| Abstract |
The performance of two vertical-blade eliminators(V1, V2) and two horizontal- blade ones(H1, H2) for absorption chillers were tested in terms of pressure drop and refrigerant entrainment. The test was carried out using a wind tunnel with a cross section of 300mm×300mm. The pressure drop of four eliminators tested was found to be in the rage of 1.0～2.7mm H2O at the face velocity of 2m/s. In the refrigerant entrainment test the vertical- blade eliminators showed much better performance than the horizontal-blade ones. The horizontal-blade eliminators showed satisfactory results at the air velocity of 2m/s but exceeded the limit value at 3m/s. Since the cooling capacity of a machine is lowered by about 2.5% at the pressure drop of 1mm H2O, more researches are required to reduce the pressure drop in the eliminator. |
