Abstract

In this study, an innovative, evaporative condenser for residential refrigerator was introduced. A vapor compression cycle incorporating the proposed evaporative condenser was tested to evaluate the cycle performance. To allow for evaporative cooling, sheets of cloth were wrapped around condenser to suck the water from a water basin by capillary effect. The thermal properties at the different points of the refrigeration cycle were measured for typical operating conditions. The experimental results showed that the condenser temperature increases 0.45°C for each degree increase in evaporator temperature when the air velocity is 2.5m/s, and the ambient condition is 29°C and the relative humidity is 37.5%. Meanwhile, the condenser temperature increase is 0.88°C in the case of air velocity 1.1m/s and ambient conditions of 31°C and relative humidity of 47.1%. A theoretical model for the evaporative condenser was developed, and validated by experimental results. The theoretical model showed that the evaporative condenser can operate at a condensing temperature of 20C lower than that of the air-cooled condenser for heat flux of 150W/m2, and at air velocity 3m/s. The effect of the different parameters on the condenser temperature was studied too.
