The CNPM thermal heat pump. 1. General description and thermodynamic analysis.

Author(s) : ANGELINO G., FERRARI P., GALA M., et al.

Type of article: Article, IJR article

Summary

In this paper, the selection criteria for the working fluid - a completely fluoro-substituted hydrocarbon - and the main thermodynamic data of both power and heat pump cycles, are discussed; the finally adopted plant configuration is described, with particular emphasis on the influence exterted by the working fluid nature on the heat exchangers and turbo-machinery dimensions and performance. A discussion on the merits of the single fluid solution (i.e. the same working fluid in the power and the heat pump cycle) and dual fluid solution is also carried out. The feasibility of a lowtemperature heat distribution, based on compact-surface, natural-draft convectors, with the relevant advantages on the Rankine and heat-pump cycles, is also investigated. Finally, the expected overall system performance is given, both at design and part-load conditions. As a premium for the rather complex but efficient thermodynamics of the system, significant energy savings are obtained in all situations.
