Martin Passingham, DX product manager for Daikin UK, explores the importance of Lot 21 in the industry and how VRV IV+ is leading the way towards meeting the new European Directive for Energy related Products (ErP) requirements by improving the seasonal efficiency.
Seasonal efficiency measures the true energy efficiency of heating and cooling systems during a period of one year. Unlike older heating and cooling methodologies, seasonal efficiency tracks a system’s daily operations to include temperature fluctuations and standby periods. After one year, the seasonal efficiency data gives a more in-depth, reliable and true overview of a system’s actual energy consumption. This is important because more than 95% of the environmental impact of HVAC systems comes from indirect emissions, which is the measured energy consumption of the unit.
