To avoid use and emissions of both hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs), a variety of climate-friendly, energy efficient, safe and proven alternatives are available today. In fact, for most applications where HFCs and HCFCs are still used in the world, more climate friendly alternatives could potentially be used. However, due to different thermodynamic and safety properties of the alternatives, there is no „one size fits all“ solution. The suitability of a certain alternative must be considered separately for each category of product and equipment and in some cases also taking into account the level of ambient temperature at the location where the product and equipment is being used.
The climate impacts of a substance is commonly expressed as the global warming potential (GWP); the lower the GWP, the more climate-friendly. The GWP values of the various HFCs or HCFCs are generally in the thousands. Conversely, GWPs of climate-friendly alternatives are much lower. The most commonly used alternatives to HFCs and HCFCs and their characteristics are listed in the table below.
|Alternative||Global Warming Potential (GWP)||Properties to be addressed||Commercial availability|
|CO2 (R744)||1||High pressure||Immediate|
|Ammonia (NH3, R717)||1||Toxic||Immediate|
|Water (R718)||1||No risks||Immediate|
When seeking alternatives to HFCs and HCFCs in specific applications, it is the total greenhouse gas emissions linked to the use that counts. Hence, suitable climate-friendly alternatives must show sufficiently high energy efficiency so that the reduction in direct emissions from the alternatives to HFCs and HCFCs is not offset by higher indirect emissions from energy use
Today most of the HFCs are used in refrigeration and air conditioning (AC) equipment. In developing countries (Article 5 countries under the Montreal Protocol), R22 (an HCFC) is still the most important refrigerant currently used in this sector. In those countries, demand for refrigerants is expected to increase significantly in the short and medium term, to satisfy expected growth in the use of AC and supermarket refrigeration, in particular.

Globally, 197 countries are working to amend the international Montreal Protocol agreement to phase out HFCs. The phase-down could begin as early as this year.
HFCs are man-made chemicals, developed to replace chloroflourocarbons (CFCs) in refrigeration systems, which deplete the ozone layer and were banned in 1992 by the Montreal Protocol. While HFCs don’t deplete the ozone, when used as refrigerants, for example, in air conditioning systems in both vehicles and buildings, they are potent greenhouse gases. Depending on the exact type of HFC, they can be up to 20,000 times more powerful than carbon dioxide — and have atmospheric lifetimes of up to 260 years. To control emissions from fluorinated greenhouse gases (F-gases), including hydrofluorocarbons (HFCs), the European Union has adopted two legislative acts: the ’MAC Directive’ on air conditioning systems used in small motor vehicles, and the ‘F-gas Regulation’ which covers all other key applications in which F-gases are used.
Limiting the total amount of the most important F-gases that can be sold in the EU from 2015 onwards and phasing them down in steps to one-fifth of 2014 sales in 2030. This will be the main driver of the move towards more climate-friendly technologies
The F-gas Regulation anticipated a global phase-down of the consumption and production of HFCs under the Montreal Protocol on substances that deplete the ozone layer.
The Regulation will also affect other markets, in particular countries exporting to the EU. Through increased demand for climate-friendly technologies, the new Regulation creates new business opportunities and will accelerate innovation and economies of scale in producing such technologies, thus lowering their costs. In this way, the Regulation helps to promote consensus on a broader international agreement.
While confirming the EU’s position as a global leader in taking strong measures on F-gases, the new legislation is also meant to inspire others to take action. A number of countries are already developing similar approaches. (source: ec.europe.eu)
We worked hard on it. Since we decided to start this company to leave old structures behind we faced a lot of challenges. But as a sailor can’t sail without wind we set our sails with only one mission: we are convinced that if there is no one who cares about this world, there will be at least one: CoolnTool. We saw a major opportunity in the new regulations of European Union. We are small, agile and a well educated team. We will take chance of this turning tide. While others complaining, we are working for the benefit of our customers.
Togehter with our partners we have more than 100 years of experience in sustainable refrigeration. Each one is a specialist on its field. This is a reliable network where you can trust in.
To provide this in the best way possible we did a research. We searched the whole continent for the best sustainable, environment-friendly, efficient refrigeration technology and keep going with this. We found partners who are sharing our attitude. We are working together to create an certain impact. If everything will go right we will leave this world with a green fooprint. To ensure the best working supply chain we worked together with a lot of specialists to implement communication channels, an ERP system and a lot more – so called Industry 4.0. Together we will make environment great again. Challenge us!
