•What is Performance Evaluation for a Chiller?
Performance Evaluation is a detailed engineering analysis of the actual performance of the chiller system including the individual components creating a snapshot of the actual operation. Detailed thermodynamic system analysis models are used to evaluate the performance of the system. Performance Evaluation results are presented in a graphical manner and include: Chiller system efficiency, Potential energy & cost savings, Heat Exchanger performances, Compressor performance, Electric motor, steam turbine, gas-fired engine performance. Hudson Technologies provides a performance evaluation for any packaged chiller system using their proprietary thermodynamic system models. Alternatively, for a custom built chiller / refrigeration system, Hudson Technologies can develop a performance evaluation model that predicts the operation and performance of the system.
