German clean tech company InvenSor presented a new adsorption chiller at the 2015 Hannover Messe with a cooling capacity three times higher than the previous model.
The LTC 30 e plus (power output range 10-35 kW) went on show last month for the very first time. Speaking at the event, InvenSor managing director, Sören Paulußen, said it is the highest capacity and most efficient new member of the product family.
"This product is a small revolution in the field of thermal cooling in Europe. We increased all of the technologically relevant performance figures while at the same making the technology even more efficient," he said .
According to figures for 2014 published by Germany's Federal Ministry for the Environment, 14 per cent of Germany's electricity demand and approximately five per cent of the country's direct and indirect greenhouse gas emissions can be attributed to cooling systems.
Due to their efficiency and by using water as the refrigerant, adsorption cooling systems can reverse this trend. With a maximum thermal coefficient of performance (COP) of 0.75 - describing the efficiency of the use of heat for cooling - and an outstanding maximum energy efficiency ratio (EER) of 33, the new InvenSor LTC 30 e plus is one of the most efficient chillers on the market.
Paulußen said compared to standard products available, the significantly increased EER value is of particular note, especially considering the integrated pumps inside the LTC 30 e plus.
He said that compared to conventional systems, the new InvenSor system achieves an increase in EER by a factor between 5 and 20. This is equal to electricity savings of 80-95 per cent. The LTC 30 e has a maximum cooling capacity of 35 kW.
Compared to systems with lower capacities, in large-scale projects, the specific costs per kW cooling capacity can be reduced by approximately one third, according to InvenSor. A complete, ready-to-operate hydraulic unit is integrated into the new chiller, with high-efficiency pumps, mixers, valves, and extensive sensor equipment.
All cycles for hot water supply, cooling distribution, and recooling can be directly and quickly attached to the system. As with all InvenSor cooling systems, the LTC 30 series is also equipped with the ActiVac automatic pressure optimization system, which was developed in-house – keeping service requirements to a bare minimum.
Maintenance is reduced to simple tasks related to air and water cycles. The cooling generator itself is maintenance-free.
