(1) Install the energy -saving water pump on the end of the condenser and the evaporator, and use the inhaled layout type to install it, especially for the cooling circulating water system of the cooling tower with a fan spraying tower. Pressure is more conducive to exerting the rainbow absorption function of the energy -saving pump. It can reduce the loss of the kinetic energy of the pump pump, make the system hydraulic balance well, and significantly reduce the operation of the energy -saving pump axis and reduce the energy consumption in operation. However, the energy pump is suitable for the water intake end of the boiler at the time of heating with the boiler. The use of this method of pumping can make the energy -saving pump better play.

(2) Energy -saving water pump is limited to the application of cooling, freezing, and heating circulating water industry circulating water systems of the central air -conditioned cold water units. The water head static pressure at the energy -saving pump inlet at the time of cooling cannot be lower than 0.04MPa. When the supporting heating water temperature is within the range of 60 degrees to 90 degrees, the water -saving pump inlet water static pressure cannot be lower than 0.06MPa.

(3) The energy -saving pump has a good plain curve. When the traffic changes are small when the flow changes, it is recommended that during the design or energy saving transformation of the freezer system The bypass pipe is canceled.
