ADVANCE Distinguished Lecture Series presents Eckhard Groll
Eckhard Groll, professor of mechanical engineering at Purdue University, will present "Novel Compression Concepts for Heat Pumping, Air Conditioning and Refrigeration Applications" at 10:30 a.m. Wednesday, Sept. 30, inmechanical and nuclear engineering Senior Design Room, 3034 Rathbone Hall.
Groll's lecture is part of the ADVANCE Distinguished Lecture Series and Melanie Derby, assistant professor of mechanical and nuclear engineering, is Groll's host.
The lecture abstract:
The phase-out of CFC and HCFC refrigerants, combined with advances in 1xbet online casino technology, such as reduced noise and vibration and mechanical capacity control, has motivated the development of novel compression concepts for the vapor compression cycle. This presentation provides an overview of several new 1xbet online casino developments for refrigeration, air-conditioning and heat pumping applications, including three novel compressors called the rotating spool 1xbet online casino , bowtie 1xbet online casino and Z-1xbet online casino . The rotating spool 1xbet online casino provides reduced friction and low manufacturing cost compared rolling piston compressors. The bowtie 1xbet online casino offers an integrated method of capacity modulation for use in domestic refrigerators/freezers. It modulates the cooling capacity by changing the piston stroke without changes of the clearance volume for better thermodynamic efficiency. The 1xbet online casino is called bowtie 1xbet online casino due to its two sector-shaped, opposing compression chambers forming a bowtie. The Z-1xbet online casino is a dual-chamber hermetic rotary 1xbet online casino with opposing upper and lower compression chambers separated by Z-shaped blade. The 1xbet online casino offers significantly lower noise and vibration levels than a conventional rolling piston 1xbet online casino . In addition to presenting these new 1xbet online casino types, research on liquid-flooded compression and refrigerant vapor-injected compression will also be presented. Both of these compression technologies have the potential to significantly increase the operating range of compressors and improve vapor compression system performance.
