Evaporatively-cooled Condenser with Rotating Disks
摘要
The utilization of evaporative cooling to improve the heat transfer and lower the condensing temperature for a residential heat pump is investigated experimentally. A novel bench-scale evaporative condenser is tested for its performance as a function of several parameters, and the design is optimized using the resulting data. Parallel air flow condenser configuration to two thin disks is examined. Moreover several turbulence enhancing devices are tested to improve the heat removal rate. The test data of the bench-scale condenser is then projected by computer simulation to design a full-scale condenser for a 9 kW residential air-conditioner application. A full-size prototype evaporative condenser with rotating disks was built and tested under the ASHRAE test conditions. The evaporative condenser showed a higher capacity by 1.8 to 8.1%, a higher COP by 13.5 to 21.6%, and a higher SEER by 14.5% than those of the baseline conventional air-coil unit.
