Until 1950 ’ s with the discovery of high performance materials , thermoelectric refrigeration technology began to be applied in engineering fields , but compared with other refrigeration technology such as mechanical refrigeration and absorbed refrigeration , its efficiency is lower , which limits its application and development in building environment refrigeration fields . however , thermoelectric refrigeration has many unique advantages , such as compact structure , no moving parts , no pollution , precise control
由于受材料优值系数仍然不够理想的限制,其效率不及机械制冷或吸收式制冷等其他制冷形式,因而在建筑环境制冷领域限制了这种技术的应用和发展,但热电制冷仍然具有许多独特的优越性:系统简单、无机械传动、无工质运行、调控简单精确等等。
