The invention discloses a high-voltage friction nanometer power generation defroster which comprises an alternating current motor, a friction nanometer power generator, a voltage doubling rectifying circuit and a fin of an evaporator. The friction nanometer power generator is arranged at one end of the alternating current motor; and the output end of the friction nanometer power generator is connected to the fin of the evaporator through the voltage doubling rectifying circuit. The high-voltage friction nanometer power generation defroster provided by the invention adopts a friction nanometerpower generator technology, and the output current is a microamp order and is six orders of magnitude less than the amp-order current produced by a high-voltage inverter, so that the consumption of the friction nanometer power generator technology is less on the aspect of the generated power consumption, and the energy consumed for selecting the high-voltage friction defroster is far less than theenergy consumed by the inverter. The high-voltage friction nanometer power generation defroster provided by the invention adopts the friction nanometer power generator technology, so that the currentobtained under the rotary speed being 400rpm is 100 muA and is harmless to a human body. Compared with the inverter, the high-voltage friction nanometer power generation defroster provided by the invention is portable and can be carried; and compared with the high-voltage inverter, the cost is greatly reduced.
Description
Technical field [0001] The present invention relates to a defrosting apparatus, and more particularly to a high-pressure friction nano-generating defrosting device. Background technique [0002] The refrigeration system includes four parts of the air compressor, evaporator, expansion valve, and condenser. The frosting problem of refrigeration system in life is very common. Since the relative humidity in the cold storage is relatively high, when the refrigeration system is operating normally, the surface temperature of the evaporator is much lower than the dew point temperature of the air, and the moisture in the air is precipitated and condensed on the evaporator tube wall. When the tube wall temperature is lower than 0 ° C, the water dew condenses the cream. With the thickening of the frost, the heat transfer of the evaporator is deteriorated, the effective air flow area between the evaporator fins is reduced, and the flow resistance of the air is increased, and the flow rate of...
