2. Стр. 4 Features

   York YLCS Water Cooled Screw Chillers are a compact design suitable for water or water-glycol cooling. Models are available in three versions: • Standard units (SA), • Units for applications requiring high condensing temperatures (HA) • Units for applications where remote condensers are necessary…

3. Стр. 5 Specification

   General YLCS models shall be completely assembled with all interconnecting refrigerant piping and internal wiring, ready for field installation. SA and HA units shall be pressure tested, evacuated, and fully factory charged with refrigerant and oil in each of the independent refrigerant circuits.…

4. Стр. 6 Refrigerant Circuits

   An independent refrigerant circuit shall be provided per compressor. Liquid line components shall include: manual shut-off valve with charging port, high absorption removable core filter-drier, solenoid valve, sight glass with moisture indicator, and thermostatic expansion valve. Suction lines…

5. Стр. 7 Accessories and Options

   ENTRY – Enter set point changes, cancel inputs, advance day, and change AM/PM. SET POINTS – Chilled liquid temperature, chilled liquid range, remote reset temperature range. CLOCK – Time, daily or holiday start/stop schedule, manual override for servicing. PRINT – Operating data or system fault…

6. Стр. 8 Power Factor Correction

   Factory mounted passive (static) correction capacitors to correct unit compressor power factors to 0.95 (depending on operating conditions).
