Using Condensate Water to Reduce Heat for Finned-Tube Condenser of Air Conditioning System
MetadataShow full item record
Now a day the mostly air condition are use vapor compression refrigeration system in which R-22 refrigerant is used as a working substance. From the results of study, it found that the quantity of water vapor or moisture in the air is condensed with in the fan coil unit while through out the evaporator. The fluid after condense is called condensed water. By this process, the quantity of condensed water is increases when the air condition is used in the long time. To increase the utility, the condensed water is recovered for the heart reduction in the finned-tube condenser. The experiment is consist of two conditions by using the air and condensed water to heart reduction. But in case of condensed water, the pressure operation is controlled at 280 and 260 Psig respectively. The results of experiment shown the refrigeration effect, coefficient of performance (C.O.P) and energy efficiency ratio (EER) is 39,675 Btu/hr, 3.01 and 10.3 Btu/hr.Watt respectively with the air is used. At the pressure operation 280 Psig, refrigeration effect, (C.O.P) and (EER) is 44,212 Btu/hr, 3.38 and 11.5 Btu/hr.Watt respectively and 49,856 Btu/hr, 3.99 and 13.6 Btu/hr.Watt at pressure operation 260 Psig. Furthermore, the capacity of condenser is increases to 11.43% and 25.6% and also the refrigerant efficient is increases to 12.43% and 32.43% at the pressure operation 280 and 260 Psig. Thus, the parameter of the energy efficiency ratio depends on the capacity of condenser, working substance temperature (pressure operation) and air surrounding temperature.
