摘要
本文指出热电制冷是21世纪极有发展前景的制冷新技术,但目前发展水平还不够高。由于制冷系数低、性能价格比较低及对电源要求较高等因素,目前发展受到了制约。新材料、新工艺、新技术及新电源的突破发展,是热电制冷进入一般工业和家庭生活的前提。
Thermoelectric refrigeration is a great future and a new refrigeration technology in 21 century, but its developmental degree is not high now. For its coefficient of performance is lower, its performance-to-price ratio is lower ,and the battery required has to be excellent, because its development is restricted now. The break throughs in new material, in new technology, and in new battery are the premise that thermoelectric refrigeration will go into common industry and home life. [
