Abstract EN

A study was conducted to development the evaporative cooler by adding magnetic water unit and heat exchanger .

A factorial experimental (2 × 2) with a complete randomized block design at the significant level 0.05 .

Added to evaporated cooler a water magnetized unit, it´s intensity 0.125 Tesla and finned heat exchanger which positioned in front of the air discharge slot .

The measured characteristics are in surrounding , cooler basin and outlet air from cooler and inlet to it and inlet water to the heat exchanger and outlet of it .

Relative humidity was measured in the surrounding in the air inlet to the heat exchanger and outlet of it .

The cooling efficiency was calculated (%) and relative humidity.

The results showed that the basin water temperature and outlet air of the cooler was significantly (p < 0.05) reduced by using magnetized water, as well as adding the heat exchanger to the cooler was reduced inlet temperature to the cooling space but when using magnetic water and heat exchanger together led to a significantly (p < 0.05) decreasing in the cooling space temperature and significantly (p < 0.05) increasing in cooling efficiency .
