Abstract:

Normally air cooled and water cooled condensers are used separately according to their requirements. For small capacity refrigeration system air cooled condensers are used and for larger units water cooled condensers are used. In hot climatic condition the air cooled condensers does not provide the required output temperature. To get the required level, the power input for the system got increased. For that this air cum evaporative condensing unit is implemented. In this a wet pad arrangement is designed. There is a water flow provided in the wet pad. While passing the atmospheric air through the wet pad, the water present in that got vapourized and it mixes with the flowing air. While this moisture air is made to flow over the condenser tubes, the temperature of the condenser can be reduced to some extent. This result in the performance of the system. In the absence of water flow the system works normally as an air cooled condenser.
