A recirculating He 3 refrigerator is described in which the compressed He 3 is cooled below 4.2 K by means of a heat exchanger rather than a pumped He 4 bath. This design eliminates the requirement for large capacity pumps and a separate, pumped He 4 bath. In continuous operation, a refrigeration po
We examine the performance of a dilution refrigerator from an enthalpy standpoint. Taking into account imperfect heat exchange due to Kapitza resistance and temperature dependent effects allows calculation of the effective surface area in the heat exchangers. Knowledge of the effective surface area
