Multiple DX coils for single condenser
Multiple DX coils for single condenser
(OP)
Is it possible to serve several DX coils using one air-cooled condenser and if possible, what is the control strategy that I should use? Also, is there reference material (abstracts, etc) that I could access to help me with this problem?
Thanks for you help,

But there are many ways to control a multiple evaporator systems. You will need to be more specific about your application for me to suggest a control scheme.

First, sorry about my poor english.
Cooky is correct as usual. As a HITACHI application engineer in Brasil, I must include HITACHI SET FREE System in the wall. see the site: http://www.hitachiaircon.com/hac/en/range.jsp?range_ref=2
For a very simple explanation, the condenser unit works with INVERTER DRIVEN scroll compressor, that controls the service frequency, so, quantity of refrigerant that goes up to the coils (evaporators). Every coil has an electronic expansion valve (EXV), in time, controls (PID) individually each coil cooling/heating capacity by a temperature set/measure of each zone.
Stay Cool...
