Title:
COOLING/HEATING SYSTEM
Document Type and Number:
Japanese Patent JP2016169894
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cheap cooling/heating system.SOLUTION: A cooling/heating system includes a heat source machine 1, a plurality of terminals 6 for cooling/heating and a terminal dedicated for heating 7 in which a water circulation circuit is connected to the heat source machine, and a main remote controller 23 connected with the heat source machine by a two-way communication wire and for giving a command to the heat source machine for operation, temperature setting and the like. The terminal dedicated for heating is a hot water heating machine 7 including a thermal valve 29 and a control unit 31 inside, and communication between the hot water heating machine and the heat source machine is performed by using a terminal control wire for transmitting the information from the hot water heating machine into one direction. In the case where the heat source machine is in a cooling operation, when a heating operation signal is transmitted to a control unit 13 of the heat source machine from the hot water heating machine, the heat source machine stops the cooling operation and displays an error by a heating signal input from the hot water heating machine on the main remote controller.SELECTED DRAWING: Figure 2
