A cool –
uncool story

Since the German breweries in the early 1800s needed cooling for their beer brewing processes, natural refrigerants have been used in cooling systems.

But, from the 1930s and forward, synthetical mixtures of various CFC’s (Chlorofluorocarbons) were introduced as a “safer” alternative to CO₂. Today we know that Chlorofluorocarbons from refrigeration have caused large holes in the protective Ozone layer around our globe, and they still do.

Whereas  CFC’s destroys the Ozon layer, the newer HFC’s (Hydrofluorocarbon), used worldwide don’t impact the Ozone layer, but they contributes immensely to global warming, and some of them are in a PFAS group that five EU countries intend to restrict.

The newest synthetic refrigerants HFO’s (hydrofluoroolefin) are marketed as environmentally friendly, but have lately been classified as PFAS, also known as “for ever chemicals” that the five EU countries intend to restrict. Numerous studies have shown that not only do HFO’s contribute immensely to global warming, but they also pollute the drinking water.

How can CO₂ reduce CO₂ emissions?

The following is an attempt to give you all facts you need to understand Winns environmentally friendly heating and cooling technology with natural CO₂.

CO₂ is a naturally occurring substance contributing to global warming, used as a unit of measure for other non-natural substances in regard to the Global Warming Potential (GWP). 1 GWP equals 1 kg of CO₂.

Let’s compare: A typical refrigeration system contains 50 kg of HFC gas (like R134 with a GWP of 1480). If this gas is leaking out, the atmosphere has to deal with equal to 74.000 kg of CO2. And this is just a small refrigeration system. If we use CO₂ as a refrigerant in the same size system, 50 kg CO2 in is 50 kg CO₂ out.

So easy. So important.

How can CO₂ reduce CO₂ emissions?

  • It is a virgin technology: No, Since 2000 CO₂ systems has been used in supermarkets, first in the Nordic countries, and are now found worldwide. If you walk into a grocery store in Norway today it is a 90% chance that CO2 is the refrigerant keeping your milk cold.
  • Higher investment costs: Yes, due to the higher working pressure ratio of CO₂, the components are more expensive, but also more robust and has a substantial lower maintenance cost and longer lifetime. The investment also ensures that you don’t have to replace your system soon in the near future due to phase-out of the refrigerant.
  • It’s dangerous: No, CO₂ is non-toxic, non-flammable and non-explosive, safety group A1. Although it has a slightly lower detection threshold compered to other refrigerants due to its properties. Other chemical refrigerants are oxygen displacing, whilst CO2 effects the breathing.
  • Big compressors and pipes: No, in fact the thermal properties of CO₂ requires much smaller tubing than a conventional refrigerant like the R134a.
  • It does not fit my application: Yes, it probably does, there are few refrigeration or heating application not suited for our systems.
  • It’s not as effective: For most offshore installations it will be at least as effective as conventional, pending type of application.
  • High maintenance cost: No, experience with these systems over the last decade shows the opposite, CO₂ systems are more rigid and has stronger components and piping compared to conventional systems due to the higher operating pressure of CO₂.
  • Availability is low: No, CO₂ systems spares are on the shelf worldwide, it is more than 30.000 of these systems running W.W. PT.
  • There is going to be a drop-in replacement refrigerant available soon: No, all the combinations in the periodic system have been tried, there will never be an environmentally safe synthetic refrigerant, not ever! Only NatRefs, like: Ammonia R717, Water R718, Hydrocarbons R270, R290, R600…, and finally CO₂ are environmentally safe.
