Geothermal - Earth Loop Condensor

Researching the use of an earth loop system because I understand it will reduce cost/energy kWh to cool the home compared with conventional air con units ( air condensors ) .

However, not yet sure the best way to integrate this into the home.

i) duct work in each room fed from a central evaporator and compressor

ii) evaporator units in each room connected to a central compressor
