Development of properties database of carbon dioxide refrigerant

Abstract

At the beginning of the 20th century, refrigeration was well-established on an industrial scale but researchers still finding the best refrigerant to be used in widely application. This is because due to the people start to invent a system such as air conditioning and refrigeration using suitable refrigerant. People may famous with refrigerant R-134a that has been used all over the world in refrigeration and air conditioning system. But still, they have their own disadvantages that unsuitable to mankind. Now, for Carbon Dioxide (R744) refrigerant will become a trend in industries. A few advantages of Carbon Dioxide help people to choose as a refrigerant. Hence, a published table for Carbon Dioxide (R744) refrigerant had to be created. This table is properties databases that contain all properties and states of Carbon Dioxide. The following set of tables contain all properties will be develop by using Visual Basic version 6 software. A suitable format will be organized to make sure this database is a friendly application and can be used by all kind of researchers in industries.
