Just a few years ago air conditioning units were a symbol of luxury, installed exclusively in selected buildings. Today, both modernized and new buildings are fitted with air conditioning. Moreover, VRF air conditioning systems are now becoming a standard. Let’s take a closer look at what’s so special about this solution and why it may be worth considering. What …

When deciding to purchase a heat pump, we usually pay attention to its parameters. While we are mostly interested in the heating power of a device and its price, we are rarely interested in other features of a heat pump. One of the worthwhile aspects when selecting a heat pump is the refrigerant used in …
The legal market for refrigerants with high GWP (Global Warming Potential) is shrinking year by year. This is all because of the quotas. Pursuant to legal regulations, i.e. the EU F-Gas Regulation and the Polish F-Gas Act, the number of tones of carbon dioxide equivalent (t CO2eq) of refrigerants that may be imported into the …
Withdrawal of refrigerants with high GWP values and introduction of synthetic refrigerant alternatives does not always progress smoothly. This is mostly related to the flammability of the new refrigerants. As slightly flammable fluids (class A2L in accordance with the EN 378-1+A1 standard), refrigerants such as R32 or R1234ze(E) cannot be used for retrofitting existing devices …
When a new split air conditioner model is launched on the market, the refrigerant used is usually R32 – difluoromethane (CH2F2). Although this is a fresh solution – pioneers decided to design and sell devices with this refrigerator only in 2013 – R32 split air conditioners may nowadays constitute even half of the European market …
The term “hydrofluoroolefins” (HFO), which are also often referred to as the “fourth generation refrigerants”, entered the cooling technology industry in 2013, when common use of the refrigerant R1234yf was started in automobile air conditioning. It was only a matter of time before the fourth generation refrigerants appeared – the previously common refrigerants from the …

The R410a refrigerant has a high GWP value (2088), in line with European Union guidelines, it should be eliminated from use. At the split air conditioning market, R410a is less and less appropriate, however, it is still strongly positioned as the preferred refrigerant for A1 VRV / VRF solutions. Classification – A1 is a key …
