EVALUATION OF EXISTING COOLING SYSTEMS FOR REDUCING COOLING POWER CONSUMPTION

Abstract

As energy costs rise, and the public becomes more aware of the environmental damage arising from current energy use patterns, more people are looking into passive as a way of reducing the amount of energy used. In India, just as much energy, if not more, may be used for cooling in summer. Thus, a properly designed building in India should be designed to require a minimum amount of energy for cooling in the summer. This work was designed to estimate the cooling load power consumption during the summer in the month of July. The actual cooling load for cooling systems of a seminar hall with various applications was recorded during the peak load period of the year (July). The records were used for estimating the total power consumption of the cooling systems in this region. According to this estimation, the cooling systems power consumption in this region accounted for more than 60% of the total power consumption during the peak load period of the year. A computer program was developed for simulating the effect of various parameters on cooling load of the building. According to the simulation results, use of double glazed windows, light colored walls and roofs, and insulated walls and roofs can reduce the cooling load of the buildings more than 15%.
