Chinese say, better heat transfer is "groovy"
Use of smaller-diameter copper tubes in evaporator and condenser coils is leading to more efficient Chinese refrigeration products....
Super-efficient heat exchanger could be a g
Heat exchangers based on vortex flow could work well enough to eliminate the serpentine-tube style heat exchangers common to refrigerators and chillers....
Efficient heating and cooling for EVs
The PNNL says adsorption heating and cooling could be an efficient means of keeping EV riders at a comfortable temperature....
More efficient grocery store coolers
Better physics could bring commercial coolers operating at much higher energy efficiency....
The energy efficient machine tool
When the topic of energy efficiency comes up, energy-efficient machine tools don't typically spring to mind. Yet machine tools contain motors and auxiliary...
