4 Way Valve Water inlet Water-to-refrigerant heat exchanger Water outlet Compressor Finned-tube heat exchanger Expansion device Introduction: What is Water Source Heat Pump?
Water Source System Categories 1. Water Loop Heat Pump System 2. Ground Water Heat Pump System 3. Surface Water Heat Pump System 4. Ground Coupled Heat Pump System
Water Source System Categories Water Loop Heat Pump • Most common configuration • Re-circulating water loop • Cooling tower & boiler
Water Source System Categories Ground Water Heat Pump • Ground water from well • Drained back to well, drain, stream or lake • Stable throughout the year • Limited by availability of water table and aquifers in the ground
Water Source System Categories Surface Water Heat Pump • Open or close loop • Open – water being returned back to source or drain • Closed – water being re-circulated in the closed loop • Stable throughout the year
Water Source System Categories Ground Coupled Water Heat Pump • HE is buried into the earth • Installation cost is high • Massive & stable thermal capacity
