Measuring the Energy Efficiency of Evaporative Systems Through a New Index—EvaCOP

Evaporative systems are probably the oldest technology for thermal comfort. However, they still an essential in food industry, environments comfort, and even cooling data centers. Standards have been improved to compare energy efficiency of this type equipment. Using AHRI concepts with temperature from 29 most populous cities world, EvaCOP index was created temperatures that easier simulate than current parameters. The parameters were tested a laboratory located Curitiba (Brazil). values 45.58 25.77 W/W found calculation two different simulated equipment compared compression cycle efficient machines is around 6.29 W/W.
