Global Education And Professional Development Of Minority Youth, Jennifer Sdunzik, Rocio Leon, Annagul Yaryyeva

Engagement & Service-Learning Summit

“Global Education and Professional Development of Minority Youth" was developed to establish connections between the Purdue student body and the Frankfort community. By engaging high school students in workshops that focus on identities, students are encouraged to identify and market the talents they contribute to an increasingly globalized world. Students participate in workshops to develop their professional skills and articulate their transnational social location. The workshops were designed to empower our participants to embrace their sense of social value and responsibility in their communities with the perspective of a global citizen.

Purdue’S Biowall, Purdue Ect Team

ECT Fact Sheets Archive

Mechanical ventilation, energy recovery ventilation, and infiltration (air that leaks into a building) are commonly used to introduce fresh air. These are all valid approaches, but a living plant-based filter is an innovative complement to these traditional technologies. A Biowall has the potential to improve indoor air quality while reducing the quantity of air needed for ventilation, creating the potential for energy savings. Figure 1 shows a Biowall prototype being evaluated in the ReNEWW House, a research home located near the Purdue University campus (http://www.renewwhouse.com/).

Numerical Simulation Of Pump Oil For Rotary Compressor Under Different Crankshaft Structures, Wang Yanzhen, Chunhui Liu

International Compressor Engineering Conference

The oil lubrication system of the crankshaft pump is an essential part of the rotary compressor. In the crankshaft pump oil lubrication system, the crankshaft has two kinds of inner hole structure: straight through hole and horizontal hole. The direct through hole and the transverse hole are different not only in the processing mode and cost, but also on the oil quantity of the pump. In this paper, based on the CFD software the fluid field of whole compressor exhaust chamber under different speed is simulated, and the pressure pulsation curves of crankshaft through hole end and horizontal hole end …

An Integrated Assessment Of The Potential Impacts Of Climate Change On Indiana Forests, Richard Phillips, Leslie Brandt, P. David Polly, Patrick A. Zollner, Michael Saunders, Keith Clay, Louis Iverson, Songlin Fei

Forest Publications

Forests provide myriad ecosystem services, many of which are vital to local and regional economies. Consequently, there is a need to better understand how predicted changes in climate will impact forests dynamics and the implications of such changes for society as a whole. Here we focus on the impacts of climate change on Indiana forests, which are representative of many secondary growth broadleaved forests in the greater Midwest region in terms of their land use history and current composition. We find that predicted changes in climate for the state – warmer and wetter winters/springs and hotter and potentially drier summers …

Development Of A Compact Absorption Chiller Using Hydrophobic Flat Sheet Membrane, Shunnosuke Inoue, Chaobin Dang, Eiji Hihara

International Refrigeration and Air Conditioning Conference

Automotive absorption refrigeration system has enormous potential to conserve energy using the exhaust gas from the car engine. The absorption system, however, has not yet been attracted to automobile application owing to its large volume, weight, and weakness for unexpected vibration and the slop while driving. By the vibration, the LiBr solution is scattered not on the cooling tube in the absorber, that is leading to mal-function of absorber. Also by sloping road, the free surface of solution in the generator and absorber causes mixing of the refrigerant and LiBr solution. To solve the problems, we used hydrophobic flat sheet …

Tomato Cultivar Evaluation In High Tunnels, Northern Indiana, 2017, Elizabeth Maynard, Erin A. Bluhm

The adoption and proliferation of variable speed compressors and electronic expansion valves (EXVs) in high-efficiency reversible chiller systems provides the opportunity to optimize the performance of the unit around a new set of variables. This paper details the benefits of a controls framework designed to enable low-superheat (below 5K) operation to optimize the seasonal energy efficiency ratio (SEER) of a commercial-scale chiller in a safe manner. The various attributes of low-superheat operation over conventional (>5K) chiller operation, including the reliability impact on the controller and compressor, is discussed. The performance benefit for a range of capacities and compressor configurations, …

Model-Free Control And Automatic Staging Of Variable Refrigerant Flow System With Multiple Outdoor Units, Liujia Dong, Yaoyu Li, Tim Salsbury, John M. House

International Refrigeration and Air Conditioning Conference

For efficient operation of a variable refrigerant flow (VRF) air conditioning system with multiple outdoor units (ODUs), we propose a model-free control strategy based on extremum seeking control along with automatic staging control logic. The proposed strategy is evaluated with a representative VRF system consisting of 12 indoor units (IDUs) and three ODUs. The IDU zone temperature is regulated by EEV opening, and the compressor pressure is regulated by compressor speed. To optimize load sharing among multiple ODUs in operation, a set of bypass valves (BPVs) are added to the suction side of the compressors to manipulate refrigerant flow distribution …

Three-Fluid Heat Exchanger As Evaporator In Multi-Source Heat Pumps With Viable Options For Alternative Defrosting Methods, Thore Oltersdorf, Gerhard Schmitz, Hans-Martin Henning

International Refrigeration and Air Conditioning Conference

Three-fluid evaporators can be used for multi-source heat pumps to keep refrigeration circuits simple in design since it avoids the usage of a second or more evaporators. In this work a defrosting control design is presented with a lowered electrical energy demand compared to the standard procedure of reverse flow defrosting with 4-way-valves. Objective of this new defrosting concept is to develop a fully autonomous defrosting strategy. The two heat sources allow direct thermal communication of an air source and a second heat source based on a hydronic circuit with the evaporating refrigerant. The proposed defrosting strategy is based on …
