A HEPA/VOC air handling system is disclosed. It has a HEPA air filtration unit and an air handling unit. The HEPA air filtration unit has a fresh air intake, an inside air intake, a pre-filter unit, a HEPA air filter, and HEPA fan. The HEPA fan draws fresh air and inside air into a HEPA chamber to form combined air that moderates the fresh air toward the inside air's temperature and humidity to inhibit shocking or damaging the components in the HEPA air filtration unit. The combined air passes through the pre-filter unit and then the HEPA air filter to form HEPA filtered combined air. The air handling unit has a HEPA filtered combined air intake, a return air intake, an air handling device fan, and a supply outlet wherein the HEPA filtered combined air mixes with the return air to (A) form mixed air and (B) further moderate the HEPA filtered combined air toward the return air's temperature and humidity to inhibit shocking or damaging the components in the air handling device, and the rooms that receive the mixed air.

Environmental control systems, airflow interleavers, and methods. The environmental control systems include an airflow interleaver and mix manifold comprising a mixing chamber. The airflow interleaver comprises a first airflow guide structure configured to guide a second airflow towards a central axis of the mixing chamber and a second airflow guide structure configured to guide a first airflow away from the central axis. The methods include channeling first and second airflows to the mix manifold, mixing the first and second airflows, which includes guiding the first airflow away from the central axis and guiding the second airflow towards the central axis. The airflow interleavers include a tubular body, and a plurality of converging airflow guides and a plurality of diverging airflow guides extending from the tubular body and collectively being configured to interleave first airflow streams flowing from the tubular body with second airflow streams flowing external to the tubular body.

The present invention discloses an air conditioning (AC) system, which comprises an indoor ventilation device, at least one air-supply chain and at least one cascading duct. The indoor ventilation device comprises a main blower. Each of the at least one air-supply chain comprises “n” sub air-supply regions each having at least one air inlet and at least one air outlet. Each of the at least one cascading duct is used to one-by-one cascade each of the “n” sub air-supply regions by sequentially connecting with the at least one air inlet and/or the at least one air outlet of each of the “n” sub air-supply regions, wherein “n” is an integer and “n”>1 and at least one of the at least one cascading duct is a partition wall connecting any two sub air-supply regions.

A heating, ventilation, and/or air conditioning (HVAC) unit includes a terminal unit. The terminal unit includes a housing having a first panel bordering a return airflow path, a second panel bordering an additional airflow path, and a separating wall disposed between and bordering the return airflow path and the additional airflow path.

An apparatus and method powered by compressed fluid, which preferably provides both air conditioning and power generation. The apparatus includes a fluid conduit of substantially elongate form (51), a helical accelerator (80), a substantially elongate distributor body (53) associated with said accelerator (80), wherein at least part of said distributor body (53) is positioned substantially coplanar to said fluid conduit (51), and a TEG device (55), positioned intermediate said fluid conduit (51) and said distributor body (53). In use, a compressed fluid (70) is supplied to an inlet (60) of said helical accelerator (80). The accelerator (80) causes the fluid (70) to form a vortex inside said distributor body (53) and thereby produce a hot fluid stream (71) and a cold fluid stream (72). The hot fluid stream (71) is directed to flow adjacent to a wall of said distributor (53) to thereby heat said distributor wall. The cold fluid stream (72) is at least partly directed to flow via said accelerator (80) to cool said fluid conduit (51), and, to cool a surrounding environment. A temperature differential is thereby created between said distributor wall and said conduit (51), to generate power in the TEG device (55).
