2 DX FCU from 1 ACCU

[PacificSteve]

Anyone have experience with serving multiple DX FCU with one ACCU? This is for cooling of 2 offices and 1 conference room. The conference room has limited hours of operation, and not at same time as offices in general, therefore, it would get its own mini-split system. The 2 offices are on either side of the conference room. Time of use of offices are not necessarily the same, nor is the load.

Should I bite the cost bullet and just get 3 mini split, or is it likely that the 2 offices can be served well by one ACCU? Distance between office FCUs would be about 30 feet.

Thanks in advance.

In the long run you will be better off with a seperate system for conference room.

I've been to many meetings where the make shift system did not work

 

I have a reasonable amount of experience in the use of VRF/VRV systems, that use multiple "internal" units connecting to DX 1 external unit, and have found their performance in rooms with differing environmental conditions to be exceptionally good.

In meeting rooms and others with high occupancy, care must be taken in the selection of the system size in order to cater for heating/cooling the incoming fresh air, which may or may not be centrally treated.

Mitsubishi and Sanyo have each a system that uses one condensing unit and multiple evaporators. I think they also have a heat pump application where some zones can be on heating while others are in cooling mode. Contact your local supplier.
