Features & Options
- Reverse cycle heat pumps allow for elimination of boiler systems by allowing the chiller to provide hot water for heating demand
- Heat pumps are available in 10 through 80-ton standalone units and can be combined in modular assemblies for up to 240 tons per array
- High efficiency scroll compressors and liquid injection scroll compressors available
- Air-To-Water Heat Pumps equipped with liquid injection compressors can generate up to 130°F (54°C) hot water at a 0°F (-17°C) ambient temperature.
- Two-pipe or Four-pipe configuration
- Four-pipe operation with brazed plate condenser sized for full heat recovery offers significantly more heating capacity than a desuperheater
- Heat recovery option can provide 140°F (60°C) hot water to reheat dehumidified buildings, pre-heat laundry or pool water
- Loop switching valves and modular hot water pipes factory installed.
- Standard uncoated or optional e-coated microchannel heat exchanger (MCHE) condenser coils for a better efficiency during defrost mode and a reduced refrigerant charge
- Highly efficient, dual circuit brazed plate heat exchangers offer maximum performance at both full and part-load conditions.
- Intuitive, factory installed microprocessor-based controller compatible with BACnet®, Modbus®, and LonTalk®
- Galvanized steel frame with painted epoxy finish on exterior panels minimize corrosion and promote long equipment life
- Ground or rooftop installation
- Compressors are factory installed on rubber isolation mounts for quiet operation
- Compressor acoustic hoods and/or sound isolating cabinets are available for sound sensitive applications
- ASHRAE 90.1compliant
- R-454B available
Modes of Operation
- Cooling Mode: The refrigerant-to-water heat exchanger is the energy source for the refrigeration circuit, absorbing heat from the chilled water. The refrigerant-to-air coil is the energy sink, rejecting heat to ambient air.
- Heating Mode: The refrigerant-to-air heat exchanger is the energy source in the circuit, absorbing heat from the outdoor air, while the refrigerant-to-water is the energy sink in the circuit, rejecting heat to the heating water circuit.
- Heat Recovery Mode: Heat pumps typically feature a single-load refrigerant-to-water heat exchanger capable of either cooling or heating, but not both simultaneously. With the addition of a heat recovery option, a second refrigerant-to-water heat exchanger is incorporated alongside the load heat exchanger. This secondary heat exchanger is designed to heat a separate fluid loop while the primary load refrigerant-to-water heat exchanger is in cooling operation. (4-pipe system + Heat Recovery Option)
