A bathroom management apparatus is provided which has a storage cabinet and an integrated air conditioning, or dryer, module. The bathroom management apparatus includes: a cabinet forming an interior space whose front is open; a first dividing plate provided within the cabinet and dividing the interior space; a second dividing plate provided within the cabinet in parallel with the first dividing plate and dividing the interior space, and forming a storage chamber in the space between the first and second dividing plates; a duct connected to the first dividing plate and the second dividing plate, provided within the cabinet, and dividing the storage chamber; and the air conditioning module installed within the duct.

A self-insulating air delivery and recirculation system maintains a desired air temperature of the conditioned air supplied thereinto for delivery to an aircraft. The system uses insulating airflow layers; a parallel layer and a counterflow layer. A starting section connects to a PCA unit and delivers conditioned air therefrom to an interior supply hose. The starting section supplies conditioned insulating air to an interior insulating hose that is annularly outward of the supply hose and in which air flows parallel to airflow in the supply hose. A reversing connector indirectly connects the supply hose to the aircraft and reverses the flow of air from the interior insulating hose to flow back toward the PCA unit in an exterior counterflow hose that is annularly outward of the interior insulating hose and connects at its far end to provide intake airflow to the PCA unit.

A transportable building comprising a modular element constructed from a plurality of steel or aluminum intermodal shipping containers is disclosed. The method of manufacture greatly reduces the cost of constructing the transportable building. The transportable building can be set up at a site and later easily dismantled and moved, providing flexibility to temporarily set up a business without the need to build and maintain a permanent structure.

Provided are a flexible insulated air duct and a modular flexible insulated air-duct system; the flexible insulated air duct includes an air-duct main body (1); the air-duct main body (1) includes an inner air-duct layer (5) and a heat-insulating layer (4) integrally formed on the inner air-duct layer (5); the inner air-duct layer (5) is arranged inside the heat-insulating layer (4), and the heat-insulating layer (4) is a rubber/plastic material. The modular flexible insulated air-duct system made by assembling a main air duct (7), a branched air duct (8), and a connecting air duct (9) may be rapidly connected on-site using a zip fastener to form an air-duct system having any configuration.

A self-insulating air delivery system maintains a desired air temperature of the conditioned air supplied thereinto for delivery to an aircraft. The system uses insulating airflow layers; a parallel layer and a counterflow layer. A starting section connects to a PCA unit and delivers conditioned air therefrom to an interior supply hose. The starting section also either creates bleed conditioned air or accepts conditioned insulating air and supplies it to an interior insulating hose that is annularly outward of the supply hose and in which air flows parallel to airflow in the supply hose. A reversing connector indirectly connects the supply hose to the aircraft and reverses the flow of air from the interior insulating hose to flow back toward the PCA unit in an exterior counterflow hose that is annularly outward of the interior insulating hose.

A prefabricated outdoor thermal duct system is provided having a metal formed ductwork air passage, a hard board insulation layer glued to the metal duct leaving custom cut space for duct connections, a custom prefabricated cladding formed and adhered to the hard board insulation, a custom fabricated insert matching the insulation material, installed over the duct connection in the field to seal the joint, and a final fabricated cap adhered to the cladding.

A wall sleeve system for a ventilation system comprises one or more assemblies constituted in a modular manner, which can be flexibly combined with one another.

A funnel system for redirecting cool air from a window-mounted, air conditioner helps to cool another room effectively without requiring a second a/c unit in the other room. The funnel system is telescopingly adjustable to mount to different sized a/c units from different makers. The system utilizes a unique rail without damaging or modifying the a/c window unit.

A road vehicle with a vehicle frame and a rear axle connected to the vehicle frame is provided with an ambient air purification device with filter elements for removing dust, particulate matter, and gases from ambient air. The ambient air purification device is arranged transverse to a longitudinal vehicle axis in an exterior region of the road vehicle at a vehicle rear of the road vehicle in an underfloor region such that at least the filter elements are arranged behind the rear axle of the road vehicle in a travel direction of the road vehicle. The ambient air purification device is received in an installation space of the vehicle frame. The ambient air purification device is flowed through in longitudinal vehicle direction. A free outflow zone of the ambient air purification device is arranged, in travel direction of the road vehicle, behind the ambient air purification device.

An air conditioner indoor unit is provided. The air conditioner indoor unit includes: a base module, having a base part which is arranged with a fan motor; a heat exchange module having a heat exchanger and a connection pipeline for connecting the heat exchanger to an air conditioner outdoor unit; the heat exchanger and the connection pipeline are arranged in such a way that in a mounted state, the heat exchanger and the connection pipeline are entirely located at a front side of the base module; an air and water duct module having an air duct assembly; the air duct assembly is suitable to be entirely disassembled from the base part without disassembling the fan motor in the base part. During mounting, pre-assembly is first performed and then general assembly is performed; in such manner, the time needed to assemble the whole unit may be reduced.
