1 Cond Unit for 4 indoor units

[carlfoster]

Hi all

We are currently designing an air con install where 34 units are required. As the cusstomer doesn't want 34 outdoor units littered about the place, we have decided the best solution is to use the Daikin Super Inverter condensing units.

Apparently, these can supply up to 4 indoor units and they have a controller to integrate the airhandling units, which we are manufacturing, with their condensing units.

Well theres the setup, now the question. We haven't worked with inverter technology before and we haven't fitted our units with heat pump technology either. We normally use TEV's as a metering device.

Any ideas on how would this affect the efficiency of the system if the inverter compressor were to "slow down"? Can TEV's work with this or are EEV's recommended?

Also, whats the best way to design the piping system for the heat pump to be used as TEV's only flow one direction?

Thanks in advance.
