普传变频器在中央空调水泵中节能方案（Energy saving scheme of universal frequency converter in water pump of central air conditioner）

普传变频器在中央空调水泵中节能方案（Energy saving scheme of universal frequency converter in water pump of central air conditioner） Through frequency conversion, the refrigeration pump can automatically adjust the flow rate according to the outdoor temperature and indoor temperature requirements, improve efficiency, and achieve the goal of energy saving. (3) reduce the power supply and system impact when the air conditioner is on or off Reduce the impact of air conditioning on / off to the power grid. Because of the larger power of the circulating pump, the impact of the power on / off pump on the power grid is greater, affecting the operation of other equipment. After adopting frequency conversion control, the water pump realizes soft start and soft stop. The current is less than the rated current, and no longer impact on the power grid. The water drop effect of circulating water in stopping pump is reduced. Because of the soft stop of frequency conversion and the process of stopping pump can be controlled, the water drop effect at stop pump can be completely eliminated, and the impact of water sag on the pipe network of air conditioning system can be eliminated. (4) reduce the failure rate of equipment After the frequency conversion control, the circulating water pump works under the rated power for most time, which will reduce the failure rate of equipment and reduce the maintenance and maintenance of equipment. (5) improve the automation of the equipment The overload and over current protection of the circulating pump can be realized, and the temperature of the cooling water and the chilled water of the chiller is automatically controlled to ensure the safe and efficient operation of the unit. To sum up, the central air conditioning circulating water pump adopts frequency conversion control, which has obvious economic benefits, so it is necessary to transform the system. Three, central air conditioning frequency conversion scheme design: 3.1 frequency conversion scheme of cooling
