Water is the preferred liquid although ammonia, lower alcohols, and polyols such as glycerol, glycols, polyglycols, glycol ethers, lower aliphatic amines and alkanol amines, and mixtures thereof, may be used.Field of SearchAbsorber-still, e.g., intermittentWith solid sorbent Particular gas-liquid contact in sorber Evaporator-condenser unit With sorber-generator cooling means Internal liquid flow to external cooler Vapor-liquid contact in reabsorber forming liquid refrigerant Means causing cooling fluid contact with sorber and/or condenser Intermittent operating of generation and sorption cycle | |
