Retelling analysis

The paper under discussion is entitled “a circulating system for a steam jet refrigeration system”. It is written by Passakorn Srisastra and Satha Aphornratana. This paper provides information about proposes a circulating system for a steam jet refrigeration system that does not require mechanical power. In this system, the liquid from the condenser is fed to the boiler by means of the boiler pressure and gravity force. This feeding system was tested separately. It was found that the heat input to the boiler was relatively similar to the one in a conventional system using a mechanical pump. The steam jet refrigerator employing this workless boiler feeding system was also tested. It was shown that this system gave a similar COP to that from a system using a mechanical pump.

It deal with the problem relating to workless boiler feeding system . This workless boiler feeding system was tested under various boiler saturation temperatures. The author points out that the results applied to a steam ejector refrigerator without any degradation in system performance compared with a system employing a conventional mechanical boiler feed pump. The use of this workless boiler feeding system would make a steam ejector refrigerator become a true heat powered refrigeration cycle.

A careful account is given to effect of the feeding tank’s volume on the system. Enlarging the feeding tank may cause temperature variation inside the boiler tank during the feeding period. However, decreasing the size would make the filling and emptying phases occur more frequently which creates rapid change of temperature inside the tank, and thermal fatigue problems may occur in long term operation. Due to these factors, a long term investigation is needed to prolong its operation and obtain satisfactory performance.

As a conclusion me I think in this paper were shown very interesting proposal, how to replace the mechanical pump without any degradation in system .I would say that ,I hope that information from paper will be helpful for my thesis.
