Abstract: PURPOSE: To perform the simultaneous operation of cooling and heating without providing a plurality of four-way switching valves and to reduce manufacturing costs by dividing an outdoor heat exchanger according to the number of indoor heat exchangers and at the same time connecting each liquid pipe to each second gas support pipe using a connection pipe, and including a switching valve at the second gas support pipe. CONSTITUTION: A liquid pipe 15 at the side of a room A and a second gas support pipe 22 at the side of a room B and then a liquid pipe 16 at the side of the room B and a second gas support pipe 21 at the side of the room A are connected by connection pipes 27 and 28, respectively. For example, a discharge gas refrigerant from a compressor 1 is supplied to the side of a first gas pipe 6. A refrigerant flowing through a flow-dividing path at the side of the room A is condensed by an outdoor heat exchanger 11, is evaporated by an indoor heat exchanger 23, and then is returned to the compressor 1. On the other hand, in the flow- dividing path at the side of the room B, the refrigerant does not cause condensation when passing the outdoor heat exchanger 12 where an outdoor fan is at halt, flows into the indoor heat exchanger 24 and is condensed.  The refrigerant is bypassed to the connection pipe 27 since an on-off valve 34 is in closed valve state, flows into the liquid pipe 15 at the side of the room A, passes the heat exchanger 23, and is returned to the compressor 1, thus achieving the simultaneous operation of cooling and heating.

Filed: 1994-10-17
Abstract: PURPOSE: To detect collision by each transmission station while suppressing the reduction of throughput by transmitting a signal representing the collision of data by judging the detection of a carrier on a transmission line in a prescribed period as the collision of the data. CONSTITUTION: A transmission control circuit 11 performs the dividing processing of transmission data so as to reduce probability to detect the collision of a data frame and to set colliding frame length at the same length when a line is set in an idling state. Thence, the circuit 11 releases a carrier switch signal by transmitting to a changeover switch 1c via an inverter 1h to exclude the sneak path of a transmission signal to a reception system, and after that, transmits the data frame via a modulation circuit 1i and a high-frequency transmission circuit 1e. After transmission, a collision detection circuit 1k detects the collision by a carrier sense window when it is detected, and reports a jam signal representing the occurrence of the collision to a station in which the collision occurs and from which the transmission signal is transmitted, and performs re-processing.
