Abstract

Official abstract text for this publication.

An outdoor unit of an air-conditioning apparatus, wherein the outdoor unit has a control box and an electrical box accommodated therein, in the control box, devices serving as a controller configured to control refrigeration cycle-related devices are accommodated, and in the electrical box, devices including a thermal relay are accommodated, the devices producing a smaller amount of heat compared to the devices accommodated in the control box, the electrical box being formed separately from the control box.

First claim

Opening claim text (preview).

The invention claimed is: 1 . An outdoor unit of an air-conditioning apparatus, wherein the outdoor unit has a control box and an electrical box accommodated therein, in the control box, devices serving as a controller configured to control refrigeration cycle-related devices are accommodated, and in the electrical box, devices including a thermal relay are accommodated, the devices producing a smaller amount of heat compared to the devices accommodated in the control box, the electrical box being formed separately from the control box. 2 . The outdoor unit of an air-conditioning apparatus of claim 1 , wherein the electrical box is installed between a compressor and a fan, the compressor and the fan being included in the refrigeration cycle-related devices. 3 . The outdoor unit of an air-conditioning apparatus of claim 1 , wherein a heat medium pipe through which a heat medium circulates is accommodated in the outdoor unit, and the electrical box is installed in a vicinity of the heat medium pipe. 4 . The outdoor unit of an air-conditioning apparatus of claim 1 , wherein the thermal relay is a thermal burnout relay. 5 . The outdoor unit of an air-conditioning apparatus of claim 1 , wherein electric wires for the devices accommodated in the electrical box are connected from a lower side of the electrical box. 6 . The outdoor unit of an air-conditioning apparatus of claim 5 , wherein the electric wires include a first electric wire that is a power wire, and a second electric wire that is other than the power wire, and the electrical box includes a first wire connection port that is a connection port for the first electric wire, and a second wire connection port that is a connection port for the second electric wire. 7 . The outdoor unit of an air-conditioning apparatus of claim 1 , wherein all of the devices in the electrical box produce a smaller amount of heat compared to the devices accommodated in the control box. 8 . The outdoor unit of an air-conditioning apparatus of claim 7 , wherein each of the devices in the electrical box produce a smaller amount of heat compared to each of the devices accommodated in the control box. 9 . The outdoor unit of an air-conditioning apparatus of claim 1 , wherein the electrical box is installed at a height equal to or greater than a set height from an installation surface at which a bottom panel of a housing of the outdoor unit is installed. 10 . The outdoor unit of an air-conditioning apparatus of claim 9 , wherein the set height is nonzero. 11 . The outdoor unit of an air-conditioning apparatus of claim 9 , wherein the set height is 50 mm.
