How are plate heat exchangers used in an ammonia
refrigeration system?
Answer Posted / suresh
Plate heat exchangers are pretty widely used In ammonia
refrigeration systems, and they can be much smaller than the
equivalent tubular exchanger. They work best flooded. A
flooded exchanger system needs a way to separate the liquid
from the vapor. A typical system has a vessel which acts as
knockout drum, accumulator and header tank in one, along
with the heat exchanger. Liquid ammonia flows from the
vessel to the exchanger, and liquid/vapor is returned to the
middle of the drum. Vapor is removed from the top of the
drum. The liquid/vapor mixture from the exchanger has a
lower density than the liquid entering the exchanger, so
gravity provides the driving force to circulate the refrigerant.
