Webdevelopment of better suction risers. In 1968, Marc Jacobs published the first, and still most influential, paper about oil return in suction risers. He simulated the suction line of a refrigeration system by injecting oil at the bottom of a vertical pipe with sight glasses to monitor flow regimes. WebSep 1, 2014 · Risers Risers are nothing but upward runs of piping that cause the refrigerant to flow upward. If there is oil mixed in with the refrigerant, it will have a tendency to fall back to the bottom of the riser because of the long climb to the top, fighting gravity all the way. This is why there should be a trap at the bottom of the riser.
