What Is the Difference Between Direct and Indirect Leak Checking for F-Gas Inspections?

“F-Gas regulation” is a term that is given to new regulation EC517/2014, first adopted in 2014.

EU F-Gas regulation sets out the correct requirements for checking and maintaining refrigeration systems, air conditioning, and other heat pump technology. The laws were introduced to control emissions stemming from fluorinated greenhouse gases.

F-Gases can be damaging ozone depleting substances, so the regulations are important to control global warming.

Within the documentation is a set of leakage checking requirements for SRACHP equipment.

Current F-Gas regulation outlines the fact that all systems require a leak test regularly. How often you need to perform these checks depends on the system charge and size, as well as whether fixed leak detection systems are installed.

Let’s explore the difference between certain types of leak detection for F-Gas Inspections.

Indirect F-Gas Checking

Indirect checks are those that analyse the following systems and components:

  • The pressure of the system.
  • The temperature of the system.
  • The run current of the compressor.
  • Liquid levels.
  • A visual inspection for leaks and stains that have come from leaks.
  • Recharge volumes (not required for every system).
  • Checking for any noise, vibrations or even ice forming in areas of the system.

Direct F-Gas Checking

Direct checking of the air conditioning or refrigeration systems includes:

  • Checking the circuitry and any components within the system which can potentially leak gas.
  • Handheld leak detector devices that can detect compromises in the system.
  • Using UV detection fluid or dye in circuitry to see if any leaks are occurring.
  • Bubble solution methods of checking leaks.
  • Using nitrogen without oxygen, due to the molecular structure of nitrogen atoms, to put pressure within the circuit and detect leaks.

 

Fixed Systems

As well as direct and indirect F-Gas checks, there are fixed leak detection systems you can install. This equipment detects any leaks within your system and can alert operators or companies you employ to service your gas equipment.

Under F-Gas regulations, air conditioning systems, refrigeration systems and heat pump equipment containing 500 tonnes CO2e or more of HFC refrigerant legally require a detection system for leaks to be installed.
