== 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>COP_R = \left( \frac{T_c}{T_h - T_c} \right) </math>

\left( \frac{\sqrt{1 + ZT_m}  - T_h/T_c}{\sqrt{1 + ZT_m}  + 1} \right)
