QM 33553 Abstract "Heat Pump" A working mixture for use in an absorption cycle heat pump comprises water as the volatile component and a novel absorbent comprising a mixture of sodium hydroxide, potassium hydroxide and caesium hydroxide such that the working mixture leaving the absorbent comprises, on a weight basis, from 15 to 85% caesium hydroxide, from 5 to 45% potassium hydroxide, from 0 to 35% sodium hydroxide and from 10 to 35% water. Such mixtures have low vapour pressures and low freezing points at the temperatures obtaining in the absorber (typically 65°C) and high vapour pressures at the temperatures (typically of the order of 180°C) prevailing in the vapour generator of the heat pump.
