Summary

In many industrial processes and buildings, there is a need for both cooling and heating. Often, these demands are supplied by several systems, which results in energy waste, in addition to representing extra costs. The FORCO2 project, presented in this paper, aims at designing a fully reversible unit that can provide heating, cooling, or both simultaneously, in particular by use of an additional air heat exchanger that can efficiently be used either as evaporator or gas cooler. The performance of the system is improved by addition of high-capacity high pressure plate heat exchangers and ejectors. The design and the different modes of the system are described and experimental results for a 1500 kW prototype are presented. A theoretical comparison of the system to the traditional separated cooling and heating systems shows a significantly higher SCOP.
