Experimental investigation of refrigeration efficiency by domestic fan with cooling pipes

The supply of required cooling energy for building and industrial applications, along with simultaneous efforts to reduce environmental pollution and also reduce electricity consumption and related costs, are a concern that has been considered by researchers for years. Required cold load in most parts of Iran is higher than for heat load. In hot and humid areas where we have to use compression refrigeration systems with high power consumption, it seems more necessary to find alternative methods. In this research, a new design in the form of a cold water cycle in a copper pipe that can be installed on domestic fans has been proposed which can also significantly reduce power consumption and be able to replace the compression cooler in times of moderate temperature. The results showed that in times of moderate heat, this alternative system can be used and create similar cooling conditions with air conditioners and cusses a reduction up to 90% in electricity consumption. Also, the return on investment in this project was calculated for about one year.
