摘　　要：以宜兴市某酒店工程为例,分析了酒店空调系统采用温湿度独立控制的适用性和技术优势,采用新风承担室内湿负荷、室内风机盘管承担显热负荷可以有效地降低系统能耗,解决了集中空调自身带来的室内空气污染问题,大大改善了室内空气品质。直接利用天然冷源产生的高温冷水可以显著降低冷源系统的能耗,同时采用设置两级表冷器的排风热回收新风机组,实现双级热回收,对新风进行预冷和再热,降低了新风处理能耗。夜间低负荷时段仅开启新风系统即可满足客房供冷需求,也可以控制空调系统的运行噪声,从而在保证室内热舒适环境的同时,进一步降低酒店空调系统的运行能耗。This paper takes a hotel project in Yixing as an example to analyse the applicability and technical advantages of the temperature and humidity independent control adopted in the hotel air conditioning system.Using outdoor air to bear the indoor latent heat load and the indoor fan coil to bear the sensible heat load can effectively reduce the system energy consumption,solve the problem of indoor air pollution caused by the central air conditioning itself,and greatly improve the indoor air quality.Directly using the high-temperature chilled water generated by natural cold sources can significantly reduce the energy consumption of the cold source system.At the same time,an outdoor air unit with a two-stage surface air cooler for exhaust air heat recovery is set up to achieve two-stage heat recovery,pre-cool and re-heat the outdoor air,which reduces the energy consumption of outdoor air treatment.During the low-load period at night,only turning on the outdoor air system can meet the cooling demand of guest rooms,and the operating noise of the air conditioning system can also be controlled.Thus,while ensuring the indoor thermal comfort environment,the operating energy consumption of the hotel air conditioning system is further reduced.
