On any type of refrigeration system, from small reach-in coolers all the way to large chillers, controlling the head pressure of the refrigerant is important. That’s because it helps keep the system ...

When performing a preflight, it is important to review the temperature compensation chart next to the oxygen cylinder to make certain you have a full supply of oxygen when needed. Temperature has a ...

For the first time in the world, researchers (From Korea University, Sukbae Lee, Ji-Hoon Kim, Hyun-Tak Kim) have succeeded in synthesizing a room-temperature superconductor (Tc≥400 K, 127∘C) working ...

CO 2 refrigeration (R-744) systems operate at significantly higher pressures compared to legacy hydrofluorocarbon (HFC) systems. For example, on hot summer days, between its medium-temperature ...

AbstractBergmann’s rule—an increase in body size with latitude—correlates with latitudinal declines in ambient temperature and predation risk, but relatively few studies simultaneously explore the ...
