Abstract

In conventional air-conditioning system, fresh air volume is always restricted to save energy, which Sacrifices indoor air quality to some level. However, removing the latent load of air by liquid Desiccant rather than by cooling is an alternative way of reducing energy consumption. Most of the research works on energy saving methods for air conditioning have focused on large chillers. Hence, this research work discusses energy conservation in a split air conditioning system, with a helical type intercooler that acts as a heat exchanger. The inter cooler used as a coolant like mixture of water and anti-freezing materials like ethylene glycol with different ratio. In this paper the ethylene glycol mixed with water in different ratio of 10:90, 20:80, 30:70, 40:60, and 50:50.Compare all the ratios optimum value 30:70 has been found. In this ratio the time taken for required cooling temperature from 28°C to 18°C was achieved by 1380 seconds. It is evident that the time taken for cooling by the modified system is 48.31% less than that of the existing split air conditioning system and also indirectly reduces global warming.
