Ay. Khan, SENSITIVITY ANALYSIS AND COMPONENT MODELING OF A PACKED-TYPE LIQUID DESICCANT SYSTEM AT PARTIAL LOAD OPERATING-CONDITIONS, International journal of energy research, 18(7), 1994, pp. 643-655
Prediction of annual energy consumption requires the partial load perf
ormance evaluation of each component in an air conditioning system. A
packed-type or a coil-type liquid desiccant apparatus is an essential
component of a hybrid liquid desiccant system. Therefore, predicting t
he hour by hour performance of a packed-type hybrid liquid desiccant s
ystem to estimate its annual energy consumption requires that the perf
ormance of a packed-type system be known at partial load conditions. F
or this purpose a detailed sensitivity analysis of heat and mass trans
fer performance of a packed-type liquid desiccant system is carried ou
t to identify important performance parameters. Two output parameters
- enthalpy effectiveness and humidity effectiveness - are defined to p
resent the results. Based on the conclusions drawn from the detailed s
ensitivity analysis, a simple model is developed to predict the perfor
mance of an absorber and a regenerator at partial load operating condi
tions. Performance predictions using the simple model are compared wit
h the predictions from the detailed analysis along with another existi
ng model which is available in the literature. The simple model is in
excellent agreement with the predictions of other two models.
