Résumé

In this study, industrial heat pump which can generate low pressure steam was developed. The heat pump uses process waste heat of 50-60°C to generate 120°C, 2kgf/cm2 steam. By implementing this, the overall thermal energy efficiency of a factory can increase. In case of R134a, the discharge temperature and pressure of compressor was expected to be in supercritical state around 200°C/10 MPa. To locate operation points in lower temperature and pressure zone, R245fa was selected as a working fluid. Cycle and system design was performed based on R245fa properties. With the experiment results of small-scale, reciprocating-compressor system, large scale system design of screw-compressor was carried out. Since this system was to be applied to actual operation, control logic with high reliability was also developed. After in-lab tests, the heat pump was installed to supply steam for waste scrubbing process in a chemical factory.
