What Is Enhanced Vapor Injection?
Enhanced Vapor Injection system is made up of EVI compressor, EVI
technology and high-efficiency condenser. The combination of them provides high
performance.
The compressor adopts double-level throttling and mid-air-injection technology,
along with the flash evaporator to realize vapor injection effect. Under medium
and low pressure, the compressor pressurizes the refrigerant and synchronously vaporizing
it. Under high pressure, the compressor works normally. In low temperature, the
heating efficiency is largely raised. The EVI technology is widely used for
scroll and rotary type compressor.
Wotech has developed premium EVI heat pumps. For more please visit www.wotech.cn.
