| 摘要 |
The invention relates to refrigeration engineering, in particular to apparatuses for removal of gases that are not condensed, and their removal from systems of cooling installations - air separators. The appliance has plate heat exchanger connected to separator that is equipped with coil, level controller, indicator of partial pressure of ammonia, relay of pressure difference, supply and discharge pipelines on which solenoid valves are installed and control valve. The coil is installed in vapor zone of separator over upper level of liquid ammonia. The invention provides more complete removal of air from ammonia refrigeration unit, decreases losses of cooling agent and its penetration to environment at separation of gases that are not condensed from the system.
