制冷器件制冷特點:
   1．可使用常規直流電源；
   2．不使用制冷劑，不污染環境；
   3．體積小、重量輕，可大大節約建筑面積；
   4．可通過改變電流方向達到冷卻和加熱兩種不同的目的；
   5．冷卻速度快，其冷卻速度可通過調節工作電源來控制，便于控制；
   6．具有發電能力：若在致冷組件兩面建立溫差，則可產生直流電；
   7．無噪音、無磨損、運行可靠、維護方便。

Refrigeration characteristics:
   1. May use conventional DC power;
   2. Not to use refrigerants that do not pollute the environment;
   3. Both small and light and can significantly save construction area;
   4. To change the direction of electric current through both cooling and heating Different purposes;
   5. Cooling fast, its speed through conditioning cooling work Power to control and facilitate control;
   6. A generating capacity: If the two components in a temperature refrigeration Worse, they may produce direct current;
   7. No noise, no wear and tear and operational reliability, ease of maintenance.
