LIQUID REFRIGERANT RECIRCULATING UNITS The benefits of continually overfeeding the evaporators of a multi-circuited refrigeration system are recognized worldwide by industrial users of ammonia refrigeration. Pumped liquid ammonia is the prefered method of evaporator feed because of its simplicity and high performance. By completely wetting the inner surface of the evaporator coils with an excessive flow of subcooled liquid refrigerant, maximum heat transfer rates are achieved, resulting in higher system efficiency and reduced operating cost. Overfeeding, especially in long coils, not only assures wetted surfaces fron one end of the coil to the other, but also tends to sweep gas bubbles out of the evaporator at an accelerated pace. |
The formation of flash gas, caused by the change from high pressure to low pressure conditions, takes place in the low pressure receiver rather than in the evaporator Horizontal recirculators refrigeration capacity ranges from 19 TR @ -10 def F - to - 1404 TR @ 50 deg F for single stage systems (based on 185 psig condensing) Vertical recirculators refrigeration capacity ranges from 75 TR @ -10 def F - to - 2,607 TR @ 50 deg F for single stage systems (based on 185 psig condensing) |
