Abstract
A control unit includes a mode control unit that, when a test operation switch is turned on, transmits information indicating that a test operation mode is performed to a centralized management device via an adapter and an external network. When the information indicating that the test operation mode is performed is received, the centralized management device restricts an operation on the operation terminal to prevent an operation of the air-conditioning apparatus from being changed via the operation terminal.
Claims16
An air-conditioning system comprising:
- an air-conditioning apparatus that includes an indoor unit and an outdoor unit;
- an adapter connected to the indoor unit, the adapter being configured to communicate with the indoor unit;
- and
- a centralized management device configured to communicate with an operation terminal to receive an operation information B from the operation terminal and further communicate with the adapter via an external network, wherein the operation information B indicates a requested change in operation of the air-conditioning apparatus which is output from the operation terminal,
- the indoor unit including
- a test operation switch configured to initiate a test operation mode in which a preset operation is executed, and
- a control unit connected to the adapter, the control unit being configured to perform the test operation mode when the test operation switch is activated,
- the adapter holds an adapter information A received from the air-conditioning apparatus, wherein the adapter information A indicates an operation status of the air-conditioning apparatus;
- wherein the adapter is configured to repeatedly output the adapter information A held in itself to the centralized management device via the external network;
- the control unit including
- a mode control unit configured to, when the test operation switch is activated, cause the adapter to transmit the adapter information A to the centralized management device via the adapter and the external network,
- wherein the centralized management device is configured to, while the adapter information A indicates that the test operation switch is activated, in response to receiving a request B from the operation terminal, wherein the request B requests information about a current operation of the air-conditioning apparatus, transmit an instruction A to the operation terminal, wherein the instruction A causes the operation terminal to prohibit an operation of the air-conditioning apparatus from being changed via the operation terminal;
- wherein the centralized management device is further configured to, while the adapter information A indicates that the test operation switch is activated, restrict a transmission of the operation information B to the adapter;
- wherein the centralized management device is further configured to, while the adapter information A indicates that the test operation switch is not activated, transmit the operation information B to the adapter and hold the operation information B in the centralized management device,
- wherein the control unit is further configured to:
- (i) while the test operation mode is activated, permit on-location components of the air-conditioning apparatus to operate according to the preset operation, and (ii) in a situation that the test operation mode is not activated when the adapter information A is received by the centralized management device at a first timing, the operation information B is output from the centralized management device to the control unit at a second timing that is later than the first timing, and the test operation mode is activated in an interval between the first timing and the second timing, operate the air-conditioning apparatus in the test operation mode regardless of the operation information B.
