Manufacturers of refrigerants, controls, and other suppliers distribute hundreds of thousands of pressure-temperature charts to the trade every year. It would be rare indeed to find service ...
Low-pressure controls are used on many medium-temperature refrigeration systems to control case temperature. In order for this type of control to work properly, both its cut-in and differential ...
A new method to estimate equilibrium phase distribution ratios (K values) improves on the shortcomings of older methods. The method is based on the generalized fugacity charts of Lewis, Kay, and ...
