EVI (Enhanced Vapor Injection) technology is an advanced vapor injection system used in heat pumps to increase their efficiency, especially in low outdoor temperatures. This technology allows heat pumps to operate efficiently even at extremely low air temperatures, thereby expanding their use in colder climates. In traditional heat pumps, efficiency decreases as the outdoor temperature drops, as it becomes more difficult for the system to extract heat from the environment. EVI technology solves this problem by introducing an additional vapor injection cycle into the compressor, which increases system pressure and temperature, improving heat transfer and increasing the overall performance of the heat pump by 12%.
The use of EVI technology allows:
Increase the coefficient of performance (COP) of the heat pump, thereby reducing energy consumption and operating costs. Extend the operating temperature range at which the heat pump can operate efficiently, providing comfortable heating even in very cold weather.Reduce the defrosting time of the heat pump outdoor unit, which also contributes to the overall efficiency of the system.
EVI technology thus makes heat pumps more versatile and cost-effective for use in different climates, especially in regions with cold winters.
