Suction heat exchanger de-misting function

A HVACR system, comprising:

• a compressor;
• a condenser;
• a first expander;
• and a first liquid-vapor separator in fluid communication, wherein the first liquid-vapor separator includes:
• a first housing,
• a first inlet disposed on the first housing and configured to receive a working fluid,
• a first vapor stream outlet disposed on the first housing and configured to release a first vapor stream of the working fluid to the compressor, and
• a first demister disposed in the first housing and configured to transfer thermal energy between the working fluid and the first vapor stream, such that at least a portion of the first plurality of entrained droplets absorb thermal energy from the working fluid to evaporate said portion of the first plurality of the entrained droplets when the first vapor stream flows through the first demister.

A method of demisting entrained droplets, comprising:

• flowing a working fluid into a liquid-vapor separator, the liquid-vapor separator including a headspace, a heat exchange section, and a demister;
• evaporating the working fluid by way of the heat exchange section to obtain a vapor stream of the working fluid, the vapor stream including entrained droplets;
• and
• flowing the vapor stream through a demister;
• wherein the vapor stream absorbs heat at the demister such that at least a portion of the entrained droplets are evaporated.
