Electrical requirements for Heat Pump vs FCU.
« on: November 30, 2015, 10:41:49 AM »
Can anyone tell me what the difference would be in terms of the electrical requirements if a condo building was fitted with either Heat Pumps, 2 Pipe FCUs or 4 Pipe FCUs? I.e would the building, overall, require higher or lower loading for the various systems? I can't seem to find answers anywhere.

Thanks in advance...

What is the source of heat if using the FCU?

If you use a heat pump are they being connected to an FSU or is the heat pump unit an all in one unit installed inside the exterior wall?

Assuming the FSU was getting heat from a water heater, is the water heater electric or gas?

Thanks for the reply.

For discussions sake, say the system options (for the same building) are are as follows:

HP:
700 Ton Cooling tower, Gas Boilers providing 17,100 MBH and HPs are getting heat from water.

2 Pipe FCU:
600 ton cooling tower, 600 ton chiller, Gas Boilers providing 17,100 MBH

4 Pipe FCU:
600 ton cooling tower, 600 ton chiller, Gas Boilers providing 17,100 MBH

What impact would the different systems have on the overall electrical loading of the building?
