四管制风冷热泵在夏热冬暖地区恒温泳池的设计应用探讨

Design and Utilization of Heat Recovery Air-cooled Heat Pump for Thermostatic Swimming Pool in Hot Summer and Warm Winter Region

以地处夏热冬暖地区的福州某学校文体馆为例,从分析福州市的气候特征、游泳池空调负荷特性及池水恒温需求等方面着手,抓住温湿度控制要点,结合冷凝热回收技术,以四管制风冷热泵为基础构建了高效节能的冷热源系统,并与传统的冷水机组加燃气热水锅炉所构建的冷热源系统进行了分析对比。分析结果表明:在夏热冬暖地区的室内恒温泳池项目中,采用四管制风冷热泵构建的冷热源系统在全年工况的能耗均低于传统的冷水机组加燃气热水锅炉构建的冷热源系统,夏季工况下节能30%以上、减排33.2%以上,冬季工况下节能28.2%以上、减排19.4%以上,该冷热源系统具有良好的推广应用价值。

A gymnasium which is located in Fuzhou-the hot summer and warm winter area is analyzed.The climate characteristics of Fuzhou are expounded,as well as the air conditioning load characteristics and constant water temperature demand of swimming pool.Combined with the key points of temperature and humidity independent control and condensation heat recovery technology,an efficiency cooling and heating source system based on heat recovery air-cooled heat pump is established.This cooling and heating source system is also analyzed and compared with the traditional system based on water chiller and gas-fired water boiler,which shows that:the energy consumption of the cooling and heating source system based on heat recovery air-cooled heat pump is lower than that of the traditional system based on water chiller and gas-fired water boiler in the whole year,the energy saving is more than 30%in summer and more than 18.8%in winter,the carbon emission reduction is more than 33.2%in summer and more than 28.2%in winter.The cooling and heating source system based on heat recovery air-cooled heat pump has good application value in hot summer and warm winter areas.
