Described may be a modular network communication system for use in a foundational structure, for the inclusion of new foundational structure construction, or configured for mobility between different foundational structures. The network communication system may be configured to support a broad array of network-related communications. The foundational structure's modular network communication system may have a controller, a power connection point, a communication protocol, and may include one or more than one network node. The controller unit may have processing circuitry and may be configured to utilize a communication protocol for controlling the foundational structure's information flow of the modular network communication system. Additionally, the controller may be further configured to communicate with at least one, but also more than one network-connected device which may or may not be connected to the internet.

A detector assembly for a duct of a heating ventilation and air conditioning system includes an outer housing having at least one through hole formed therein, an inner sampling support receivable within a hollow interior of the outer housing, and at least one detector mounted to the inner sampling support. The at least one detector is axially aligned with the at least one through hole when the inner sampling support is installed within the hollow interior of the outer housing. The at least one detector is operable to sample air within the duct to detect a hazardous condition.

An energy recovery ventilator for a heating or cooling system includes a housing and a heat exchanger located in the housing for recovery of thermal energy from a stale airflow of the heating or cooling system. An exhaust fan positioned in the housing is in flow communication with the heat exchanger to urge the stale airflow from a return port disposed in a first side panel of the housing, across the heat exchanger and toward an exhaust port of the energy recovery ventilator. The exhaust fan and the heat exchanger are configured such that the heat exchanger is removable from the housing via a front panel opening in the housing without disturbing a position of the exhaust fan.

A mode switcher includes at least one mode conversion branch. The mode conversion branch includes: a liquid pipe section, a high-pressure gas pipe section and a low-pressure gas pipe section. The mode switcher further includes a high-pressure electronic expansion valve and a low-pressure electronic expansion valve, the high-pressure electronic expansion valve and the low-pressure electronic expansion valve are respectively arranged in series in the high-pressure gas pipe section and the low-pressure gas pipe section, so as to gradually be opened and closed during air conditioning mode switching to reduce a differential pressure between before and after a mode conversion operation. A heat recovery multi-split air conditioning system and control method are further provided.

An indoor unit of an air-conditioning apparatus includes a fan unit having an axial fan and a motor that drives the axial fan. The indoor unit also includes a pair of support arms on a back plate constituting a back surface of a casing. The fan unit is supported by the pair of support arms from the below.

A personal ambient air temperature modification, filtration, and purification system that is configured to be handheld. The personal ambient air temperature modification, filtration, and purification system of the present invention provides a container with air inlets to allow an internal motorized air movement mechanism to pull air through an air channel fluidly coupling to the air inlets, through a filter disposed in the air channel, through thermal diffusion blades, across at least one combination fluid vapor source and thermal energy storage component that purifies the air by vapor capture, into a thermal energy concentrator disposed in the interior volume of the container that modifies air temperature, and through the motorized air movement mechanism, where the air is then delivered into an environment as purified, filtered, temperature modified air.

A split liquid desiccant air conditioning system is disclosed for treating an air stream flowing into a space in a building. The split liquid desiccant air-conditioning system is switchable between operating in a warm weather operation mode wherein the system provides cooling and dehumidification, and a cold weather operation mode wherein the system provides heating and humidification, as well as into a mode wherein the system provides heated, dehumidified air to a space.

A chamber is provided. The chamber includes a Faraday shield positioned above a substrate support of the chamber. A dielectric window is disposed over the Faraday shield, and the dielectric window has a center opening. A hub having an internal plenum for passing a flow of fluid received from an input conduit and removing the flow of fluid from an output conduit is further provided. The hub has sidewalls and a center cavity inside of the sidewalls for an optical probe, and the internal plenum is disposed in the sidewalls. The hub has an interface surface that is in physical contact with a back side of the Faraday shield. The physical contact provides for a thermal couple to the Faraday shield at a center region around said center opening, and an outer surface of the sidewalls of the hub are disposed within the center opening of the dielectric window.
