Electrical Power Requirements for VRF Heat Pump

[bragase]

Hey guys! I am trying to find the power requirements for the Mitsubishi VRF Heat Pump systems, they don't specify how much kW but they have the MCA. Is it right it I calculate the kW based on the MCA they give me?

If that's all you have, then yes. But do you really want kW or kVA? You can't calculate kW without guessing on the Power Factor.

Yes it's kVA, my mistake.

That's the only info I have. Actually, that's the only info the manufacturer have in their spec sheet I don't understand why, specially in the bigger VRF units. Thanks for you reply!

kVA is kVA! That's all you need to size your power requirement! You size a supply equipment that is a bit bigger than the kVA needed by the VRF unit.
