1 2 3 4 == 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: - $COP_R = \left( {\frac{T_c}{T_h - T_c} \right)$ + $COP_R = \left( \frac{T_c}{T_h - T_c} \right)\left( \frac{\sqrt{1 + ZT_m} - T_h/T_c}{\sqrt{1 + ZT_m} + 1} \right)$ - + - \left( \frac{\sqrt{1 + ZT_m} - T_h/T_c}{\sqrt{1 + ZT_m} + 1} \right) +
