Abstract

The performance of the ammonia refrigeration installation is influenced by the presence of inerts — non-condensable gases that are accumulated in the condenser and the receiver. The increase in the gases concentration leads to a decrease in the heat transfer coefficient of the condenser by 3...5 times, an increase in the pressure of ammonia condensation by 1...3 bars and to excessive energy consumption by 7%. The inerts removal reduces power consumption of the refrigeration installation, but some ammonia is lost. Various systems of non-condensable gases removal, the places of their accumulation and the installation of the blow-off valves are considered. The examples of connecting automatic inerts eliminators are presented. The reasonability of a multipoint automatic removal of the inerts has been pointed out.
