According to Daikin, it achieves savings of up to 30% compared with conventional systems, extends equipment life and avoids temperature swings.<\/p>\n<h3>R32 refrigerant<\/h3>\n<p>It has a Global Warming Potential (GWP) 68% lower than R410A, is more efficient and easier to recycle and handle.<\/p>\n<h3>VRV systems<\/h3>\n<p>Variable refrigerant volume (VRV) systems precisely meet the thermal loads of each zone and integrate well into corporate, residential and commercial buildings.<\/p>\n<h3>Energy recovery ventilation<\/h3>\n<p>It renews indoor air while recovering up to 80% of the energy in the exhaust air, improving air quality without sacrificing efficiency. Indoor air quality is now a health standard in hospitals, offices, schools and homes.<\/p>\n<h3>Smart control<\/h3>\n<p>Apps and platforms make it possible to schedule equipment, monitor consumption in real time and set routines by schedule or occupancy. Some models learn usage patterns and adjust themselves.<\/p>\n<h2>Success story: modernizing an office building in Panama<\/h2>\n<p>In a corporate building under renovation, Airmax Group \u2014which had handled its maintenance for years\u2014 modernized the HVAC on two full floors.<\/p>\n<h3>The challenge<\/h3>\n<p>Maximize energy savings without sacrificing comfort or reliability, fitting into existing spaces for units and condensers, in a building that operated with cooling towers.<\/p>\n<h3>The solution<\/h3>\n<p>Water-cooled VRV systems and water source heat pumps (WSHP), integrated with the existing towers:<\/p>\n<ul>\n<li>157 indoor units including fan coils, cassettes and VRV mini splits.<\/li>\n<li>35 water-cooled condensing units.<\/li>\n<li>4 WSHP units for continuously operating areas.<\/li>\n<li>Integration of the cooling tower controls with the complex&#8217;s central system through Daikin iTouch Manager.<\/li>\n<\/ul>\n<p>The biggest challenge was integrating with the central control system, solved with direct technical support from the manufacturer.<\/p>\n<h3>Results<\/h3>\n<p>The client especially values being able to control all HVAC centrally. The solution lays the groundwork for a progressive reduction in energy and maintenance costs.<\/p>\n<h2>HVAC and building design<\/h2>\n<p>Efficiency does not depend only on equipment.
