基于寒冷地区被动房建筑新风机组适用性研究

Feasibility of Fresh Air Handling Unit Based on Passive House in Cold Region

利用EnergyPlus软件对河北省秦皇岛市某典型被动式低能耗住宅建筑进行全年逐时负荷模拟。根据模拟结果,设计了集制冷、制热和排风热回收功能的新风机组,对其在全年工况下运行的特性进行了实验研究,并将模拟负荷与实验结果对比分析,证明了新风机组设计的合理性,同时也验证了机组能完全满足寒冷地区被动房建筑的适用性和舒适性要求。该新风机组在寒冷地区的被动房建筑中具有可推广性,研究中的实验数据为今后相关产品的开发和实际推广提供一定的借鉴与参考。

Annual hourly energy consumption of a passive low - energy residential building project named ＂Another Side of the River＂ in Qinhuangdao, Hebei province, are simulated by EnergyPlus software. According to the simulation results＇, the fresh air handling unit combined refrigeration, heating and ventilation heat recovery functions are designed. The experiments＇ of operational characteristics of whole- year operation condition can be conducted, and the experimental data are analyzed. Combined with the simulation results＇, the rationality of the fresh air handling unit is provided, and at the same time the unit can completely meet the applicability and comfort requirements＇ of Passivhaus in cold region. The fresh air handling unit is probable in Passivhaus at cold region, and the experimental data can serve as reference for the exploitation and practical generalization of the relative product in the future.
