UNIT ASSEMBLY CONNECTIONS FOR TWO-PIECE SHIPMENTS

Units shipped in two pieces are charged with nitrogen at a pressure of approximately 2 psig. This charge should be retained until the unit piping is to be completed, at which time nitrogen pressure will be relieved. The nitrogen is relieved from the bottom shell through one of the charging/sample…

INSTALLING THE ABSOLUTE PRESSURE GAUGE

UNIT WATER PIPING The absolute pressure gauge is shipped separately for field installation. Mount the gauge on the gauge bracket which is located on the lower shell of the unit adjacent to the purge piping. Use #10-24 UNC x 1 inch long flat head machine screws and #10-24 UNC hex nuts. Make sure the…

tion unit should be taken off the main steam supply line

from the top side to minimize the possibility of condensate carry-over. Additional consideration should be given to steam flow velocity, especially in those applications where noise is a factor. Generally speaking, steam velocities up to 6,000 fpm (30 m/s) will not produce an objectionable noise…

STEAM CONDENSATE RETURN SYSTEM

Steam condensate return systems should be designed in accordance with good engineering practice for the general purpose of removing condensate from the absorption unit’s generator and returning it to the boiler. Either an atmospheric or a vacuum condensate return system may be used with absorption…

Vacuum Breaker (if desired) – A vacuum breaker

will often not be necessary, but one can prevent condensate build up in the generator bundle of the chiller at part loads. If an atmospheric return system is used the generator will not operate in the vacuum region, but will operate at atmospheric pressure even at low load conditions. Throttling of…

coolant must be provided to cool the maximum condensate flow to the desired temperature. Coolers may be air or evaporatively cooled, providing they can produce the desired leaving condensate temperature. Coolant flow could be manually set for maximum load and allowed to operate continuously at that…
