Abstract:
A method of cooling a refrigerant includes providing a condenser (200) including a condenser shell (202) that contains a condenser chamber (204), a condensing conduit (209), and a cooling conduit (217); condensing a refrigerant within the condenser chamber (204) from a vapour phase to a liquid phase by exchanging heat from the refrigerant in the condenser chamber (204) to a fluid in the condensing conduit (209); supplying a first portion of the condensed refrigerant to the cooling conduit (217) via a first expansion valve (310) such that the first portion of the refrigerant decreases in pressure and temperature before entering the cooling conduit (217); and cooling the refrigerant in the condenser chamber (204) by exchanging heat from the refrigerant in the condenser chamber (204) to the first portion of the refrigerant in the cooling conduit (217).
