The effective thermal resistance for the BHE is defined by Equation 59.
a] are independent of the flow direction, it follows that the effective thermal resistance does not depend on the flow direction.
R/(Pi x C)) R = Effective thermal resistance
of chip in [degrees]C/W C = Effective thermal capacitance of chip in J/[degrees]C
uninterrupted constant thickness insulation systems) can be installed in series with the metal building systems described in this paper, and the effective thermal resistance can be determined by adding the thermal resistance values of the two systems.
Determine the effective thermal resistance for the metal building systems currently included in Standard 90.
The whole g-function curve does not need to be calculated since only three g-functions values are required for the three effective thermal resistances
Coefficients for the Effective Thermal Resistances
and Capacitances (De Carli et al, 2010) Type [K.
The results are plotted in terms of effective thermal resistances for a particular value of ground thermal conductivity, k=1 W/(m x K) [0.
The effective borehole thermal resistance is based on three elementary effective thermal resistances and is given by:
The effective thermal resistances
of these assemblies range from R-16 to R-25 depending on the specific product and the floor details.
h] represent effective thermal resistances for three thermal pulses.
y] = effective thermal resistances for the yearly thermal pulse, m*K/W (h*ft*[degrees]F/Btu)
