BS Box - 3 Pipe & 2 Pipe Systems.
Please excuse my ignorance.
But I have another few college / improver questions.
On a COOLING only system, I understand the 2 pipe principal - Suction/Discharge.
But on the 3 pipe heat pump system, I am getting slightly confused.
I felt 3 pipes on the return pipe run to the unit a Daikin VRV the other day, and am I right in saying that one is suction, one is hot gas and one is liquid ?.
Is this termed as MIXED phase ?.
On the 4 way reversing valve does it have input from the Hot Gas,Liquid and Suction as described above
In the ceiling voids I was told that there were BS boxes, can anyone explain the term BS,and how these actually work within the system please.
Thanks everyone for any help.
