A method for installing a universal air handler for a building air conditioning system includes installing a compact outdoor cabinet having a blower and separate intake and outlet chambers separated by an evaporator core. Cool and return air ducts from the building couple to each chamber. Return air drawn by the blower into the return air chamber passes across the evaporator, then through the blower and out through the cool air duct. Coolant lines couple the evaporator to a nearby stand-alone condenser/compressor unit. In one embodiment, an adapter enables stacking the condenser/compressor unit atop the cabinet to reduce the footprint of the combination. In another embodiment, a manifold couples permanently to the building air ducts and releasably couples to the cabinet. The universal air handler easily decouples from the manifold for transportation and maintenance. The manifold may be installed in various locations around the building, including on the roof.

A universal air handler unit includes a blower and evaporator juxtaposed one another within a compact, weather resistant cabinet adapted for outdoor installation. Ports for cool and return air ducts disposed on one side of the cabinet couple directly to the blower and evaporator respectively. Return air drawn by the blower into the cabinet passes across the evaporator core, then through the blower and back out through the adjacent cool air duct. Coolant lines couple to a stand-alone condenser/compressor unit. In a particular embodiment, an adapter enables stacking the condenser/compressor unit atop the cabinet to reduce the overall footprint of the combination. In another embodiment, a manifold adapted to couple to the cool and return air ducts may be installed in various locations, the air handler unit slideably coupling to the manifold during installation, and easily decoupling and reecoupling for transportation and maintenance.

An inflatable product includes a top sheet and a bottom sheet at least partially defining an inflatable chamber. The inflatable product also includes a tensioning member which includes a first belt having a first top extension, a first bottom extension, and a first base extending between the first top extension and the first bottom extension. The tensioning member also includes a second belt having a second top extension, a second bottom extension, and a second base extending between the second top extension and the second bottom extension. The first top extension of the first belt and the second top extension of the second belt are attached to the top sheet, and the first bottom extension of the first belt and the second bottom extension of the second belt are attached to the bottom sheet. The first base and second base each have two side edges with arcuate-shaped recesses.

Disclosed is a container, such as an above-ground pool, with an improved porthole. The container can include a base, a side wall joined to the base, and at least one porthole. The porthole can comprise an aperture in the side wall and a generally transparent window sheet attached to the side wall and completely covering the aperture in the side wall. Such a design can be stronger and more durable than conventional portholes. The pool can also have portability and storability characteristics that are superior to those of conventional pools.

An air passageway system (100) includes an annular air delivery passageway (132), a linear air delivery passageway (112b), and one or more air injection passageways (134a-1341, 116). The annular air delivery passageway (132), the linear air delivery passageway (112b), and the one or more air injection passageways (134a-1341, 116) are constructed from flexible polyvinyl chloride walls.

The present invention provides an inflatable swimming pool convenient for drainage, which comprises an air chamber layer and a bottom pad. The air chamber layer defines an approximate rectangle with two long sides of the rectangular air chamber layer recessed inwards. The bottom of the air chamber layer is closed at a bottom plane by the bottom pad to form a pool structure, and after water is filled between the air chamber layer and the bottom pad, the two long sides of the air chamber layer can expand outwards to form a straight rectangular pool. An accommodating chamber is further arranged in the air chamber layer. The air pump is communicated with an inner cavity of the air chamber layer through an inflation communication pipe. The inflatable swimming pool of the present invention is more convenient to use, has better drainage efficiency and can be inflated automatically.

A lighted inflatable apparatus including: a wall comprising a first inflatable chamber; at least one lighting element disposed within the wall, the at least one lighting element configured to emit light; and a control box connected to the at least one lighting element, the control box configured to control one or more emission states of the at least one lighting element.

A waterfall system includes a housing. The housing comprises one or more retention legs and one or more mounting arms. Further in accordance with this aspect, the system also includes a water sprayer, a water collection attachment, and a pump coupled with the water sprayer. Still further, the housing is arranged proximal a spa and is held in place by the one or more retention legs. Additionally, a water collection attachment collects pressurized water from the spa and provides the water under pressure to the water sprayer, which is mounted above the spa by the one or more mounting arms and sprays the water into the spa.

A blow-up swimming pool that has an inflatable wall structure, a fan conductively coupled to the wall structure, a one-way air valve, and a blower control system for controlling the fan and the one-way air valve. The one-way air valve is disposed between the blower control system and the inflatable wall structure.
