The 61XW water-source heat pump chiller known for it’s energy saving, environmental friendly and high reliability are becoming more and popular in air conditioning system handling choice. This application has two operating models, cooling and heating maximum temperature up to 63°C and ACOP up to 6.38kW/kW at China GB standard. This chiller can take advantage of a variety of low heat source, such as water/ground source, buried loop source and surface water source reflect a multi-purpose function.
61XW is ideally suitable for LEED®-certified buildings and green projects, high-end hotels, offices, schools, hospitals and building types, it saves about 30% energy consumption compared with the conventional air-source heat pump system and about 70% of energy consumption compared with electric heating model.
Performance Features
- Environmental stewardship and chlorine-free refrigerant HFC-134a
- New twin-rotor screw compressor equipped with a high-efficiency motor
- Variable capacity valve that permits exact matching of the cooling capacity to the load
- Flooded multi-pipe evaporator and condenser for increased heat exchange efficiency
- Electronic expansion device permitting operation at a lower condensing pressure and improved utilization of the evaporator heat exchange surface (superheat control)
- Entering-fluid temperature continuously monitored to detect flow or load changes
- Compatible with Carrier Comfort Network® (CCN) communication link
Reliability Features
- Industrial-type screw compressors with oversized bearings and motor cooled by suction gas.
- Reduced number of moving parts, with compressor rotors directly driven by the motor, to lower the failure rate
- Electronic paddle-free flow switch. Auto-setting according to cooler size and fluid type
- Low voltage control circuits
- Short cycle protection
Maintenance Features
- Hermetic twin screw compressors
- Mechanically cleanable condenser and evaporator
- Alarm contacts
- Filter drier
- Accessible service information including suction and discharge pressure and temperature using Navigator™ display module (factory-installed option or field-installed accessory)
- Discharge and liquid line shutoff valves (factory-installed option)
- ON/OFF control switch
Installation Features
- With a relatively small width, only require minimum floor space in the plant room
- Victaulic connections on the evaporator and condenser, easy and fast installation
- Possibility to reverse the heat exchanger water inlet and outlet at the factory
- Simplified electrical connections, main disconnect switch with high trip capacity and transformer supply to the integrated control circuit (400/24 V)
- Fast commissioning, systematic factory operation test before shipment
