Superconducting detectors for quantum key distribution require expensive cooling but have advantageous detection properties. A linear programming algorithm and heuristic for network cooling placement are proposed and validated. Co-locating cooled detectors provides cost-effective solutions even when cooling costs exceed the equipment cost of multiple links.
