Hi all,
I would like to talk about concept of refrigerant piping..Lets talk about VRV/F. We have, for instance one compressor(condensing unit) and multiple evaporators. Now, when you would use the the headers and when T joints? And what is an advantage and what is a disadvantage? I have talked with guys from Daikin and they told me that they are avoiding Headers but without any explanation....
