Leading DC inverter scroll compressor
Inverter air-cooled modular units adopt the advanced DC inverter compressor. Together with the EVI technology, the overall unit heating capacity is increased by about 14%. This can guarantee low-temperature heating performance for users, and substantially reduce the heating operation costs. Advantages include efficient running, high stability, long service life, and low noise.
1 Advanced EVI technology，Enhanced system capacity, faster heating.
2 Optimized asymmetric vortex line, The new asymmetric vortex line can reduce the loss caused by leaks and reduce invalid overheating. It is more adapted to APF conditions and can improve compressor efficiency.
3 improve compressor efficiency. Non-contact oil film seal, The radial and axial directions of compression cavity adopt non-contact seal. The lubricant oil film can reduce friction, improve volumetric efficiency and increase product reliability.
4 Centralized-coiler motor, Lower motor coils can reduce copper loss. The efficiency at medium and low speeds is higher and is more adapted to APF conditions.
5 High speed, 10~140 RPS Virable speed and wide capacity range.
6 Dynamic oil balance, With the patented oil balance technology, the compressor is highly reliable and flexible. There is no limit to installation height, and compressors of different discharge capacities and different speeds can be used in parallel
7 Oil pump filter, Purities (if any) are filtered to guarantee oil cleanness.
8 Volumetric oil pump, It can ensure necessary oil supply under variable speeds to increase compressor reliability.
9 Internal oil circulation, Lubricant internal circulation can reduce overheating loss and oil discharge rate, and increase efficiency and reliability
10 High-pressure cavity, Large volume for discharge and buffer to reduce air flow noise and vibration during system running.
11 Highly reliable bearings, Cylindrical bearing and self-aligning ball bearing are adopted to increase the compressor reliability.
12 Intermediate pressure servo mechanism, The intermediate pressure is dynamically adjusted based on the operating pressure, to achieve radial flexibility and optimize the engagement of stationary scroll and orbiting scroll.
13 Pressure relief valve Energy efficiency at partial load is increased to adapt to ratio of transformation and improve product performance
EVI principle
The EVI system is a new system consisting of EVI compressor, EVI technology, and efficient supercooler. Asuction port is added to the medium pressure cavity of the compressor scroll to supplement air using medium pressure, increase the compressor's air discharge, and improve the heating capacity at low temperatures. It has the advantages of high-efficiency operation during cooling and improvement in heating performance under severe cold during heating, which is safe and reliable. Create a second suction port in the scroll plate to supplement air through the second suction circuit, increase the refrigerant discharge, and increase the enthalpy difference of the main circulation refrigerant.
