关于综合医院空调系统的优化研究

Optimization on General Hospital Air Conditioning System in Cold Region

我国建筑能耗约占社会商品能源总消费量的25%,其中建筑空调系统能耗约占建筑能耗的50%,空调在满足了人们舒适度的同时,空调节能备受关注。在影响医院能耗的众多方面中,新风量的能耗引起了更大关注。由于医院空调系统的特殊性,医院对空气品质的特殊要求,使得医院空调系统中新风量比例偏大,尤其是有洁净要求的手术室等特殊病房。以洁净手术室为例,研究了使用全热交换器的技术可行性和经济合理性,以类似工程热回收效率60%为参数,计算得出夏季(6—9月)采用排风热回收装置单位新风量可回收的能量约为75.65 GJ,每年可节省2.4万元。

China＇s building energy consumption accounts for the total energy consumption of social goods 25%, of which energy consumption of building air conditioning system accounts for about 50% of building energy consumption, air conditioning is satisfied for the comfort of people at the same time, the air conditioning energy conservation is a major concern. In many respects of influencing hospital energy consumption, energy consumption of fresh air volume caused greater attention. Due to the particularity of hospital air conditioning system, hospital special requirements for air quality, the proportion of new hospital air conditioning system of large quantity, especially the requirements of clean operation room and special wards. Taking the operating room as example, the technical feasibility and economic reasonableness of total heat exchanger are expounded. The recyclable energy of unit mass of fresh air by utilizing the exhaust heat recovery device in summer（June-September） is calculated about 75.65 GJ, with annual cost-saving of24,000 Yuan, taking similar project＇s heat recovery efficiency of 60% for the parameters.
