RESUMO

Was projected and constructed one diaphragm pump for one system of refrigeration for water-ammonia absorption that operates using expanded vapor it enters the same levels of pump action pressure. Through an experimental group of benches, the conditions of functioning of the pump had been verified that simulates a system of absorption in the suction phases and stresses of the solution water-ammonia of the absorber for the generator through an leveI of low pressure for an high-pressure leveI. In the test one container was used contains water subject to lowers pressure in the reservoir representing the absorber, an air-tight cylinder the high pressure with entrances and necessary exits for the water and air scoop representing the generator, an air compressor for pressurization of the system and devices of control and command for the a automation of the system. The viability of operation of the equipment was demonstrated as also the joined limitations of the archetype
