We will then show that, under proper conditions, single-particle tunnelling in NS junctions can lead to refrigeration: heat is extracted from N and the temperature of the electronic population decreases accordingly. Andreev processes, however, generate Joule heat that is deposited in the normal metal electrode. At low temperatures this heating dominates over the single particle cooling.
