晨怡热管 2009-1-26 14:48:17

The emission figures shown in the tables below are based on a low pressure hot water supply at 74º C (165º F) with the surrounding air at a temperature of 18.3º C (65º F) and the water velocity of 0.061 m/sec (0.2 ft/sec).
These emission figures are based on results obtained at the Heating and Ventilation Research
Association (H.V.R.A.) Laboratories for steel gilled tubes supplied with low pressure hot water and installed in still air against a cold wall.
Emission in Watts per metre with low pressure hot water
55.7º C temperature difference and a water velocity of 0.061m/sec (0.2 ft/sec)
