Ventilated enclosure with vortex baffle

Номер: US20130090049A1
Автор: Lawrence Robert Meisenzahl
Принадлежит: Individual

A ventilated enclosure includes a vortex baffle to harness the turbulence of air in a way that uses less exhaust air while still providing ample protection to the user. The vortex ventilation system uses the total interior shape and proportion of the ventilated enclosure to direct the motion of air flow in a manner that improves efficiency. The vortex ventilation baffle can enhance the way air naturally curls, or rolls, as air flows through the enclosure. The vortex baffle can cause a mono-stable vortex to from in the enclosure. This vortex is resilient to disturbances that cause ventilated enclosures, such as chemical fume hoods, to spill. The stable vortex is above the work surface and less affected by the way apparatus is loaded inside the enclosure. The vortex baffle achieves better containment (improved safety) at lower exhaust flow (improved energy consumption) as compared to conventional ventilated enclosures.

Автор: Alison Marwitz, George Milyo, JR., Jared R. Freudenberg, John Achzet
Принадлежит: ECOLAB USA INC

Many import and export regulations require fumigation of goods, such as products or commodities, to ensure that non-native pests are not introduced. The fumigating process can involve placing the goods in a sealed containment system, and introducing the sealed good to a fumigant, such as methyl bromide gas, for a predetermined amount of time. After fumigation, regulations may require how to dispense the fumigant. The fumigant can be exhausted through fans, baffles, dampers, filters, and a chimney, as part of an emission system, in a controlled manner. The controlled manner can include combining the fumigant with ambient air and releasing or exhausting the combination over an amount of time, which mitigates pollution by the fumigant. The time-period is not specific, and instead is the time needed to meet regulatory requirements.

A temperature control system includes a temperature switch, an air outlet valve, an air inlet valve, and a control device. The temperature switch is utilized to detect and determine the external temperature and internal temperature of a container. The control device receives a first and a second signal and determines whether the air outlet valve and the air inlet valve are opened or closed. When the control device receives the first signal, the control device opens the air outlet valve and the air inlet valve, when the control device receives the second signal, the control device closes the air outlet valve and the air inlet valve. 1. A temperature control system for a container , comprising:a temperature switch for detecting and determining an external temperature and a internal temperature of the container, wherein when the internal temperature is greater than the external temperature, the temperature switch outputs a first signal, and when the internal temperature is less than the external temperature, the temperature switch outputs a second signal;an air outlet valve;an air inlet valve; anda control device for receiving the first and the second signals and controlling the air outlet valve and the air inlet valve, wherein when the control device receives the first signal, the control device opens the air outlet valve and the air inlet valve, and when the control device receives the second signal, the control device closes the air outlet valve and the air inlet valve.2. The temperature control system of claim 1 , wherein the air outlet valve is set on a top wall of the container and the air inlet valve is set on a bottom of the container.3. The temperature control system of claim 1 , wherein the temperature switch comprising:a first hollow sphere made of heat-conductive material;a second hollow sphere same as the first hollow sphere;a communication pipe made of non-heat-conductive material and communicating with the first and second hollow spheres sealed;a first ...

The indoor ventilation exhaust system is configured for use in a domestic space. The indoor ventilation exhaust system is configured for use with second-hand smoke. The indoor ventilation exhaust system draws atmospheric gases containing second-hand smoke out of a domestic space. The indoor ventilation exhaust system comprises an manifold, discharge system, and a collection network. The discharge system attaches to the manifold. Each of one or more collection networks attach to the manifolds. The discharge system creates a partial vacuum that draws the second-hand smoke of out the domestic space into the collection network. The second-hand smoke is aggregated in the manifold and is then discharged from the domestic structure containing the domestic space through the discharge system. The discharge system creates the partial vacuum that transports the second-hand smoke. 1. A forced air ventilation system comprising:wherein the forced air ventilation system comprises an manifold, discharge system, and a collection network;wherein the discharge system attaches to the manifold;wherein the collection network attaches to the manifold;wherein the forced air ventilation system is configured for use in a domestic space;wherein the forced air ventilation system is configured for use with second-hand smoke;wherein the forced air ventilation system draws the second-hand smoke out of a domestic space;wherein the second-hand smoke is transported through the manifold;wherein the second-hand smoke is discharged from a domestic structure containing the domestic space by the discharge system;wherein the discharge system creates a partial vacuum that draws the second-hand smoke of out the domestic space into the collection network.2.
