JPH09152171A - Method for getting state information of indoor device in air conditioning system and air conditioning system - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate the connection of a relay panel or a contact point terminal by a method wherein an indoor device gets a state information of another indoor device in response to an information getting specifying signal, this information is fed out to an information input/output means connected to the indoor device and then the state information of the indoor device is attained through an information inputting means. SOLUTION: A control base plate 11 (#1) is arranged in an indoor device 10 (#1). This control base plate 11 (#1) performs various kinds of controlling operation. A state signal of each of the indoor devices [indoor devices 10(#1) to 10 (#3)] is taken under a state different from an operating signal obtained from an obtained state specifying switch SW 3. Then, the control base plate 11 (#1) of the first indoor device 10 (#1) sends out a state information of another indoor device 10 or self-state information of the indoor device 10 through the relay panel 20, a remote panel 30 gets a state information of the indoor device 10 through the relay panel 20. In this way, a mere connection of a single relay panel 20 to the indoor device 10 enables the state information of each of the indoor devices 10 to be attained.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system for automatically heating and cooling an indoor unit, and more particularly to setting automatic operation of this air conditioning system.

[0002]

2. Description of the Related Art Conventionally, this type of air conditioning system has one outdoor unit installed outdoors, and at least one unit connected to the outdoor unit and installed in a room to be controlled. Of the indoor unit and a remote controller as an operating means connected to any one of the indoor units by a cord or wirelessly, and the set temperature set by the remote controller and the indoor unit or the remote controller are provided. The temperature is compared with the detected temperature from the temperature sensor, and the cooling operation or the heating operation is performed according to the temperature difference.

In this air conditioning system, so-called group control is performed in which a plurality of indoor units are simultaneously operated by one remote controller. Further, in this group control, due to the convenience of the control, the convenience of construction, etc., the start / stop signal (O
By inputting (N / OFF signal) to one indoor unit, group control is executed and stopped (that is, individual operation).

The air conditioning system shown in FIG. 3 will be described below as an example. In the figure, the indoor unit 10 includes first (multi-address # 1) to ninth (same # 9) indoor units, and the indoor units 10 (# 1), 10 (# 4) and 10 (#
7), remote controllers 40 (# 1), 40 (#
4) and 40 (# 7) are attached.

Further, the indoor units 10 (# 1) to 10 (#
3) are connected in parallel by the data transfer line DTL (G1), thereby forming a first control group that is simultaneously controlled by the remote controller 40 (# 1).

Similarly, the indoor units 10 (# 4) to 10 (#
6), data transfer line DTL (G2) and remote controller 40
The second control group is configured by (# 4), the indoor units 10 (# 7) to 10 (# 9), and the data transfer line DTL.
(G3) and the remote controller 40 (# 7) form a third control group.

On the other hand, the indoor units 10 (# 1), 10 (# 4)
And relay relay boards 20 (# 1) and 2 (10) (# 7).
0 (# 4) and 20 (# 7) are connected.

These relay relay boards 20 (#
Remote board 3 via 1), 20 (# 4) and 20 (# 7)
The start / stop signals for controlling the execution and stop of the group control sent from 0 are transmitted to the indoor units 10 (# 1), 10 (#
4) and 10 (# 7), the control modes in the above-mentioned first control group, second control group and third control group, that is, execution of group control, individual operation for each indoor unit Is set.

[0009]

By the way, in such an air conditioning system, the manner in which the state signal indicating the operating state of the indoor unit 10 is taken out, that is, from which indoor unit 10 the state signal is acquired, is determined by the user. It depends on the degree of management on the side, and it is necessary to meet various demands.

Since this status signal is a signal unique to each indoor unit 10, when each indoor unit 10 is in the individual operation state, the relay relay board 20 is connected to each indoor unit 10 as shown by the dotted line in the figure. Connect these relay relay boards 20
It is necessary to acquire the status signal of the indoor unit 10 from each of the indoor units, and in the case of collectively controlling each control group, the contact terminals that output the status information are connected in parallel to all the indoor units belonging to the same control group. There was a need.
