A Realization of a London-Clarke-Mendoza Type Refrigerator
The refrigerator uses the heat of mixing at constant osmotic pressure between 3He and 4He, and has attained a temperature of 0.22°K in preliminary runs. The eight (probably) essential parts of the cycle are the condenser (C), expansion valve (V), heat exchanger (I), mixing chamber (M), superfluid duct (D), helium mixture funnel (F), evaporator (E), and circulation pump (see Fig. 1).
