埋管式水冷多联机系统运行时,如能根据负荷变化及时调整埋管换热器开启数量,进而改变水系统流量,则不仅可降低水泵的电耗,还可以实现埋管换热器间歇运行,从而提高系统的运行效率。本文研究了数码涡旋水冷多联式空调系统在冬季供暖运行工况下,改变闭式水环路的水流量对水冷多联机机组供回水温度的影响,分析了变水流量对系统运行特性和机组性能的影响。 Buried tubular water-cooled multi-line system running, such as load changes in a timely manner to adjust the number of open tube heat exchanger to open, and then change the water system flow, not only can reduce the pump power consumption, can also be realized intermittently ground heat exchanger , Thus improving the system’s operating efficiency. In this paper, the influence of water flow of closed-loop water loop on the temperature of water supply and return of water-cooled multi-unit is studied under the condition of heating operation in winter, and the influence of variable water flow on system operating characteristics And the impact of unit performance.
