CALCULATION OF THE THERMODYNAMIC PROPERTIES OF REFRIGERANTS 12, 22 AND 502 USING A DIGITAL COMPUTER

摘要

Designing, testing, or simulating refrigeration compressors requires the evaluation of the thermodynamic properties of the working refrigerant. These properties are most commonly obtained from property tables or property diagrams such as those published in the ASHRAE Handbook of Fundamentals (1). However, these two methods are time consuming and usually result in a loss of accuracy. A simple and accurate method of making these calculations is to develop equations for the thermodynamic properties and use a digital computer.
