1. A hybrid cooling system for a datacenter, comprising:
a chiller plant to provide supply of coolant;
an air-cooling unit (ACU) configured to be disposed in a data hall of the datacenter;
a coolant distribution line comprising a first portion, a second portion, and a third portion, wherein the first, second, and third portions are in series fluid communication and the ACU receives supply of the coolant from the chiller plant via the first portion;
a coolant distribution unit (CDU) coupled to an electronic component in the data hall, wherein the ACU and the CDU are in series fluid communication via the second portion of the coolant distribution line and the coolant egressing the ACU passes through the second portion to be fed to the CDU; and
a heat exchanger in series fluid communication with the CDU via the third portion of the coolant distribution line, wherein the coolant egressing the CDU passes through the third portion to the heat exchanger.
