Study on Application of Condensate Water for The Packaged Air-conditioner

针对整体式空调器冷凝水应用进行了理论分析及实验验证,测试了在打水与不打水状态、采用不同翅片的冷凝器及不同打水间隙状态下的整机性能。试验表明:打水相比不打水,同比制冷量提升5.11%,EER提升11.19%,环保节能效果提升明显;冷凝器采用亲水翅片的性能会差于非亲水翅片的性能,制冷量和EER分别降低约2%和4%以内;打水圈与底盘间隙相对越小,能力能效取得更好的效果,但结构碰撞风险加大,8mm较为合适。

In this paper, the theoretical analysis and experimental verification are carried out for the application of condensate water in the packaged air-conditioner. The performance of the air-conditioner is testing between the different conditions： with hitting water and without hitting water, different fins, different gap of fan and chassis. The experimental results show that the capacity and Energy Efficiency Ratio improved 5.11% and 11.19% respectively by changing not hitting water to hitting water. The improvement of the environmental protection energy efficiency is obvious. The performance of the hydrophilic fins is worse than the non-hydrophilic fins, the capacity and EER difference of them are about 2 percent and 4 percent respectively. The smaller gap of fan and chassis is good for performance of the air-conditioner, but the risk of structural collisions increased, 8 mm is more appropriate.
