Understanding Refrigerant Sorts
Refrigerants are the lifeblood of a fridge, chargeable for absorbing warmth from the within of the equipment and releasing it outdoors. Over time, refrigerants can leak or develop into depleted, resulting in a decline in cooling efficiency. Understanding the several types of refrigerants and their properties is essential for efficient upkeep and troubleshooting.
Pure Refrigerants
Pure refrigerants happen naturally within the setting and have minimal environmental impression. They embrace:
- Ammonia (NH3): Extremely environment friendly and non-flammable, however poisonous and corrosive.
- Carbon dioxide (CO2): Environmentally pleasant, however requires excessive pressures and specialised tools.
- Propane (C3H8): Flammable, however comparatively cheap and simply obtainable.
Artificial Refrigerants
Artificial refrigerants are man-made chemical substances designed particularly for refrigeration functions. Frequent varieties embrace:
