摘要
叙述了普通螺杆式风冷热泵冷热水机组,为满足低环境温度制冷正常运转,通过细化冷凝风机的控制范围,使机组冷凝压力稳定在标准工况内,而对冷凝风机控制电路所做的升级改造。
This paper describes the ordinary screw-type air Cooling heat pump chiller.To ensure normal operation of the unit under the condition of low temperature,we need to upgrade the condenser fan by refining the condenser fan control in order to make sure condensing pressure in the standard condition.
