The working principle of the refrigerator condenser : air conditioning refrigeration system will produce the cool air, then the refrigetator pumps them from the freezing chamber to the refrigerating chamber, which to ensure a sufficient supply of cooling air; at the same time, the steam is pumped excess from the freezing chamber to prevent the junction refrigerators cream, which is the origin of the word frost-free refrigerator.

The Specification of Hengdrive brushless fan : a three-phase brushless outer-rotor motor, 12V DC power supply, 1800 rpm, 2W, ultra-quiet, low-power, which is very consistent with new environmental advocates white goods. The long-time life is good to meet the fridge characteristics of long-term work.
