Refrigeration, HVAC and thermodynamics, starting with one question: why does it work that way?

We connect refrigerant properties, compressors, expansion valves, refrigeration cycles, COP and real equipment problems to basic physics and calculations. Beyond a simple yes or no, we examine the conditions that make an idea work—and its limits.

Shorts explore one question. Full lessons explain the principles, assumptions, calculations and evidence. Recent lessons include Korean, English and Japanese subtitles.
