The use of refrigerant mixtures in refrigeration machines has been proposed in the technical literature. Some but not all of the arguments for and against the use of mixtures as refrigerants are examined in this study. An issue associated with use of blends is the segregation on leakage and the ensuing loss in capacity and performance change on repeated recharging with the original mixture. We ...

Climate change is exacerbating water shortages in upstream basins the Korean peninsula that lack agricultural supply systems. The basin investigated this study requires an extra 208 m3·d?1 of during May (the busiest month for agriculture). purpose was to assess a hybrid-artificial recharge and circulation system, which composed hybrid-recharge source re-infiltration pumped field, estimate yield...
