Cold-SNAP: the Newest and Coolest Technology in Refrigeration

This article was originally published on coolingpost.com on May 10, 2020. USA: A Harvard University team has developed an indirect evaporative cooling system which can cool air without adding humidity at a fraction of the energy cost of traditional cooling units.  Evaporative cooling is a well established technology which works well in a number of […]

Patent Seeks to Sustain Thermostatically Controlled Loads

This article was originally published on pnnl.gov, May 6, 2019. PNNL researchers Jianming Lian, Karanjit Kalsi, joint appointee Wei Zhang, and former PNNL intern Sen Li recently received a patent for a market mechanism consisting of novel bidding and clearing strategies. These strategies—for the first time—systematically incorporate the internal dynamics of thermostatically controlled loads, or […]

Molecular Pumps Could Be Long-Term Replacement for Age-old Mechanical Pumps

This article was originally written by Genoa Blankenship, pnnl.com, July 8, 2019 Greek mathematician and physicist Archimedes set off an historical evolution of the mechanical pump after he invented the screw pump around 200 BC. Despite the universal presence of the mechanical pump, a tool for moving gas or liquid, a replacement has long been […]

New Polariton Refrigeration Technique Provides New Way to Cool Electronic Devices

Polariton refrigerator could chill tiny semiconductor devices Physics World, May 15, 2015. Image credit: geralt A new method for using light to cool solids has been created by physicists in France and Germany. The technique uses quasiparticles called “polaritons” to remove vibrational heat from a tiny piece of semiconductor, and unlike previous optical cooling schemes […]
