Information

This package cointains flow coefficients that are already specified. This means that the calculation approaches of the flow coeffiencient presented before are adapted for a specific expansion valve type and a specific refrigerant.

Naming and abbreviations

In the following, a guideline of naming flow coefficient models is summarised:

Approach of calculating flow coefficient _ Valid refrigerants _ Type of expansion valve _ Diameter of cross-sectional area of expansion valve

1. Approach: Approach of calculating flow coefficient, e.g. polynomial or power.
2. Refrigerant: Refrigerants the flow coefficent model is valid for, e.g. R134a or R410a.
3. Type: Type of expansion valve, e.g. electric expansion valve (EEV).
4. Diameter: Diameter of the cross-sectional area of expansion valves if it is fully opened, e.g. 1.6 mm.
