Manufacturers’ body publishes safe handling guidance for use of flammables in compression refrigeration circuits
Components body Asercom has issued guidelines on the use of flammable refrigerants. The association said the handling of components for flammable refrigerants ’involves numerous risks’ but noted that they are very important for achieving the objectives of the F-Gas Regulation, thanks to their low-GWP characteristics.
Asercom said it has published a comprehensive guide for the safe handling of components in the use of flammable refrigerants so as to provide experts, manufacturers and installers of systems that are operated in non-hazardous areas (no ATEX zones) with a handling recommendation. Specifically, the guideline aims at the safe handling of components used in compression refrigeration circuits with flammable refrigerants.
Asercom President Wolfgang Zaremski said: ”Although safety regulations document well how corresponding systems must be built, installed and maintained, the component manufacturers in Asercom have noticed a high degree of uncertainty among refrigeration and air conditioning specialists when dealing with flammable refrigerants.”
The body added: ”Flammable refrigerants have been used in millions of household applications for decades. The filling quantity in household appliances is limited to 150 g per system. Industry and the associated service sectors are now faced with a new challenge: the increased use of flammable refrigerants means that larger fill quantities are required, which, if handled incorrectly, pose a significantly higher risk potential.”
The guidance outlines the specific conditions under which flammable refrigerants are allowed to be used, including the fact that the installer must always carry out a comprehensive risk assessment of the installation. This means that he must design the installation in accordance with the safety requirements described in the application-specific safety regulations. Asercom added that it provides appropriate instructions in its guideline to assist in specifying the requirements for handling components for flammable refrigerants.
It said: “It is therefore advisable to prepare early for the changeover to flammable refrigerants. Appropriate training and the resulting skills are crucial for safe handling.”
