A panel assembly for a heating, ventilation, and/or air conditioning (HVAC) system includes a base panel having a sheet and a flange formed around a perimeter of the sheet, where the flange includes a plurality of openings, a stiffener bracket configured to couple to the flange and reinforce the base panel, and a liner panel configured to couple to the flange and reinforce the base panel, where the plurality of openings is configured to interchangeably couple to the stiffener bracket and the liner panel.

An indoor unit for an air-conditioning apparatus includes a casing forming an outer frame. The casing includes a lower right-side panel, a right bottom panel, a lower left-side panel, and a left bottom panel. The lower right-side panel, the right bottom panel, the lower left-side panel, and the left bottom panel each include a panel provided with a void through which pipes are drawn out and a panel without the void. The lower right-side panel, the right bottom panel, the lower left-side panel, and the left bottom panel with or without the void are selectively attached to the indoor unit.

An air-conditioning light-emitting system includes: air conditioners; light emitters; a first communication means that connects the air conditioners and that causes the air conditioners to communicate with each other; a plurality of second communication means that each connects one of the air conditioners to one of the light emitters and that causes the one of the air conditioners to communicate with the one of the light emitters; and a controller that controls the light emitters by using the first communication means and the second communication means.

The air fan with ice compartment is a thermal transfer device. The air fan with ice compartment is an enclosed structure that forces an air flow over a thermally treated mass, such as ice pack, and discharges the processed air flow into the atmosphere. The air fan with ice compartment comprises a base, a fan assembly, a fan control, an over chamber, and a lid. The fan assembly mounts on the base. The over chamber mounts over the fan assembly and the base. The lid and the fan control mount on the over chamber. The fan control controls the operation of the fan assembly. The fan assembly forces the air flow through the space enclosed by the over chamber and the base.
