Refrigeration energy

The effects of trends toward lower efficiency and higher energy-consuming features and the countervailing force of policy inteiwentions is illustrated in Figurel, which displays the history of refrigerator energy consumption. 

The high internal heat load of many modern buildings means that comfort cooling may be needed even when the ambient is down to 10°C or lower. Under these conditions, a high proportion of outside air can remove building heat and save refrigeration energy. This presupposes that ...

ARS minimizes refrigeration energy by using distributed distillation and simultaneous heat and mass transfer in the dephlegmator (exclusive arrangement with Air Products) or HRS system. Two C2 streams of varying composition are produced. Hydrogen and methane are separated overhead. 

Several other methods involving cooling towers have been used to reduce refrigeration energy consumption. These systems, as applied to centrifugal and absorption refrigeration machines, are known as... 

When the RHE is switched, the air passages are rapidly depressurized and that air is lost. This can amount to 2% of the air o w and is an inefficiency of that design. The TSA system, however, needs regeneration energy and perhaps refrigeration energy.
