TVZ · TVA TVM TVR TVRK TVJ/TVT Design and Areas of Application 2 Volume Flow Control Terminal Units for VAV Systems The VARYCONTROL VAV terminal units are designed for variable air volume flow systems (VAV). The types are selected according to various project-specific criteria: Selection Criterion Terminal Unit Type System Supply air Type Single duct TVZ/TVS/TVR/TVJ/TVT Dual duct TVM Extract air TVA/TVR(K)/TVJ/TVT By acoustic criteria Very high TVZD + TS TVAD + TS TVMD + TS TVJD/TVTD + TX High criteria TVZ/TVA/TVM Low criteria TVR/TVJ/TVT Reduction in duct velocity TVZ/TVA/TVS/TVM Low installation height TVR/TVJ/TVT Chemical resistance Coating TVR-P1/TVJ-P1 Stainless steel TVR-A2 plastic TVRK Volume flow ranges 15 to 1680 l/s TVZ/TVA/TVS 10 to 1680 l/s TVR/TVRK 40 to 615 l/s TVM 45 to 10100 l/s TVJ/TVT The volume flow is controlled by a volume flow controller which uses pneumatic or electrical energy. These controllers and the associated measurement and activating elements are integral parts of the volume flow control terminal unit. The overall design of the air conditioning system results in the VAV terminal unit being the connecting element between the system and the room, with the following functions: • to adjust the volume flow within specified tolerances irrespective of duct pressure • as an auxiliary parameter for the room temperature controller, to maintain a constant room temperature. To achieve the correct control strategy, various tasks must be noted when planning volume flow control systems. The system designer, contractor, manufacturer of the control system and Trox must collaborate and the exchange of information is essential.
