correct layout of refrigeration piping in walk-in freezer
Good evening to everyone.
Most of the time I see that in walk-in freezers, the suction and liquid lines connected to the evaporator go immediately up and through the ceiling panel, exiting the walk-in as soon as possible. Is it correct to run the same lines across the walk-in and then though the wall panel? Does the low temp (-20F) may have some effect on the pipe insulation and/or the liquid refrigerant going through the liquid line?
Thank you for any responses.
