After some initial research I've decided the System i'm going to use in my project is a Passive system with heat exchanges submersed in the effluent outflow. these will be hooked to a three way valve to control the flow through the heat exchanger to maintain a constant temperature in the loop. The pumps will circulate fluid through the district energy system. My reasoning for going with this system is that the cost of this system is far lower than an active heat recovery with a heat pump. This allows the system to be feasible for smaller communities, There is also less maintenance for this system allowing for deployment in more remote communities.
To get this information i used information and costing from various manufacturers as well as RS Means mechanical Cost Data.

It would be very helpful if you could post some pictures of what your design is going to be. I don't have much knowledge in energy systems. I must say it does sound like a very unique idea to recover heat to use elsewhere.
ReplyDeletei intend to have a schematic of the design with a flow diagram later today so check again tonight and it should be up.
