A previous ASHRAE investment predicts the energy use associated with filtration. The measured data in 825-RP “A Standard Simulation Test Bed for the Evaluation of should be used to validate the model. Control Algorithms and Strategies” could be leveraged to reduce the effort required to adapt a simulation tool for the project. 1311-RP 1312-RP 09/05 – 01/09 University of Illinois Urbana-Champaign Principal Investigator: Xinlei Wang TC 2. 2, Plant and Animal Environment Research Strategic Plan Goals Supported: A6, B1, B2, B4, C3, C4, C5, D4, E1 1301-RP Quantification and Ventilation Effectiveness for Air Quality Control in Plant and Animal Environments Ventilation effectiveness measurement plays an important role in 04/05 – 01/09 establishing a comprehensive baseline of ventilation performance Kansas State University in large animal buildings.

Goals Supported: A1, Comparison of Gas Phase Air Filtration (GPAFE) Lab Tests to Field Experience This project will create correlations between media performance comparisons generated at higher concentrations (accelerated tests in lab environments) and comparisons generated at low concentrations (as would be found in real-world IAQ applications).The completion of this project will provide the ASHRAE membership with confidence in media comparisons generated using accelerated testing, such as that described in testing standards being generated by ASHRAE subcommittees: SPC-145.1 (loose media), SPC145.2 (full-filter), and SPC-145.3 (field testing). This project provides direct support to the SPC-145.1 test standard for loose media.While SPC 145.1 is not waiting on this research before approval, the research will aid in the translation of the results to real-world applications. It will also provide the basis for further research regarding prediction of useful life of GPAFE based on these lab results. 1316-RP 06/05 – 01/09 University of Denver Principal Investigator: Donald Stedman TC 2. 3, Gaseous Air Contaminants and Gas Contaminant Removal Equipment Research Strategic Plan Goals Supported: A6, B2, B4, C3, C4, D5, E1 1302-RP Experimental Evaluation of the Heat Transfer Impacts of Tube Pitch in a Highly Enhanced Surface Tube Bundle Fundamental understanding of boiling in tube bundles and comprehensive predictive models form the basis from which flooded evaporators are designed across the HVAC&R industry.It is envisioned that the results generated by this project would serve to validate existing and future modeling techniques and simultaneously expand fundamental understanding by examining tube pitch, a variable often overlooked in both the scientific study and design of flooded evaporators.Focusing on the effect of tube pitch and localized wetting is driven primarily by the application of a large flooded evaporator such as would be found in larger commercial air conditioning or refrigeration applications.The equipment typical to this type of application has among the highest initial costs and C1, D1, D3, E1 the highest energy utilization of any in the HVAC&R industry.ARI statistics suggest the global market size for centrifugal chillers with cooling capacities over 500 tons can be estimated at approximately $390 million for 2004. This represents a significant investment by much of the ASHRAE community, including both manufacturers who design and manufacture the equipment and by customers who purchase it.In addition, the energy costs associated with operating this type of equipment over a 20–25 year life cycle will typically be much greater than the initial capital expense.By further improving the understanding of boiling in tube bundles, it will be possible for equipment manufacturers to improve both design methods and equipment that uses flooded evaporators.Because of the magnitude of the costs (both direct and long term energy costs) associated with this equipment, even incremental improvements in evaporator design can provide tangible benefits.These benefits extend through ASHRAE and beyond by allowing the construction and installation of more efficient HVAC&R equipment at a constant cost or lower cost equipment at the same efficiency level. Laboratory Testing of Duct Fittings to Determine Loss Coefficients The intent of this research is to improve the ASHRAE database by testing fittings not in the database.The TC 5.2 subcommittee responsible for the database has identified fittings in this category.This will improve the ASHRAE Duct Fitting Database allowing designers to: (1) accurately select fittings from a large diverse set of information, and (2) improve the use of duct design programs that use the database. More reliable data and/or a large database of fitting loss coefficients will help members to better design ductwork for their clients, enabling more accurate pressure drop calculations and less safety factor.This will allow fans to be sized properly, reducing energy consumption and wasted material.It should also generate an increase in sales for the ASHRAE Duct Fitting Database and ASHRAE’s T-DUCT optimization design program marketed as a package. 04/06 – 01/08 (P) TNO Environmental and Geosciences Principal Investigator: JBGA Havermans TC 9.3, Transportation Air Conditioning Research Strategic Plan Goals Supported: B1, B2, B4, C5, D5, E1, E2 1306-RP Incident-Response Monitoring Technologies for Aircraft Cabin 01/06 – 10/08 Air Quality Research is needed to strengthen the role of a new ASHRAE Tennessee Technological Institute Standard (ASHRAE 161) that will address incidence response Principal Investigator: monitoring in aircraft.
