The school engaged Zenergi’s technical division to evaluate whether its systems were working efficiently and to ensure that the school was compliant with TM44 Air Conditioning Inspections.
The refrigerant used in air conditioning systems is thousands of times more damaging than
Chemicals called Hydrofluocarbons (HFCs) are used in air conditioning for cooling but have a Global Warming Potential (GWP) thousands of times greater than CO₂, should they leak. Some HFCs are more than 13,000 times more harmful to the ozone layer, with the most commonly used typically 3,500 times more damaging.
This should be the most important consideration for schools evaluating the need to commission
a TM44 inspection.
