Abstract
Theoretical, evaluations of ammonia - water heat pump
systems for various applications and the construction and
experimental evaluation of absorption heat pump for
cooling is presented. The theoretical evaluations include;
(i) theoretical evaluation of the various tracking modes
as a means of solar energy augmentation for solar flat
plate collectors, (ii) the evaluation of performance
of solar fiat plate collectors as a energy source for
absorption heat pump systems , (iii) application of
Chebyshev polynomials for the evaluation of thermodynamic
property data equations for ammonia-water mixtures for
absorption heat pump systems and (iv) thermodynamic
analysis of ammonia-water absorption heat pump systems
operating in the following modes; (a) conventional
(heating and cooling) (b) reversed and (c) experimental. A
5 kWatt experimental solar-powered absorption heat pump
system was constructed using locally available materials
and skills. The simulated performance results and
experimental performance data for the absorption heat pump
system for cooling showed great potential for solar
cooling in Nigeria.
