Abstract

An air-conditioning apparatus, being able to download operation control information through a network, wherein a remote controller of the air-conditioner is structured, so that it can indicate the operation information download, and is provided a function of indicating an operation under the operation mode upon the basis of that operation information to the air-conditioner. And also, a function is provided for inhibiting transmission of the information between the network, thereby obtaining an improvement on operability after downloading, as well as, an improvement on operability during the download operation, and also protection from erroneous operation(s) caused due to being connected to the network.

Claims

1. An air-conditioning apparatus, having:

a compressor;

an outdoor heat exchanger;

an indoor heat exchanger;

an outdoor fan;

an indoor fan; and

a controller for controlling said compressor, said outdoor fan and said indoor fan, wherein, said controller comprises;

a transmission portion to be connected with a network for sending and receiving information;

a memory means for memorizing operation control information received through said transmission portion;

a remote controller transmission portion for transmitting information between a remote controller; and

means for operating the air-conditioner under an operation mode upon basis of said operation control information from a remote controller.

2. An air-conditioning apparatus, as defined in the claim 1, wherein said remote controller comprises a display portion for displaying the operation mode which is made operable by said operation control information.

3. An air-conditioning apparatus, as defined in the claim 1, further comprising means for informing a user of completion when receiving of said operation control information is completed.

4. An air-conditioning apparatus, having:

a compressor;

an outdoor heat exchanger;

an indoor heat exchanger;

an outdoor fan;

an indoor fan; and

a controller for controlling said compressor, said outdoor fan and said indoor fan, wherein, said controller comprises;

a transmission portion to be connected with a network for sending and receiving information;

a memory means for memorizing operation control information received through said transmission portion;

a remote controller transmission portion for transmitting information between a remote controller; and

a memory portion for memorizing a part of said operation control information in said remote controller.

5. An air-conditioning apparatus, as defined in the claim 4, wherein the part of said operation control information memorized in said remote controller contains at least data number and a content to be displayed on said remote controller corresponding to said data number.

6. An air-conditioning apparatus, having:

a compressor;

an outdoor heat exchanger;

an indoor heat exchanger;

an outdoor fan;

an indoor fan; and

a controller for controlling said compressor, said outdoor fan and said indoor fan, wherein, said controller comprises;

a transmission portion to be connected with a network for sending and receiving information;

a memory means for memorizing operation control information received through said transmission portion;

a remote controller transmission portion for transmitting information between a remote controller; and

a download means for taking said operation control information via said network into said memory portion through conduction on said remote controller.

7. An air-conditioning apparatus, as defined in the claim 6, wherein said download means provided in said remote controller has a means for inputting an operation mode for conducting the download, and a means for selecting a space for memorizing the information downloaded.

8. An air-conditioning apparatus, as defined in the claim 6, further comprising plural numbers of buttons, and means for displaying the operation mode contained in said operation control information downloaded corresponding to said buttons.

9. An air-conditioning apparatus, having:

a compressor;

an outdoor heat exchanger;

an indoor heat exchanger;

an outdoor fan;

an indoor fan; and

a controller for controlling said compressor, said outdoor fan and said indoor fan, wherein, said controller comprises;

a transmission portion to be connected with a network for sending and receiving information;

a memory means for memorizing operation control information received through said transmission portion;

a remote controller transmission portion for transmitting information between a remote controller; and

means for inhibiting transmission of information between said network.
