known as green and energy saving,it is reliable in quality and used in electronics,communication,medical,military and so on.

1. It is applied in departments of industry, animal husbandry, military, research of medical science, etc. Because there is no limitation for the development of its miniature, it is especially suitable for the mini-type lower temperature or constant temperature parts of electronic devices, instruments and medical apparatus and instruments.In the medical fields, semicon refrigertor may be used for microtome and freezers. Also it may be used for cold  treatment instrument to treat skin diseases.2. Semicon cooler could be made for air conditioner and refrigerator to solve the problems of oscillation noise and leakage of refrigerant.It could also be applied for special occasions such as ships, submarines, satellite stations,airplanes,underground buildings,etc.3. Example:one 100-1iter semicon refrigerator,adopting 2×l27 pairs of elemonts,its working temperature difference is 30-45°C ,the surface area of heat sink is l.6-2.2 square meters,the temperature inside could be kept at 0-15°C (the ambient temperature is about 30°C and power consumption is about l00 watts(DC).4. Widely appfied for portable cool/warm chese and water drinker(cool/hot),semicon cooling and ventilating fan, etc.
