Looking for some information on the Star LPR system and perhaps a good piping diagram I understand the concept of using the wet suction return in the LPR to subcool the condensed liquid in the coil mounted in the vessel. However I don't understand what type and the location of the "metering device" to drop from high pressure to low pressure and what balances the flow of liquid to each evap. How many evaps can be installed on a single LPR system and can this application also be applied to halocarbons as well as NH3? Thanks for the input
