CO2 Heat Pumps available from Klima-Therm

WHY CHOOSE CO2 HEAT PUMPS?

  • Environmentally friendly: CO2 (R744) is a natural refrigerant with zero ozone depletion potential and minimal global warming impact. 
  • Outstanding performance: our systems are capable of producing very high temperature for domestic hot water (DHW), sanitary water or for industrial processes. 
  • Versatile application: from air-to-water to water-to-water configurations, our CO2 heat pumps adapt seamlessly to any water system for ease of installation.

EXCEPTIONAL THERMODYNAMIC PERFORMANCE

Among the many benefits of using CO2 as a refrigerant are its high thermodynamic performance and a virtually zero impact on the environment. 

Choosing a CO2 based system solves any concern relating to international restrictions and regulations applicable to the use of high GWP (global warming impact) refrigerants and helps to preserve a healthy environment by avoiding harmful emissions to the atmosphere.

Engie range:

  • Available from 150 to 1,500kW
  • Water-to-water only
  • More suited to industrial applications
  • Engie high temperature heat pumps provide hot water temperatures of up to 110°C. 
  • Low heating return temperatures in the so-called ‘transcritical’ CO2 recycle process result in lower energy loss than conventional heat pumps with a subcritical cycle.
  • Heating processes such as drinking water preparation and process water heating allow low return temperatures and can therefore be implemented with higher-performance CO2 heat pumps.

FAQs:

How do CO2 heat pumps work?

CO2 heat pumps utilise carbon dioxide (CO2) as a refrigerant to extract heat from the surrounding environment, such as air or water. This heat is then transferred into a heating system, providing hot water for various applications.

Are CO2 heat pumps environmentally friendly?

Yes, CO2 heat pumps are considered environmentally friendly because they use CO2 as opposed to fluorinated gases (F-gases), such as hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons (HCFCs). These gases have been traditionally used in refrigeration and air conditioning systems but are being phased out due to their high global warming potential (GWP). CO2 is a natural refrigerant with a low GWP and zero ozone depletion potential (ODP), which helps to reduce greenhouse gas emissions.

What are the advantages of CO2 heat pumps compared to traditional systems?

CO2 heat pumps offer several advantages, including higher energy efficiency, lower operating costs, reduced carbon emissions, and compliance with environmental regulations. They also provide reliable heating performance even in extreme weather conditions.

Are CO2 heat pumps suitable for all types of buildings?

CO2 heat pumps are versatile and can be used in various commercial, industrial, and residential buildings. However, the suitability depends on factors such as building size, heating requirements, and environmental conditions.

What maintenance is required for CO2 heat pumps?

As with all HVAC systems, regular maintenance is essential to ensure the optimal performance and longevity of CO2 heat pumps. This includes cleaning filters, inspecting components, checking refrigerant levels, and scheduling professional servicing as needed.

Are CO2 heat pumps cost-effective?

While the initial investment for CO2 heat pumps may be higher than traditional systems, they offer long-term cost savings through lower energy consumption and reduced operating expenses. Additionally, incentives and/or grants may be available to offset installation costs.

Can CO2 heat pumps provide both heating and cooling?

Yes, some CO2 heat pump systems are designed to provide both heating and cooling capabilities. These systems can efficiently heat water for space heating or domestic hot water and provide cooling for air conditioning or process cooling.
