FAQ: Which Refrigerant is Suitable for Low Pressure Systems

Frequently Asked Questions

What should be on and what should be off during a vapor removal from a low pressure refrigeration system

During a vapor removal process from a low pressure refrigeration system, it is crucial to ensure that certain components are turned on while others are turned off. Here’s a breakdown of what needs to be on and what needs to be off:

Components to be turned on:
  • Low-pressure receiver: The low-pressure receiver collects the refrigerant vapor and separates it from any remaining liquid refrigerant. This component should be turned on to enable the vapor removal process.
  • Vapor pump: The vapor pump plays a critical role in the removal of vapor from the system. It should be turned on to facilitate the suction of vapor from the low-pressure receiver.
Components to be turned off:
  • Compressor: It is important to turn off the compressor during vapor removal to prevent any further circulation of refrigerant in the system.
  • Condenser: The condenser is responsible for releasing heat from the refrigerant. To avoid any interference with the vapor removal process, it should be turned off.
  • Expansion valve: This component controls the flow of refrigerant into the evaporator. It should be turned off, allowing the vapor to be efficiently removed from the system.

Is R123 a low pressure refrigerant

Yes, R123 is indeed a low pressure refrigerant. It belongs to the hydrochlorofluorocarbon (HCFC) family and is commonly used in low pressure systems. R123 offers desirable thermodynamic properties that make it suitable for various cooling applications.

Which refrigerants are considered low pressure refrigerants

Several refrigerants are considered suitable for low pressure systems. Here are some commonly used low pressure refrigerants:

1. R134a:

R134a is widely used in automotive air conditioning systems. It operates at relatively low pressures and offers efficient cooling performance.

2. R404A:

R404A is commonly used in commercial refrigeration applications, such as supermarket refrigeration and cold storage. It is known for its low operating pressure and stable performance.

3. R407C:

R407C is a popular alternative to R22, which is being phased out due to its negative impact on the environment. It operates at lower pressures and has excellent cooling capabilities.

4. R507A:

R507A is a blend of refrigerants that is commonly used in low and medium temperature refrigeration systems. It provides efficient cooling performance while operating at low pressures.

5. R410A:

R410A is a non-ozone depleting refrigerant often used in residential and commercial air conditioning systems. It operates at higher pressures than some other low pressure refrigerants, but still falls within the low pressure range.

These refrigerants offer various advantages for low pressure systems, including energy efficiency, environmental friendliness, and reliable performance.


By addressing these frequently asked questions, we hope to have provided you with valuable insights into low pressure refrigerants. Remember, understanding the fundamentals of refrigerants is essential for ensuring optimal performance and longevity of your cooling systems.
