Conversion of ZT of a Thermoelectric to Refrigeration COP

The tool below is based on the Mathematical Computable Document Format (CDF). To download the required, free CDF player click here

The tool uses the following formula for the ZT to COP (refrigeration) conversion:

math_failure (math_unknown_error2): $CO{P_R} = \left( {\frac{{{T_c}}}{{{T_h} - {T_c}}}} \right)\left( {\frac{{\sqrt {1 + Z{T_m}} - {T_h}/{T_c}}}{{\sqrt {1 + Z{T_m}} + 1}}} \right)$
