Consumption Criteria and Energy Labeling of Wet Cooling Towers in Iran

Increasing concerns about global warming and environmental pollution control has pushed the relevant organizations to set regulations and to develop programs for energy saving. In addition, for many high energy using appliances, energy labeling provides the end user with important data to select energy-efficient equipments and encourage the manufacturers to enhance the performance of their productions. In this research, a new energy-saving program for wet cooling towers has been developed. Considering a thermo-hydraulic analysis, a novel Energy Index (IE) has been extracted which takes all aspects of the problem into account. The present index can be used as a proper criterion for energy consumption of wet cooling towers. The required parameters are measured using national and international standards. Based on the experimental-statistical study of a comprehensive range of products, the quantities of acceptable energy consumption criterion and energy rating have been extracted for different types of cooling towers. Administration of such program may lead to considerable energy saving in cooling systems which have major economical and environmental advantages especially in large industries.
