Modular Air-to-Water Heat Pumps

Jetson Air-to-Water Heat Pump units are air-source refrigeration units with the ability to produce chilled or heated fluid with one refrigerant-to-water heat exchanger. A refrigerant reversing valve is used to switch between cooling and heating modes.

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
  • UL 60335 compliant for R-454B refrigerant

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)
