Industrial chiller and screw type chiller is a provide chilled water refrigeration device, can according to the needs of the user to tailor-made screw chiller, screw chiller refrigeration condition: water freezing temperature of 12 degrees, water 7 DEG C, cooling water inlet 30 DEG C, cooling water 35 DEG C; the work scope of the unit: frozen water temperature 5-20deg C; the programmable controller of the PLC program control, touch screen man-machine interface operation, the pressure of the screw type chiller is how the formation of?
Screw type cold water purifier cooled and air-cooled two, the difference between the two is refrigerant condensing mode (ie, cooling way), compressor in exhaust pressure (high) and heat dissipation have direct relationship, and inspiratory pressure (low pressure) is with the temperature of the frozen water have direct relationship.
Screw chillers in summer outdoor temperature is 32 degrees and good ventilation conditions, water cooled high pressure in the 14 ~ 18Kg/ cm of 2, belongs to the normal range, if the ultra 22kg / cm 2, the unit will protect arrest; high pressure air-cooled in 17 to 22kg / cm 2 belongs to the normal range, if the ultra 28Kg/ cm, the unit will protect jump stop. Screw chiller compressor low pressure with chilled water temperature and flow, the evaporator outlet for 7 DEG C, low pressure for 2 cm 4Kg/ and water for 15 DEG C, low voltage 4.8Kg/ cm 2 or so, the effluent is 20 DEG C, low voltage 5.3Kg/ cm 2 or so. Screw chillers stop of the compressor when the pressure is also with the temperature is proportional to. Summer is generally 10 to 11Kg/ cm 2, winter for 8 ~ 9Kg/ cm 2.
