Charles Culp TC 5.2, Duct Design Research Strategic Plan Goals Supported: A1, A2, A6, C1, C3, C6, D1, D7, E1 run to this protocol.The experimental set-up was funded by the Air Distribution Institute (ADI) and can be used directly for the ASHRAE project.This data will also be used to update Fundamentals Handbook.Lastly, computational fluid dynamic calculations and graphics, using Fluent, are part of the larger ADI project and will be made available to ASHRAE. Method of Testing and Data Collection for Energy Characteristics of Healthcare Medical Equipment A Method of Testing (MOT) will be developed to measure energy inputs and heat gain outputs, over time, both in standby and over the cycle (or multiple cycles) of the equipment. The Method of Testing should be appropriate for submission to the ASHRAE Standards process, for adaptation and adoption as a new ASHRAE Standard. A broad range of medical equipment will be tested to the MOT, and the data will be presented for inclusion in the ASHRAE Handbooks and other resources. Waterside Fouling Performance of Brazed-Plate Condensors in Cooling Tower Applications. Perform evaporation heat transfer and pressure drop tests on plate heat exchangers with ammonia and ammonia/miscible oil mixtures at various temperatures and pressure conditions in order to develop correlations to estimate heat transfer and pressure drop. Included in the scope of experimentation are test on three different stainless steel geometrics for variable operating parameters such as temperatures, ammonia feed ratio, heat flux, oil concentration and exit quality. 04/07–04/08 IES Engineers Principal Investigator: Daniel Koenigshofer TC 9.6, Healthcare Facilities Research Strategic Goals Supported: A7, C1, C6 1343-RP GARD Analytics, Inc Principal Investigator: Jason Glazer TC 1. 5, Computer Applications Research Strategic Plan Goals Supported: C1, E1 all stages of the HVAC&R project life cycle. Based on comparison and analysis of existing data models and the GPC 20 use cases, the research will identify, characterize, and document: core data items: generally required items defined similarly in multiple data models; extension data items; items suggested by use cases but not well represented in existing models; conflicting/problem items; items that are addressed inconsistently in existing models; and mappings among existing data models; information supporting translation among existing models. This information will be presented in tabular and text form for use in the development of Guideline 20P, other standards or guidelines, and software applications. A secondary objective is to produce a demonstration implementation of automated intermodel data exchange. Methodology to Measure Thermal Performance of Pipe Insulation at Below Ambient Temperatures The overall objective of the proposed research is to design an experimental apparatus capable of measuring the effective thermal conductivity of pipe insulation systems at below-ambient temperature. The end loss, energy metering, temperature measurement, equilibration criteria, and other operational issues will conform to the requirements of Standard ASTM C 335 and the design will be discussed with the Project Monitoring Subcommittee (PMS) for approval prior to the initiation of work on any subsequent task. The PIs will produce a set of shop drawings and a parts list for the test apparatus. Biological Control in Cooling Towers Using Non-Chemical Water Treatment Devices The objective of this research project is to conduct laboratory tests using a model cooling tower system.Each system (test cell) will include a heat load, evaporative cooling, blow-down system, and water make-up.Tests are to be conducted comparing the microbiological activity (a numerical count of bacteria by heterotrophic plate count) using non-chemical device (NCD) treatment versus that with no treatment (i.e., no added chemicals) under controlled conditions. The selected methodologies will be examined for microbiological control, including both water-borne (planktonic) bacteria and surface occurring biofilm (sessile) and higher life forms (zooplankton).The contracted researcher will analyze the gathered data for each NCD tested and determine to the extent practical the mechanism of control of each device for both planktonic and sessile biological control. Revised Heat Gain and Capture and Containment Exhaust Rates from Typical Commercial Cooking Appliances The objective is to refine and expand the database on the heat gain for commercial food service equipment and, where applicable for hooded appliances, report the exhaust ventilation rate required for capture and containment. The goal is to provide reliable heat gain data for the ASHRAE Handbook to help engineers accurately calculate cooling loads for commercial kitchens. A parallel goal is to report associated exhaust ventilation rates to assist engineers with hood selection and sizing. At