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 an increase in the pressure of ammonia condensation by 0,1-0,3 MPa and to excessive energy consumption by 7%. The inerts removal using deaeration systems reduces energy consumption of the refrigeration installation, but at the same time some ammonia is lost. Various deaeration systems of ammonia refrigeration installations have been considered. It is shown that constant flowage of the condensers and receivers of the installation can be ensured with full return of ammonia in liquid form to the receiver.
