对基于蒸发式冷凝器的空调系统进行了性能测试,结果表明即使在相对湿度较大的运行环境下,空调系统性能系数(COP)仍可达到3.5左右,证明即使在夏热冬暖地区,基于蒸发式冷凝器的空调系统仍具有较好的系统效率;空气湿球温度对蒸发式冷凝器的排热性能影响明显,在测试范围内,当其它控制参数不变时,湿球温度每上升1℃,排热量下降5％左右.本研究还对蒸发式冷凝器及空调系统进行了变工况条件下的性能测试,结果表明随着冷负荷的降低,系统COP和冷凝器能效比均有所下降,但采用变风量的运行控制策略可使系统性能系数提高5％以上.

A performance test of air condition system based on evaporative condenser is car-ried out. The results of test show that the system's coefficient of performance (COP) is up to around 3. 5 even if it running in an ambient of larger relative humidity. The heat emission capacity of evaporative condenser is impacted obviously by the wet bulb temperature of air.When other parameters constant,the heat emission decreases around 5% while the wet bulb temperature rise by one degree Celsius in the testing scope. The testing results for a variable working condition displays that the system's COP and the energy efficiency ratio (Ra) of e-vaporative condenser are decreased along with the reducing cold load. The results also dis-plays that the system's COP can increase upwards to over 5% while a variable frequency drive for the induced fan is used.
