Ventilation, Cooling and Heating of Halls – Now Fully Decentralized

Hoval creates space and combines its decentralized ventilation system with decentralized heat pumps, providing designers with a new freedom in designing HVAC solutions for halls and warehouses which are heated in the winter and cooled in the summer. Rooms for equipment become unnecessary, the amount of pipelines is reduced considerably, and as a result, maintenance and operating costs are lower.

Hoval is subdividing – literally: “When we are talking about decentralized systems, we no longer mean just RoofVent® and TopVent®, but also decentralized heat pumps”, says Georg Eberharter, Product Manager of Hoval ventilation systems. The result is a solution that saves space.

Saving space means saving money. When they are combined into a fully decentralized solutions, systems of cold and hot water become unnecessary. This means that equipment rooms no longer need to be included in the plans of new halls. Commerce or industry get precious additional space.



No more gaps and connections through walls

Air canals, heating pipes and the substantially more expensive cold-water pipes are no longer there. This reduces design costs, and installers no longer need to fit pipes through the walls and concrete structures. The full installation is fitted on the roof. The expensive anti-diffusion heat insulation for cold-water pipes is no longer necessary. The interior of the hall looks neater and is fully usable.

Lower overall costs

Lower overall costs result in lower operating costs: thanks to the optimal air distribution, the decentralized system, which consists of a RoofVent® device and a TopVent® device and their heat pumps have minimal losses in air inflow and outflow pressure drops, as well as minimal losses of heat compared to standard centralized systems. On its part, the air/air heat pump provides high efficiency with standard temperature demands. The product manager of Hoval ventilation system is convinced that the efficiency exceeds that of boilers. The data from several test installations in Austria show that the facilities which use a fully decentralized system have reduced their operating costs by 36% compared to the facilities which use a centralized gas boiler room.

What’s more, the heat pump uses renewable energy. CO2 emissions are reduced to a minimum – especially compared to centralized heating solutions which use fossil fuels. On top of that, there is no need for import and consumption of fossil fuels.

The total costs of the life cycle and the emissions are kept within acceptable limits. Among other things, this is also a result of the modern regulation platform, because RoofVent® RP and TopVent® TP units communicate with their heat pumps, making for an integral, inseparable system. Another advantage of this system is that each of its parts is delivered by a single supplier, which simplifies the designing, the organization of the production and the subsequent maintenance. To cite Georg Eberharter: “We have combined the advantages of our decentralized ventilation units and heat pumps”. Modern designers will certainly follow the example of the test facilities in Austria, which have reduced the costs of ventilation, cooling and heating by more than a third.
