A receptacle box for conveniently and efficiently locating the terminal ends of the refrigeration line set, condensation drain and low voltage wires leading down from an air conditioner unit during initial construction of a building, is disclosed. Specifically, a rectangular box having a top, bottom, angled back, and sides, but open on the front, and having openings on the top through which the line set, condensation drain and low voltage wires can be passed, is disclosed. The receptacle box is mounted in a cutout on the exterior wall of the building before siding is installed.

A wall- or surface-mounted light fixture with a housing containing one or more external visible light sources to illuminate the space where the light fixture is mounted, one or more UV emitters inside the housing to destroy bacteria and pathogens, and one or more fans inside the housing that recirculate the air in a space and subject the air to the UV radiation inside the housing, destroying bacteria and pathogens in the air passing though the housing.

A system passively cools, regulates humidity and/or rectifies diffusive transport of water vapor in an interior area within a structure. The system includes a membrane assembly covering a portion of the structure, wherein the membrane has an interior side facing the interior area and an exterior side. The membrane assembly defines a plurality of pores. When cooling, a supply of fluid is provided to the membrane assembly so that capillary action of the pores redistributes the fluid to create evaporation and, in turn, the desired heat flow. The membrane assembly can include an architectural membrane coated with a porous matrix coating to form the pores. A pump can provide the fluid to the interior side of the membrane assembly. Preferably, the architectural membrane is woven PTFE-coated fiberglass and the porous matrix coating is titanium dioxide, zeolites and/or silica gel.

A thermostat that is configured to be releasably secured to a wall mountable connector, wherein the wall mountable connector includes a jumper switch that permits an installer or other professional to easily form an electrical connection between different wiring terminals of the wall mountable connector in accordance with how particular field wires are connected to the wiring terminals of the wall mountable connector. The thermostat is further configured to automatically determine the position of the jumper switch of the wall mountable connector, and in some cases, change the control of at least some functionality of the thermostat and/or HVAC equipment depending on the position of the jumper switch.

An air circulation device includes a suction section configured to suck indoor air, and a blower section configured to blow the air sucked by the suction section into a room. The air is in a form of a vortex ring. The air circulation device is operable in at least a first mode in which the vortex ring blown therefrom reaches a wall surface of the room.

A ventilation air conditioning structure including a room that has a floor portion to a fourth wall portion, a first wall portion to be a building outer wall in which an air supply opening is formed in a vicinity of a third wall portion, and an air exhaust opening that is formed in a vicinity of the fourth wall portion. The ventilation air conditioning structure also includes an air conditioner that is disposed inside the room and where at least one of air sending openings of a room interior unit is capable of sending air in a direction of a second wall portion, and an external-air conditioner that is disposed outside the room. The external-air conditioner includes heat exchangers that are incorporated in a refrigerant circuit of the air conditioner via a branched pipe that is branched from a refrigerant piping and a casing that houses the heat exchangers.

A facade panel conditioning system for installation on a new or existing building is disclosed. The system includes modular panels, a structural anchor, hydronic piping, and ductwork. The panels attach to each other around the exterior of the building forming an insulated shell. The anchor attaches the panels to the building structure forming an air cavity between each individual panel and the exterior. The hydronic piping transfers heat to the air cavity and individual units of the building. The ductwork delivers ventilated air and exhaust air to the air cavity and individual units. The hydronic piping of a panel connects to the hydronic piping of an adjacent panel forming a hydronic piping system that distributes heat or cool throughout the shell. The air duct of a panel connects to the air duct of an adjacent panel forming an air duct ventilation system that distributes air throughout the shell.

The present disclosure discloses a fabricated air conditioner wall and an operation method thereof, and the fabricated air conditioner wall included a precast wall and a heat pump system embedded in the precast wall. The components of the fabricated air conditioner wall are mass-produced and assembled in factories. The fabricated air conditioner wall mainly includes an indoor heat exchanger, a throttle valve, a condensate water tank, a four-way valve, a wall-buried pipe, a compressor, and an outdoor heat exchanger. In a cooling mode, condensate water is collected in the condensate water tank to cool the refrigerant. In winter, when the precast wall is illuminated by sunlight, a temperature of an outer wall is often higher than a temperature of outdoor air, and this solar energy can be reasonably utilized by the wall-buried pipe, thereby improving the heating effect of the air conditioner itself.

A dehumidifier includes a cabinet, a compressor, an evaporator, a condenser, and a fan. The cabinet is configured to be installed between studs in a wall. The evaporator is installed within the cabinet above the compressor. The condenser is installed within the cabinet above the evaporator. The fan is installed between the evaporator and a back surface of the cabinet. The fan is configured to generate the airflow that flows into the cabinet through the evaporator and out of the cabinet through condenser. The airflow flows through the evaporator and condenser in order to provide dehumidification to the airflow.

In the field of building and of cooling systems there is disclosed a wall-mounted radiant cooling device for rooms, including: at least two cooling tubes positioned on two different levels adapted for cooled water to flow through; a fixing unit of the cooling tubes to the outside of the walls of the rooms. Each cooling tube includes two shaped longitudinal fins, and the radiant cooling device further includes a channel, arranged parallel to and underneath the cooling tubes, adapted to collect the condensate that is generated through contact with the hot air present in the rooms provided with the cooling tubes. The longitudinal fins of the cooling tubes are adapted to cooperate with one another to convey the condensate into the channel.
