Product catalog summary

Overview: The document provides comprehensive technical specifications and installation guidelines for LTG Aktiengesellschaft's decentralized facade ventilation units, specifically the Univentr Type FVS series. These units are designed for indoor installation below the ceiling, suitable for environments such as conference rooms and schools.

Specifications: The FVS units are compact air conditioning systems that facilitate decentralized ventilation directly via the facade. They include components such as a weather protection grille, ventilation module with sound and heat insulation, supply and exhaust air fans, and a heat recovery system. The units are designed to accommodate 20 to 30 people in a ventilated area of 60 to 80 m².

Advantages: Key benefits include a compact design, easy installation, high thermal comfort, energy-efficient operation, and high sanitation standards. The units offer high outside air flow rates and low sound pressure levels, with efficient heat recovery up to 85%.

Functional Principle: The units connect to an outside air module with a weather protection grille, facilitating the separation of exit and outside air streams. They feature a combined outside air/secondary air damper for efficient air mixing and temperature control, ensuring energy-efficient heating and cooling.

Installation: The units can be installed visibly below the ceiling or integrated into ceiling paneling. They require specific installation dimensions and configurations, including the use of linear or swirl diffusers for air distribution.

Design and Standards: The units meet various DIN standards for dimensions, tolerances, and surface finishes. They are designed for indoor air climate applications and are powder-coated for durability.

Control and Operation: The units feature electronic controls for start-up and shut-down, supply air temperature control, and usage-dependent ventilation. They can be operated manually or via sensors and are compatible with building management systems.

Technical Data: Detailed sound power levels (LwA) for different operating modes and configurations are provided, including the use of a splitter attenuator. Power consumption (Pel) is specified for various modes. The sound power levels are measured at different points, such as the sound absorber outlet and the weather protection grille.

Control System: The FVS units feature a convenience control type DKR 6000, optimized for energy consumption and indoor air quality. The control system includes automatic mode activation based on CO2 levels, with inputs for different ventilation modes (100%, 50%, nocturnal, and forced ventilation). The system is factory-programmed and includes a CO2 sensor for automatic operation.

Installation Requirements: The document outlines the installation requirements, including the integration of the weather protection grille, adapter ducts, and inspection openings. It emphasizes the importance of air-tight separation of outside and exit air ducts and provides guidelines for connecting the unit to the facade.

Additional Features: The units include a condensate drainage system, emergency shutoff mechanisms, and malfunction indicators. The control system allows for parametrization via an optional HMI module, enabling adjustments to operating modes and set-points.

Conclusion: The LTG Decentralized Facade Ventilation Units Univentr Type FVS-S are designed for efficient and flexible ventilation solutions, with detailed specifications and control options to optimize performance and energy efficiency.

General Description: The document describes a decentralized facade ventilation unit, Univent® Type FVS-S/O, designed for visible installation with an integrated linear diffuser. It features high-efficiency sound absorption for supply and exhaust air, direct facade connection, and weather protection grilles. The unit supports decentralized ventilation with heat recovery and controllable secondary air mode, maintaining a minimum supply air temperature of 17°C year-round.

Specifications: The unit includes a twin-wall casing of galvanized sheet steel with 40 mm mineral wool insulation. It is designed for free cooling through supply air temperature control and features low-noise centrifugal fans with energy-efficient EC motors. The unit meets SFP Class 1 requirements and includes fine filters for outside and exhaust air.

Control and Operation: The control system is integrated, offering four operating modes and potential-free contact switching. It includes supply air temperature control to prevent freezing and supports nocturnal ventilation. The system can connect to an air cooler and features an Ethernet interface for parameter adjustments.

Installation and Maintenance: The unit is suitable for plug-in installation in school rooms, with easy connection to the outer wall. It is factory-wired and tested, with a modular design for flexibility. Maintenance access is provided for filters, actuators, and condensate trays.

Dimensions and Accessories: The unit measures 500 mm in height, 1050 mm in width, and 4500 mm in length. Accessories include service tools, remote switching units, duct adapters, CO2 sensors, and interfaces for control overriding. The document emphasizes the need for proper electrical installation verification before commissioning.
