The International Energy Agency (lEA) was established as an autonomous body within the Organisation for Economic Cooperation and Development (OECD) to administer that agreement. Twenty-one countries are currently members of the lEA, with the Commission of the European Communities participating under a special arrangement. As one element of the International Energy Program, the Participants undertake cooperative activities in energy research, development, and demonstration. A number of new and improved energy technologies which have the potential of making significant contributions to our energy needs were identified for collaborative efforts. The lEA Committee on Energy Research and Development (CRD), assisted by a small Secretariat staff, coordinates the energy research, development, and demonstration programme.

  • Product Catalog -Vertical Stack Fan Coil Units
    Product Catalog Vertical High Rise Fan Coil Units — FCV 0.75 to 3 tons June 2021 UNT-PRC028D-EN Introduction Vertical High Rise Fan Coil Units Trane vertical high rise fan coils are intended for single zone applications. These units are used in high rise hotels, and condominiums. We work closely with engineers at the design stage to ensure optimum use of the units within the HVAC system. These units have load capabilities of 300 to 1200 cfm. Fan coils provide cooling and heating, and are available as two-pipe, with or without electric heat (one hydronic circuit) or four-pipe (two hydronic circuits). These units feature a variety of factory mounted piping packages. The UC400-B controller is included inside the unit's control box assembly. These controllers utilize analog signals from a control device mounted in the occupied space. The Customer Supplied Terminal Interface (CSTI) option, includes a 24volt AC transformer, and an interface terminal board. Controls provided by an external source can be tied into the interface terminal board utilizing the integrated terminal block with 3mm screw connections. The Customer Supplied Terminal Interface (CSTI) option is also available with a Telkonet thermostat. A thermostat with wire harness will ship with the unit and can be connected to the unit via a connector in the field after the unit is installed. Figure 1. Fan coil - model FCV Figure 2.

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.
