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 ...

When refrigeration systems are exposed to low outside air temperatures, the condensing pressure will fall, and if the head pressure gets too low, the metering device will not have enough pressure drop ...

One of the great inventions of our time — in terms of its social impact and influence on the health care and food preservation industries — refrigeration equipment is everywhere, from hotels, ...
