Everything you need to know about the inspection of cooling systems and heat pumps

What is leak detection?

Leak detection is an inspection performed to identify refrigerant leaks in systems at an early stage. It is a mandatory measure for installations containing fluorinated greenhouse gases, as these gases are harmful to the environment.

Why is leak detection mandatory?

Fluorinated refrigerants have a high global warming potential. Refrigerant loss leads to higher operational costs and reduced efficiency. Both European and national regulations require mandatory leak detection.

Which installations are subject to this obligation?

According to Belgian legislation:

• ≥ 5 tonnes CO₂ equivalent: Annual leak detection required

• ≥ 50 tonnes CO₂ equivalent: Biannual leak detection required

• ≥ 500 tonnes CO₂ equivalent: Quarterly leak detection required

For systems containing more than 500 tonnes CO₂ equivalent, a continuously monitored leak detection system is also mandatory.

How does a leak detection inspection work?

Preparation

Ensure that the system is accessible and relevant technical documentation is available.

Inspection of the refrigerant circuit

• Perform visual inspections and check for potential leaks using specialised equipment

• Use electronic leak detectors or other advanced methods to identify refrigerant loss

Reporting findings

• A detailed report is drawn up with the results of the inspection

• Recommendations for further action or repairs are provided if needed

How often must leak detection be carried out?

The frequency depends on the quantity of CO₂ equivalents in the refrigerant:

• ≥ 5 tonnes CO₂ equivalent: Annual leak detection required

• ≥ 50 tonnes CO₂ equivalent: Biannual leak detection required

• ≥ 500 tonnes CO₂ equivalent: Quarterly leak detection required

For systems with more than 500 tonnes CO₂ equivalent, a permanently installed and continuously monitored leak detection system is mandatory.

Frequently asked questions about heat pumps and cooling systems

Why is leak detection important?

Leak detection helps prevent refrigerant loss, reduces environmental damage, and ensures compliance with legal requirements.

Who is allowed to carry out leak detection?

Only certified technicians with the proper equipment and authorisation may perform leak detection on systems with refrigerants.

What happens if my installation is not maintained?

Failure to perform leak detection may result in environmental harm, increased operational costs due to refrigerant loss, and legal penalties.
