Two cu pipes into one insulation is usually at the FCU. Thereafter is usually one to one unless the trunking is too small to accommodate then they will squeeze 2 into 1.

My office partitions are too narrow. Hence no choice, 2 into 1.
I'm afraid it may lead to condensation as I understand that one of the copper pipes is warmer and one is colder..
