寒冷地区(B区)太阳能新风除湿系统及其可行性

摘要

结合寒冷地区(B区)气候特征和夏季新风负荷特点给出一种太阳能驱动的转轮除湿与空气源热泵结合的新风处理系统,并以西安地区为例进行系统可行性分析.气象统计分析数据显示,该区夏季太阳能资源丰富、稳定、利用价值高(约44％～56％);通过对典型城市新风负荷的解耦计算,该区新风负荷中潜热负荷所占比例较大,占总负荷比例约为60％～85％,新风处理过程除湿能耗大于降温能耗;采用太阳能新风除湿系统降低了空调系统中新风处理机组能耗.%A fresh air handling systems combined rotary dehumidifier powered by solar energy and air-source heat pump is given based on the characteristics of climate and summer fresh air load in the cold region.,and the system feasibility is analyzed in Xi'an.Meteorological statistical analysis data shows that the solar energy in summer of the cold region is rich,stability,higher utilization efficiency (44％～56％);The results show that the latent heat load has a larger proportion in the fresh air load by decoupling the load of fresh air to the main city of this region,and it was accounted for about 60％ to 85％.The energy consumption of dehumidification is greater than the air cooling in fresh air treatment;The energy consumption of fresh air handling unit can be reduced by using the fresh air dehumidification system in air conditioning system.
