Indoor climate systems. Decentralised solutions for heating, cooling and ventilation
Decentralised indoor climate systems. Simple and reliable solutions for the right indoor climate
For tall, single-storey halls up to 25 metres in height, Hoval indoor climate systems offer an efficient solution for heating, cooling, and ventilation.
Instead of a centralised system with an extensive network of air ducts, several decentralised units work together as an intelligent integrated system. The units are positioned where the output is required. This results in a streamlined system structure that requires minimal installation effort and offers a high degree of flexibility.
The patented air distribution system ensures uniform temperatures without stratification. It creates precisely the temperatures required within the hall. Even different temperature zones within a single hall can be easily achieved.
Planning and implementation are also relatively straightforward. At Hoval, you have a single point of contact for your project, reducing coordination effort and saving time, from planning to installation and commissioning.
Simple: in planning, implementation and operation
We aim to create simple and practical system solutions for our customers. A decentralised indoor climate system ensures straightforward coordination, planning and implementation, as well as simple operation.
Reliable: consistent, even temperatures in your hall
Decentralised indoor climate systems ensure safe and reliable operation, without compromise. They maintain a constant indoor climate, consistent temperatures and high air quality.
An investment in the future that pays off
Decentralised indoor climate systems offer innovative, sustainable solutions for heating, cooling and ventilation: long service life, low energy consumption, low costs and maximum efficiency.
“We’re thrilled to see the benefits that the solution we implemented has brought for our customer – and it required relatively little effort on our part.”
How the decentralised Hoval indoor climate system works
Hoval indoor climate systems consist of a range of units that can be freely combined for heating, cooling and ventilation.
The units are arranged to suit the hall’s intended use and layout and are networked by means of an integrated control system to form a single intelligent system.
Control algorithms, developed over many years, coordinate the interaction of all components and ensure that the exact desired climate conditions are achieved.
The system is complemented by the patented air distribution system, which prevents temperature stratification and thereby reduces energy losses.
As a result, This ensures that the required temperature is maintained throughout the hall. In addition, different temperature zones can be created within the same hall easily and precisely.
Consistent temperatures without draughts or temperature stratification
The Air-Injector ensures even air distribution without temperature stratification. Depending on whether the system is heating or cooling, it directs the air vertically or horizontally:
- Heating operation (left): The supply air is warmer than the room air and therefore lighter. The vertical airflow ensures that the heat reaches where it is needed.
- Cooling operation (right): The incoming air is colder than the room air and sinks downwards. To prevent draughts, it is fed in horizontally.
By ensuring even air distribution and preventing draughts, the Air-Injector significantly improves comfort. Optimised air distribution also helps to reduce energy losses through the hall roof.
Heat pumps: the technology of the future
All models in our Hoval indoor climate systems are available with energy-efficient heat pumps, allowing large industrial halls to be ventilated, heated and cooled efficiently.
Each ventilation unit has its own heat pump unit and is therefore independent of a central heating and cooling system.
If a piece of equipment fails – whether due to maintenance work or a fault – the other pieces of equipment can temporarily compensate for this problem, ensuring a high level of operational reliability for the entire system.
Decentralised indoor climate system: simple and reliable
RoofVent ventilation units: with energy recovery
Hoval RoofVent ventilation units combine heating, cooling and ventilation in a single unit.
The decentralised units are installed directly on the hall roof and, thanks to heat recovery and a patented air distribution system, ensure high energy efficiency and uniform temperatures without stratification.
For a particularly energy-efficient and sustainable indoor climate solution, RoofVent modules can be combined with heat pumps to form a high-performance integrated system.
Thanks to its flexible unit configuration, RoofVent is suitable for a wide range of requirements in production, logistics and industrial buildings.
TopVent C/S roof-mounted units: for uninterrupted hall operations
The Hoval TopVent C/S roof-mounted units offer the same benefits as the tried-and-tested TopVent recirculation units for energy-efficient heating and cooling of high-ceilinged halls.
Most of the unit is located above the roof, thereby preserving more usable space inside the hall. At the same time, access for servicing and maintenance work is through the roof so that day-to-day operations in the hall are not usually disrupted.
The patented air distribution system guarantees uniform temperatures without temperature stratification and creates comfortable conditions even in halls with high ceilings.
For a particularly energy-efficient and sustainable indoor climate solution, TopVent C/S units can be combined with heat pumps, providing a cost-effective solution for a wide range of requirements in production, logistics and commercial premises.
TopVent supply air and recirculation units
Hoval TopVent recirculation units have been specially developed for heating and cooling high-ceilinged halls. They make primary use of the existing air in the hall and, thanks to their patented air distribution system, ensure uniform temperatures without temperature stratification.
Thanks to their long range, only a few units are often needed to air-condition large hall areas.
For a particularly energy-efficient and sustainable indoor climate solution, TopVent units can be combined with heat pumps.
Thanks to the range of different models available, the TopVent is suitable for a wide variety of requirements, from production, logistics and commercial premises right through to supermarkets.
ProcessVent compact units:
Ventilation, heating and cooling with highly efficient energy rec overy from process extract air.
Hoval ProcessVent units have been specially developed for workshops with process-related extract air, such as those containing enclosed machine tools or welding systems.
When used in conjunction with an extract air purification system, they ensure clean air and use the energy in the process extract air to heat the fresh air, which in turn enables a significant reduction in energy consumption and heating costs.
The decentralised units are installed directly alongside the machine groups and, if required, can also provide heating and cooling for the hall area, creating a cost-effective solution for air exchange, energy recovery and indoor climate control, all within a single system.
