<p>Alberto,</p>
<p> Both Types 136 and 954 are self contained devices (one indoor
unit paired with one outdoor unit) and as such can't easily be
combined together into a VRF system, which (at least in my limited
understanding) involves multiple indoor units all feeding to/from
a single outdoor unit. Some years back we worked on a research
project that inolved modeling VRF in Trnsys but I am not aware of
any commercially available VRF components at the moment. I would
be quite happy to hear about it if someone out there had
experience with one!</p>
<p>kind regards,</p>
<p> David</p>
