Summary

This report was prepared as an account of work sponsored by ARTI under its "HVAC&R Research for the 21st Century Program". The purpose of this research was to investigate the economic feasibility of a water-based vapour compression chiller with a nominal capacity of 1000 tons. Low-level models of various potential cycle configurations have been constructed and the results of simulations for each cycle configuration are described. More detailed component level models were developed to accurately size equipment and predict system performance for the most attractive cycle configuration. These component models address issues that are particularly crucial in water as refrigerant cycles, such as compressor discharge superheat and refrigerant side pressure drop. Where possible, these component models were verified through comparison against the current state-of-the-art technology for large chillers using R134a as a refrigerant. The capital cost and the expected operating costs are determined to quantify the payback time associated with using water as a refrigerant relative to traditional halocarbon refrigerants currently in use.
