Air Flow Areas of use of different flow types The mixed/displacement air flow developed by LTG and assumed into the VDI 3804 permits high cooling output at high thermal comfort. It can be implemented in any LTG device type with optimized air distributors. The above chart shows the areas of application of different flow forms that are essentially defined by thermal comfort. The ideal flow shape for the project-specific parameter cooling output and supply air flow rate can be implemented with different LTG air-water systems then. We perform optimization for special requirements within the scope of our engineering services. Products with mixed/displacement ventilation: HFV, HFG, VFC, VKB, HFB and FVD. 6 Empty Office Standard Office Densely Populated Office Meeting Room Comparison of conventional induction technology and SmartFlow technology The LTG System SmartFlow offers best comfort and energy consumption even under changing load stations. The ideal flow form is selected depending on required cooling output and fresh air volume. For this, the air nozzles are opened and the cold water valves are controlled. This ensures best comfort, acoustics and energy efficiency for any load case with a single device. Manual (different room use) or automatic (occupancy or CO2-controlled) regulation is possible. In contrast to conventional induction technology, this permits adjustment of cooling output and fresh air supply to the specific requirements. Products with LTG System SmartFlow: HDFsf, HFBsf and HFVsf. New: Power-off and easy parametrisation and set-up with LTG NFC app.

With LTG induction devices or fan coil units in combination with our highly inductive LDB linear diffusers permits sophisticated implementation of this comfortable room flow. Products with System Indivent: LHG and LVC. Appearance and room effect are essentially determined by the architecture. LTG SystemDesign permits different technical solutions for room air conditioning in different building areas under a visually consistent grid. Products with LTG SystemDesign: HFB, VKB, SKB, FVD and FVPpulse. LTG TransientFlow 20 years experience of research and application in the field of non-stationary (transient) systems. The extent to which the room is cooled is limited to ensure thermal comfort in the accessible area. A high cooling capacity means high volume flows and low supplied air temperatures at the unit s air outlet. This often results in draughts and discomfort. However, by getting away from the assumption of continuous, stationary air flows, we can make further optimisations possible. Thermal comfort can be increased considerably by using a pulsed flow, eddies that transport cold air along the ceiling, or through the cyclical introduction of supplied air. Naturally, no compromises have been made in terms of acoustic performance and energy efficiency. Instead, new benchmarks have been set. Products with TransientFlow: KFA, FVPpulse.

9 Induction Units Induction Induction Units Induction Technology - Comfortable and Efficient LTG induction units have been developed further continually since the first patent was registered by founder Dr. Albert Klein for an induction plant in The Induction Principle Air flowing through a nozzle forms a free jet. It induces the surrounding air layer along at its edges and thus enlarges the flowing air volume. This induction takes place within the induction device. A special construction entrains room air (secondary air) through a heat exchanger, where it is cooled or heated. Together with the fresh air (primary air) the supply air then returns to the room for a comfortable climate. LTG induction units of the latest generation are energy-efficient and can be operated and demandcontrolled with LTG SmartFlow technology.

Wall and Floor FVM, FVD and FVPpulse Decentralized Ventilation Units for Sill and Floor F V P pulse FVPpulse-V FVPpulse-B Time to breathe!

This pulsed, decentralized ventilation unit meets the aesthetic demands of architects as well as the wishes of planners, investors and operators: high indoor air quality coupled with outstanding

Unlike conventional facade-mounted ventilation units, FVPpulse uses a shared air duct for both the supplied and waste air, a single facade opening and only one fan.

This nonstationary ventilation results in the thorough mixing of the air in the room at low air velocities and high air volumes and consequently ensures an agreeable room climate.

29 Wall and Floor FVM, FVD and FVPpulse Decentralized Ventilation Units for Sill and Floor F V P pulse FVPpulse-V FVPpulse-B Time to breathe! Simple ventilation and air extraction with just one fan and one facade opening thanks to LTG s PulseVentilation system. This pulsed, decentralized ventilation unit meets the aesthetic demands of architects as well as the wishes of planners, investors and operators: high indoor air quality coupled with outstanding efficiency and minimum space requirements. The FVPpulse pulsed facade-mounted ventilation unit reproduces the natural movement of the air and allows buildings to breathe. Unlike conventional facade-mounted ventilation units, FVPpulse uses a shared air duct for both the supplied and waste air, a single facade opening and only one fan. Thanks to a system of dampers, it switches between the intake and outlet functions without causing any airstream short-circuits. This nonstationary ventilation results in the thorough mixing of the air in the room at low air velocities and high air volumes and consequently ensures an agreeable room climate. Important for architects and investors: FVPpulse units need fewer main components than conventional facade-mounted ventilation solutions and are more compact, while still offering the same level of performance. Benefits Non-stationary air flow: Air conditioning with highly effective ventilation and excellent thermal comfort thanks to a pulsed flow Just a single facade opening for supplied and waste air for the greatest possible freedom during facade design and exceptionally easy in-building installation without airstream short-circuits Highly economic reduced maintenance, servicing and operation costs by a single fan and only one outside air valve Extremely reliable operation thanks to innovative design and control concepts Uniform appearance thanks to LTG SystemDesign (floor-mounted unit) Engineering Services Decentralized Ventilation Units Fan Coil Units Induction Units 29
