The message is displayed when the determined flow rate across the terminal unit is higher than the required flow. Hydraulically unbalanced circuits are diagnosed by displaying the message:
当所确定的通过末端装置上流量高于所需流量时,就会显示该消息。被诊断出水力不平衡的回路就会显示下述信息:


* '''Unbalanced circuit of "XY" terminal unit (XY% of required flow) - check capabilities of control components in circuit'''
* '''"XY" 末端装置的回路不平衡 (所需流量的 XY%) - 检查回路中控制部件的能力'''


Unbalanced circuits may result from:
回路不平衡的原因可能如下:
* lack of valves that limit maximum flow or control the flow across the units (e.g. thermostatic valves),
* 缺少限制通过末端装置最大流量或控制流量的阀门 (如:温控阀)
* insufficient control/balancing capabilities of the fixtures used (e.g. excessive kv at minimum setting of the valve),
* insufficient control/balancing capabilities of the fixtures used (e.g. excessive kv at minimum setting of the valve),
* incorrect distribution in Tichelmann system (lengths of circuits, between the source and every subsequent terminal unit, should be similar),
* incorrect distribution in Tichelmann system (lengths of circuits, between the source and every subsequent terminal unit, should be similar),
* incorrect specification of pipe types and/or pipe diameters for connections of ''<IS_TS id=strSPGCh/>'' or pipe-runs feeding the terminal units (diameters of the feed pipes and of the circuit proper should match).<br/>Inconsistency in diamters may result in incorrect/excessive use of connecting fittings which increases flow resistance and differences in pressure drops,
* incorrect specification of pipe types and/or pipe diameters for connections of ''<IS_TS id=strSPGCh/>'' or pipe-runs feeding the terminal units (diameters of the feed pipes and of the circuit proper should match).<br/>Inconsistency in diamters may result in incorrect/excessive use of connecting fittings which increases flow resistance and differences in pressure drops,

问题描述

当所确定的通过末端装置上流量高于所需流量时,就会显示该消息。被诊断出水力不平衡的回路就会显示下述信息:

  • "XY" 末端装置的回路不平衡 (所需流量的 XY%) - 检查回路中控制部件的能力

回路不平衡的原因可能如下:

  • 缺少限制通过末端装置最大流量或控制流量的阀门 (如:温控阀),
  • insufficient control/balancing capabilities of the fixtures used (e.g. excessive kv at minimum setting of the valve),
  • incorrect distribution in Tichelmann system (lengths of circuits, between the source and every subsequent terminal unit, should be similar),
  • incorrect specification of pipe types and/or pipe diameters for connections of 供热/供冷区 or pipe-runs feeding the terminal units (diameters of the feed pipes and of the circuit proper should match).
    Inconsistency in diamters may result in incorrect/excessive use of connecting fittings which increases flow resistance and differences in pressure drops,
  • differences in sizes of terminal units or groups of terminal units in a Tichelmann system.

Solution

  • Proper specification of pipe types and/or diameters for connections to 供热/供冷区 or pipe-runs feeding the terminal units.

  • Use flow control components.
  • Eliminate differences in sizes of terminal units by connecting them in series.
