Manufacturers now make AC units with these better refrigerants. People get cool air and our earth stays safe.
The Role Of Refrigerants In Ac Systems
Think of refrigerants as the lifeblood of air conditioning units. These special substances absorb heat from indoors and release it outdoors. This process keeps homes cool even during hot summer days. Modern AC units use advanced refrigerants for better efficiency and to minimize environmental harm.
How Refrigerants Facilitate Cooling
Refrigerants absorb heat from the air inside your home. They then travel to the outside unit where they release the heat and get cool again. This cycle repeats itself, maintaining a steady cool temperature inside.
In simpler terms:
- Indoor unit pulls in warm air.
- Refrigerant absorbs the heat.
- Cool air blows back into the room.
- Refrigerant, now warm, moves outdoors.
- Outdoor unit dumps the heat.
- Cycle starts again.
Environmental Impact Of Traditional Refrigerants
Older AC units used refrigerants like CFCs and HCFCs. These harm the ozone layer and contribute to global warming. To address this, new units now incorporate eco-friendly refrigerants.
| Old Refrigerant | Environmental Issue | New Refrigerant | Benefit |
|---|---|---|---|
