Dear building-sim,

We are considering providing service hot water and cooling requirements for
apartments in a residential tower via small water source heat pumps in each
apartment. Heat rejection would be provided by infrastructure comprising of
a cooling tower and possibly some thermal storage.

One appeal of this would be billing. There wouldn't need to be seperate
billing for cooling, shw and electric. But usage would still be linked to
cost. It would also make things look a lot cleaner (no "window shakers"!).

Does anybody on this list know of any examples of water source heat pump
products that might suit this purpose? Water to water (serving fan coil
terminals in the apartment) or water to air might be considered.

Best regards

Chris Yates
