Energy saving technologies in ammonia refrigeration applications using well designed pump circulation systems.

Author(s) : PARANJPEY R.

Summary

This paper presents a case study of refrigeration plant designed for a customer in India, using liquid ammonia pump circulation system. At the time of designing and selecting the equipment for this particular project the author had to struggle to get satisfactory design guidelines. The detailed information is not readily available on whether to use hand expansion valves or flow control valves, what is the ideal pump discharge pressure, what should be the temperature difference between inlet and outlet of evaporator, how to adjust optimum flow etc and it forms part of the system design. This paper is presented with a view, to give some readily available guidelines for the people who wish to design efficient pump recirculation systems.This paper is based on the design of actual system already commissioned and working satisfactorily for last 4 years.
