Study Notes
HFO and LO Purifiers
Overview
HFO (Hydrofluoroolefin) and LO (Lubricant Oil) purifiers are used to remove impurities and contaminants from refrigerants and lubricants respectively, ensuring the efficient and safe operation of refrigeration and air conditioning systems.
HFO Purifiers
Functionality
- Remove impurities, such as moisture, air, and contaminants, from HFO refrigerants
- Prevent corrosion and damage to system components
- Maintain system performance and efficiency
Types of HFO Purifiers
- Desiccant-based purifiers: use a desiccant material to absorb moisture and contaminants
- Activated carbon-based purifiers: use activated carbon to absorb impurities and odors
- Coalescing purifiers: use a coalescing filter to remove oil and other contaminants
LO Purifiers
Functionality
- Remove impurities, such as moisture, dirt, and contaminants, from lubricating oils
- Prevent corrosion and damage to system components
- Maintain system performance and efficiency
Types of LO Purifiers
- Centrifugal purifiers: use a spinning filter to remove impurities and contaminants
- Cartridge-based purifiers: use a replaceable cartridge to remove impurities and contaminants
- Vacuum purifiers: use a vacuum to remove impurities and contaminants from the oil
Comparison of HFO and LO Purifiers
- Both types of purifiers are designed to remove impurities and contaminants from refrigerants and lubricants respectively
- HFO purifiers are typically used for refrigeration and air conditioning systems, while LO purifiers are used for lubricating oils
- The type of purifier used depends on the specific application and system requirements
