Experimental Tri-generation System

Figure 7.5 shows a schematic diagram of the experimental SOFC liquid desiccant tri-generation system. The system is divided into three main components:

  • (1) SOFC power generation
  • (2) SOFC WHR circuit
  • (3) Liquid desiccant air conditioning.

A 250 We micro-tubular SOFC has been acquired by The University of Nottingham for tri-generation integration, and is designed to operate with propane (C3H8) as a

Fig. 7.5 Experimental tri-generation system schematic fuel. The SOFC WHR system was developed for this project by The University of Nottingham. As a result actual thermal output values for the unit were not known before testing; however the manufacturer estimated that 500-1000 W was available for heat recovery. The SDCS, documented in Chap. 6, is employed as the thermally activated cooling technology in the experimental tri-generation system.

The proposed tri-generation system is truly multi-functional, and can provide electrical power and heating through the SOFC CHP unit, in addition to dehumidification and cooling/thermal comfort control through the liquid desiccant air conditioning unit. The novel tri-generation system is well suited to hot and humid climates, and applications that require onsite electrical power and simultaneous heating or dehumidification/cooling. Next, Sect. 7.3.1 describes the micro-tubular SOFC CHP component.
