, the micro-computer 3 may output an abnormal state sensing signal to a capacity controlling device 2 so as to reduce the capacity of the freezer and at the same time the brine target temperature is set at the target temperature at the outlet of the second cooling unit so as to be increased and then it is outputted to the capacity control device 2 in such a way as to keep it at its target temperature and further during a defreezing operation, the capacity controlling operation in response to the load is carried out.
