What Are the Features of EVI Heat Pumps?
1. Energy-saving and efficient.
The COP of all the models is averagely 4.32, which stands for the highest
standard of the world. Due to the EVI technology, massive cost for heating and
cooling is largely saved.
2. Running normally even in ultra-low temperature; reliable.
EVI heat pumps realize the ability to work under -25℃ to 29℃. EVI
technology increases the compressor’s heating capacity under low temperature.
20% to 50% heating capacity is raised under -15℃.
The outside unit loses its heat exchanging ability under low temperature.
The returning gas refrigerant is reduced, lessening the heating capacity of the
compressor. But through refilling gas refrigerant with the mid pressure injection
nozzle, the gas exhaust is increased. While indoor the circulating refrigerant
for the heat exchanger goes up to realize pushing the heating capacity. EVI
heat pumps are more suitable for the cold areas.
