压力独立控制阀在瑞典屋恏的奇迹工作

2020年4月22日星期三

冬天在瑞典的哥德堡很长，黑暗和冻结。因此，淋浴的一个美好，温暖的客厅和大量的热水是寒冷的季节所必需的。不幸的是，生活在哥德堡驻房区公寓的人既没有。供应加热和热水不稳定，并在设施经理办公室堆积。此外，区供暖返回温度太高，导致当地区域供热公司的大量刑罚和高能源票据。

第一步：安装能源管理系统

呼吁DUNDERON的能量控制专家来帮助解决问题。密切检查现有的加热和热水装置后，他们在分散的变电站上推出了DUNDERON能源管理系统，用于室内加热和国内热水中央变电站。
之后，在公寓里开始改善。房间温度舒适，现在热水供应更稳定。然而，区供暖效用远非满意。主要区域供热侧的流动现在甚至更高，并且它们没有改善返回温度。能源法案上升，住房协会和居民不得不支付良好的措施以保持温暖。显然，次要方面有些错误，Dunderon要求Danfoss帮助提供一个解决问题的解决方案。

第二步：PICV和新型热交换器解决了问题

在密切合作中，合作伙伴决定用来自Danfoss的新型微通道换热器更换变电站的现有热交换器。此外，现有的双向控制阀被用于区能源系统的AVQM压力独立控制阀所取代。
新系统设计允许对辅助循环中的基本操作参数进行一些根本的更改。泵流量水平可降低40％至20％，并且供应温度减少10度至仅60℃。
结果实现了每个人的期望。居民现在始终享有舒适的室内环境和热水，而住房协会可以将能源成本降低25％。他们甚至收到了地区能源公司的奖金，以回报低流量和低回温。

变电站升级与压力独立控制阀和新型热交换器的好处

AVQMS如何解决问题

压力独立控制阀：
•防止振荡超过控制阀
•提高温度控制精度
•能够降低供应温度 - 没有溢出
•降低返回地区供热系统

Differential pressure controllers keep a constant and lower differential pressure across a motorized control valve or a total system/substation. This eliminates pressure variations and improves temperature control quality.
