Heat Pumps for Heating and Cooling Comparison of parallel and series installations for ground loops System Configuration Advantages Disadvantages Parallel Installation Smaller pipe size. Less antifreeze required. Balanced flow distribution. Reduced pressure drop along shorter flow paths results in smaller pump power requirements. Header lines require more complex pipe joining operations. Special care needed to ensure complete air removal from all flow paths when purging system at start up. Series Installation Ease of removing trapped air. Simplified flow path. Single pipe diameter entails simpler pipe fusion joints, enabling quicker installation. Single flow path enables purging to remove air from the loop when filling with water or antifreeze solution. Longer flow path requires larger diameter pipe to minimize pressure drop. Requires a larger pump power. Requires greater antifreeze volumes. System capacity limited by total pressure drop from end to end, so not suitable for large building applications. 3.8. • • Earth Loop Piping The most commonly used earth loop piping material is high density polyethylene (HDPE). More specifically, this piping is designated as PE3608 based on the ASTM F-412 standard. HDPE is a thermoplastic meaning that it can be repeatedly melted and reformed. It is easily connected using fusion techniques which ensure a leak- free joint. 39PDF Image | Heat Pumps for Heating and Cooling
