Dear Friends,

At split unit system while orifice as expansion valve is on outdoor unit, When you want install it, for example you see there are 5m copper pipes for installing.

I had discussion with one of my friends :

1 – He told me this 5m is accidentally and we can increase this length as long as we want.

2 – I told him 5m copper pipe has plan behind. The initial diameter of orifice was calculated. When liquid line exits form condenser and pass form that orifice, Frigidity will starts 5m further by this reason company has put 5m copper pipe for jointing condenser to evaporator.

If it is possible please share your knowledge with me.

Sincerely yours.
