螺杆式水源热泵机组节能途径

Energy Saving Way of Screw-type Water Source Heat Pump Set

螺杆式水源热泵机组节能技术包括带经济器的准二级压缩循环、水平管降膜蒸发器、分段式冷凝器、节流装置选取。经济运行方式可采取开停机调节方式、变输气量调节方式。采用节能技术的新型螺杆式水源热泵机组的名义性能系数比传统螺杆式水源热泵机组提高了30%左右。

The energy saving technologies of screw-type water source heat pump set include the qua si-secondary compression cycle with economizer, hori zontal tube falling film evaporator, segmented condens er and selection of throttle. The economic operation mode can adopt the on/off regulation mode, the varia ble gas transmission amount mode. The nominal per formance coefficient of new screw-type water source heat pump set using the energy saving technology is a bout 30% higher than that of traditional screw-type wa ter source heat pump set.
