How do you contribute to the destruction of our enviroment by insufficent service of your cooling unit?
The cooling agent circulating in cooling units can have a direct impact ont he enviroment, if by possible damage, or malfunktion leaks into the air. Some agents contribute to the decay of the ozon layer, others lead to global warming, accelerating the glas house effect.
An indirekt impact is trough the energy consumption of the air condotioning and cooling units, as energy generation leads to CO2 emission, independent if we use the units from elektric networks, or own engines. Carbon.dioxide leads to global warming.
To the understanding of the danger of leaked cooling agents the next illustration can help
GWP= Global Warm Potencional
R404a refrigirating agent GWP=3780
1GWP = 1 Kg CO2
Carbon-dioxide emission of an average car, like a Ford Focus 150g/km
1000 g= 1 Kg CO2
6,7 km x 150 g/km = 1005g so you have to drive 6,7 Km, so your car has an emission of 1 Kg
1kg R 404a = 3780GWP X 6,7km = 25326km
So you would have to drive 25326km to have the same emission as 1 Kg of R404a cooling agent. Usual direkt drive units have 1,5-2 Kg, while trailers units have 7-9 Kg of R404a load on avarage.
This way it is apparent why regular check ups on cooling units are important.
Companies are using high resources to find agents with a global warming factor as low as possible. In January 2017 Carrier Transicold introduced R452a, to replace R404a, that has the same performance parameters, but almost 50% less GWP.
