General Features Description The IHK ceiling-mounted induction terminal units are used in air-water systems to provide a high level of comfort in interior environments with high internal thermal loads in cooling operation. The IHK units are recommended for bulkhead and suspended ceiling installation. Ideal for hotel guest rooms and hospitals. The units include the following components: .Primary air plenum, with one round duct connections for priIHK mary air inlet and a distribution of small nozzles with alternative settings. Hot or chilled water (two-pipe installation) or hot and chilled water...

General Features Advantages The IHK ceiling-mounted induction units are terminal units for central air conditioning installations that provide solutions to meet the needs of the following: .Ventilation achieved with primary air .Cooling, based on the primary air itself and the water circulation coil .Heating, based on a water circulation coil .Control. Possibility of individual or combined unit control by room or area, using control and regulation valves in the unit to adjust the water volume and room thermostats .Air diffusion based on a grille that ensure effective air diffusion. In addition...

Series IHK IHK-F The IHK-F ceiling-mounted induction terminal unit from Koolair are specifically designed for use in hotels and hospitals, where the area to be cooled has not suspended ceiling and therefore their installation is in the hall annex. The one-way horizontal supply air and the return is made in the same grille. The cooling and heating powert are 8% lower than the IHK model whose values found in pages from 11 to 14.

Series IHK IHK-V The IHK-V induction terminal unit from Koolair are specifically designed for installation along the perimeter zones. The unit is installed against the facade, it is not required space on the floor, ceiling or corridor. This model is available with condensation tray. The cooling and heating powert are equals the IHK model whose values found in pages from 11 to 14.

Series IHK Installation The IHK units include a series of hanging brackets on the two upper longitudinal sides of the units, as shown in the following photographs. There are two brackets per side. These brackets have a slot hole to hold a 06 mm threaded rod, which is first attached to the ceiling slab to hang the unit. The unit can be fixed directly to the ceiling surface or suspended using threaded drop rods.

Volume Regulation and Control Components - Air Usually, the constant flow system is used most often to distribute primary air to the induction terminal units. To ensure that the installation is correctly balanced, an extremely important aspect for proper operation of the active chilled beam, Koolair RCCK mechanical self-regulators are used because they ensure self-balancing of the installation. CRC-M manual volume control dampers can be selected but require manual balancing of the installation. Ductwork pressure dampers (RVV) can be used to ensure the specific inlet pressure in each beam. Mechanical...
