Air conditioning with ammonia for district cooling.

Author(s) : TOTH S. J.

Summary

Chilling water with ammonia is not new. Dairies and industries have been doing it for years. For district cooling, water or a glycol-water mixture is cooled by ammonia chillers as is done by CFC chillers, and distributed to users for air conditioning. One of the major differences is that ammonia has zero ozone-depleting potential and zero global-warming potential. Personnel and environmental safety are overriding considerations. Both primary and secondary refrigeration systems operate fully automatically without the presence of operators. Fifteen different safety features are utilized in designing the new systems. Performance comparisons show that ammonia is clearly the refrigerant of choice for most systems, especially for district cooling systems.
