热电的应用已从传统的单一制冷或发电扩大到世界能源消耗严峻的余热回收。随着生活水平的提高，现在越来越多的中国家庭使用家用空调。 2003年我国爆发“非典”后，新风热负荷引起的家用空调耗电比例有所上升，只要新风供应充足，就可以有效预防。湖南大学热电实验室研制出了一种新型热电家用换气机样机，对空调房间排风进行热回收。该通风机中集成了热电热交换器和平翅横流热交换器。对该通风机进行了研究，从性能系数、制冷制热功率、新风处理温差等方面对其制冷（制热）性能进行了评价。整个实验发现该呼吸机的性能系数超过2.5。本文对该呼吸机的最佳工作参数进行了研究。这项工作还讨论了性能和市场前景的潜在改进。
Applications of thermoelectrics had been enlarged from conventional single refrigeration or generation to waste heat recovery with tough energy consumption of the world. With improvement of living standard more and more domestic air-conditioners are used in Chinese families now. Percentage of power consumption of domestic air-conditioner caused by heat load of fresh air supply increased after SARS, which could be prevented efficiently with sufficient fresh air supply, broke out in China in 2003. A novel prototype thermoelectric domestic-ventilator with heat recovery of exhaust of air-conditioned room had been made in Hunan University thermoelectric lab. A thermoelectric heat exchanger and a flat-fin cross flow heat exchanger were integrated in this ventilator. This ventilator was investigated and its cooling (and heating) performance were evaluated in terms of the coefficient of performance, cooling and heating powers, and being handled temperature difference of fresh air. The coefficient of performance of this ventilator was found to be over 2.5 in the whole experiment. The optimal working parameters of this ventilator were studied in this paper. The potential improvements in performances and market prospects were also discussed in this work.
