冰蓄冷与水源热泵系统设计实例

Demonstration design of ice-cold-energy accumulating system and water-head heat pump

为了克服冰蓄冷技术和水源热泵技术单独应用时的局限性,真正使二者有机结合起来起到“削峰填谷”的功效,通过对北京大红门服装城空调系统的设计,验证了冰蓄冷技术与水源热泵技术相结合的巨大优势。大红门服装城空调系统的最佳配置为2台1 260 kW三工况水源热泵机组、水源井5口和1套冰蓄冷空调系统,与常规空调系统相比,初期投资有所增加,约56万元,但年运行费用较低,与常规市政热力取暖系统进行比较,每个供暖季可节约212万元。

To overcome the limitation of ice-cold-energy accumulating system and water-head heat pump system in independent application and combine them effectively, a new type air-condition system of Beijing Dahongmen Clothing Shopping Center was designed to save energy by cutting power peak in day and filling valley in night. The fact shows the ice-cold-energy accumulating system integrating with the waterhead heat pump has more economic benefit and energy saving effect than the common air-condition system. The air-condition system of Dahongmen Clothing Shopping Center has two 1 260 kW three-work-condition water-head heat pumps, five wells and one ice-cold-energy accumulating system. The initial investment needs about ￥560 000, but it can save about ￥ 2 120 000 in one heat-supply season than that of the common air-condition system.
