One of the main components of a refrigeration system is the expansion valve. Its correct sizing is critical to ensure the optimum and most efficient operation.
The APP Castel Selector supports the designer, or refrigeration technician, in sizing the electronic expansion valve and in matching it to the compatible PEGO electronics, thus providing all the information necessary for the complete configuration of a refrigeration system.
The selection of Castel components is enriched with new products starting from the complete range of check valves, the full range of Castel indicators, plus the range of ball valves and their relative pairing with the electric actuators proposed in the Castel catalog.
The tool proposed by Castel helps the designer, and the refrigeration technician, to calculate the pressure drop generated by each passive component of the Castel family, thus providing all the information for a correct selection.
In addition to providing the fluid dynamics calculations, this application also guides and supports the designer during the pairing of ball valves with an actuator and its adapter, providing the complete list of components to be ordered.
The Castel Regolo APP is able to quickly calculate the relationship between the pressure and temperature of the most common refrigerants in saturation conditions.
The app is able to provide for each refrigerant also the thermodynamic qualities of each gas, including the global warming potential (GWP) and the ozone depletion potential (ODP).
Within the app it is also possible to make a direct comparison between two different refrigerants, comparing at the same time the difference in saturation temperatures relative to a common reference pressure in the same screen view.
All calculations in the app are performed using extended curve fit models, based on the results of Refprop. In all zeotropic blends, it is also possible to see both the dew point and the bubble point, thus calculating the glide value.
Simplicity, solidity and safety are the major qualities that distinguish this expansion valve, capable of operating up to 90 bar, as well as being able to operate even with pressure differential values higher than 40 bar.
The 56 family of electronic oil level regulators makes the control and the regulation of the oil very easy and responsive in all installation conditions, both on new systems and as a replacement for existing systems.
