Thermoelectric Temperature Differences
In many situations, the object being cooled generates little or no heat. In these cases, the combination of TE cooling and thermal insulation produces large temperature differences. For a hot side around room temperature, temperature differences of about 72°C and 125°C can be achieved by single-stage and multi-stage TECs, respectively. COP is low when a TEC is operated near its maximum °T, but this can be acceptable when the heat load is small.
