VAPOR LINE SIZING AND COOLING CAPACITY LOSS
PURON 1--STAGE AIR CONDITIONER APPLICATIONS
LONG LINE APPLICATION: An application is considered
”Long line” when the total equivalent tubing length exceeds 80 ft
or when there is more than 20 Ft vertical separation between
indoor and outdoor units. These applications require additional
accessories and system modifications for reliable system
operation. The maximum allowable total equivalent length is
250Ft. The maximum vertical separation is 200 Ft when outdoor
unit is above indoor unit, and up to 80 Ft when the outdoor unit
is below the indoor unit. Refer to Accessory Usage Guideline
below for required accessories. See Long--Line Application
Guideline for required piping and system modifications. Also,
refer to the table below for the acceptable vapor tube diameters
based on the total length to minimize the cooling capacity loss.
