Abstract
Embodiments provided herein are directed to systems and methods of re-injecting vaporized flash refrigerant from an economizer into a two-stage compressor. The injection can be through an injection port positioned after the first compression stage. The location of the injection may have a relatively low static refrigerant pressure. The injection port and/or an injection pipe of the economizer may be configured to pre-condition the vaporized flash refrigerant so that a flow velocity and/or direction of the vaporized flash refrigerant flow can be match a flow velocity and/or direction of the refrigerant in the refrigerant conduit.
