The European Commission today adopted a Communication reaffirming the EU’s commitment to accelerated climate ambition. Preparing for the Climate Action Summit by the United Nations Secretary General in New York on 23 September, the Commission recalls that the European Union has been at the forefront of global climate action, negotiating an inclusive international framework to … Read more
It is a fluid circulating to transport energy inside air conditioners, refrigerators, and heat pump hot water heaters. It is a very important substance which hits blood if it says in man. As a refrigerant, fluorocarbons (carbon and fluorine compounds) are used mainly, and it is generally referred to as fluorocarbons. Fluorocarbons were developed for … Read more
In the table below, cfc, HCFC, and HFC-based fluorocarbons, typical refrigerants, are shown. There are various types of fluorocarbons in this series, and each refrigerant has a refrigerant number. Looking at this table, we can see that the coefficient of ozone depletion (ODP) is 0, but the global warming coefficient (GWP: relative value when CO2 … Read more
Air conditioners, refrigerators, and heat pump water heaters are all driven with the same operating principle. Figure 1 shows the state that the air conditioner is doing the air conditioning as an example. First of all, the operating principle is explained based on this operation state. The evaporator as a heat exchanger, the condenser, the … Read more
Refrigerants and Environmental Problems Ozone depletion problem The ozone layer is a dense layer of ozone (O3) in the upper layer of the atmosphere. It absorbs harmful ultraviolet rays contained in sunlight and plays a role in protecting the life of the earth. In the 1970s and 80s, it was discovered that the ozone layer … Read more

Features HFO-1123, the main component of AmoleaX and Y, has zero ozone depletion coefficient (ODP) and a global warming coefficient (GWP) is less than or equal to 1, and has a very low impact on the global environment. Although this HFO-1123 has very high performance in refrigerant performance and environmental performance, it was known that … Read more