least 80 hooded and un-hooded equipment types will be tested. For the hooded appliances, the study will determine the radiant heat gain to space during idle (ready-tocook) conditions. For unhooded appliances, where the kitchen air conditioning load is based on total enthalpy, the data will establish the radiant and convective split for appliances including the latent contribution. Generation of Hourly Design-Day Weather Data Develop a method of generating hourly weather data profiles, 24 hours, including dry-bulb, wet-bulb, dew-point, direct solar and diffuse solar radiation for design days. The method must be applicable worldwide and generate sequences for any day of the year. The project will involve: selecting test sites from the list of sites included in the 2005 ASHRAE Handbook—Fundamentals “List of Design Weather Date,” investigating the hourly weather profiles for days that meet design conditions identifying and developing methods to generate weather profiles and evaluating their utility and practicality.This project will also investigate solar models, and similarly evaluate their utility and practicality, agree with the PMS on the best modeling approach, then test it and develop a spreadsheet implementation for use by design practitioners. Air Distribution Effectiveness With Stratified Air Distribution Systems 05/08 - 12/08 Oklahoma State University Principal Investigator: Lorenzo Cremaschi TC 8.5, Liquid-to-Refrigerant Heat Transfer Co-funding: $47,000 Air Conditioning and Refrigeration Institute (ARTI) Research Strategic Plan Goals Supported: D1 1345-RP 08/08 – 10/09 Oklahoma State University Principal Investigator: Lorenzo Cremaschi TC 1. 8, Mechanical Insulation Systems Research Strategic Plan Goals Supported: A1, A6, C1, C6 1356-RP 09/06 – 08/08 Ghulam Ishaq Khan Institute Principal Investigator: Sultan Khan TC 1. 3, Heat Transfer and Fluid Flow Co-Funding: $10,000 International Institute of Ammonia Refrigeration Research Strategic Plan Goals Supported: A8, D1, D2, D3, E1 1352-RP Evaporation in Flooded Corrugated Plate Heat Exchangers with Ammonia and Ammonia/Miscible Oil Perform evaporation heat transfer and pressure drop tests on plate heat exchangers with ammonia and ammonia/miscible oil mixtures at various temperatures and pressure conditions in order to develop correlations to estimate heat transfer and pressure drop. Included in the scope of experimentation are test on three different stainless steel geometrics for variable operating parameters such as temperatures, ammonia feed ratio, heat flux, oil concentration and exit quality. 04/08 – 10/09 University of Pittsburgh Principal Investigator: Radisav Vidic TC 3. 6, Water Treatment Research Strategic Plan Goals Supported: A4, B2, C4, D3, E2 1361-RP 09/07 – 08/09 Drexel University Principal Investigator: Jin Wen TC 1. 4, Control Theory and Application Research Strategic Plan Goals Supported: A1, C6, D1 1353-RP Stability and Accuracy of VAV Box Control at Low Flows Box manufacturers and controls vendors are under tremendous competitive pressure to reduce equipment costs. Many in the industry claim that stability and accuracy at low flow are being compromised due to cost-cutting measures. Without objective research on performance consumers will make decisions based only on price. This research will shed light on what equipment works well and what does not and give consumers the information necessary to base decisions on performance as well as price. It will also give manufacturers the incentive to improve performance and/or switch to more promising technologies. While it is not the primary objective, this research will also be valuable for developing modifications or an appendix to ASHRAE Standard 130 with a Method of Test (MOT) for VAV box velocity sensors and guidance on the use of VP amplification 04/06 – 09/07 (K-factors). This MOT is also necessary for developing an ARI 880 GARD Analytics, Inc. rating standard and reporting requirement for testing minimum flow Principal Investigator: rates and K-factors based on pre-determined minimum velocity Roger Hedrick pressure signals (e.g. 0.004”, 0.01”, 0.03”, etc). Furthermore, it is TC 4. 2, Climatic intended that this research will lead to a definition and method of Information test for the minimum velocity or velocity pressure signal at which a terminal unit zone controller can stably control, which in turn Research Strategic Plan Goals Supported: A1, could lead to an industry rating standard for zone controllers and A6, C1, C3, E1 the minimum controllable signal they require for reliable operation with specific box types. Once these two ratings are developed an engineer will be able to accurately calculate the minimum controllable flow set-point for any combination of VAV box and controller by applying the rated minimum controllable signal of the controller to the VAV box’s rated minimum flow at that signal. 04/06 – 01/09 Fisher-Nickel, Inc.
