What is EN 378?
EN 378 relates to safety and environmental requirements in the design, manufacture, construction, installation, operation, maintenance, repair and disposal of refrigerating systems and appliances regarding local and global environments.
What is bs EN378?
BS EN: 378: 2008, 1 Refrigeration systems and heat pumps – safety and environmental. requirements – Part 1: Basic requirements, definitions, classifications. and selection criteria. BS EN: 378: 2008, 2 Refrigeration systems and heat pumps – safety and environmental.
What are F Gas Regulations?
What is F-Gas Regulation? From 1st January 2020, the EU Fluorinated Greenhouse Gases Regulation (also known as the EU F-Gas Regulation) will ban the use of refrigerants with a Global Warming Potential (GWP) of 2,500 or more in certain refrigeration units.
How long should you pressure test refrigerant system?
After all joints are checked for leaks, the piping should remain under 300 psig for 24 hours. After the 24-hour test, the piping should be depressurized and evacuated down to a 1,000-micron vacuum for 30 minutes.
What does F-Gas stand for?
Fluorinated gases
Fluorinated gases (F-gases) are man-made gases used in a range of industrial applications. F-gases are often used as substitutes for ozone-depleting substances because they do not damage the atmospheric ozone layer.
What PSI is required during leak testing?
2. Only, a small amount of refrigerant is required to perform a leak test. A gauge reading of 50 psi is all that is needed.
Why is nitrogen used for leak test?
Using a nitrogen pressure test procedure allows operators to circumvent the challenges associated with other forms of testing. Nitrogen gas possesses unique physical and chemical properties that make it effectively inert. This makes it perfect for leak testing.
What are HFCs and PFCs?
Fluorinated Gases: Hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF6) are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes. Fluorinated gases are sometimes used as substitutes for ozone-depleting substances (i.e., CFCs, HCFCs and halons).
Which is the gas banned for refrigeration?
EPA has banned the R-22. In our medical devices policy , for example, while we don’t allow many items (such as contact lenses), we do allow other items under certain conditions (including certain types of medical instruments). Home AC units use two different types of refrigerants, Freon (R22) or Puron (R410A).
What type of nitrogen is used in HVAC?
MaxxiLine Nitrogen (N2) disposable gas cylinders, are commonly used in the Air Conditioning / Refrigeration industry to purge moisture while repairing pipes.
Why Helium is used in leak testing?
Why use helium for leak testing? Helium is one of the smallest gas molecules and is inert. Being inert, helium is relatively safe to use (rather than hydrogen) and will not react with any of the materials within the part to be tested.
What is a PFC refrigerant?
PFC (perfluorocarbon) refrigerants are fully halogenated hydrocarbons. They only contain fluorine (F) and carbon (C). The ODP of PFC refrigerants is 0, meaning that they pose no threat to the ozone layer. However, they have a notably high GWP value, which means that they accelerate global warming.

What is part 3 of the European standard for refrigeration?
This Part 3 of the European Standard is applicable to the installation site (plant space and services). It specifies requirements on the site for safety, which may be needed because of, but not directly connected with, the refrigerating system and its ancillary components.
