sunpeek.components.fluids.CoolPropFluid

class sunpeek.components.fluids.CoolPropFluid(fluid=None, concentration=None)

Bases: Fluid

High level class for interface with CoolProp incompressible fluids.

Input and output units to CoolProp are standardized and thus don’t need to be specified.

Variables:

• fluid (CoolPropFluidDefinition) – User-supplied string that must uniquely define a fluid within the CoolProp incompressible fluids. See `CoolProp Incompressibles`_.

• concentration (pint.Quantity or dict) – If fluid does not require concentration, leave at default None. concentration is interpreted as mass concentration for `mass-based binary mixtures`_. concentration is interpreted as volume concentration for `volume-based binary mixtures`_.

Raises:

ValueError – If concentration is given for pure fluid or missing for mixed fluid, or concentration is wrong Quantity.

Methods

__init__([fluid, concentration])	A simple constructor that allows initialization from kwargs.
get_density(te)	Calculate density of fluid at given temperature and self.concentration :type te: pd.Series :param te: Temperature for which density is evaluated.
get_heat_capacity(te)	Calculate heat capacity of fluid at given temperature and self.concentration :type te: pd.Series, scalar or vector :param te: Temperature for which heat cpaacity is evaluated.

get_density(te)

Calculate density of fluid at given temperature and self.concentration :type te: pd.Series :param te: Temperature for which density is evaluated. :type te: pd.Series

Return type:

pd.Series

get_heat_capacity(te)

Calculate heat capacity of fluid at given temperature and self.concentration :type te: pd.Series, scalar or vector :param te: Temperature for which heat cpaacity is evaluated. :type te: pd.Series, scalar or vector

Return type:

pd.Series

property query_str

String to be sent to CoolProp backend, adds concentration to self.coolprop_fluid, if necessary. :rtype: str
