| چکیده | ||
| The paper presents study the factors that can improve the performance of an activated carbon/methanol intermittent solar adsorption icemarker. That uses an adsorption tube collector for cooling, in which solar energy can be directly absorbed. Effect of some important parameters, such as amount 8of methanol, condenser temperat., initial and peak collector temperat., on the system performances were investigated. The amount of activated carbon is fixed and is equal to (4 kg) for all the experiments that have been performed. Several quantities of Methanol were tested (650 g, 750g, 900g) to get the best system performance. The experimental test rig of present work was designed to produce 2 kg of ice by using Activated Carbon in a concentration of 0.28 kg Methanol/kg Activated Carbon. The shape of the flat plate type adsorber/collector was parallelogram with dimensions (110 cm× 67 cm×8 cm). The results show that the coefficient of performance of the unit decreases with increase the condenser and evaporator temperat.. The new in this paper that the maximum average of COP was 0.49 but the minimum was 0.4 that agree with literat. experiments in this field. | ||
