An assembly includes a first bracket and a second bracket. The first bracket includes a first member that includes a plurality of fingers and a first channel between the plurality of fingers. The first channel includes a plurality of teeth. A first flange extends from the first member and includes a first engagement surface. The second bracket includes a second member and a third member spaced from the second member. A second channel is formed between the second member and the third member. A second flange extends from the second member on an opposite side of the second member from the third member. The second flange includes a second engagement surface. In an installed configuration, the first bracket is secured to the second bracket; the first engagement surface faces the second engagement surface; and the plurality of fingers are inserted into the second channel.

An installation device configured to hold a window mounted split air-conditioner. The installation device comprises a support structure configured to be mounted on the window sill, and a mechanism for guiding the outdoor unit from a position inside the window opening to a position outside the window opening, and holding the outdoor unit in that position for use.

An air management device may include three independently operated primary impellers 131, 131′, 131″, and drawn-in air is discharged through discharge ports 15′-1, 15′-2, 15′-3 provided in the front plate 15 of the housing 10. Louvers 141, 142, 143installed downstream of the air flow and discharge ports 15′-1, 15′-2, 15′-3 may be independently opened or closed to provide discharge of the air to the surrounding environment. Further, at least one retractable or pop-up fan may be provided. A bottom inlet 11′ may be formed on the bottom plate 11 of the housing 10 facing the floor of the living space above a predetermined distance. The replaceable filter 300 may be installed to filter the air sucked through the bottom inlet 11′, and may be drawn in and out of the housing 10.

A mounting bracket includes a support frame extending in an inside-outside direction and including an outdoor part configured to be arranged outdoors, and a support leg configured to be arranged outdoors. An upper end of the support leg is connected to the outdoor part of the support frame and a lower end of the support leg is configured to directly or indirectly abut against an outer wall surface of a wall body. The outdoor part of the support frame includes a first limiting structure. The support leg includes a second limiting structure provided at the upper end of the support leg. The second limiting structure is in a limiting fit with the first limiting structure to limit a maximum included angle between the support leg and the support frame facing towards an indoor side so as to prevent a rotation angle of the support leg relative to the support frame in a direction facing away from the wall body from exceeding the maximum included angle.

An environmental control unit for providing heated or cooled air to an enclosed environment, such as a building structure or temporary shelter. Air passes through the environmental control unit and the air is heated or cooled by a temperature control system of the environmental control unit. The heated or cooled air is provided to the enclosed environment.

Embodiments of the present invention provide systems and methods for mounting an electrically-powered device to a ceiling or other supporting structure. The electrically-powered device can be, for example, a ceiling fan, a ceiling fan with a lighting fixture, or a lighting fixture.

A heating, ventilation, and air conditioning (HVAC) system includes one or more compressors, one or more outdoor heat exchangers, and one or more indoor heat exchangers. The HVAC system also includes a base pan on which the one or more compressors are mounted. The base pan includes a base level and one or more tier levels higher than the base level. The distance from any point on a perimeter of the first-tier level to a nearest point on a perimeter of the base level is based on the smallest bolt circle diameter of the one or more compressors mounted on the base pan. Also, the perimeter lengths of the tier levels are based on a percentage of the base level perimeter length.
