Additionally, alternatives to EPA method 5 to quantify the grease vapor emission from cooking processes will be evaluated. The scope is to expand the existing grease emission database determined in 745-RP by applying a similar test method to include additional appliances found in typical commercial kitchens. 09/07– 08/09 Kansas State University Principal Investigator: Donald Fenton TC 6.9, Thermal Storage Research Strategic Plan Goals Supported: A1, C6 1388-RP 09/07 – 08/08 University of Minnesota Principal Investigator: Thomas Kuehn TC 5.10, Kitchen Ventilation Research Strategic Plan Goals Supported: A1, A5, A7, B2, C2, C6, D1 1376-RP Method of Test to Evaluate Field Performance of Commercial Kitchen Ventilation Systems Short Term Curtailment of HVAC Loads in Buildings Through laboratory research and follow-up field testing, develop IThe objective of this project is to identify and evaluate peak demand 09/08 – 04/10 reduction strategies, formulated in response to short notification of a document that defines a complete method for evaluating field Florida Solar Energy Cen- critical peak rates and time-of-use charges from utilities, for use in performance of commercial kitchen ventilation systems which ter/University of Central commercial buildings.

Recommendations Based on Field Testing and Analysis of HighAltitude Installations of Gas-Fired Boilers and Water Heaters Based on first-principle work and recommendations reported in the Gas Research Institute topical report “High Altitude Installation of Natural Gas-Fired Appliances with Fan-Assisted Combustion Systems GRI-95/0014”, determine whether less derating than is currently prescribed can be safely permitted for operating natural gas-fired and propane gas-fired boilers and water heaters at highaltitude. Determine the applicability and validity of National Standard of Canada CAN/CGA-2. 17-M91, Gas-Fired Appliances for Use at High Altitudes, section 2. 2 for use in testing appliances at near sea level (0 to 2,000 feet altitude) to demonstrate robustness at high altitude (2,000 to 10,000 feet altitude). Investigate alternate testing and prediction methods, which may be used to provide equivalent high altitude performance and validation. 1390-RP 04/06 – 10/08 University of WisconsinMadison Principal Investigator: Greg Nellis TC 6.8, Geothermal Energy Utilization Research Strategic Plan Goals Supported: A1, A2, A3, A6, C1, C3, D1, E1 1384-RP A6, C6, C7, D1 Development of Design Guidelines for Hybrid Ground Source Heat Pump Systems The overall objective of this project is the development of systematic design guidelines and tools that will reduce the uncertainty associated with sizing hybrid ground-source heat pump (HyGSHP) systems. The initial objective will be identification of the most attractive HyGSHP configurations and relevant operating conditions. Subsequently, we will develop a detailed and physics-based simulation tool that can be used to evaluate alternative control strategies and optimize a HyGSHP system for a particular application through minimization of the life-cycle cost. The simulation tool will be used to carry out parametric studies over a range of relevant conditions (buildings types and climates); these results will be correlated in order to provide design guidelines in terms of a set of charts or correlations that encompass the most widely applicable systems and conditions. Additionally, the simulation tool will be made available as a distributable program with graphical user interface that can be used by engineers with no specific knowledge of the program itself in order to accomplish design studies over arbitrary conditions. The eventual result of this work will be the extension of ground-source heat pump systems to heavily heating and cooling dominated climates through hybridization. Thermal Energy Storage Design for Emergency Cooling With the expansion of cooling demands in emergency situations in a majority of cases driven by the possibility of electronic equipment shutting down whether it be hospitals or data centers, designing backup/emergency cooling systems is becoming routine for building designers. In fact, the emergence of new TCs like TC 9.9, Mission Critical Applications, is indicative of the expanding interest and role of ASHRAE in emergency applications. However, at present, there is a large gap in design guidelines for incorporating “standard” technologies like TES with the requirement for these applications. This project hence would provide guidelines not just for incorporating TES, but also for other technologies through better understanding of load requirements and management. In turn, it is expected that the design requirements, so obtainedwould provide guidance to manufacturers and practitioners of TES systems to more optimally design and implement TES systems, not just for traditional benefits like electric bill savings, but also for providing backup cooling. The benefits of this project should enable the design engineers working on mission critical applications (25% and growing) to provide more optimal cooling system designs. In addition, it will assist manufacturers of TES systems (and other systems) to understand the requirements for emergency cooling and adapt their products for these needs. It is expected that with the current trend 09/07 – 08/09 Washington State University Principal Investigator: Amir Jokar TC 8.5, Liquid to Refrigerant Heat Exchangers Research Strategic Plan Goals Supported: D1, D2 1394-RP Study of Carbon Dioxide Condensation in Chevron Angle Plate Geometry Exchanger In order to achieve this it is important to understand the heat transfer and mechanical integrity aspects of equipment that would be able to withstand high condensing pressures. Therefore, it is important to undertake a comprehensive study on the subject that would identify exchanger(s) with high mechanical integrity and enhanced heat transfer characteristics. This requirement could be fulfilled by undertaking an experimental program on a brazed plate or a shell and plate exchanger. These types of exchangers offer higher surface-areato-volume ratios along with enhanced heat transfer and high pressure ratings. It is apparent that a 1°F reduction in approach temperature on average results in 2–3% improvement in COP. Heat Gains from Electrical and Control Equipment in Industrial Plants, Part 2 The design of the air conditioning systems for an industrial facility including the electrical equipment room is normally performed in parallel with the facility electrical system design.This means that the cooling equipment is sized based on any available estimated heat rejection values or on rules of thumb, guesses and assumptions.Because the heat from the electrical equipment is often a significant percentage of the total cooling load, accuracy is important to a successful air conditioning system design.This is particularly true in mission critical facilities and electronic equipment areas. Appropriately sized systems are also important for energy conservation and moisture control. The scope of this work includes dc, medium, and low voltage switchgear motor, control centers, UPS systems, adjustable speed drives, panel boards, cables, and cable trays, and bus ways. Experimental Investigation of Hospital Operating Room (or) Air Distribution The proposed research will advance the state-of-the-art in design of these spaces; it may also promote advances in related fluid mechanics research areas. The most obvious advance will be in the enhancement of the design guidelines for hosp
