Valve selection based on capacity calculation
As for extended capacity calculations and valve selection based on capacities and refrigerants, please refer to
Coolselector®2. Rated and extended capacities are calculated with the Coolselector®2 calculation engine to ARI
standards with the ASEREP equations based on laboratory measurements of selected valves.

Rated liquid and suction vapor capacity is based on:
• vaporating temperature t
e
= -10 °C
• liquid temperature ahead of valve t
l
= 25 °C
• pressure drop in valve ∆p = 0.15 bar
Rated hot gas capacity is based on:
Solenoid valve, Type EVR 2 - EVR 40
