摘要
结合酒店的空调能耗状况及冷热负荷特点,对酒店空调采用冷水机组冷凝热回收系统的节能性和必要性进行了探讨。以某五星级酒店空调工程为例,介绍了其空调热回收系统的优化设计。增大了热回收系统的供回水温差,同时采取热水罐串级连接,对水温进行分层,有效地实现了热水的梯级利用及顺序利用。经分析,该优化系统更加充分地利用了冷水机组的冷凝热,更加节能,而且供水温度比较稳定。
Based on the energy consumption of the air conditioning system and the characteristics of the cooling and heating load in hotels,studies the energy efficiency and necessity of adopting condensing heat recovery from water chillers.Taking an air conditioning project for a five-star hotel as an example,presents the optimization design of the air conditioning heat recovery system,in which an increased temperature difference between supply and return water and the hot water tanks in series are adopted,effectively realizing cascade and sequential utilization of hot water based on the water temperature stratification.The analysis results show that the system makes better use of the condensing heat of water chillers and is more energy efficient,and hot water supply temperature is relatively stable.
