Absorption Chillers

[insert presentation title into header and footer] Page 11

Advantages:

Are energy efficient where waste heat is

available and solar resource is high

Require much less electricity input than

vapor compression chillers

Provide a lower cost of cooling than Vapor

compression chillers

Disadvantages:

Require larger cooling towers than vapor

compression chillers

Not feasible for small applications

How it works?

[insert presentation title into header and footer] Page 12

Single Effect Absorption Chiller

8/12/2019 Masdar Solar Platform

13/13

Single vs. Double

Single effect chillers can use low temperature heatfrom flat plate collectors

Double effect chillers require medium temperature

heat which can be obtained from Fresnel collectors or

parabolic trough collectors

COP: Single = 0.7, Double = 1-1.4

Solution used: Single-Lithium Bromide,

Double- Ammonia

Double effect chiller divides the generator in to high

temperature and low temperature parts and thus

adopts a higher heat efficiency
