My raw water pump flows into a manifold with valves and feeds three air conditioners / heat pumps. I reworked the plumbing during my refit, and it does work, but water flow is maybe marginal. Replaced the raw water pump for my charter boat today with a higher flow pump. The increased flow has the heat exchanger running cooler and the AC output temperature running lower ( colder air coming out the vents). I'm considering running the 3 heat pump raw water systems in series as opposed parallel as they are now. Conceptually, one heat pump should function better with higher water flow. I'm sure 2 units running in series would benefit also. With 3 units running, I feel confident there is still plenty of room for all the BTUs from all three units. As luck would have it, the highest duty cycle unit would be first and the lowest would be last.
Looking for thoughts and potifications from the peanut gallery. Does anybody have a system with the units in series? Can anyone point to a document that explains the theoretical advantages of one system over the other.
