Knowledge stickers: the difference between frozen water pump and cooling water pump

Many people are not familiar with chilled water pumps and cooling water pumps, often mistaken for little difference between the two. Although the chilled water pump and the cooling water pump belong to the water circulation system, the difference between the chilled water pump and the cooling water pump is quite different. The differences are as follows: The development of the chilled water pump with high chroma value. As we all know, the selection of the water pump requires two parameters: flow and lift, Therefore, the difference between frozen water pump and cooling water pump is also based on this. Chilled water pump: As long as the water system will use a chilled water pump, such as water-cooled screw, air-cooled screw, air-cooled module; chilled water pump connected to the chilled water backwater pipeline. Chilled water pump: L (m3 / h) = Q (kW) / (4.5 ~ 5) ℃ x1.163 Chilled water pump head: cooling system along the pipeline resistance and local resistance, unit evaporator pressure drop, end equipment pressure drop . Cooling water pump: is used in water-cooled unit system. Such as water-cooled screw. Cooling water pump installed between the cooling tower and water-cooled unit. Cooling water pump: The flow rate depends on the water flow of the unit condenser, which is generally 1.2 times of the unit condenser water flow rate. Cooling pump head: condenser resistance, pipeline resistance along the way and local resistance, cooling tower height difference.
