1000kW compression type refrigeration water-cooled chiller design
ABSTRACT
The design is the 1000KW refrigeration compression type refrigeration water-cooled chiller; Location for China nanjing; Cooling water inlet temperature 32 ℃;increase 7 ℃ temperature of cooling water; the freeze water water inlet temperature 12 ℃; and the outlet temperature is 7 ℃ .
Design first scheme comparison, selecting the appropriate refrigerants and proper refrigeration circulation. And the refrigeration circulation thermodynamic calculation, calculate refrigeration in each state points and proper selection of compressor. From exchanger computation to obtain the Heat pipe decorated, and ensure the unit form. Calculate the hydraulic calculation obtain cooling water pump and freeze water pumps. Based on the data of whole design complete unit query and draw the corresponding unit figure.
Key Words: water chillers; thermodynamic calculation; heat-transfer calculation
