DESIGN AND CONSTRUCTION OF A LOW CAPACITY PUMP-LESS ABSORPTION SYSTEM

Abstract

In this investigation, a low capacity absorption system has been designed nd constructed where the mechanical pump has been replaced with a ubble pump, reducing the cost and eliminating the electrical power. nitially, a test rig bubble pump has been built with a single Pyrex tube to est the effect of different parameters on pumping flow rate. An absorption efrigeration system with a capacity of 2.5 kW has been designed and onstructed. Results have shown that a bubble pump with five horizontal ubes with 2.5 mm diameter and submergence ratio of 0.4 has the best erformance for this low capacity absorption refrigeration system. The COP f this structure was about 0.51 and mathematical modeling shows that ncreasing the solution concentration at generator outlet decreases the COP f the system.
