What is an oil lift?
A) An oil lift helps return oil up a vertical riser using an integral orifice tube, which creates a Bernoulli effect, forcing oil up the line. B) An oil lift is an electric oil pump that moves collected refrigerant oil up against gravity. C) An oil lift is a trap at the bottom of a vertical suction riser. D) An oil lift is the increase in pressure created in the suction line due to the presence of refrigerant oil.
