If you have ever installed a split DX unit, then you must have calculated the size of the refrigerant lines between the condensing unit and the fan coil unit. If you oversize the line, your cost will be unnecessarily high but more importantly, you may find that the velocity is too low to return oil to the compressor. Features:
Quick refrigerant line size calculations.
Based on method used in ASHRAE Refrigeration Handbook.
Allows manual override to alternate selections.
Large refrigerant database, including R134a, 407c and 410a.
Generate customizable reports.
Uses actual condensing and evaporating temperatures.
Shows velocity, pressure drop and resultant saturated temperature drop.
Allows you to specify temperature drop limits.
Allows you to override calculations and see the consequence.
Includes metric and imperial units.
