Heat PumpWater Source Heat PumpsWater source heat pumps (WSHP) provide hotor cool air to individual zones using water at aneutral temperature to transport heat. A reversiblerefrigeration cycle moves heat from the room into thewater to cool the room or vice versa.In many installations the water runs continuously,but the addition of an ON/OFF control valve reducespumping cost. Water flow is normally maintained ata constant level as long as the unit is operating. It iscritically important that the heat pump receives enoughwater to avoid freeze-up or refrigerant overpressureconditions. Insufficient water flow would also cause alow coefficient of performance (COP). Hence balancingworks extremely well with flow limiting AutoFlow .Balancing options:Rating1.
