Energy source station efficiently especially big cooling capacity is connected water-cooled cold water unit.
Background technique
Existing water-cooled cold water unit, compressor, evaporator, condenser and expansion valve compactly fit together.It is more
When platform water cooler is used in parallel, the higher chilled water of the temperature that end is flowed back to is responsible for each branch pipe separated along chilled water return water
The water cooler in parallel into each is incorporated to chilled water vibration means for main pipe for supplying water after cooling down, then by each chilled water water supply branch pipe, then is supplied to
End.Because of the reasonable installation space that the connection of a plurality of branch pipe and water cooler itself need, the water cooler of this form
Occupied space is larger.
Water cooler operational efficiency in higher load rate is high, and operational efficiency is low when middle low-load.When end load is smaller,
I.e. refrigeration requirement is small, but because cooling supply region is big, when chilled-water flow demand is larger, using existing water cooler, if operation platform
Number is few, and separate unit water cooler may operate in high efficient district, and general power is lower, but because the caliber of evaporator limits, the freezing of conveying
Water flow is less than normal, and end cannot get sufficient chilled-water flow, partial region poor refrigerating efficiency；If the number of units of operation is more, conveying
Chilled water can satisfy end demand, but separate unit water cooler operates in underload, inefficient area, and general power is higher.Because cold
Water dispenser group is matched by highest cooling load, so the most of the time operates in above-mentioned running on the lower load, the energy of cold water main unit
Consumption is high.
For guarantee water cooler safe operation, no matter water cooler high load or middle low-load operation, chilled water pump is all
It has to last for providing substantially stationary lift consumption for it, typically no less than 80kPa causes chilled water pump energy consumption higher.
Existing water cooler, the chilled water supply backwater temperature difference of design are usually 5~8 DEG C, and when operation, the practical temperature difference is higher than
Or it is lower than design value, the efficiency of water cooler can all reduce.Also, existing water cooler, can not be cold to adjust on a large scale
The mode for freezing water supply water temperature (6~12 DEG C), realizes the chilled water return water temperature of setting.Therefore, frequent to the end demand temperature difference
Variation, and relatively fixed return water temperature is just able to maintain the project of comfort level, existing water cooler cannot continue, efficiently, effectively
Ground provides cooling capacity.
