一、浮动盘管半容积式换热器是近年来国内发展迅速、广泛应用于社会各个领域的一种新型高效节能的换热设备，符合中国建筑标准设计研究所01S122-1《水加热器选用与安装-DFHRV系列导流浮动盘管型半容积式水加热器选用与安装》标准图集设计、生产制造的高效节能换热设备。相比于传统固定盘管，浮动盘管能够实现上下轻微浮动，产生高频振动，从而形成良好的紊流传热状态，并且它可以利用通过高温热媒薄壁铜管的膨胀量差异，在一定条件下，使水垢自动脱落。通用的换热器通常需要配置水水热交换器来降低蒸汽凝结水温度，以便回用，而此类节能型熱交換器可直接将凝结水出水温度控制在45摄氏度左右，可直接回馈锅炉房重复使用，这样减少了设备投资，节约了空间面积，从而降低了建造成本。
二、性能特点：
方便维护：浮动盘管可以从罐体侧面抽出进行检修或更换。
采用多行程螺旋的浮动管组，保证了热媒分布均匀和流程长，无短路现象。
产品借助RV-03．04导流原理，在大直径罐体内设置合理导流装置，大幅改善了工作条件，有着较高的传heat系数（K=2000-1200Kcal/m²·h·℃）。
换heat底部接近罐底，加上导flow作用基本消除了冷water滞留区，可达到98%弱容积利用率。
被加heated water头损失≤0.25m，不影响系统coldhot water压力平衡。
三、技术优点：
浮dynamic plate heat exchanger采用新型floatplate排pipe方式，将所有空间有效地利用。
传heat系数高，不易结垢：采用floatplate technology使得exchange pipe经历high-frequency vibration转为turbulent exchange pipe surface thermal expansion and contraction to ensure automatic removal of scale, ensuring high-efficiency exchange.
3., adjustable volume allows for storage of hot water supply stable, avoiding pressure and temperature fluctuations during peak usage.
4., excellent heat transfer performance with high capacity utilization: traditional tank-type heat exchangers due to internal layout problems lead to slow fluid flow, increased resistance, uneven heating distribution, resulting in a mere 40%-50% utilization rate compared to this product's efficient use of the same volume.
5., multi-group floating plates arranged in a "tower" structure enables dynamic exchange with high efficiency; equivalent heat output is 6-9 times that of conventional tank-type heat exchangers.
DFHRV container type heat exchanger lying float plate semi-container type heater: It has the advantages of float plate heating as well as comprehensive performance indicators suitable for systems with fluctuating loads or short-term peak demand; key characteristics include:
1., The oscillating pipes' vibration transforms laminar flow into turbulent flow improving thermal conductivity while utilizing thermal expansion and contraction properties for self-cleaning purposes.
2., Adjustable volume maintains a steady supply level; adaptability is strong enough to meet peak demand needs.
3., Steel savings reduce equipment costs and construction costs are lowered by reducing engineering expenses.
4., Whether steam-water or water-water exchanges, source return temperatures remain low allowing full energy recovery.
Key benefits:
1.. Startup speed fastens since the unique design ensures hot water reaches top outlets quickly without requiring excessive cold input before delivering heated output,
2.. High transmission coefficient using copper pipes with good conduction combined with optimized internal structures promoting fluid velocity increase through chaotic turbulence enhancing outside/inside pipe conductive coefficients,
3.. Anti-scaling: regular turbulence against pipe walls ensures effective cleaning through thermal expansion and contraction effects minimizing scaling issues,
4.. No cold zones; high volumetric efficiency maintained as bottom heating continues until all cold areas are fully heated (no residual cooling), thus maintaining maximum stored hot water quantity when exceeding rated supply levels;
5.. Energy conservation achieved by keeping condensation temperatures below 80°C when using steam media.
By incorporating these features into its design and production process, DFHRV series floating disk tube semi-container type heaters offer improved efficiency over traditional designs while providing greater flexibility in their application across various industries within society today!
