【摘要】 针对分布式变频泵供热系统,提出按照热量控制的方法。该控制方法的特点是:直接采用热量控制,改变了传统用供回水温度来间接控制的方法。针对分布式变频泵供热系统,热源处按照热量总量控制,主循环泵按照压差控制,分布泵按照热量-温差控制的方法。通过该方法可以保证供热质量,并最大限度地保证了供热系统的稳定性,延长了设备的使用寿命。更多还原

【Abstract】 The thermal control is proposed for the distributed variable frequency pump heat system.The feature of the method is using the heat to control directly,not using the supply and return water temperature to indirectly control.For the distributed variable frequency pump heat system,the heat source is controlled with the thermal total amount;the main circulating pump is controlled with differential pressure;the distribution pump is controlled with thermal and constant temperature difference.The control method could not only guarantee heat quality and the maximum stability of the heating system,but also extend the life of the equipment.更多还原
