Types of Water Chillers
notes
Absorption Chillers Offer Choice
▲Avoid high electric demand charges
▲Minimal electricity needed during emergency situations
▲Waste heat recovery
▲Cogeneration

Absorption water chillers generally have a higher first cost than vapor- compression chillers. The cost difference is due to the additional
Because the absorption chiller uses only a small amount of electricity, backup- generator capacity requirements may be significantly lower with absorption chillers than with
Some facilities, such as hospitals or factories, may have excess steam or hot water as a result of normal operations. Other processes, such as a gas turbine, generate waste steam or some other waste gas that can be burned. In such applications, this otherwise wasted energy can be used to fuel an absorption chiller.
Finally, cogeneration systems often use absorption chillers as a part of their total energy approach to supplying electricity in addition to comfort cooling and heating.
