# Retrofits to handle increased throughputs

Standards require sizing the ME for minimum 110% or preferably 125% max compressor throughput

capacity to high MCE, even during higher throughput situations. ME are typically sized for cross sectional area to achieve a design velocity, according to SoudersBrown vapor load factor K, calculated as under: K=V /√((Y -Y )/Y ) where,

E.g. Room air conditioners draw air at 3 m/s velocity. What is the K factor for the mesh used in this application?

Putting value so fY =1000 kg/m 3 for water; Y=

K=3/((1000-1.293)/1.293)^0.5 = 0.11 m/s
