1. A method of cooling a refrigerant, comprising:
providing a condenser comprising a condenser shell that contains a condenser chamber, a condensing conduit, and a cooling conduit;
condensing a refrigerant within the condenser chamber from a vapour phase to a liquid phase by exchanging heat from the refrigerant in the condenser chamber to a fluid in the condensing conduit;
supplying a first portion of the condensed refrigerant from an outlet of the condenser chamber to the cooling conduit via a first expansion valve such that the first portion of the refrigerant decreases in pressure and temperature before entering the cooling conduit; and
cooling the refrigerant in the condenser chamber upstream from said outlet by exchanging heat from the refrigerant in the condenser chamber to the first portion of the refrigerant in the cooling conduit.
