Regulatory support

HVAC systems - and the refrigerant they use - are coming under increasing pressure to improve their environmental impact. As specialists in the field, we stay aware of evolving regulations and guidance, so you don't have to.

Regulatory support

Compliance support: stay ahead of changing regulations

With refrigerant transition, flammability, and energy standards to consider, there's a lot to think about - and the rules are always changing. Here are just a few of the areas where Lennox can help.

Refrigerant Transition and F-gas

Many of the refrigerants used in HVAC systems are greenhouse gases – often hundreds of times more powerful than CO2. So they’re subject to increasing limits and regulation, based on the global warming potential (GWP) of each refrigerant. Practically, these “F-Gas” rules affect your system in several ways, such as:

Bans on some uses of high-GWP refrigerants

Inspection and leak detection requirements

Advancing quotas based on GWP level, limiting refrigerant supply

CO2e Taxation and Checks

CO2e means “carbon dioxide equivalent”. Where a refrigerant’s GWP measures its climate impact compared to the same amount of CO2, your CO2e is the total potential impact of all the refrigerant in your system – so it’s the refrigerant’s GWP multiplied by its charge.

This is important for two reasons:

A growing number of countries are introducing taxes based on CO2e

Your CO2e determines your inspection and leak detection arrangements.

PED, Flammability and A2l Refrigerants

Many of the modern, low-GWP refrigerants used in today’s HVAC systems – such as R32 – have a flammability classification of A2L. This means they’re mildly flammable, but have a low burning velocity.

With the precautions outlined in the Pressure Equipment Directive (PED), these refrigerants are very safe to use. The directive gives guidance on:

Refrigerant charge limits

System design and use

Location and ventilation
