All in One CO2 Heat Pump KRF-120IIC

The KRF-120II/C represents a perfect balance of efficiency and capacity within mid-to-large-scale CO2 heat pump series. This model is engineered to meet medium to high-volume hot water demands, utilizing CO2 as an eco-friendly refrigerant, combined with advanced variable frequency technology. It consistently delivers hot water up to 75°C, significantly reducing operational costs and environmental impact. This device has the functions of heating, cooling and generating hot water at the same time. Its reliable performance make it an excellent solution for replacing traditional boilers and achieving green heating.

• Natural Environmental Protection Refrigerant:

  This heat pump exclusively utilizes R744 (CO2) as its refrigerant. CO2 is a natural substance with an Ozone Depletion Potential (ODP) of 0, meaning it does not harm the ozone layer, and a Global Warming Potential (GWP) of just 1, which is significantly lower than conventional refrigerants. This makes it an incredibly eco-friendly choice, as it is non-toxic, non-flammable, and ensures no pollution to the environment throughout its lifecycle.

  
  

• Efficiency and Energy Conservation Performance：

  By leveraging transcritical thermodynamic cycles, CO₂ heat pumps achieve a coefficient of performance (COP) >4.0 under standard conditions, with minimal efficiency losses at low ambient temperatures. Compared to conventional heating systems, they reduce energy consumption by >50%, thereby enhancing the overall energy efficiency of thermal systems.

  
  

• Excellent High-Temperature Heating Performance:

  The KRF-120IIC is engineered to deliver high-temperature hot water efficiently. It is capable of achieving a maximum water outlet temperature of up to 75 ℃. This high output temperature makes it exceptionally suitable for applications requiring hotter water, such as radiator-based heating systems in residential or commercial buildings.

  
  

• Wide Range of Application:

  With an effective operating range in ambient temperatures from −35 ℃ to 20 ℃, the KRF-120IIC is highly adaptable and suitable for heating needs in various climatic regions, including those with prolonged cold seasons. This wide operational flexibility ensures its performance across different geographical locations and seasonal changes.

  
  

• Robust Components:

  The KRF-120IIC is built with high-quality, durable components to ensure long-term reliability and performance. Key components include a jacketed water heat exchanger for efficient heat transfer, an aluminum fin for copper tube air heat exchanger for optimal heat absorption from the air, and a semi-enclosed reciprocating (variable frequency)/R744 compressor which is specifically designed for CO2 refrigerant to ensure stable and efficient compression.

• Transportation: 

  In the field of new energy vehicles, carbon dioxide heat pump air conditioning systems can enhance battery life in low-temperature environments. At present, the Volkswagen ID series models are equipped with carbon dioxide heat pump air conditioning.

  
  

• Residential and commercial buildings: 

  Capable of stable heating at -45 ℃, providing centralized heating or individual heating for cold regions, and compatible with various forms such as radiators and underfloor heating at the end.

  
  

• District Energy & Smart Grid Integration：

  As key components of modern energy systems, CO₂ heat pumps seamlessly integrate with district heating networks and multi-energy hubs. Their intelligent energy management enables synergistic power-heat coordination and tiered energy utilization, significantly enhancing community heating performance while driving the decarbonization of urban energy infrastructure.

  
  

• Hospitality Sector: 

  This model is perfectly suited for mid-sized hotels, resorts, and conference centers, providing comprehensive hot water solutions for guest rooms, large kitchens and dining facilities, on-site laundry operations, and integrated spas or wellness centers. It efficiently handles the fluctuating demands of high occupancy and peak service times.

  
  

• Commercial & Mixed-Use Developments: 

  Suited for mid-sized shopping centers, multi-story office complexes, and integrated mixed-use buildings that require centralized hot water for tenant spaces, public restrooms, extensive food courts, and amenity areas like fitness centers or communal kitchens. It offers a scalable and energy-efficient solution for diverse demands.

Q1. What is the difference between CO ₂ heat pump and ordinary air conditioning/heat pump?

A: Ordinary heat pumps can only produce hot water up to around 60 ℃, and the heating effect is poor when it is cold in winter. The CO ₂ heat pump is like a 'super heat pump', capable of producing hot water above 90 ℃, and can also work stably at -20 ℃ in winter, making it more environmentally friendly. (The refrigerant used is natural carbon dioxide)

Q2. Does the system fail in extremely cold winters?

A: Conventional heat pumps may experience performance degradation at -10 °C, whereas CO₂ heat pumps maintain normal operation down to -25 °C (as validated in Nordic regions and Canada). However, efficiency may marginally decline under prolonged extreme weather.                                                                                                                             

Q3. Does it fail in extreme cold?

A: Unlike standard heat pumps (struggle below -10°C), CO₂ models operate reliably to -25°C.

Q4. What is the minimum order quantity (MOQ) ?

A: 1 units.

Q5. Do you provide OEM or private labeling?

A: Yes. We offer OEM/ODM services, including: Logo printing and Custom packaging.

Q6. Do you offer technical training and support?

A: Yes. We provide: Online and on-site training for sales and technicians, Detailed installation manuals and wiring diagrams, Troubleshooting guides, Remote video support during first installations,  etc.
