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.
The performance test of the air conditioning system based on evaporative condenser shows that the performance coefficient (COP) of air conditioning system can reach about 3.5 even in the operating environment with relatively high relative humidity, which proves that even in the hot summer and warm winter area , The air-conditioning system based on evaporative condenser still has better system efficiency; wet bulb temperature has obvious influence on the heat removal performance of the evaporative condenser. When the other control parameters are unchanged, Increased by 1 ℃, and discharged heat decreased by 5% .This study also tested the performance of evaporative condenser and air-conditioning system under varying working conditions. The results show that with the decrease of cooling load, both the COP of the system and the energy efficiency of the condenser But the operation control strategy with variable air volume can improve the system performance coefficient by more than 5%.
