Upward displacement of air is the displacement of air in the upward direction as the gases are collected by downward delivery.
Since pure and dry chlorine gas is heavier than air, it should be collected by upward displacement of air.
The principle here is that if a gas is denser than air, it is often more convenient to collect it in a gas jar or test tube by downward delivery. The gas produced in a chemical reaction is passed through a delivery tube into the gas jar, where it sinks and pushes the air out of the top.
