Using Lorentz Cycle with R407E.C., an alternative R-22 refrigerant, this system is equipped with multi-function that responds to cooling energy infinitely by using hybrid pre-cooling. It is suitable for buildings and businesses that consume a lot of cooling heat, such as IT businesses and data centers, and it uses hybrid heat sources such as geothermal, seawater heat, water heat, and waste heat, so we will apply eco-friendly systems.
