Since 1972, Herrick Labs has hosted the premier international conferences on Compressor Engineering, Refrigeration, Air-Conditioning, and High Performance Buildings. 2022 marks the 50th anniversary of the very first Herrick Conference hosted at Purdue University. More than 800 industry experts from 30 countries come to Purdue to present cutting-edge research, exchange ideas, do some personal networking, and tour the amazing facilities of Herrick Labs.

Why Attend?

  • Excellent opportunity for practitioners and researchers in industry, government, consulting offices, laboratories and universities to reach an audience of 800 participants from over 30 countries

  • Ideal location for presenting compressor, refrigeration/AC and high performance building systems research results and state-of-the art technology

  • Receive CEUs (continuing education units) where applicable

  • Discuss challenges and potential solutions on important issues of compressor technology, new refrigerants and refrigeration technology and efficiency, as well as energy-efficient building technologies

  • Invited keynote speakers addressing current, world-wide issues of interest facing society today

  • Panel discussions highlighting the latest breakthroughs in technology, alternative technologies in research and industry

  • Opportunity to network with attendees and officers from industry organizations

  • Registration includes three parallel conferences, reception, luncheon, and dinner


Compressor 104 – Numerical and Experimental Techniques Applied to Noise and Vibration in Positive Displacement Compressors

Coordinated by: Eckhard A. Groll (Purdue University), Davide Ziviani (Purdue University), Haotian Liu (Purdue University)

In this fourth edition of the Compressor Short Course, the fundamentals and the practical aspects of noise and vibration phenomena in positive displacement compressors will be covered. It is well known that compressor performance heavily relies on each single component and its unique interaction inside the compressor housing, and subsequently requires a thorough understanding of the composite system to resolve issues arising from noise and vibration. Each positive displacement compressor type is characterized by different compression mechanisms and fluid-structure interactions. During the course, lectures will focus on the main noise and vibration sources of each compressor type and provide numerical and experimental methodologies to identify and mitigate such effects. The short-course consists of eight 45-minute lectures and will provide ample time for hands-on experience and discussion.

Refrigeration Short Course 1 – Ejector Design for Vapor Compression Systems (morning session)

Coordinated by: Prof. William Murphy (retired University of Kentucky) and the U.S. National Committee of the IIR in collaboration with Herrick Laboratories Faculty

Ejectors are being developed as a way to improve vapor compression cycle efficiency by replacing the isenthalpic expansion process. Ejectors have no moving parts, like expander work recovery devices, so they have the potential to produce simpler and lower cost designs with improved system reliability.

Refrigeration Short Course 2 – Update on Flammable Refrigerants (afternoon session)

Coordinated by: Prof. William Murphy (retired University of Kentucky) and the U.S. National Committee of the IIR in collaboration with Herrick Laboratories Faculty

The demand for refrigerants with lower GWPs has led to a class of refrigerants that are considered mildly flammable. The use of flammable refrigerants will require changes in various safety codes and guidelines related to building design, installation and service requirements, and system design.


The conference organizing committee is pleased to invite students to submit abstracts for the 2022 Student Best Paper Award Competition. Please note the following updated eligibility information and other guidelines for the competition:

  • Students at the undergraduate level and graduate level at the time of the paper submission are eligible to compete

  • Students must be the first author on the submitted papers and must present their work at the conferences to compete

  • Every student paper submission to the 2022 Student Best Paper Award Competition must be accompanied by a separate nomination statement by the advising professor

  • Every advising professor may nominate a maximum of two student paper submissions to the 2022 Student Best Paper Award Competition

  • Cash prizes for each conference will be presented to the top three papers in the amounts of $1000, $500 & $250
