6 About the Danvent DV Danvent DV is designed as a modular air handling unit. Each function is placed into an air handling unit casing consisting of one or more modules. The modular functions can be configured for many different applications to make up the heart of any ventilation system. The modular construction is highly flexible, and the possibilities often only limited by the imagination. The flexibility makes it possible to combine the most optimized functions, e.g. the type of heat exchangers and fans with the highest efficiencies, combined with filters and coils with low pressure...

7 About the Danvent DV SystemairCAD calculates and optimizes the energy consumption of the air handling unit, and the calculated data are the basis for Eurovent certification and energy classification. SystemairCAD also calculates the Life Cycle Cost (LCC calculation) of the Danvent DV. To make it even more user-friendly, the program uses a number of combination examples, or basic variants, to which functions can be added or removed quickly and easily, until the ideal air handling unit is completely customised. Fully-dimensioned drawings, plus logical construction and presentation of...

14 Danvent DV Functions Dampers The dampers used in Danvent DV comply with EN 1751 sealing class 3. They have contra-rotating aerodynamically formed aluminium blades that ensure a low pressure loss when open. The blades are equipped with special rubber sealing strips between the blades themselves and the frame, to prevent air getting in. For very cold areas, the blades can also be insulated. The dampers ensure a long and trouble-free operation, as the blades are mounted on sturdy square profile shafts and service-free synthetic bearings with large bearing surfaces. A pivoting system placed...

15 Functions This system also ensures that the filter cells form a tight seal with the unit frame to comply with EN 1886. All seals are fixed to the unit and do not need replacement when installing new filters. Filter cells from all major filter manufacturers can be used in the DVF unit. Rotary Heat Exchanger DVC DVC is a rotary heat exchanger with a high level of efficiency that can also be used to transfer moisture from warm and humid extract air. This type of heat exchanger is the most efficient of the various heat exchanger systems and is also the most compact, due to its short length....

16 Danvent DV Functions Run-around Coil Heat Exchangers DVR DVR is a heat exchanger system where a mixture of water and glycol is circulated between a heating coil positioned in the supply airflow and a cooling coil positioned in the extract airflow. The transfer of heat takes place via a piped circuit that must be fitted after the unit is assembled. DVR heat exchangers have an efficiency of up to 55%. The effectiveness of the system is dependant on its construction and the volume and type of water/glycol mixture circulating between the coils. Run-around coil heat exchangers are used where...

17 be fitted on the connection pipe on the outside. A drip tray is fitted in the coil section to collect condensation. The drain outlet must be connected to a water trap with sufficient locking height. To eliminate the risk of water droplets being carried into the airflow, the DVK can be supplied with a built-in droplet eliminator. The coil is fully built-in the unit as standard, but comes also in a MAX version where the coil is wider than the standard unit width. This will reduce the air velocity.
