MODIFIED FORMULAS COMPUTING THE VOLUME AND DIAMETER OF LOW-PRESSURE LIQUID RECEIVERS IN A AMMONIA REFRIGERATING SYSTEM
After surveying and testing a number of representative ammonia refrigerating systems for freezing foods processing in China and calculated with a proper mathematic models, a vapor separating velocity of 0.5～1.0m/s in low-pressure liquid receiver and liquid content of 20％ in the two-phase flow in vapor returning line are recommended to be adopted under the working conditions that the evaporating temperature is -10℃ -40℃ and the normal circulation ratio of ammonia pump is four times, with the max. limit of eight times. Diameter and volume of the low-pressure receivers could be reduced greatly (about by 50％)，by using the new calculation parameters. The refrigerating system will become more compact, which will save much investment in capital construction.
