Enhanced Vapour Injection (EVI)

Enhanced Vapour Injection (EVI) 

EVI Compressor systems present benefits over standard refrigeration compressors due to the following:

• Capacity Improvement

The capacity is improved by increasing the enthalpy difference in the system rather than increasing mass flow. This is accomplished without increasing displacements.

• Increased COP

The efficiency improves due to the fact that the gain in capacity is greater than the increase in power that the compressor consumes.

• Cost and Energy Advantage

Because a smaller size compressor can be used to achieve the same capacity as a larger conventional model, there is an inherent cost advantage.
