Economical, ecological, efficient
Sustainability means achieving economic results with ecological solutions that are profitable. That is Konvekta.
ECONOMICAL
Konvekta systems offer proven economic advantages. In the preliminary design, the Konvekta system simulation provides exact energy data by using precise mathematical models, which can be used as a basis for capital spending decisions and for applications for subsidies. The high efficiency of the systems guarantees return on investment. This makes short term return-of-investment achievable. Cumulative annual savings over the entire service life of a system is a key advantage. For example, the Klinikum München-Bogenhausen system [Munich-Bogenhausen Hospital] achieves a verifiable annual efficiency of 86.3%, which saves more than 3,200,000 kg CO2 per year and energy costs of almost 500,000 euros (based on 2012 energy costs). This corresponds to a risk-free return on investment of almost 28%. Such high values are achieved by:
- Exact optimization of the net annual energy recovery based on the daily conditions of use and climatic conditions on site
- An integral design that allows initial costs and operating expenses to be reduced in other trades
- Precise operational optimization that accurately recalibrates the system based on actual measured data
- Highly efficient heat exchangers that deliver the highest performance in a very compact way due to their unique design using the counterflow principle
- System control that continuously maximizes energy gain based on current conditions
- Efficient optimization for system options such as multi-functional high-performance energy recovery systems and composite energy recovery systems.
ECOLOGICAL
Konvekta systems offer strong ecological advantages.
- Depending on the operating conditions, Konvekta systems achieve verifiable annual efficiencies of over 90%, so that less than 10% of the energy requirement comes from traditional heat sources. Individual systems are able to save more than 9,000 tons of CO2 per year. Konvekta systems in operation currently save more than 260,000 tons of CO2 per year. This corresponds to 30,000 car journeys around the world every year.
- Plate heat exchangers can be used to introduce cooling and heating sources into the water/glycol circuit. This allows the outside air to be heated or cooled with only 1 coil in the supply air handler and minimizes the air pressure drop. Ideally, existing energy sources are used for this purpose, such as in a free-cooling application.
- By incorporating adiabatic cooling in the exhaust air, cooling is added to the system very efficiently without the use of a chiller.
- With the Konvekta Zero Emission Energy Recovery System, buildings can be air conditioned entirely without the use of fossil fuels.
Together with our customers and partners, we are making a significant contribution to a better environment.
EFFICIENT
The basis for advantages of Konvekta systems lies in the selection of high-quality components and fabrication. Thus, annual utilization rates of up to over 90% can be achieved.
- The ERS heat exchangers, design and simulation Syskon software, as well as the controller software are manufactured and continuously developed at Konvekta’s headquarters in Switzerland. Thus, Konvekta can guarantee that all system components are exactly matched to each other and show the highest efficiency in operation.
- The Konvekta software simulation and the Konvekta Controller always use the same system design. This not only allows efficient and flexible response to changes throughout the design process, but also ensures that when the system is in operation the controller functions based on the same design as the simulation used.
- The ERS heat exchangers are based on a unique design with headers on both sides designed for almost perfect countercurrent flow. This makes the units exceptionally compact and very efficient.
- Taking into account the day-to-day use of the building and the meteorological data of the ERS site, the system is optimized for efficiency during the design phase. The Digital Twin approach allows system adjustments to be quickly calculated and easily compared with each other.
- Through fine calibration during the optimization phase, the actual recorded operating data for an entire year is utilized to increase efficiency. This ensures that the ERS operates efficiently not only at the time of commissioning, but in all conditions throughout the year.
- The Konvekta Controller continuously optimizes the overall system performance based on actual measured values. At any point in time, the theoretical maximum energy recovery is calculated. Through this comparative value, the system efficiency can be shown at any time.
- System data is continuously collected, recorded and displayed. Historical and current data are used for problem analysis. Performance deviations can be quickly identified and remedied.
