Frequency conversion air conditioning really save electricity?

First,the frequency conversion air conditioning really save electricity,frequency conversion air

conditioning energy saving principle 1.The principle of frequency conversion air conditioning is air conditioning adopted more advanced 220v ac electric motor stechnology,the startup voltage is small,but under the condition of low voltage and low temperature start,that www.dongfeng-motor.com in some areas due to the low voltage instability or winter indoor temperature and air conditioning,it is hard to start a certain improvement effect.Due to realize the stepless variable speed compressor,it can also adapt to more widespread refrigeration and heating demand.2.Simply put on the principle of frequency conversion air conditioning is in the structure of conventional permanent magnet motors for saleair conditioning increased by a frequency converter.

The heart of the air conditioning compressor,its speed directly affects the efficiency of the use of air

conditioning,frequency conversion air conditioning inverter is used to control and adjust the

compressor speed control system,make it always in the best state of rotational speed,thus,improve the

energy efficiency ratio is larger than that of conventional air conditioning energy saving 20% ~

30%.Second,the frequency conversion air conditioning really save electricity,high frequency operation

more efficient 1.The frequency conversion air conditioning in addition to just boot with high

frequency operation,other operating at low frequency,most of the time consumed power is far less than the air conditioning that decide frequency.Compressor is Motor vehicle a large energy consumption of air conditioning,its rated output accounted for about 90% of the air conditioning machine power,the other 10% for fan motor and other electric parts;The frequency conversion air conditioning compressor

efficiency is higher than the ordinary air conditioning that decide frequency compressor.2.The number of frequency conversion air conditioning open stop is much lower than that of the air conditioning that decide frequency switching frequency,the air conditioning that decide frequency boot will consume a lot of energy.Ac frequency conversion air conditioning than the air conditioning that decide frequency to save electricity by 30%,while dc frequency conversion air conditioning power saving 50%.

The cause of the slow speed motor load runtime

1),2) the power supply voltage is too low,squirrel cage rotor broken bar 3) group,coil,or coil

short-circuit point 4),the coil or coil group has 5),the reverse phase winding 6) 7),overload,wound

rotor type a wholesalemotor.blogspot.com phase break 8),wound rotor type motor starting rheostat poor contact 9),brush and slip ring poor contact 2.The motivation of the voice is not the cause of the normal during operation 1),the phase of the stator and rotor brush 2),3),the rotor rubbing rotor blades touch shell 4) insulation paper,bearing the lack of oil 5),the motor with sundry 6),motor with buzz two phase operation 5.The motor shell charged reasons: 1),2) the power cord and ground wire to make wrong,be affected with damp be affected with damp,motor winding insulation aging reduce insulation performance (3),4) lead and junction box body contact,local winding Insulation Motor vehicle damage to wires touch shell relaxation stabbed 5),core wire 7) 6),grounding line failure,damage to the wiring board,or on the surface of the oil too much Excessive sparking 6.Winding rotor slip ring 1),2) slip ring surface dirt,brush pressure is too small (3) 4) jams,brush in the brush,brush deviating from the neutral position 7.The motor temperature rise too high or the reason of rotor balancing machine smoking 1),2) power supply voltage is too high or too low,overload 3),4),the stator winding single- phase running ground 5),6) bearing damage or bearing is too tight,the stator winding Group of turns or interphase short circuit 7),environmental temperature 8),motor fan duct not free or damaged.
