highly recommended in several energy applications in non-residential buildings
such as hospitals and hotels. Time of use and cooling load profiles are
significant factors that should be carefully considered either in chiller plant
design or in chiller sequencing operation. This article aims to present an
operation planning of HCP which consists of both electric and non-electric
chillers. Four operational strategies are proposed and solved to compare their
coefficients of performance and economics of running costs. A typical hotel
building located on the Nile river in Egypt is selected to perform the current
thermal and economic case study. The total cooling load profile of this hotel
building is 4000 refrigeration tonnage (TR), which </span></span></span><span style=\"font-family:Verdana;\"><span style=\"font-family:Verdana;\"><span style=\"font-family:Verdana;\">is </span></span></span><span style=\"font-family:Verdana;\"><span style=\"font-family:Verdana;\"><span style=\"font-family:Verdana;\">simulated to optimize chiller sequence of operation and to select optimal
design conditions of both numbers for electric and non-electric chillers used
in HCP. The results of this comparative study for running cost are defined
using various design configurations with different several chiller sequences
available for each configuration. Then, the results of COPs, and operational
running cost and initial cost are presented in this article also. The
comparison aims to find the optimal design and operational sequencing for HCPs
on thermal basis and economic analysis which were attached in this article.
Recommendations and suggestions for future work are attached at the end of this
article.</span></span></span>
