A circulating system for a steam jet refrigeration system

Development of a circulating system for a jet refrigeration cycle

“…In this chapter, detail of the design and construction of the WGF system is presented. provided by Srisastra and Aphornratana [2005]. The system configuration is similar to a conventional system, except that the mechanical pump is replaced with the WGF system.…”

“…Then, the mechanical pump can be removed, and the system can become a truly heat powered refrigeration cycle. Workless-Generator-Feeding (WGF) system [Srisastra and Aphornratana, 2005]. The system configuration is similar to a conventional system, except the mechanical pump is replaced with a WGF system.…”

“…A large amount of extra thermal energy was needed for this process and resulted in a lower COP compared with a conventional jet refrigerator using a mechanical pump (COP of 0.218). Srisastra and Aphornratana [2005] introduced the new circulation system to a steam jet refrigerator as shown in Figure 1.2. This system fed the liquid condensate back to the vapour-generator by means of gravitational force and the vapour-generator pressure.…”

“…The vapour-generator power inputs of both systems were almost the same as shown in Figure 4.3. [Srisastra and Aphornratana, 2005]. Vapour-generator saturation temperature (…”

“…From Srisastra and Aphornratana [2005], the experimental refrigerator was tested with a mechanical pump and a WGF system under various vapour-generator saturation temperatures (110°C to 140°C). The condensate temperatures were fixed at 20°C and 25°C.…”
