Energy Efficiency Improvement of the Split Air Conditioner Through Condensate Assisted Evaporative Cooling

The overwhelming evidence of global warming caused by human activities documents both contemporary impacts on human life but also extraordinary future risks are also assisted with it. Accretion of global temperatures engenders the extensive use of air conditioning devices to make the surrounding livable in the summer season. Energy consumption for air conditioning is also palpable by the evidence that this industry is the 2nd largest power-consuming sector in the consumer field. High temperatures also affect the performance of the air conditioning system by decreasing their energy efficiency ratio (EER) and cooling capacity (Q_C). Modifications are made in such a way to lower down the temperature of the surrounding by the use of a honeycomb wet pad which uses evaporative cooling with condensate of the indoor side. Experiments were made to observe the difference in performance efficiency, with modification and sans modification, by operating separately at 40–50 °C temperatures. Results were evident that condensate assisted evaporative cooling shows improvement in cooling capacity by 19% and a reduction in power consumption (P) by 13% as compare to the conventional system. A huge increase in the energy efficiency ratio of 36% was observed with the use of the modified system. The things used for the modification are cheaper and easily available in the market.
