Features & Benefits
- Designed for high performance both at full load and at part load
- SCOP 47/55°C up to 5,4
- Inverter-driven twin-rotor screw compressors allow precise capacity matching of building load changes and significantly reduce unit power input, especially at part-load
- Flooded multi-pipe heat exchangers for increased heat exchange efficiency
- Electronic expansion device permits operation at a lower condensing pressure and improved utilisation of the evaporator heat exchange surface
- Optimised electrical performance
- Increased global performance as well as Carrier's acclaimed product quality and reliability
- Major components are selected and tested to minimise failures possibility, as well as many design choices have been taken in this perspective
- Inverter-driven screw compressors with oversized bearings and motor cooled by suction gas (liquid cooled motor on 1401 & 1601 models)
- The inverter is optimised for each compressor motor to ensure reliable operation and easy maintenance
- All compressor components are easily accessible on site minimising down-time
- Two independent refrigerant circuits (from 1,000 kW upwards); the second one automatically takes over, if the first one develops a fault, maintaining partial cooling under all circumstances
- Auto-adaptive control
- Exceptional endurance tests
- Specific polyol ester oil qualified by Carrier for using with HFO-1234ze or R-515B to guarantee and maintain reliable bearing lubrication
- Specific compressor gaskets compatible with HFO-1234ze or R-515B, tested and validated by Carrier
- New relief valves designed for operation with HFO-1234ze or R-515B
- New control algorithms
- Specific documentation that contains all the installation, operation, maintenance and safety Instructions
- Compact design
- Simplified electrical connections
- Simplified water connections
- Fast commissioning
- Low noise Greenspeed® variable-speed fans
- The inverter technology used for the compressor motors minimises noise levels at part load operation
- Silencers on the compressor discharge line
- Sound insulation on the components that are most subjected to radiated noise
- Option 257 further reduces the global unit sound level
- R-1234ze HFO long-term refrigerant solution with nearly zero global warming potential (GWP < 1) and zero ozone depletion potential (ODP = 0)
- R-515B future-proof A1 refrigerant
- Leak-tight refrigerant circuit
- A green building is a building that is environmentally sustainable and has been designed, constructed and is operated to minimise the total impact on the environment
- The air conditioning system can use between 30 and 40% of the annual building energy consumption
- A number of green building certification programmes exist in the market and offer third-party assessment of green building measures for a wide variety of building types
- Advanced control algorithms combine inverter frequency output with motor input logic to minimise mechanical part stress, resulting in best compression performance and high chiller reliability
- Equipped with bearings with oversized rollers, oil pressure lubricated for reliable and durable operation, even at maximum load
- Screw compressors use positive displacement principle to compress gases at higher pressure. As a result, in case of exceptional high temperature condenser side, the compressor does not switch off, but continues operation at reduced capacity (unloaded mode)
- The silencer in the discharge line considerably reduces discharge gas pulsations for much quieter operation
- Condenser includes an oil separator that minimises the amount of oil in circulation in the refrigerant circuit and redirects it to the compressor function
