What is EVI in Heat Pumps?
In the air‑source heat pump industry, “EVI” is a term frequently mentioned but not always fully understood. When more and more heat pump products claim to deliver stable heating at extreme temperatures as low as -25°C or even -35°C, the core technology behind that claim is EVI – Enhanced Vapor Injection. Without EVI, large‑scale adoption of air‑source heat pumps in frigid northern regions would be almost impossible.
Against the backdrop of global carbon neutrality targets, heat pumps – as the key technology for efficiently converting electricity into heat – are experiencing unprecedented growth. However, the well‑known “Achilles’ heel” of conventional air‑source heat pumps – severe capacity degradation and plummeting efficiency at low temperatures – has long troubled the industry. It is against this background that EVI technology, with its revolutionary vapour‑injection approach, has become an indispensable pillar of high‑end heat pump products. As a technology leader in the global heat pump arena, Flamingo has deeply integrated EVI into its diverse product portfolio, delivering complete solutions for commercial, industrial and residential applications, and creating a new pathway for clean heating in cold climates.
