YAMAGISHI, Y. (2026). The Ceiling of a Heat-Driven Refrigerator Is the Product of an Engine's Efficiency and a Refrigerator's Coefficient of Performance ── when cooling is driven by heat alone, as in the absorption refrigerator of Einstein and Szilard, the ceiling of heat removed from the cabinet per unit of heating is 0.200992 × 10.926000 = 2.196034 for heating at 100 ℃, ambient 25 ℃ and cabinet 0 ℃, and in the entropy ledger it is a ratio of drops in inverse temperature; putting in no work is not free, since the work carried by the heating is paid ── the separator is whether what is put in is work or heat with a temperature difference ── [Paper 1025]. https://doi.org/10.5281/zenodo.22860111
