Dear Customer,
The trend towards the use of natural refrigerants as the main alternative to HFCs is clear in the light commercial market. The use of Isobutene in household refrigerators is already standard in most countries due to its low GWP and better efficiency. Following this trend, Propane is becoming the most widely used and best alternative for light commercial applications. It allows F-Gas regulation deadlines to be met and together with R600a provides a definitive solution.
The only drawback is the refrigerant charge limit that is currently restricting its use in some applications. In this respect, there is a new regulation under discussion that could solve this weakness of Hydrocarbons. In the meantime, a lot of new blends are arriving on the market offering temporary solutions and creating confusion. Most of these new refrigerants are not direct replacements for current refrigerants and not as efficient as Hydrocarbons.
We saw in the last ATMOsphere conferences, at Berlin and Madrid, that the market is more and more convinced of the use of natural refrigerants as the best solution. For example, at Huayi Group we have a complete range of compressors working with R600a and R290 covering different applications and a wide range of cooling capacities and voltages. Most of our new developments go in this direction, combining natural refrigerants with more efficient solutions, such as variable speed compressors.
Next year, we will be launching a new product following these two main aspects to meet market requirements.
