  1. Trane Variable Water Flow System Outdoor Air-cooled Water Chiller Installation, Operation & Maintenance

  2. Trane Variable Water Flow System • Introduction • What is VRF system? • System Profile • System & Components • Chiller Unit • Nameplate

  3. Trane Variable Water Flow System What Is It? Digital Chiller Trane Variable Water Flow System Cassette High Wall Concealed Concealed RS485 Central Controller Thermostat Thermostat Remote Controller Remote Controller Inflow Water loop Outflow Water loop Communication line 3 • A newlydesigned,digitally controlled air-cooled variablewater chiller system • Variable Refrigerant Flow in Refrigeration Loop & Variable Water Flow in water loop • Water used as heat transfer media, no refrigerant in occupied space

  4. Outdoor Unit • Digital Scroll Compressor • Built-in two-speed water pump • Fan design delivers reduced noise levels Cooling capacity range 6RT 8RT 10RT 12RT 14RT • CGD*100/ 120/ 150/ 175/ 200 • Cooling: 24.5kW - 48.5kW • Heating: 24.5kW - 48.5kW • Power source: 220V/60Hz/3Ph • 380V/50Hz/3Ph

  5. Outdoor Unit 10RT 12RT \ 14RT 6RT \ 8RT Digital Fixed Digital Fixed Digital Fixed Fixed Cabinet Size (mm) (HxWxD): 1,900 x 1,290 x 600 Cabinet Size (mm) (HxWxD): 1,900 x 1,990 x 600 Cabinet Size (mm) (HxWxD): 1,900 x 1,990 x 600

  6. Digital Scroll Compressor • Pulse Width Modulation (PWM signal) • 10-100%continuous capacity control • Superior performance • Simplified control parts

  7. System Controllers Type Central Controller (Standard) Controllers Unit Controllers Type of ID Wired Remote Concealed NotAvailable Cassette • Central controller is a “must have” • Wired thermostat is Trane Patented design • Color back light • Last setting for resuming power Hi-Wall Notavailable

  8. Controllers Wired Controller Remote Controller Central Controller • Remote ON/OFF fan coil • Function setting, temperature regulation, air velocity setting • Sleep mode setting, timer setting function • Remote control distance ≥5M • Patented design • LCD display • Cooling/heating/ ventilation control • Sleeping mode • Last setting for resuming power • Multi-zone control • Individual zone control • Troubleshooting • Timer setting • Mode setting

  9. How to Select “EarthWise” OD Parameter Setting: Set leaving water temp to 5°C via central controller • In-Door Unit Selection: • Concealed unit: select “Earthwise” application • High wall & Cassette: Not available • Digit 17: Application • N = Normal application • E = Earthwise Choose “Earthwise” option in TDS tools to run product configuration report

  11. PVC Pipe Installation Benefits • PVC pipe and fitting price is 4 times cheaper than steel pipe’s. • PVC Pipe weight is 6 times less than steel pipe’s. • Use smaller pipe size because friction loss of PVC pipe is much less than steel pipe’s. • Easy transportation, Easier and quicker installation, longevity
