Unclear princilple of the inverter compresor
Hi guys! Can anybody help me?I am interested in knowing well the principals of "the inverter compresor"(Singel and three fase current)for example:I don't know well the moment of strarting without capacitor or are these polyphase motors ?
does the inveter packet change the characteistichs of the monophase current like the tension and frequence or it changes the monophase current into a three phase current?If it is possible I'd like you to provide me with a catalogue(guide)/PDF for this problem.
Thank you!!!!

Re: Unclear princilple of the inverter compresor
Hi, if you search this site you should find what you want, but quickly to answer your question,
Yes, Inverter compressors are poly phase (typically 3) motors. Older units are AC motors, newer are Permanent magnet rotors which are digitally commutated.
Input monophase Power is recified to DC and then converted (chopped or switched) back to 3 phase AC. The frequency and voltage of the output is controlled by the electronics to limit the current.

Re: Unclear princilple of the inverter compresor
These arrows indicates cooling and heating operation direction (and states) of refrigerant and not temperature of refrigerant. Also, you should follow size of arrows (indicates high or low pressure) thru the 4-way valve and then you will see that it don't go back to suction accumulator. That is like driving thru familiar streets. You always drive by memory, and when you pay traffic penalty, you realize then that someone changed traffic signs.
