Connector Fans | for a Pleasant Room Climate Illustration of the Air Flow and Air Propagation in Corridor and Room Connector fans | For a pleasant room climate illustration of the air flow and air propagation in corridor and room. Proven technology is convincing More than 2000 connector fans already installed ensure optimum air quality in pri- vate and business premises every day. They are hardly perceptible and yet powerful in their effect. – The connector fan is barely audible, no matter whether you are sleeping relaxed at night at a whisper-quiet 21 dB(A) or when you are working at 24 dB(A). Unpleasant noise from the ventilation system is thus a thing of the past. – Connector fans are at least as good a sound barrier as a closed door. Outside noise thus stays the other side of the door. – The amount of air to be exchanged is adjusted to the needs of the user (up to 200 m³/h), whereby the same air volume is always guaranteed during operation. Optimum air quality with connector fans Connector fans enhance the benefits of mechanical ventilation. The elements are integrated into doors or walls and change air almost silently between corridor and rooms. The result is effective and demand-oriented ventilation. All this without air ducts on each storey. Combined ventilation is a more efficient way to ventilate homes and offices than conventional air distribution. Used correctly, connector fans help reduce the supply air volume considerably. Connector fans are only in operation when people occupy a room. Occupied rooms in turn receive an above-average amount of air. Supply air in the room Connector fans ensure comfortable mixing of the supply air with the room air, so that the entire roomair is well distributed. The comfort conditions are achieved only a few centimetres away from the supply air outlet. Connector fans are only in operation if the door is closed or if a room is occupied. This directly helps to reduce the total amount of air, meaning that the ventilation units and ducts on the customer side can be dimensioned about 30 % smaller. Air quality At the floor, the CO2 concentration is between 400 and 500 ppm, at the exhaust air vent height between 800 and 900 ppm. This results in a source air flow similar to that in the occupied zone, with correspondingly high ventilation efficiency. In the corridor, under the ceiling, the exhaust air concentration is between 700 and 800 ppm. The supply air on the floor and the exhaust air under the ceiling mix only minimally. illustration of the air flow and air propagation in corridor and room.

Highly versatile – Ventilation through doors and in offices and apartments walls The advantage of connector fans is that they can be used in doors and walls thanks to their simple technology. This allows them to be used both in living rooms and in the office. In doing so, they cater for all the various requirements. The modular product family can be adapted to the widest possible variety of applications and specifica- tions in no time at all, thus enabling individual solutions that ideally fulfil the requirements. The benefits are obvious: – Simple and quick to implement, even for the most varied requirements – Can be harmoniously integrated into the overall appearance – Because there is simply no better solution Where are the limits? Connector fans cannot be used between two different fire compartments Ventilation through doors and walls Ventilation through the doors: connector fans extend the function of Ventilation through the wall: connector fans are integrated directly the door to a ventilation element. Increased air movement can only be into walls when larger air volumes and even better sound values are detected near the closed door. The occupied area is thus optimally and required.

Steele February 25, 1988 Blacksburg, Virginia I Investigation of a Simulation Modelfor Peanut Drying lncorporating Air Recirculation bv _ Gamalathge Don Kulasiri D. H. Vaughan, Co-Chairman _ Agricultural Engineering (ABSTRACT) Virginia type peanuts were dried in three laboratory dryers to verify a simulation model based on Troeger and Butler’s drying equations. The energy saving potential of air recircu- lation was also investigated. Four tests consisting of eleven drying experiments were con- ducted in Fall, 1986. Two air recirculation schedules were employed and three average air flow rates were used. An experimental procedure was developed to measure input and output parameters of the drying system. The weight loss of the top layer of the peanut bed was re- corded with a data acquisition system. The electrical energy input to the heaters was also recorded. Based on the analysis of the data, the following conclusions were made: (1) The Troeger model predicted a lower moisture release rate than the actual rate for Virginia type peanuts. (2) lf the break points in the Troeger model were changed to 0.20 and 0.70 from 0.12 and 0.40, respectively, the model predicted the final moisture content more accurately.

The material contained in this course was researched, assembled, and produced by Berner International and remains its property Purpose and Learning Objectives Purpose: An air curtain, also known as an air door, employs a controlled stream of air aimed across an opening to create an air seal. This seal separates different environments while allowing a smooth, unhindered flow of traffic and unobstructed vision through the opening. This course discusses how air curtains work and why they can contribute to occupant comfort, energy efficiency, and indoor air quality when the door is open. It also reviews how air curtains improve whole-building energy efficiency versus conventional methods. Learning Objectives: At the end of this program, participants will be able to: • describe air curtains in terms of their components, function, and operation • discuss how air curtains enhance the safety of a entrance or opening by evaluating air curtain design criteria to determine the correct size and placement of an air curtain for a specific application • explore the benefits of air curtains to determine how they improve occupant thermal comfort levels and reduce whole-building energy use • recognize why it is necessary to specify the right air curtain and controls to achieve optimal air curtain effects for environmental separation, to reduce dust, fume, and insect infiltration, and to maintain air movement control • identify industry building codes and testing standards relevant to air curtains, and • refer to case studies to illustrate the efficiency of air curtains for energy savings, climate separation, and comfortable air temperature.

  • Ventilation Parameters and Airborne Particulate
    April 2, 2021 Joe Crelier, Director–Risk Management Portland Public Schools 501 N Dixon Street Portland, Oregon Via email: [email protected] Regarding: COVID Response Indoor Air Quality Testing Report Rieke Elementary School 1405 SW Vermont Street Portland, Oregon PBS Project 25000.138 Dear Mr. Crelier: On March 24, 2021, PBS Engineering and Environmental Inc. (PBS) performed indoor air quality testing in Rieke Elementary School located at the address above. These services were provided to Portland Public Schools (District) to measure air quality parameters before schools and district-owned buildings are opened again for reoccupancy. As part of these indoor air quality testing services, PBS measured carbon monoxide (CO), carbon dioxide (CO2), temperature in degrees Fahrenheit (°F), relative humidity (%RH), and airborne particulate (PM2.5 and PM10). Additionally, PBS reviewed and inventoried accessible components of the test rooms’ heating, ventilation, and air conditioning (HVAC) systems Based on PBS’ findings, the multipurpose room and the kitchen tested below the recommended range for indoor air temperatures. These areas should be monitored for temperature complaints. The results of the testing and assessment indicates that indoor air quality in the building is good and that the building is acceptable for occupancy. While PBS observed no measurable indoor air quality concerns in any of the rooms that were tested, PBS did not test every occupiable room in each building. This investigation has been performed in concert with a concerted effort on the part of the District to perform regular inspections and repair of all HVAC mechanical systems throughout the District. Additionally, it is the District’s policy that rooms without adequate ventilation will not be utilized moving forward.
