An environmental control unit, such as an HVAC or heat pump unit, includes a housing which contains four main components: a blower which draws air into the housing via an air inlet and exhausts air from the housing via an air outlet; a first heat exchanger that exchanges heat through the air and is located between the air inlet and the blower; a second heat exchanger, which exchanges heat through water and is disposed in the second area of the housing; and a compressor. The environmental control unit having a predetermined set of parts can be arranged in multiple configurations to meet installation requirements, where configurations include air entering from the left side or, alternatively, from the right of the environmental control unit. The configurations utilize the same parts and provide front-facing access to fluid connections and the control board.

An air-to-air heat pump system for a heating, ventilation and air conditioning (HVAC) system for a building includes a thermally insulated cool channel for pumping external air into the building, the cool channel having a volume for mixing external air with exhaust air of the building, a warm channel for pumping internal air, the warm channel including a cellular humidifier that restores humidity to internal air, heat pump coils located in the cool channel and the warm channel, the heat pump coils configured for transferring thermal energy from the cold channel to the warm channel, a first fan located in the cool channel and a second fan located in the warm channel, wherein the first and second fans are configured for moving air within a channel, all of the foregoing provided in a monoblock or Split structure located inside, or partially inside, a thermal circuit of the building.

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, 143 installed 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. The air management allows customization of air flow. The housing 10 of the furniture-type air management device may be installed on the floor of the livable space and may have a hexahedron shape that extends from side to side. 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 plurality of passage openings 302 may be formed in a filter frame 301, and filters 320, 330, and 340 are stacked over the passage openings 302.

An electrically conductive plastic (ECP) material can be used to heat water in a reservoir of a respiratory humidifier to encourage heating and/or humidification of gases passing through the respiratory humidifier. The electrically conductive plastic material can at least in part overmould the base and/or walls of the chamber and/or the reservoir of the respiratory humidifier. The reservoir can also partially or fully be formed from the electrically conductive plastic material. Furthermore, the humidification system can be configured to create substantially equal or differential heating of water in the reservoir.

A ceiling fan comprising an image capture device. The image capture device operable to capture one or more images depicting at least a portion of a room or area in which the ceiling fan is located.

A heating, ventilation, and/or air conditioning (HVAC) unit may include a supply fan section having a supply fan disposed therein to force a supply air flow through a discharge plenum of the HVAC unit. The HVAC unit may also include an economizer positioned adjacent the supply fan section to receive an outdoor air flow and direct the outdoor air flow into the supply fan section.

A building management system includes a meter configured to provide data samples of a real point. The real point corresponds to a first physical parameter measured by the meter. The building management system also includes an analytics circuit configured to store a real point object representing the real point and store a meter object representing the meter. The meter object includes a points attribute that lists one or more point objects associated with the meter object including at least the real point object. The analytics circuit is also configured to store a virtual point object representing a virtual point. The virtual point corresponds to a second physical parameter not measured by the meter. The analytics circuit is also configured to update the points attribute in the meter object to list the virtual point object as one of the point objects associated with the meter object.

An air conditioning system includes a plurality of air conditioning indoor units installed in a target space, a plurality of remote control devices corresponding to the air conditioning indoor units, and a controller. The remote control device has a command input to set the corresponding air conditioning indoor unit or the remote control device. The controller performs a process based on the command input to the remote control device. Each remote control device includes a communicating unit that performs a communication with the corresponding air conditioning indoor unit, and a short range wireless communicating unit that performs a short range wireless communication with a communicating apparatus having a function of the short range wireless communication. The command is input by receiving a signal transmitted from the communicating apparatus by the short range wireless communication, at the short range wireless communicating unit.

Disclosed herein are an air conditioner system and a controlling method thereof. In a situation that air-conditioning systems such as air conditioners and refrigerators are installed and operated in a site, real-time operation data are acquired and the air conditioning and efficiency are calculated at the site. By comparing performance data provided by a device manufacturer and the real-time operation data, device performance is corrected for the site's installation environment. By using corrected device performance, it is possible to save building facility energy by providing optimal operation number control suitable for the installation environment.
