The design basis, suh as flow and return temperature, volume flow and differential pressure are maintained during operation. An effiient operation of the high-effiieny pump is ensured. Low return temperatures guarantee an effiient operation of the ondensing boiler. The heat or ooling output arrives where it is needed. There is no over- or undersupply. Wrong settings, suh as inrease of the flow temperature, exessive volume flows and resulting exessive return temperatures, undersupply of hydraulially underprivileged terminal units, but also oversizing or wrong irulation pump settings are avoided this way. Hydroni balaning means the optimum water distribution within the system whih is, for instane, ahieved by supplying the required volume flow to the radiator via presettable thermostati valves. This is onfirmed by many studies, suh as the Optimus study. Up to % of energy an be saved by arrying out the hydroni balaning desribed therein. The benefit/ost ratio of this low investment measure is exellent. Amortisation times of three to four years an be ahieved. 3 Automati / manual hydroni balaning Standard heating systems are equipped with thermostati valves whih are preset on the basis of a pipework alulation requiring knowledge of the installed pipework and the radiator volume flows (manual hydroni balaning). The layout of the pipework is often unknown and this makes a alulation almost impossible, however, Oventrop developed the thermostati valves with Q-Teh for an automati ontrol and hydroni balaning (automati hydroni balaning). The valves with Q-Teh an also be used for the hydroni balaning of new heating systems in whih the layout of the pipework is known. Advantages of automati hydroni balaning - automati adaptation to different operating onditions - redued alulation and planning effort - time- and ost-saving installation - fewer balaning valves required - hydroni balaning is maintained even if terminal units/setions of the system are ativated or inativated - balaned setions of the system are not hydraulially influened by installation extensions - system an be put into operating setion by setion during the onstrution period - effiient operation of high-effiieny pumps in any operating status - optimum alorifi value of ondensing boilers Advantages of hydroni balaning - energy savings due to an optimum energy distribution - inreased omfort due to a volume flow distribution aording to requirements - silent operation System house with Q-Teh Heating system without hydroni balaning 3 Heating system with hydroni balaning

3 Automati hydroni balaning with Q-Teh The new Oventrop Q-Teh for an automati flow ontrol in heating and ooling systems allows the adaptation of the volume flows aording to the requirements of the respetive terminal unit (e.g. radiator). The required volume flow through the terminal unit is determined by the heat load alulation and the hosen temperature differene. The volume flow is set diretly at the valve with Q-Teh and is automatially limited to the set value (illustr. ). This way, hydroni balaning of the system is arried out easily with the help of the valves with Q-Teh. Volume flow [%] Q = Constant Advantages of Q-Teh - even where high differential pressure variations our, for instane if terminal units or setions of the system are ativated or inativated, the volume flow is kept at a onstant level within the regulation toleranes - no speial body design required, the valve insert fits all standard Oventrop thermostati valve bodies manufatured sine 999 (M 30 x.5) - valve insert replaeable by using the speial tool Demo-Blo without draining the system - ideal for upgrading and refurbishment - wide adjustable flow range (0-70 l/h) - wide differential pressure ontrol range (max..5 bar) - silent in operation even with high differential pressures - the set volume flows are kept at a onstant level - differential pressure independent mode of operation to a large extent - onstant, high valve authority (a=) - infinitely adjustable presetting - fine graduated setting sale in l/h - set values visible from outside (without table) - easy setting by use of a presetting key whih prevents tampering to a large extent - valve insert with replaeable strainer Item no Simplified illustration of the valve insert with Q-Teh and presetting key using the example of the Series AQ Flow hart with exemplary values Differential pressure [mbar] 3

4 Thermostati valves Series AQ with standard valve insert Grafik Heizkörperanlage (aus neuem Katalog) The new thermostati valves of the Series AQ limit the volume flow to a preset value. A omplex alulation of the presetting values is no longer neessary. Only the required volume flows must be known. Control of the volume flow is arried out by the valve one the orret volume flow of the terminal unit has been set. This way, hydroni balaning of the system is arried out easy. The new valve of the Series AQ ombines a thermostati valve and a diaphragm ontrolled flow regulator. The nominal value is set by use of a presetting key and turning the handwheel. The funtions of the thermostati valve and the flow ontroller are integrated in a ompat valve insert whih an be replaed by using the speial tool Demo-Blo without draining the system. Many Oventrop produts are equipped with the valve insert. d e d e Valves Series AQ Item no.
