Main Presentation - 7:10 pm - Daniel J. Dettmers, Satisfying the Curling Divas Demand for Perfect Ice

 Main Presentation Highlights:

Curlers are divas.  I know this because I am one…a curler that is.  Curling, a sport whose popularity cycles with the Olympic Games, is often described as chess on ice with the execution of shuffleboard.  It’s a game for detail oriented individuals that enjoy the cold.  Any slight variation from “perfect ice” is often met with calls for the ice maker’s head.  Unfortunately, state of the art in shaping curling ice lies more in the realm of “art” than “science”.

Icemakers spend countless hours perfecting their own formula of scraping, nipping, water temperature, and pebble size.  While these all matter, the biggest factor they often neglect is the condition of the air above the ice.  It can be responsible for sublimation, condensation and…the greatest nemesis of the curler…frost.

 In this session, we will discuss methods and technology that cash strapped curling clubs can use to control frost on the ice and improve game condition ice.

Dan has been working in the industrial refrigeration field for nearly 2 decades with occasional forays into commercial and residential HVAC.  His interests and expertise lie in a number of areas related to industrial (ammonia) refrigeration systems, refrigerated structures and mechanical integrity, OSHA PSM compliance and beyond.  Related areas of interest include food processing, food preservation, energy use reduction and refrigerant selection.  Dan also provides seminar training and technical presentations to a variety of audiences. Dan received his Bachelors in Nuclear Engineering and his Masters in Mechanical Engineering both from U.W Madison.

 As a member of ASHRAE, Dan has chaired the Refrigeration Committee, Program Committee and the 2014 Refrigeration Handbook Committee as well as served on numerous other standing committees.  Among ASHRAE’s Technical Committees, Dan has chaired the Refrigerated Warehouse (twice), Refrigerated Applications and Custom Engineered Refrigeration Systems committees.  Dan has also assisted in the development of ASHRAE’s Position Documents, Ozone Depleting Substances and Refrigerants.

 For fun, Dan has been known to through a few stones and kick back a couple of cold ones at the Madison Curling Club.  Dan has been a curler for over a decade and influential in the facility’s refrigeration and mechanical systems for the last 6 years.
