WebJul 30, 2024 · Refrigeration is simply a mechanical means of artificially creating higher temperature differentials. Refrigerants change state from liquid to gas, and back to liquid, at temperatures standard for data centers. Water can absorb more than 3,500 times the heat of air, so it is often used as a secondary medium but does not readily change state. WebRefrigeration Cycle In this cycle, a volatile refrigerant fluid is pumped through the cooling coils of the evaporator to the indoor compartment of a refrigerator.
