Extract from Regulation 517/2014 of the European Parliament and Council of 16/04/2014
on evening-effect chlorinated gases repealing Regulation 842/2006
ANNEX III: Prohibitions on placing on the market pursuant to Article 11, paragraph 1

Products and equipment. Where appropriate, the GWP of mixtures containing chlorinated greenhouse gases shall be calculated in accordance with Annex IV, as set out in Article 2, point 6.

Refrigerators and freezers for commercial use (hermetically sealed equipment) containing HFCs with a global warming potential of 150 or more.

Fixed refrigeration equipment containing HFCs with a global warming potential of 2500 or more, or whose operation depends on HFC subdetes, with the exception of equipment designed to cool products to temperatures below -50°C.

The use of a refrigeration plant with compressors driven by inverters.
An inverter refrigeration plant is able to regulate the refrigeration power required by the system by continuously varying the number of revolutions of its components. Such a system allows for:
– operate with a constant evaporation pressure in any working condition;
– to operate with maximum thermodynamic efficiency;
– maximize the efficiency of heat exchangers;
– limit the reaction times of the system;
– increase the useful life of components;
– limit the electrical consumption of machines to a minimum.

Take as an example the case study reported in Table 1 which takes a 25HP compressor as a reference.
From the lines highlighted in blue it can be deduced that a traditional machine can be compared with an inverter machine when compared under nominal conditions. In part-load operation, a traditional machine will instead consume more electrical energy and deliver less refrigeration power at the expense of COP and operating costs.

The new eco-friendly refrigerant range

Use of ultra-low GWP refrigerants
The new range of Keyfrost machines includes the use of brand new ultra-low GWP refrigerants. With a GWP of only 146, the R455A stands as the definitive solution for the future of commercial and industrial refrigeration for low and medium temperatures.
After several tests and studies based on the entire cold chain, it has been demonstrated that the TEWI of machines operating at R455A is also more favorable thanks to the coolant COP but also to the ease of management of machines that do not involve particular complications for the user compared to older machines at R404A.

Safety
The refrigerant used is composed of a slightly flammable azeotropic mixture (A2L according to ISO 817). However, the use of R455A is made safe (in compliance with the main safety regulations) thanks to the particular flammability properties of the refrigerant including:
a) Relatively high lower flammability limit of ’11.8% (LFL);
b) Relatively low upper flammability limit compared to the lower flammability limit 12.9% (UFL);
c) Minimum ignition energy greater than 1000 times that of propane;
d) Flame propagation speed less than 1.5cm/s.
