1. SNGE-13 Rotary compressor for conditioners Serikov New Generation Engineering serikov-nge.at.ua

2. Rotary compressor is using for work at ozone- safety refrigerants in the hermetic compressors Advantages: Increasing of cooling capacity valveless gas distribution implementation Low friction loss and gas exchange More low friction speed and small number of friction pairs Small contact loads The uniform rotation of all compressor parts Low cost of detail manufacturing High reliability compressor details Interchangeable details with a twin rotary hermetic compressors (shaft, rotor, coil, rotor of electric motor, bulb, filter-separator of oil) Available materials: gray cast iron, antifriction cast iron, nitride ferrous alloy Increasing the working volume of rotary compressor at the same bounding volume

3. Advantages: Increasing the coefficients COP and ERR on 9…17%; Easy assembly High efficiency High compression Small harmful amounts Reducing energy consumption Reducing mechanical losses Reducing vibration and noise Low ripple Disadvantages: Using anti-friction cast iron and nitride ferrous alloy

4. For better and detailed compressor design researching have been depicted some elements of it. Picture 1. 1. Compressor details (top cover, section, bottom cover, shaft, spiral, internal rotors, external rotors, propellers) have been presented at the picture 1. 2. Ratio of the shaft to the external rotor is 2:1. 3. Gas distribution is carried out through radial holes at the external rotors.

5. The harmful volumes at the different versions of compressor design are 1,97% - type1, 1,3% - type3 and 0,3% - type5. We have developed 12 types of compressors on a base of mechanism to have been presented at the picture 1. These compressors types have to work with different refrigerants (R410 and CO 2 ) and have performed with 1- stage and 2-stage compression.

7. Ecological aspects: Work of compressor on ozone-safety freon R410a Possibility of work on СО 2 ; Reducing energy consumption Reducing vibration and noise

8. Technical solutions implemented at compressor are innovative and have been patenting Innovative designs have been developed by Ievgen Serikov Ievgen Serikov has developed 12 types of compressors included Know-How
