Variable rate heating for agricultural purposes

Номер: US20120312885A1
Автор: Carl A. Lind, John L. Tomlinson
Принадлежит: Lb White Company Inc

An exemplary temperature control system for animal confinement buildings includes an agricultural heater and a ventilation system. The agricultural heater is modified to be a variable rate heater using SmartBox technology or by applying appropriate control logic and outputs to a conventional room controller. A heat on/off relay of the room controller can serve as an enable signal connected to the SmartBox. Heating is controlled using a proportional-plus-integral algorithm for error correction. Error correction may be ceased when temperatures fall within a dead band. Heat is turned on when the temperature drops to an on temperature equal to a set point minus 0.5 F. Heat can be turned off when the heater has been at a minimum output level for a minimum output period (such as 90 seconds) and the temperature has not dropped below the on temperature during the minimum output period. An auto-variable radiant brooder may be incorporated.

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: BREEN Michael Scott
Принадлежит: GOVERNMENT OF THE UNITED STATES AS REPRESENTED BY THE ADMINISTRATOR OF THE U.S. ENVIRONMENTAL PRO

A real-time system and method for personal air pollution exposure and inhaled dose management is described. A personal device (e.g., smartphone) determines personal exposure and inhaled dose metrics (e.g., daily accumulated dose), and compares daily histories of these metrics with personal health histories (e.g., self-reported daily asthma symptoms/inhaler use) to provide notifications when adverse health effects (e.g., asthma exacerbation) are likely to occur. The system notifications provide a personalized exposure/dose management tool by recommending behavioral changes to reduce exposure/dose (e.g., change time-location, time-physical activities, building operation). These behavioral changes are then used by the system to modify the real-time exposure and dose determined by the system. 1. A personal device of a user which receives geocoded outdoor air pollution and outdoor weather condition data from outdoor sensors , personal condition data from wearable sensors , the personal device comprising:a display unit to enable the user to enter personal information including home condition data and user characteristics;an accelerometer which detects a physical activity level of the user;a personal device locator which determines a location of the personal device; anda processing unit which uses the geocoded outdoor air pollution and outdoor wind speed and temperature data, the personal condition information, the physical activity level of the user and the location of the personal device to assess air pollution exposure and dose of the user; 'the personal device generates a notification to the user to modify behavior or at least one automated home condition that is controlled by the home condition data based upon the assessed air pollution exposure and dose of the user.', 'wherein2.

An integrated method for assessing metabolic rate and maintaining indoor air quality and efficient ventilation energy use. A physical sensor assesses room occupancy. An actuated ventilation system is set to a constant CO2 level in a predetermined healthy range, where the actuated ventilation system includes a CO2 sensor. The actuated ventilation system sets a first air ventilation rate and the sensor measures a first CO2 level. The system determines whether CO2 level is in a healthy range, if not then the CO2 level is adjusted by setting a subsequent air ventilation rate. A subsequent CO2 level is measured. If the CO2 level is determined to meet a predetermined healthy range, then an assessment of change of air ventilation rate (Δ ACH) is determined. The determination of air change rate can be further augmented by a physical pressure based measurement. The overall metabolic rate is generated.
