Summary

Today, with rising energy demand, it is imperative to focus on the implementation of energy efficient solutions for sustainable growth. In a tropical country like India, HVAC systems are the biggest energy guzzlers among the utility loads. With peak summer temperatures soaring beyond 35°-45°C, HVAC systems may account for more than 65%-70% of the total electrical demand. When peak summer temperatures are very high, the air conditioning system has to work harder to provide a comfortable indoor environment, fighting harsh outside conditions. The load on the compressor of the chiller is higher and consequently, it draws more energy to provide the desired cooling. However, it is interesting to observe that when the outside temperatures are cooler (say during winters), the same HVAC system experiences a lesser load on the compressor and consumes less energy. The observation can be validated if the summer and winter electricity bills of a given building are compared.
