Abstract

An indoor unit of an air-conditioning apparatus includes a housing, an indoor heat exchanger that is disposed in the housing and to which flammable refrigerant is supplied, and an indication section that indicates a minimum distance from a floor surface of the housing when installed on a wall of a room (installation height H0) along with an identifier on a lower surface of the housing.

Claims

1. A split type air-conditioning apparatus comprising an indoor unit and an outdoor unit, the indoor unit including a housing, an indoor heat exchanger being disposed in the housing and to which flammable refrigerant is supplied, and an indication section being provided on the housing and indicating an installation height for installation of the indoor unit in a room as stipulated in an international standard.

4. The air-conditioning apparatus of claim 1, wherein the indication section has embossing or debossing indication or printing indication.

5. The air-conditioning apparatus of claim 1, wherein the indication section is a member having embossing or debossing indication or printing indication that is permanently or removably attached.

6. The air-conditioning apparatus of claim 1, wherein the housing is configured to be installed on a wall, and the indication section is provided on a lower surface of the housing.

7. The air-conditioning apparatus of claim 1, wherein the housing is configured to be hung from a ceiling, and the indication section is provided in the housing at a position that faces an air inlet that is open to a lower surface of the housing.

8. The air-conditioning apparatus of claim 1 wherein the housing is configured to be embedded in a ceiling, and the indication section is provided on a lower surface of an electronics box.

9. The air-conditioning apparatus of claim 1, wherein the housing is configured to be installed on a wall via an installation board, and the indication section is provided on the installation board.

10. The air-conditioning apparatus of claim 1, wherein the refrigerant is R32 (CH₂F₂, difluoromethane), which is HFC refrigerant, HFO-1234yf (CF₃CF═

CH₂, tetrafluoropropene), or HFO-1234ze (CF₃—

CH═

CHF).

2. A split type air-conditioning apparatus comprising an indoor unit and an outdoor unit, the indoor unit including a housing, an indoor heat exchanger being disposed in the housing and to which flammable refrigerant is supplied, and an indication section being provided on the housing and indicating an available floor area in a room for the air-conditioning apparatus as stipulated in an international standard.

11. The air-conditioning apparatus of claim 2, wherein the indication section has embossing or debossing indication or printing indication.

12. The air-conditioning apparatus of claim 2, wherein the indication section is a member having embossing or debossing indication or printing indication that is permanently or removably attached.

13. The air-conditioning apparatus of claim 2, wherein the housing is configured to be installed on a wall, and the indication section is provided on a lower surface of the housing.

14. The air-conditioning apparatus of claim 2, wherein the housing is configured to be hung from a ceiling, and the indication section is provided in the housing at a position that faces an air inlet that is open to a lower surface of the housing.

15. The air-conditioning apparatus of claim 2, wherein the housing is configured to be embedded in a ceiling, and the indication section is provided on a lower surface of an electronics box.

16. The air-conditioning apparatus of claim 2, wherein the housing is configured to be installed on a wall via an installation board, and the indication section is provided on the installation board.

17. The air-conditioning apparatus of claim 2, wherein the refrigerant is R32 (CH₂F₂, difluoromethane), which is HFC refrigerant, HFO-1234yf (CF₃CF═

CH₂, tetrafluoropropene), or HFO-1234ze (CF₃—

CH═

CHF).

3. A split type air-conditioning apparatus comprising an indoor unit and an outdoor unit, the indoor unit including a housing, an indoor heat exchanger being disposed in the housing and to which flammable refrigerant is supplied, and an indication section being provided on the housing and indicating an installation height for installation of the indoor unit in a room and an available floor area in the room for the air-conditioning apparatus as stipulated in an international standard.
