== 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 [http://www.wolfram.com/cdf-player/ click here]

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

<math>\[CO{P_R} = \left( {\frac{{{T_c}}}{{{T_h} - {T_c}}}} \right)\left( {\frac{{\sqrt {1 + Z{T_m}}  - {T_h}/{T_c}}}{{\sqrt {1 + Z{T_m}}  + 1}}} \right)\]</math>
