It is a very good refrigerant. At about 200 btu/lb (latent heat of vaporization) it is 3 times better than most HFC or HCFC refrigerants.
Ammonia is better! 550 Btu/lb and 8 to 10 times better than HFCs or HCFCs.
Water is better still... 970 BTUS/LB! It really is the best. Cheap and available almost everywhere!
