Passive chilled beam with 2-pipe heat exchanger for ceiling installation, either freely suspended or above an open cell ceiling Optional equipment and accessories Application Special characteristics Nominal sizes Variants Construction Attachments Useful additions Materials and surfaces Standards and guidelines Maintenance Functional description Passive chilled beams are used to dissipate high heat loads. Warm room air rises due to thermal buoyancy, is cooled by the heat exchanger, then slowly flows downwards again to the occupied zone. The quick sizing table lists standard cooling capacities. For other operating points you may use the Easy Product Finder design software. Quick sizing – nominal cooling capacity [W] to EN 14518 Passive chilled beams of Type PKV, without frame for installation above open cell ceilings, or with frame for freely suspended installation, suitable for the dissipation of high heat loads. Special characteristics Materials and surfaces Construction Technical data This specification text describes the general properties of the product. Texts for variants can be generated with our Easy Product Finder design programme. Installation and commissioning Nomenclature tWV [C°] Water flow temperature – cooling/heating tR [C°] Room temperature tAN [C°] Secondary air intake temperature Qtot [W] Thermal output – total QW [W] Thermal output – water side, cooling/heating VW [l/h] Water flow rate – cooling/heating ∆tW [K] Temperature difference – water ∆pW [kPa] Water-side pressure loss ∆tRWV = tWV - tR [K] Difference between water flow temperature and room temperature ∆tWm-Ref [K] Difference between mean water temperature and reference temperature LN [mm] Nominal length Convection Passive chilled beams remove the heat from the room air and transfer it via a heat exchanger to the water (transport medium). More than 90 % of the heat are transferred through convection. As the air passes over the surfaces of the heat exchanger, its temperature decreases while its density increases as a consequence, hence accelerating the downward airflow. The air flows straight down from the top to the bottom of the unit. This further increases the downward airflow (stack effect) and hence the cooling output. Heat exchanger The maximum water-side operating pressure for all heat exchangers is 6 bar. The maximum water flow temperature (heating circuit) for all heat exchangers is 75 °C; if flexible hoses are used, the water flow temperature should not exceed 55 °C. Units for other pressures and temperatures are available on request. The water flow temperature (cooling circuit) should be at least 16 °C such that it does not permanently fall below the dew point. For units with a condensate drip tray the water flow temperature may be reduced to 15 °C. Heat exchanger as 2-pipe system Air-water systems with a 2-pipe heat exchanger may be used for either heating or cooling. In changeover mode it is possible to use all units within a water circuit exclusively for cooling in summer and exclusively for heating in winter.

Jednostavno, precizno i učinkovito Tri optimirane kontrolne jedinice odlikuju se najvišom kvalitetom, jednostavnim instaliranjem i preciznim radom. Projektiranje tehničkih usluga u građevinarstvu složen je zadatak. Očekivanja vlasnika često su jednaka: ekološka i ekonomska održivost uz istodobno visoku udobnost i male troškove ulaganja. Ne postoje međutim dva potpuno jednaka objekta ‑ različiti tipovi građevina i njihovo korištenje, bilo da se radi o novoj gradnji ili obnovi, zahtijevaju individualne koncepte. Pronađite najbolja klimatizacijska i ventilacijska rješenja za svoje objekte! Ovdje možete saznati više o sljedećim temama: U kupovini Uredi Laboratoriji Hoteli Zračne luke Škole, centri za dnevnu skrb i druge obrazovne ustanove Bolnice Stadioni Muzeji Čisti zrak Naši priručnici za projektiranje pomažu vam u individualiziranom projektiranju klimatizacijskih sustava.
