15 Loop W ater Applications It should be noted that there is no me- chanical differen ce between geother- mal (closed loop) and ground water (open loop) GSSD units. General ly in a closed loop application, there is a percentage of antifreeze in the water.
16 GSSD Units Coupled with TWE Air Handlers The GSSD IS coupled with the TWE- E series. Table 4 may be used to det er- mine the amount of charge necessary for the split unit system withou t any refrigerant line connecting the two. Table 5 can be used to determine the amount of refrigerant needed for lines.
17 Refrigeration System ! Compr essor: The unit includes a high efficiency scroll compressor with and internal v ibration isolator that absorbs start ing and stopping energy .
