Study and Optimization of Performance Parameters of Air- Conditioner by Using Waste Water of Water-Cooler

Reduction of energy consumption and rise of cooling is a major concern in the air conditioning system especially in the area with very hot weather conditions. In hot weather conditions, the air conditioner takes more electrical power consumption to bring the comfort in specified area. In many Middle East countries, the atmospheric temperature approaches 40°C to 50°C or sometimes higher. During these temperature conditions, the air conditioner compressor continuously works and consumes more electrical power. On the other hand, the waste water of water cooler is drained out freely in atmosphere. This waste water generally leaves at its minimum to maximum temperature which is shear wastage of energy. These two areas are identified where the compressor is working continuously due to more temperature of condenser environment. To extract the energy from the wastage, a combination of air conditioner and water cooler is purposed in the present investigation. The waste water of water cooler can be sprayed on the condenser of air conditioner so that efficiency of air conditioner can be increased. To investigate the effect, Drip Rate, Drip Position and Fan Speed were taken as process parameters whereas Amperage, Sucking Temperature and Humidity were taken as response parameters. In this experiment, L9 orthogonal array was used. Results show that the effect of running amperage is found to affect the performance significantly & its low value for optimum performance is recommended.
