CO2 HEAT PUMPS

The eCOHeat line of heat pumps derives from our wide-reaching technology portfolio in heat transfer, refrigeration systems, materials engineering and control integration.

We offer fully de-carbonized, clean and green heating-cooling solutions which are predictably low on running-cost, driving the change towards energy sustainability.

High impact decarbonization is possible in the following use cases:

 

  • Industrial Process Heat
  • Pharmaceuticals
  • Food and Beverages
  • Food and Beverages
  • Automotive Ancillaries
  • Warehousing and Storage
  • Paints, Chemicals, Textiles

EFFICIENT ENERGY RECOVERY

Environmentally Friendly Refrigerant

• Global Warming Potential = 1
• Non-flammable
• Non-toxic
• Non-corrosive

Optimized Energy Consumption

• 25%-90% running cost savings compared to conventional heat sources
• Measurable, repeatable savings
• 100% decarbonization with green electricity

Heat Recovery

• Full reject heat is recovered
•Heating ranges from 35 °C to 90°C
• Cooling/refrigeration possible on cold side
• Instantaneous heating/cooling duty

Freedom from Combustion

• No fuel storage/handling
• No ash/waste management
• No stack emissions
• Non-corrosive

Easy to use

• Small footprint
• Plug-and-play systems
• Capacity scales in “racks”- 50 kW to 2 MW heating and from 10 TR to 600 TR cooling

EFFICIENT ENERGY RECOVERY

  • Process, CIP, washing, sterilization
  • Chilled water as required

Pharmaceuticals, API, Bulk-Drugs

  • Sanitary hot water for process
  • Process water for heating/cooling

Industrial Process Heat

  • Process tanks, jacketed heaters
  • Pre-heated feed water for steam

Hospitals and Medical Complexes

  • Sanitary water for hygiene requirements
  • Air-conditioning for OT/ICU/Rooms

Hotels and Convention Centers

  • Hotels and Convention Centers
  • Air-conditioning throughout

Warehousing and Packaging

  • Hot water for cleaning, washing
  • Cold air to maintain temperature

EFFICIENT ENERGY RECOVERY

eCO2Heat systems recover heat in the form of hot water from the high-pressure end of CO2 refrigerant cycle while the low-pressure energy recovery generates chilled water. The refrigerant characteristic allows for running at various temperature thresholds for closed circuit or once-through operation modes with flexible delta T. Installations are designed to complement the existing capital equipment to ensure fast changeover and redundancy.

The design and development of the eCO2Heat series is supported by research groups from Indian Institute of Technology, Madras (IITM) and Norwegian University of Science and Technology (NTNU), all part of the INDEE+ consortium.

PRODUCT AND SYSTEM FEATURES

The eCO2Heat machine is fully factory assembled and tested
  • High-pressure compressors with optional Variable speed drive (VSD) for stepless capacity control
  • Modulating ejector technology for optimized COP in varying ambient/duty conditions
  • Oil separator, oil management system, and related controls
  • Optimally sized receiver to handle CO2 charge and withstand standstill pressures
  • Internal heat exchangers to optimize the heat-pump performance
  • PLC integration to cloud and remote diagnostics
The system for your application is delivered as a turnkey project which integrates the machine with loads:
  • HVAC/R packages consisting of AHU, Air-path ducting and chilled-water control
  • Hot water circuit with stratified storage tank for high temperature heat storage reservoirs
  • Waste-heat and free cooling recovery modules for intermediate temperature/comfort operations
