Abstract
1-chloro-2,2,2-trifluoroethane (refrigerant 133a) is dissolved in a furan-derivative absorbent, and especially an ether of tetrahydrofurfuryl alcohol, to form an absorption refrigerant pair composition. It exhibits a good combination of performance, capacity, stability, low toxicity and convenient operating pressures. These compositions are useful in methods of absorption refrigeration, cooling and heating and especially in an absorption heat pump.
