Cooling system cool waveR - Selection data LTG chilled beam with oscillating fan is compact, ceiling-mounted unit which cools the air in a room by convection, making use of the recirculating principle. For reasons of hygiene, it should not be used for dehumidification. The lowest water supply temperature for operation without condensation essentially depends on the humidity of the air and may be 1- 2 K below the dew point of the ambient air. With the cooling fan inoperative, however, a water supply temperature as low as this may cause condensation to form on the heat exchanger plates, similar...

Cooling system cool waveR - Power measuring method Marginal conditions: - determination of room temperature tR at a height of 1.1 m - uniformely distributed heat sources (Q) in the room. Dimensioning The selection may be realized by one of the two methods: 1. Determination of the water inlet temperature and the water flow rate: The cooling capacity diagram (page 6 and 7) will then state the specific cooling capacity Qk/∆t. 2. Determination of the required temperature difference ∆tW (water inlet minus water outlet temp.): The cooling capacity diagram (page 6 and 7) will then indicate the specific...
