The member States of the European Union have come an agreement to protect the environment through the reduction of greenhouse gas emissions. Therefore they have established a new F-gases regulation in 2014 that substitutes the initial regulation adopted in 2006. The new F-gas regulation which came into force on 1st of January of 2015, incorporate stronger directives about the use and recycling process of the fluorocarbon gases, as well as the business conditions and some regulations about the equipment which operate with these gases. The goal is to reach a gradual reduction of the usage of the HFCs gases in the HVAC&R installations, the intention is to reduce by – 37% in 2020 and by -79% in 2030. These ratio-reduction is measured in relation with an equivalent of CO2 emissions.

In this article we are going to compare some of the HFOs (Hydro-Fluoro-Olefins) which substitutes to the HFCs (Hydro-Fluoro-Carbon) refrigerants. The main attributes of the HFOs are: its low GWP (Global Warming Potential) and its better performance in comparison with HFCs.

Nowadays one of the alternatives for HFC-134a is the HFO-1234yf. HFO-1234yf has a GWP less than 5. This GWP is 99.9 percent lower than HFC-134a, the current refrigerant in use. And a substitute for R-410A is DR5, the GWP is 2008 vs 675, respectively.

In the following chart you will see a brief performance comparison between the refrigerants R410A vs DR5, and R134A vs 1234yf.

The coefficient of performance (COP), is an expression of the efficiency of a heat pump. The COP is defined as the ratio between the power (kW) coming from the heat pump as refrigeration or heat, and power (kW) that is supplied to the compressor.

In the development process Climetal offers its customers a Simulation Software for Microchannel Heat Exchangers. In this Software you can calculate the performance of your MCHEx with the new refrigerants R1234YF R1234ZE R245FA R32, among others. Contact us at climetal@climetal.com and request the username and password for free access to our Calculation Program.

Climetal Microchannel Heat Exchangers are the best option for your systems, they completely accomplish with the new EU Refrigerant Gas Regulations, let’s take a glance of some of their characteristics.

The reduced dimensions of CLIMETAL MICROCHANNEL HEAT EXCHANGERS in comparison with tube and fin exchangers, allow you to decrease the amount of refrigerant used in your system at least by a 30% and still increase both performance and your total system efficiency. Therefore your customer will pay less for refrigerant government fees. In summary, your systems will be more environmentally friendly, in addition with remarkable savings in the overall operation costs as in your production process and in the future maintenance of the system.

The manufacturing process of CLIMETAL heat exchangers assure a leak free joints products than Cu&Al heat exchangers. Climetal MCHEx are manufactured with alloys specially developed for this technology and flux brazed in an inert atmosphere to create a homogenous chemically steady assembly with leak free joints. Climetal products guarantee great savings in leak detection systems and reductions in the environmental impact.
